lilack Posted February 1, 2008 Share Posted February 1, 2008 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? Link to comment Share on other sites More sharing options...
Corsair Employees RAM GUY Posted February 2, 2008 Corsair Employees Share Posted February 2, 2008 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.

NickSt Posted February 2, 2008 Share Posted February 2, 2008 The Video card you have requires 22-24 amps on one rail But is it OK that Corsair PSU's have 18A per virtual rail? Link to comment Share on other sites More sharing options...
EliteKiller Posted February 2, 2008 Share Posted February 2, 2008 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. 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. 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 http://techreport.com/articles.x/10779 Link to comment Share on other sites More sharing options...
lilack Posted February 2, 2008 Author Share Posted February 2, 2008 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 but it is only 10 bucks less then 750 so might as well get 750... but wt do u guys think i should do.

EliteKiller Posted February 2, 2008 Share Posted February 2, 2008 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: Link to comment Share on other sites More sharing options...

EliteKiller Posted February 2, 2008 Share Posted February 2, 2008 o THank You very much....750!! here i come.

lilack Posted February 4, 2008 Author Share Posted February 4, 2008 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. Link to comment Share on other sites More sharing options...

Xtreeme Posted February 4, 2008 Share Posted February 4, 2008 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. Link to comment Share on other sites More sharing options...
Corsair Employees RAM GUY Posted February 4, 2008 Corsair Employees Share Posted February 4, 2008 Doesn't sound like you are having a power supply related problem. I would recommend that you test the memory modules individually with http://www.memtest.org to see if you can isolate the problem. Make sure that the memory is set properly in the BIOS as per the manufacturers tested settings! Link to comment Share on other sites More sharing options...
Garvin Posted February 4, 2008 Share Posted February 4, 2008 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. Link to comment Share on other sites More sharing options...
lilack Posted February 5, 2008 Author Share Posted February 5, 2008 heya so..i reformated and stuff then after just reformating and ran the SFC scan thing and zero problems... SO now i can hoping it will work fine. (Crosses fingers) TY again garvin Link to comment Share on other sites More sharing options...
Garvin Posted February 5, 2008 Share Posted February 5, 2008 Hopefully so. Good luck. Link to comment Share on other sites More sharing options...
lilack Posted February 6, 2008 Author Share Posted February 6, 2008 whoa..lame i reformate then i run the SFC to make sure no files are curropted and it still freezes. So i am thinking only thing left is the MB. Guess i go tommorrow and see if i can exchange it. Link to comment Share on other sites More sharing options...
Xtreeme Posted February 6, 2008 Share Posted February 6, 2008 That really maybe best if for no other reason just to be sure. Like I said when a mobo is bad, depending on how its went, can be HARD to troubleshoot. Really, like a cpu only real way is to change it. Good luck, keep us updated.
