Can my 400 W PSU handle with HD 6770.

So, i want to buy a new gfx card. It is XFX HD 6770 1GB. I wanted to see can my PSU (FSP 400-60APN 80+400 W, Active PFC) handle with this gfx card without any problems.

  1. With ease.
  2. 450 Watt or greater power supply with one 75W 6-pin PCI Express® power connectors recommended (600 Watt and two 6-pin connectors for AMD CrossFireX™ technology in dual mode).

    So i don't think it will run it. (At least without problems)
  3. He has 2 12v rails at 17amp max or total of 28 amp combined. he will be fine.

    Yeah Snowcrush I agree with you but my PSU is not everyday (If you know what I want to say) PSU, it's 80+ certified, so... definitely it should handle it but, do you think will there be any problems (I want your personal, not theoretical opinion)
  5. I don't really know, because i got a 750W 80+ certified PSU, and sometimes i need to click twice to run the computer (With a gtx470 OC) Even that the 470 needs like 400 W maximum, No idea though, don't just go buy, test it, if doesn't work, go buy new one.


    P.S Im ordering a I5 2500K right now ^_^
  6. What i love about these 80+ Certified ones though that they look cool and easy to manage, and has a lot of connectors ^_^
  7. The 6770 is a relatively low power card, that 400W will be fine unless you have other power-hungry components or are OCing.
