Need new PSU?

[mdg900]

I recently added an ATI HD3870-X2, an extra hard drive, more RAM, and also installed Vista-64.

Since then I've had to reduce the amount that I overclock my CPU from 8x375MHz to 8x353 MHz. Could the power supply be the limiting factor? It shouldn't be the RAM as it's rated at DDR-800. Temperature is fine. The issue I get is freezing in games, random restarting, and blue screen. Seems to happen more frequently when playing games.


Current hardware:

Core2Duo E6400 @ 2.9 GHz
Abit AB9
4 GB RAM
ATI HD3870-X2
3 7200rpm SATA HD
1 IDE HD
1 SATA DVD-RW
X-Mystique Sound card
3 x 120mm fans + 80mm CPU fan
Vista Ultimate 64bit
Hyper Type-R 550W PSU

Thanks, I'll probably buy an ANTEC TruePower Quattro 850-EC 850W.

Anything better value than this? (Cost is £105.)

The Corsair HX620 is great value (~£85) and should run it fine.

But if you want the best, then I think it is cuurently the Enermax MODU82 625W
