[Buying Guide] Power Supply [UPDATED OCTOBER 2011]

Power supply thread

From A long time I was thinking of creating a power supply thread in which members can discuss their power supply queries, graphics card power requirements and total system power supply estimate .I will also update the thread with the availability of new hardware. If you are confused in selecting the right power supply for you just tell your pc specs here or just send me a pm and I will suggest you a good power supply according to your budget.
I m starting from graphics card general power requirements so:

THE GRAPHICS CARD POWER REQUIREMENTS

Keep one thing in mind that the entire list is based on PCI-EX graphics cards

Spoiler: show

I search on many website for the power requirements of the graphics cards and so far this list is accurate and correct and I gave the whole list in simple text format so you can easily check it out even with a slow internet connection and it’s also easy for me to update this type of chart

in the above list I search for all the cards and give a general graph of their power requirements and how much amperes they consume as graphics card use the +12v rail

Now I m moving towards the processors and their power requirements and I m only write on Intel CPU because mostly peoples in Pakistan use Intel

POWER REQUIREMENTS FOR PROCESSORS

Processor name

Spoiler: show

Old processor used the 5v rails of the power supply but as power demands increased, the high currents required to supply sufficient power became problematic. With the introduction of the Pentium 4 microprocessor, Intel changed the processor power supply to operate on +12 V and added a separate connector ATX12V to new power supply same thing is used in graphics card so for both things we have to check the +!2v rails on the power supply
You can see that all the dual core and core2duo’s are using same amount of power but latest processors use power then these processors and while checking the requirements of a pc power you have to check the power consumption of processor and graphics card and leave the other components because they don’t use much power
The power requirements of all the other components can be determine as:

• A power supply its self consume a power of 5 – 15watts
• A cooler consume as low as 1watt power (excluding fan)
• A motherboard consume 8 – 20 watt of power
• A hard disk consume a power of 4 – 8 watts
• A ram consume 6watt of power
• A case fan can consume 1-10 watt
so you can see that all the other components of pc does not need much power the total power consumption of these items will not more then 50watt means they only consume a power of 4-5a most of the components use +3v rails and 5v rails but as the +12v rails is major and most important voltage of the power supply so we always check +12v rating on the power supply before buying.

FOR GRAPHICS CARD’S WITHOUT EXTERNAL POWER CONNECTOR:
In simple words some graphics cards don’t have external power connector they consume less then 65watt power
So If you have a graphics card which does not have a external power connector and you are using a normal dual core pc then don’t worry about any thing and install the graphic card in the system because at least all power supplies have minimum 10a on 12v rails and they can run a graphics card which needs 50-60watt or 5-6a some low ends and mid end gaming cards don’t have external power connector such that 5670 and 4670 these cards consume low power then 65watt and they can easily run on any bulk power supply

FOR OVERCLOCKERS

Over clocker always worry about their power supply requirements and their consumption so if you are over clocker then on a save hand it is better to get a branded power supplies because non-branded power supplies don’t have good efficiency and they does not give better results and if your pc needs 20a then it is better for you to get a power supply which have more then 25a so you can easily over clock processor without any problem

And now I think its time to move on into the power supplies discussion so in Pakistan we have 5 different brands of power supplies available, these are; CORSAIR, XIGMATEK, SILVER STONE, COOLER MASTER and ANTEC.

After a long work I collect the different power supplies specs, there voltage ratings and output power and many more about these power supplies and gave you general type of chart on power supplies and also mentioned power supplies with there supported graphics cards so we are starting from the corsair :-

CORSAIR

Spoiler: show

ANTEC

Spoiler: show

XIGMATEK

Spoiler: show

COOLER MASTER

Spoiler: show

SILVERSTONE

Spoiler: show

Silver stone power supplies are nice performance power supplies after the corsair and xigmatek and in some cases it perform better then these two because its 500watt power supply is a modular power supply and prices Is also low so if corsair or xigmatek is not available then this should be your next choice

SILVER STONE 500watt

Spoiler: show

SILVER STONE 850watt

Spoiler: show

Now I gave you a general chart on the power supplies specs their supported cards
And the entire list is based upon more then enough principle and I overestimated all the cards specs and while buying a power supply it is better to choose a power supply that have more then enough power to run the cards and this list is totally base on this
For example a corsair 400watt can run gtx285 in some cases but I didn’t write it because if you over clock the processor or installing a hardware that consume extra power then its better for you to Get a good power supply for this

NOTE: NOW as we have so many new power supplies from different companies like corsair, antec, xigmatek, cooler master, thermal take, XFX, Silverstone, and many others and it is now too much difficult for me to get the full specification of every power supply and mention its supported cards here because this industry is expanding day by day so from now on I will only mention the power consumptions of different products like processor and graphics card and you have to do the other work yourself. Always check the +12v rating before purchase the power supply as I mention above. Or ask for it in this thread or make a new thread but always mention the Number of Amperes on +12v rails in order to get the required information from us.

awesome man..... very good work....
mods should make it sticky.,,,,

**kamii** · 19-06-10, 03:05 PM

great work... very much helpful! This must be made sticky!

**HMS1193** · 19-06-10, 03:12 PM

Damn good sunny..... This will be really helpful as a many guys are a bit confused about the PSU requirements for their GPU and PC's..

**XaeeM** · 19-06-10, 03:23 PM

thats it mann!!! u did the the valuable work!!

**iameXtreme** · 19-06-10, 03:28 PM

thats an amazing work. the amount of effort you have put in this is just amazing. this should definitely be stickied

**Waris Arsh** · 19-06-10, 06:13 PM

very good effort

**kamii** · 20-06-10, 02:23 PM

I have a question.... how much should an Asus 400W PSU with 21A cost, which is merely 10 days used?

**sunny945** · 20-06-10, 02:55 PM

^ about 1.5k-2k this psu can run card upto gts250

**LiV3 WiR3** · 20-06-10, 03:41 PM

Very Good Work Brother.Very Good!!!
Here Burn the Old Guide by Opethian OR mix this One with That one PLUS the GPU buying Guide by Daizy........and Sticky this Mixture!!!..:P
ADD CM Real Power Pro 80+ NOW!!!!....

PLUS make a guide on my CM 1.5 MegaWatt PSU!!!..:P
and do not Dare to compete with my PSU.....It has got 99999989780998769869879a!!!!.....

.......Suck On that!!!....
