  1. do you have a specific budget? do you want a modular unit? is 80+ efficiency OK or do you want a higher efficiency? otherwise...

    a 500w+ from antec, XFX, corsair, PC Power & Cooling, seasonic, enermax, silverstone, or OCZ

    if you plan to get a second AMD 6950, look for a 700w+
  2. This is a good PSU and it would let you get another GPU for Crossfire. :)
  3. I'm not going to Crossfire nor SLI, so the PSU would power only one video card. Also,I have very low budget, less than 100$. I just want a good working/compatible PSY for my system for a cheap price.
  4. :O now i noticed your motherboard doesnt support Crossfire or SLI, this one should be powerful enough to power your Amd 6950 : for 109$, or this one for 89$ or even this one for 59$ . Amd says a 500w should be powerful enough for that gpu. Sry for all the editing :D
  5. If budget is really tight then this has a 15 dollar rebate right now and should be sufficient for what you want.
    Its always best to get the best power supply you can afford though as its the real heart of the system.

    cougar 850 watter 80+ silver certified 129$ 40 dollars rebate :D, or these 2 other choices, these are ps that will future proof u if u wanna upgrade to a crossfire or sli setup,

    seasonic 850 watt also 80+silver certified

    and also this if ur budget is tight,

    corsair 650 watter ;)
