More about watts this
  1. A good 350 watt PSU would do, but I would prefer atleast a 430watt.
    Fortron makes a good PSU.
  2. so how does a 450 watt do just incase i wanna upgrade like upgrade the cpu to a athlon 3700+ and get 2 x Geforce 7800GT instead of 1
  3. Bigger won't hurt, just make sure it is a brand like Fortron, Antec TruePower, PC Power and Cooling, etc.
    A 450 watt should run $70 and up, much less and it starts getting questionable.
  4. could u look on www.newegg.com and find me a good psu with 450 watts or 500watts with a price through 40$ 70$
  5. oh wait how is ultra psu they look cheap and good
  6. NewEgg is not working for me right now for some reason, but I just bought This 550 watt from NewEgg for $89 and am very pleased.
  7. the site went down now its back up
  8. Yes that is the one I got exactly.
  9. It runs quiet and cool, and has plenty of spare wattage, and is built to last.
    I was running an Antec TruePower 430watt before that for 2.5 years, and now I am upgrading mobo and CPU, so the 430 will live again in spare build.
  10. I'd go for 420-480 watt.
    Check out new Liberty line from Enermax.
  11. Enermax rocks. I've got a 485W PSU on this configuration:

    2x 7800GTX's Factory OC'd (SLI)
    1x Athlon x2 4200
    2x WD Raptors
    2x DVD/CD burners
    4x 256MB DDR400 DIMMs
    3x 120mm case fans
    1x ASUS A8N-SLI Premium
    3x USB devices (hard drive, camera, mouse)

    nVidia says you need a 500W PSU for that. Pffft. My 485W is rock solid... although it did flip a breaker the other night. But i also had 2x 1500W electric heaters on the same circuit. LOL. Won't do that again.

  12. You should go for a 400 watt power supply from PC power and cooling. Sure they are more expensive than others but the efficiency and quality of their products is top notch. Their 400 watter equals a 500 watt generic.

    THese are all WAY overkill for your choice.....these are 535-550W ALl great brands.

    you would have t actually TRY ot build a machine that used more then this....like 15HDD's with your 27800GTX's and FX60(dual core FX line comming soon) and all PCI slots filled and all USB ports powering something.

    550W is SUPER BEAST!
  16. could that first 450 watt power supply run this
    Athlon 3700+
    Seagate SataHardrive 80 GB
    CorSair 2 Gb of ram (4 x 512mb)
    2 x Geforce 7800GT SLI
    ASUS A8N-SLI Socket 939 NVIDIA nForce4 SLI ATX AMD Motherboard
    Dvd Rom Drive
    Cd Rom Drive
    Floppy Drive
  17. This brand of PSU sucks. I know because I worked with them before. had 10 units and 40 percent failed in less than six months. I gotta give it to them though, they replaced said units. The experience is downright awful though.
