Power Supply Requirements for this rig

[Bradtechonline]

Biostar Tforce 550SE

AMD Athlon X2 6400+

Radeon HD 3870 512 MB

4 GB G.SKILL PC2 6400 5-5-5-15

WD 320GB Caviar RE SATA

Samsung DVD Burner

Floppy Drive


600 Watt OCZ Sound about right for it?

I'd guess off the top of my head it will pull around 400-500 under load.

I'm guessing it will pull no more then 200-250w under load, and that's a pretty educated guess,. I'd rather buy this: http://www.buy.com/retail/sear...e&display=col&dclksa=1

55$ after google checkout, free shipping. This usually goes in Power Supplied btw. And, in the end, any decent 400-500w will be good enough. But you'll have a hard time finding a better qaulity unit then the corsair 550vx for less then 55$, so I wouldn't even bother. If you are really concerned about wattage and/or future upgradibility then you could always get this: http://www.zipzoomfly.com/jsp/...p?ProductCode=10006237

Power supply requirements are way, way overestimated these days. The people who go out and buy 1.2kW PSUs can only be plugging a kettle in and having it boil water for their tea because there are some insanely overpowered PSUs and no need for them. As Marc said, it'll not hit 300W so anything reliable around 400-500 is well enough.

The only way you're going to max out a PSU lower than 450 watts is with two big dual video cards and lots of components and drives. It's pretty funny how people have gotten carried away with wattage requirements. I see people recommending 600-800 watt PSUs for single disk, single card systems under some strange assumption that modern PCs are power hungry. Any research proves that a modern system with power management features consumes a LOT less power than machines from a few years ago. And a few years ago, a 300W PSU was standard and it wasn't uncommon to see 200 to 250W psus in even power hungry p4 boxes.
