ups advice and a few minor issues

[bdax]

1:I have a 620watt psu and a aurora ups 2000kv (1000watt) ups it runs my pc fine the issue is that i want to upgrade my system and get a say 750watt psu or a 850watt psu will my ups be able to handle the psu? because there are other fans and lights on that ups as well
2:i would like someone to tell me how do i calculate the ammount of power draw for my psu from the mains
3:the pc im upgrading to is i52500k sabertooth mobo some high end pc case i have 4 sata drives and a gtx 580 so will the 620watt psu be enough or shud i change it to a better one ?
4:i have mixed reviews for the antec cp 850 any one who has had it or knows any one who has had it please comment on its quality etc

best regards

At first look it looks it will be enough but need answers to the following:
1- How many fan/lights (watts) are on it ?
2-What is the model no. of the 620W psu ?
3- What lcd size are you running ?

 

[bdax]

1:i have like 4 fans and 4 lights on it .
2:its cooler master real power pro 620watt
3:its a 27in

1- With those it would be around 480W for those appliances
2- GTX 580 itself is 280W card when gaming on peak. Your PSU is bare minimum to run the system and I would not recommend running it at all. Minimum recommended PSU is 42Amps on +12v, your PSU delivers 43 Amps over 3 rails.
3- 27inch would be itself consuming around 80W if I'm correct, as 24" lcd consumes 60W.

Advice:
You can change the PSU to single rail+12v with atleast 50 Amps on it. Secondly, you also mustn't run ALL those appliances when gaming. Atmost 1 fan and 1 light when gaming. On idle it's power requirement would decrease significantly and then those can be run.
Your UPS will handle even an 850W PSU but again limit fan and light as mentioned above. This is only my analysis. Others can correct me if I'm mistaken. Ali Tayyab will be knowing better.

thankyou and any idea about the cp 850 ? psu or which one should i get ?>

 

[kingsface]

Though CP850W is a good supply I would rather recommend Xigmatek 800W from IMX. The cp850W has multiple +12v rails whereas Xigmatek has a single +12v rail with 64Amps sufficient for your needs. Also Xigmatek 800W psu is 80 plus Bronze certified whereas CP850W is only 80Plus. Both are modular supplies reducing your wire clutter. The difference in cost is only Rs.1500 and so Xigmatek 800W is the better buy imo.

Here is the link:
Xigmatek 800W

They deliver Pan Pakistan and is 100 percent trusted.

Well johnny guru is pretty strict in rating but others can suggest alternatives. Also depends upon your budget for the psu.

 

[bdax]

budget is not really an issue .i just want a good ups that wont fry my ups i think a corsair 750 will do.but the reviews etc suggest that the cp 850 is a very stable and a must buy if you are buying a df 85 or any of the cases that support it

well i have a heavy gaming rig -- installed a dedicated ups for my room --- 2kv original homage with2 - 200amp battery standby time = more then 5 hours .

thing is depends on load --- i dont want the pc to trip i have 2000watt psu m, but in gaming sessions it does trip coz there is a delay in the ups switch over .

anyway againa lot of factors m depemnds on this ..

the ups cant take the load of the rig if i want to game again ...in the sence the power draw exceeds the ups capacity of 2kva .

i have a 1500wat tt also .it does not allow the system to trip out but again if i game ,,ups wont take the load of the rig alone ..lollllllllllll



u need a 2 kva ups would be enough for you and 4 rooms as well --- more then ample power there ....

 

[bdax]

exactly ! same thing here if im gaming etc when the light goes out the little power savers start to fluctuate so i have to quit the game but it stays perfectly fine on normal browsing or light games like dota etc .
so here is the question
1:if i get a say 750watt corsair tx or ax psu or antec tp700 or a cp 850 will that fry the ups if im gaming ? even if i quit the game after a save like i do now and will it be fine on normal load ?
2LEASE FIND ME SOMEONE WHO HAS USED A cp 850 i really want that psu but i cant find any good reviews except a few on jonnyguru and one more i forgot the site

dont go for p67 sabetooth get a z68-gd65 instead for better overclocking....i cant say anything about ups ....i use generator of 3kv and its very good

 

[bdax]

link me a shop whos selling that .

nvm googled it astron is selling it

system restart is usually because of the switching time, homage-mercury ups have time of around 40ms whereas sinwave ups that are designed specially for PC have time of around 2-4ms, i have a mercury 2000kva ups my system is a 2.6 c2d with gts-275 silverstone 500Watts and a huge 21inch IBM CRT .. and it does trip/restart it even normally .. but after that it runs perfect even though we have around 3-4 fans and 7-8 savers .. still i am satisfied as it never failed me in past 2 years

i have also heard that local ups makers have made a ic kit for PC,s and dosnt trip the system but havnt seen such ups in action .. get a sin wave if you want to avoid restarts but mind that those are expensive else with generators .. well it has its own issues

Holdup time (the amount of time that a PSU can keep running the system by using the energy stored in it's capacitors in the event of power failure) of PSU is usually 16ms. Now in order to avoid restarting the PC when electricity gets cut off by WAPDA you need a UPS that has the switch over time (time in which UPS has successfully transferred connected devices to it's battery backup after mains power failure) lower than PSU's holdup time. Homeage UPS and other inverters with external/liquid batteries have switch over time of 20ms+. PC will get restarted and esp when PSU is busy in handling gaming load that holdup time is a bit shorter than idle holdup time.

No need to get 2000 watts PSU and put it on 2kva UPS/inverter which translates to around 1200watt typically. Put any PSU that can take the load of your PC easily (600-700w is sufficient for any overclocked high end system with single VGA card configuration). And put an online UPS with internal dry cell batteries that exceeds your PSU capacity in terms of wattage and are lower than your main UPS/inverter with external batteries in between your main UPS and PC. e.g your PC is connected to smaller UPS that is connected to main UPS so that it will cover that 12-20ms time when main electricity goes off.

But check it before buying as some UPS don't like the square wave input of homeage or other inverters and use their battery backup and trip after few minutes.

@maz9009 bro that will be very expensive setup, mercury/homage 2000kvs(1200watts) ups=14000. 2x150amp=20000 that is toooo much cost man. and a second online ups that is roughly 1000kva(600watts) with dry battery is not les then 15000 itself.
