Hello, I'm seaching for a power supply, that make little noise, and can handle:

Phenom 550@3.7 - 3.9 MHz (hopefully with more tha 2 cores :) )
2x HD 5770
3x2gb ddr3 1.65 - 1.72 v
2x 500 gb Samsung F3 in raid 0
4-6 fans
2x DVD RW
1x wintv go
Case: NZXT Gamma

Price: € 50-100;

Brands: Aerocool; Nox; LCPower, BeQuiet; Corsair, OCZ, Tacens, THERMALTAKE

Btw, what is best, 2x 12v with 40-50A in each one, or 5x12v with 20-24A each one?

Hi there,

I would recommend a Corsair 550W. Using this: http://extreme.outervision.com/PSUEngine you can calculate your power consumption pretty accurately. Your PC's is approximately 388W at 90% load.
You always want headroom so go for 450W at the minimum. Better safe than sorry though so get a 550W if you can. Corsair is IMHO the best brand for psu, though there are many other great brands such as antec, etc.

Hope this helps!

well i wouldnt do a 500w psu for dual 5770s, multiple drives, etc. ok i would say the corsair 650w would be sufficient. its still a great psu!

The more watts the better but its of course more expensive. Get the most you are willing to spend! That link I indicated simply helps you select the cheapest option. I can tell you with confidence that a 650W would be more than enough; I am running multiple drives, 5 fans, an overclocked 955 and a 5970 on a Corsair 650W and I've had no problems at all.

Good luck!

not in the price range

Corsair 650TX. With the Japanese caps it comes with, 30% capacitor aging would likely take a good 10+ years.
