  2. Okay, thanks. I also forgot to mention that I will be running 2 extra 120mm LED fans, and a ASUS DRW-24B1ST DVD burner.

    I was looking at this PSU:

    Would that work, or will 430 not be enough? Im on a pretty tight budget, and that fits right in at only 25 bucks after rebate.

    U can't beat that price : )
  4. This will do fine, with room to breath.

    How does $69.99 at Newegg sound to you? There are an awful lot of units at Newegg around this price point. Not many of them are likely to equal this unit's performance, though.

    it will work even if add six more 120mm fans. you won't break 300w gaming with your set up

    Hmmmmm, idk, in my motherboard manual says it recommends at least a 450w PSU. I'm not sure if that's just ASUS covering their behinds, or if there is some truth behind that...

    not all PSU are built with the same quality and there is no regulation on what you can put on a PSU. so i can take a 300w PSU and stick a 450w sticker on it and sell it as such. asus needs to recommend for bottom of the barrel PSU, the corsair you selected offers solid performance for a budget unit.

    with the AMD 7770, the following unit did not break 250w total power under a stress test

    Core i7 Test System Specs
    - Intel Core i7-3960X Extreme Edition (3.30GHz)
    - x4 2GB G.Skill DDR3-1600(CAS 8-8-8-20)
    - Gigabyte G1.Assassin2 (Intel X79)
  8. Hmmmmm, okay. That makes sense now.

    Just one last question. Will a 430w PSU still work if I put in a radeon 6850 instead of the 7770? I think I may have one of those in my future down the line.
  9. yes, bit-tech used it in their basic PC set up for a GTX460 1GB and it uses more power then the AMD 6850 (uses about the same power as the 768mb version of the GTX 460)

  10. Okay, it looks like I'm set then! Thanks for all the help, I really appreciate it.
