Hello, I have recently purchased Geforce 7950 GX (512MB) Video Card. The manufacture is Evga. They recommend me to use power supply which has folllowing features: "400W or 430W with at least 20amps on the +12v rail" so plz suggest me power supply according to the above requirement, so that i can purchase it from any store. I am waiting for your kind reply. how can i check "20amps on the +12V rail"
Check [link=http://www.hardwareforums.com/power-supply-sticky-5218/]this[/link] thread to get some information on power supplies and also it will tell you about which company make good PSU's. You will find this information written on the PSU's itself....
Off the top of my head any of the following units should be easy to find and do the job: -Enermax EG565P-VE (535W) -Antec TruePower TPII-550 (550W) -OCZ Powerstream 520 (520W) -Tagan TG-480-U22 (480W) Avoid: Aspire, Apevia, Powmax, Q-Tec/Q-Tech/Q-Technology, Raidmax, Ultra V-series or X-connects (the X-Finity's appear to be okay).
