The Package and the Content
As usual, we are looking at the box, which sets a casual look. The color scheme and design of box unique that SilverStone have been using for past years is different from competitor and that’s why SilverStone is stand out in the market. Here, we are seeing box having black and light green color. The SilverStone logo located at the top corner. The middle area is black having model and series info, while the PSU picture is coming from right corner. The bottom area is pretty much greenish with content listed and 80 PLUS Titanium badge at bottom right corner. A decent yet different box styling from SilverStone.
Looking at the back, the box offers great amount of detail related to Power supply. Some common features are listed in multilingual and to our surprise, once again, no English is included, and upon asking, SilverStone representative, Tony, has replied and we are quoting it.
“English feature list is already shown on the “front” side of the box so there is no need for us to repeat them again on the back.”
We moved towards right, there are multiple diagrams presents the major qualities of this power supply. Like there is an efficiency graph showing the maximum and minimum efficiency points. At the bottom area, we see the barcode stickers, safety certifications and a big V1.0 sticker, which tells this power supply is version 1, so if there is any revision to come out then that would be either 1.1 or simply 2, whatever.
Moving towards sides, which reveals the specification details regarding power delivery and cables/connectors. The table tells about this unit has the rated capacity is 700W and peak at 750W, however the actual output that it can deliver is the 696W (12 Volt x 58 amp). It’s an excellent output to say the least. The bottom row pictured with the connectors.
Inside the box, we see a couple of manuals laying on top of the internal packaging. If you’ve followed our reviews, specifically SilverStone power supply, the similar sort of arrangement has been seen in GS 850W PSU, too.
There are two sides of internal packaging. One demonstrates the black foam having PSU inside and right side contains the Accessories box. We move first with unleashing top foam cover, which unleashes the glimpse of PSU, but Interestingly, we also see the SilverStone’s branded dust filter placed on PSU top. The power supply unit is packed in a plastic bag.
On the other hand, the Accessories box in black has the SilverStone logo at top. When we open the box, we found a zipped plastic bag, which contains zipties, and screws. Below to it, we found the modular cables. Unlike the previous packaging, this has a new outlook. The previous packing on accessories is pretty much nothing, but this time SilverStone have implement that right, especially with the inclusion of proper branded box for cables and accessories.
We put together all the components that comes in the box. To be more precise, we listed the items you will receive in the box.
- Power supply
- Accessories Box (cables & Connectors)
- Extra Accessories
While the cables and Connectors are listed as follows:
- 1x MB 24/20P
- 2x CPU 4+4P
- 4x PCI-E 6+2P
- 12x SATA
- 3x Periperal 4P
- 1x Floppy
A Close Look – Exterior
As usual, we are looking at the exterior body first. The power supply is completely black with lead-free paint on it. There is matte black finishing on PSU that has a decent outlook. Not to mention the traditional SilverStone logo engraved on top feels like mandatory on SilverStone PSUs. Strider GOLD series, Platinum and Titanium all comes with the similar logo designed on top.
On one of the side, there is a huge PSU label, which is quite detailed. The truth is, no one actually bothers to read out that much detail from the label, except the power ratings and little precautions. The most important aspect to look at is the DC output specification. It has a single rail +12V that outputs 696W by utilizing 58A. So theoretically, we have a continuous output of 696W.
The other side has a few small stickers, one with barcode and other ones on right are probably test verified, ranking at V1.0 suggesting the version 1 of Titanium series 700W.
On the front, we have the cabling system designed for this power supply. No wonder SilverStone is being popular for its dedicated modular-system outlook. Here, we are experiencing something new and worthy that we haven’t seen in SilverStone PSU in years. Specially made clips mounted on each connector, except the 24P power connector which are truly a nice add-on. This new addition is especially handy to secure the connectors from dust. The MB 24P power connector is in lower row however, without clip, while the PCIe connectors are identifies in Blue and others are in Black (a Traditional SilverStone modular design). Yes, this is how SilverStone design outlook stand out in the market. There is no brainer that fully modular PSUs are the best, which apparently, makes it highly preferred designed verified by PC Enthusiasts.
The backside displaying the look inside through holes, while the 3P AC input on one side. We are sure many of you looking for Power Switch, and to our surprise, there is no Power ON/OFF Switch around AC input. Which apparently an undesired breakthrough for gamers. Although, we don’t see any performance degrade with not having it, but removing the switch from design is simply not helping here.
The fan side is also following with the lead-free paint in black; the grill is black, too, which is tightly fixed with the screws across each end. The white-round warranty void sticker on one side area. Once you tear the seal, you lost the warranty. So be careful with that. A built-in 120mm Fan inside peaks at rated 960 RPM ensures quieter operation even at high load. The rated noise level is 18 dBA minimum.
The PSU is fully modular, so there are separate cables came with the unit. The cables are coated in plastic rubber body, having designed as sleeved flat and black in nature. There is absolutely no complaints on it’s quality. They are standardized and satisfactory.
The standard 20+4P (24pin MB) power connector is well made without adversery.
Looking at the PCI-E cable, the black sleeved flat cable has a blue connector that goes to the PSU.
The peripheral, SATA/IDE, are grouped together in a single bunch.
A Close Look – Interior
It might be the hardest part to tear down the unit, but since we have done the same practice several times, we are ready to do once more. Once we open the PSU by unscrewing all four screws, we see the fan, which has a familiar design with APA141 case fan from SilverStone. The built-in fan is 120mm with model HA1225H12F-Z having DC 12V with 0.58A rating. This fan peaks at 960 RPM and according to specification, the minimum noise level it would generate is 18 dBA. We don’t predict any serious noise level on maximum speed, since the peak point is even below 1000 RPM mark. Besides power efficiency, the ultra-low noise is the key point these days and Silverstone have been doing it brilliantly.
Once we moved inside, we see an impact of significantly compact design one could witness. The Components inside not messing at all. In fact, every tiny and bigger component are arranged and placed in an organized way.
The primary side starts with the AC input, which offers power Input. The power supply supports 110 – 230v, so it covers all type of consumer. The wires wrapped around the AC input closely soldered with the main PCB.
Making way up to primary side, we find a bigger, silver heatsink that usually seen in Enhanced OEM supplies. SilverStone Strider 850W GS had the similar heatsink design, too. The bridge rectifier is quite close to aluminum heatsink, while the main Capacitor is residing next to it. It has all Japanese capacitor as promised in the specification. The Enhanced OEM is not greatly popular, but it does have some reputation in manufacturing Mid to high-end power supplies; some other brands like Antec has used Enhance Electronics for making of their PSUs.
The main capacitor is 560uF, having rating of 105°C – 470vdc. Indeed, a great workout for an 700W PSU and especially when it is to deliver the highest, Titanium, efficiency.
Moving towards the secondary side, we see a transformer in yellow. Besides, there is another add-in control unit that has a DC-DC converter mounted on their separate boards, located behind the secondary heatsink for +3.3 and +5v voltages.
In the middle area, beside the DC-DC converter, there is a combination of Nippon Chemi-con and Rubycon 16V capacitors assisting the +12V rail. The black/dark brown T1652 – 105°C capacitors are around DC-DC converter. Just close to AC input, we also see a Rubycon 16V – 1500uf capacitor. The Enhance Electronics rated this power supply to deliver the continuous power at 40°C but not 50°C, which is understandable as the size of the build defines it. the interior is no doubt well made and soldering work is excellent, too. Enhance Electronics have done a wonderful job here, I must say.
The fan cable leading to the controller PCB and connected with the header under the AC input on main PCB.
The wires for modular cabling is being soldered on the main PCB, and then leading to the modular PCB. The overall design is quite compact, with little spaces in the middle, the unit is smallest in the PSU lineup.

The first and foremost part of this testing is Voltage readings by using digital meter. we took the readings via UNI-T Digital meter. The instrument tells that we are at 230VAC and 50Hz frequency across the tests. To start with, idle testing will be our priority, for which we kept the system in no-usage mode or Idling and noted down the wattage being drawn from wall outlet. About load testing and efficiency, we tortured the system via heavier synthetic applications, Prime95 and Furmark 1.10v combined. The processor, Intel Core i5 6700K 4C/8T overclocked at @4.5GHz, and Graphics card, AMD RX 580 8GB run at 1411/2000 MHz, been kept at stock. During the tests, we took voltage values under maximum load condition and after taking into account, we readied them to show them in charts.
Along with that, we also utilized a gaming benchmark to know little about the power draw during the heavy gameplays. This is for groups who only interested in knowing about power impact on PSU while gaming. The Metro Last Light is one of those games been popular for torturing more GPU and PSU. Note that, it is not GPU only test, the power supply needed to be put on load and in the absence of proper equipment, gaming system has been utilized.
As for equipment and tools, due to lack of funds and correspondence, it is not possible to obtain a high-end testing equipment; those are expensive and out of reach completely. Therefore, the procedure of testing is somewhat limited. I got an EU Power Watts meter to ascertain the wattage being pulled from the wall. In addition, voltage readings taken through locally made but reliable, Digital voltage meter.
In the above tests, the power supply showed power draw of about 75W at IDLE. The ideal load on power supply is 50-60% because an efficiency usually peaks out at mid loads. We move on acquiring the wattage readings. We ran the Prime 95 & Furmark 1.10v Stress simultaneously for extreme load on components. The digital meter showed a high 395W pulled from the wall outlet (AC Input). This wattage is about 56% load on granted 700W, By using plugload verified data, this power supply is about 94% efficient on extreme middle loads. So considering this, the unit with 94% is 371W (DC Output) and that is 53% for ST70F Ti load capacity.
The Metro Last light is one of the heavier game on GPU and PSU. Therefore, we picked that game to ascertain the max power draw during gameplays so we know actual games would take from PSU. We put the benchmark in a 15 runs loop, which actually is a lot. As a result, the maximum power drawn from the wall outlet was 321W which is apparently a 45% load on the power supply. Our testing procedure and available components couldn’t allow to raise up the percentage of load on power supply. The truth is, whatever gaming system gamers own, the usage, whether it is extreme gaming or rendering work, wouldn’t exceed the 50-60% mark. Unless you are running high power GPU SLI/crossfire based system.
We also arranged the test loads on different levels: 20%, 50% and 56%, the typical load scenario for single high-end gaming rigs. The chart is built to provide the wattage drawn at relevant output voltages. We ran the tests to made sure the machine would draw power close to 20%, however, it went slightly up by 4%.
During the wattage test, we also made sure to check the voltages under idle and full LOAD; this helps to understand the power supply’s tolerance level and stability factor. Basically, under the ATX specification, the PSU voltage,
- 5% Fluctuation is acceptable
- 11.4V is least considerable voltage
- 12.6V being an excellent
Voltage regulators should not be more than 5%, for example, on +12v rail product, the max acceptance level would be between 11.4-12.6 Volts. A 12.6V being an excellent and 11.4 being the least acceptable. Anything below from the minimum limit would make the PSU worst.
So looking at the summary, the voltages are merely closed to good. Maintaining at decent 11.93v on +12v rail as a max dip on the voltage cycle is, apparently, seems a good figure especially for PSU stability. It could be alarming if that would have reached at 11.4-11.5v, but current scenario is quite satisfactory. We were definitely expecting something around 12.0V, but even it is not full 12.0V, the resulted 11.93V is nearly a good for PSU stability; well within the specified standards. Overall, under our testing procedure, the voltages are in completely safe zone, so we are good with the unit we supplied and it looks like Titanium unit is quite decent with the added benefit of Titanium (95%) efficiency. In addition, the +5 and +3.3 voltages have been excellent with resulted 5.02V and 3.34V during the course of tests.
Fan speed and Noise
One of the most important feature the new power supplies have got is the Fanless operation during 30-40% load, which SilverStone has implemented in their Platinum lineup as well. However, we did not observe anything like that in their new Titanium Power Supply (ST70F-Ti) yet the power supply has already impressed us with its dead silent operation under the load thrown at it (Load 56% max). During the tests, we tried to hear something by sitting 30 cm away from the testing unit, but there was nothing extra-ordinary to catch; no additional noise has been made in our testing environment. The ST 700W Titanium has resulted in an ultra-low noise unit at mid loads, thanks to manufacturers for using FDB technology.
- Titanium Efficiency
- Smallest PSU integration
- All Japanese Capacitors
- Good Stability
- Fully Modular design
- Extremely quiet PSU
- EPS/ATX 12V enabled
- Solid 5 Years Warranty
- No software support
- No Power ON/OFF Switch
- Price needs to drop a bit
First of all, the build is solid as expected it to be. There is actually nothing wrong on the exterior and with black lead-free paint, the quality and material looks nothing but great. We see similarities in Titanium and Platinum series SilverStone PSU. Not to mention, the similar kind of material design has been witnessed on some of the Corsair high end PSUs, too. The ST 700F Ti confidently serves as SilverStone’s finest PSU in said range for looks and material. The unit carries all the Japanese capacitor inside manufactured by Enhance Electronics. The PSU offers 120mm fan which delivers 18 dBA on noise. Having a depth of 150mm, the unit ensures to fit in every case you like it to be. The world’s smallest power supply unit caters the need to be fit in small to full tower cases. The Strider 700W Titanium is especially very good for PC builders who are looking for fully modular design, which primarily kills any cable mess inside the case and with flat cables, the cable management is tension free.
Coming to the performance, despite our limited testing procedure/methods, we definitely go through whatever we observed through it. We tested the wattage drawn from wall via our gaming system, which resulted in AC input watts of 395W (AC Input) considered to be around 94% efficient with 371W as output watts at 53% load on 700W capacity unit. The ST70F Ti’s power output is absolutely perfect for single GPU high-end gaming rig, additionally, it can accommodate some selective power efficient SLIs/crossfires, too. Stability, on the other end, is monitored via same digital meter, which showed us the power supply has nearly good stability level as part on 12V rail. The 11.93V was the lowest dip we observed, despite greater Titanium unit, the stability is not excellent neither very good, it’s just quite good and well within standards. The +5V and +3.3V stayed on 5.02V and 3.34V as the lowest dip. During the tests, we have also closely monitored the fan noise, and under 60% load, the fan was almost inaudible. Without Fan-less mode feature, this is an excellent output, all credit goes to manufacturer for facilitating it with FDB technology and excellent control on PCB.
A few dislikes/lacking however, came up in Titanium series 700W PSU. it appears that there is no Power switch on back of PSU. Well, we find this quite strange, though it is an exception but definitely limits the functionality plus, in fact that is, one adverse we concluded. We also feel the cable, specifically, the CPU 8/4+4pin (that comes with the PSU) is not comfortably of full length for CPU 8P connector on motherboard, however, that’s one side of story, the good thing is SilverStone packages this PSU with another CPU 8pin connector and that second CPU 8/4+4pin measured at 750mm long unlike the shorter one with 550mm length. It completely secures the deal. A suggestion wouldn’t hurt: Software control/monitoring feature, which would have been a great addition to the Titanium series, like we have seen in competition. So, SilverStone should now focus on adding additional yet advance features into their PSUs for stand out offerings.
Selling at $147 (at the time of this review) on Newegg, the ST 700W with Titanium efficiency offers as much as any other Titanium unit in the market. The company is offering 5 years official warranty for the users having concerns on backup period. Apparently, it’s a solid warranty period, unless you’re looking for 10 years, which is, in my opinion, exaggerated, which you may not find in every brand. Having all the protection features and 100,000 hours MTBF, the unit ensures to deliver the best possible product to the consumer. Offering 696W on a single +12V rail, the unit could accommodate the suitable, power efficient SLI/Crossfire based Gaming rigs without any problem. With Fully modular cable design, users will no longer have cable management hiccups. However, price needs to drop a little simply because it still is a 700W capacity unit. All in all, the SilverStone ST 700W Titanium is good at stability, high efficiency, Ultra-low noise and equipped with modular design for maximum offerings.
Thanks to SilverStone for providing Product sample for this review
