you need to have a lot of power for that equipment you have
A web PS calculator estimates 246 Watts for the setup I described. That leaves 200 watts to spare even if the estimate is off a bit.
The mobo is rated for
140 watts/onboard ATI HD5200/Phenonm X4,
CPU fan, 2 case fans (10w), 120 and 80mm,
1 SATA HDD (30W),
1 Sata DVR/RW (30W),
2X2048MB DDR2 (30W).
either wey a correct functioning 450 Watt supply should be ok, I think.
Am i missing something? I am assuming the 140W mobo includes the CPU.
