how many watts do i need to run this computer:
Athlon 64 3200+ 939 Socket
Geforce 7800GT 256 Mb pci express x16
Cosair 1 Gb (2 x 512 mb sticks) PC 3200
80 Gb Sata HardDrive
ASUS A8N-SLI Socket 939 NVIDIA nForce4 SLI ATX AMD Motherboard
 
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
 
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.
 
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.
 
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.

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!
 
could that first 450 watt power supply run this

Seagate SataHardrive 80 GB
CorSair 2 Gb of ram (4 x 512mb)

ASUS A8N-SLI Socket 939 NVIDIA nForce4 SLI ATX AMD Motherboard
Dvd Rom Drive
Cd Rom Drive

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.
