How about this PSU? (Moderate Power User)

I am no newbie to computers but power supplies are where it gets rough. I am building for the very first time from the ground up and my specs will be:

+ AMD Athlon II X4 620 (most likely OC to 3.2GHz)
+ Asus 785G Evolution AM3 Motherboard
+ 4GB DDR3 1333 G.Skill Ripjaws
+ ATi Radeon 4670
+ 500GB SATA Drive
+ DVD Drive

So, I need a PSU essentially. I do not fully understand the rails and voltages, and was hoping that someone else might. But, for now, I was thinking that this might be decent:


I am trying to keep this the most economical I think, and $90 is already stretching it, so any suggestions would be great.

  1. This PSU is very high quality and will handle that system fine.
    You dont plan on crossfire do you?
  2. No I do not. I only have one PCI x16 on the board. I wasn't even sure about getting a real card. =P...

    Ah thats right. That was the PSU I wanted from a LONG time ago. Thanks. I'll probably be getting that one. =)
  3. Well, you certainly chosen the most top notch brand you can get so you're off to a very good start.

    Of your 2 choices, the SeaSonic M12II SS-430GM 430W will suffice for your system.

    But, I'll see your Seasonic and raise you a Corsair (only technically as Seasonic also builds the Corsair PSU's).

    Corsair CMPSU-450VX 450W - $49.99 after rebate ($64.99 before rebate)

    Lol, Sonic Boom beat me to it.
  4. Another +1 for the Corsair 450VX.

    Imo, better go 550-650W PSU if you plan to go to a stringer card like a 5850 (550W PSU for this) or if going to CrossFire 2x 5850s (650W for this).
  5. That Corsair looks great. I would get it, but its not modular. Ive never built before, so are the extra cables that much of a nuisance? Would the 430W Modular SeaSonic do me just as good? Or do you really really recommend the Corsair. Thanks.
  6. Well, Seasonic themselves are who make the Corsair PSU's so the quality is the exact same.

    Standard cabling is much easier to handle these days with the bundle wrap sleeves they put on like cables.

    Price and the extra watts were the reason I suggested the Corsair over the 420 watt Seasonic. But either will give you what you need.
  7. Btw op, may wanna change that intel sticker to an AMD, lol.
  8. Alright. They both look good, so I will see. =)

  9. I'm running an almost identical spec using an Antec 380W 80Plus PSU.
