Which powersupply


lilack

Recommended Posts

So i have a IP35pro running 2gb corsairs ram and a video card EVGA 7950GT.

i have a 600watt now and was told that it was not enough because the 600 only gives 12v and my video card needs about 20 or 27 for SLi i was wondering how do i check it if it has more then 20? and wt wattage would i need to get. I was thinking of a the corsair one the TX750 i think that was wt it was called. or would a HX620 be enough?

The Video card you have requires 22-24 amps on one rail, I would suggest contacting the make rof the Viode card or the maker of your PSU and ask them if its compatible if not then I would suggest our HX520W or TX550W for that system configuration.

lilack, a Corsair VX450 would run your system without breaking a sweat, and it would also handle SLI'd 7950GT's. If you want more power for future expansion then purchase a higher wattage Corsair psu that fits your budget. We'd need the brand and model of your current psu to answer specific questions about it.

Just to clarify for lilack, the graphics mfg. recommends 22-24A (264-288W) for the entire computer system.

 

The 7950GT is a low power consumption card and cannot draw more than 150W (12.5A) since it only has a single PCIe connector. I think you'd be hard pressed to have one pull over 100W under a full gaming load.

 

Nvidia rates the 7950 GT's power consumption at 82W

ok so here is my PSU

 

Model ULT-V600DR

AC Input voltage: 115/230v

AC Input Frequence: 50-60Hz

AC Input Current: 10A(RMS) FOR 115 VAC input

6A (RMS) FOR 230 VAC input

 

Max Output +5v +3.3V +12V1 +12V2 -12V +5VSB

................30A.....25A....18A....20A.. 0.6A. 2.5A

 

 

So its MAx watt of 600watts.

So thats my PSU... if i have to change it i was thinking of getting

Corsair CMPSU-750TX 750W High Performance and Energy Efficient Power Supply

http://shop3.outpost.com/product/5443359?site=sr:SEARCH:MAIN_RSLT_PG

 

So that i can use it when i get a second evga 7950GT KO

 

Or would that be to much power??? TY for help guys

 

 

or should i just get the

 

Corsair CMPSU-620HX 620W Modular Power Supply

http://shop3.outpost.com/product/5278297?site=sr:SEARCH:MAIN_RSLT_PG

The Ultra V-Series are low quality psu's. The max combined watts on the 12V rails are 420W (35A). For reference the Corsair VX450 has a single 12V rail rated for 396W (33A), and the VX550 offers 492W (41A).

 

Ultra V-Series Cons

- Horrible voltage regulation under load

- 12V ripple exceeds ATX spec under heavy load

- Efficiency is terrible

 

While your current Ultra psu will power SLI'd 7950GT's, the cons above are prime examples of why you should switch to a quality psu. If you don't have a need for modular cables, and you can afford the TX750, then by all means go for Corsair's big boy. :D:

ah!!! ELITEKILLER!!!!! after one day it froze again!!! I got the TX750 and used my comp for a full whole day yesterday without it freezing then i leave it on today and come home and find that it froze. Only thing left is the MB. Is there no way i can test the MB with a program or something. I know i did buy the IP35 Pro in a open box at fries. Should i try and go exchange the motherboard for another one of the same kind? or is there a different solution.

Mobos arent easy to test without just changing it. They can make things a nightmare I can tell you that. As the lockups, bsods or otherwise can seem to be without reason. Random freezes you name it. Best bet since it was open box is to return it. I never buy open box electronics for that reason. It was returned for a reason, possible they had same problem and frys just stuck it back on the shelf.

 

I would keep the psu though, as a good quality psu is KEY to a stable system. A bad psu can kill your other parts also.

Lilak had already pm me on advice for the psu off the Fry's site. He sent another pm about a game stuttering problem, that he suspected was due to overheating, but with the aftermarket cooler he has I doubted it, so I made a few suggestions. When he ran sfc /scannow at the Run box, turns out all that crashing with the inadequate supply has corrupted alot of core Windows files.
