anyone has try: K8N Neo2 with a PSU Cooler master 450W real power?

[phuzer]

Hi i bought a Cooler master 450w RS-450 ACLY real power (2 rails 12v & PFC).

http://www.newegg.com/app/viewproductdesc.asp?description=17-171-001&DEPA=0

I think will arrive at the next week

I bought because all the reviews in the net given great score and looks quiet.

But all reviews has in system intel P4 prescot because drain much more power than a Winchester. In all the reviews the PSU has great performance and stable 12v lines. Also have good features like Active PFC, efficiency > 75%, ATX12V V2.0, 12cms fan, analog display and say be QUIET!

Now i have a weak 350w PSU with 15A 12v, and the MSI CORECENTER read between 11.3 - 11.4 volts at 12v rail (maybe corecenter was wrong with the voltage).

This is my system:

A64 3000+ 939
MB K8N NEO2 Platiunum (bios 1.41mod)
1 GB ram 2 x 512 Gskill.
GF4 MX440 but soon GF 6800 (BFG)
1 SATA samsung HD
CASE TT Tsunami
4 FAN. (2x 120mm, 1x 92mm, 1x 80mm)

This PS its enought for my system? I think yes. But with the problems that I have read....

Any recommendation before using a PSU with this Mobo?

Thanks

PD: Sorry for my english.
