Dell Dimension 4600, 450+ Watts power supply recommendation?

[Scottzxc]

The APC battery backup for my Dell Dimension 4600 says I'm using 350 Watts of power. How that's possible when it comes with only a 250 Watt supply, I don't know.

I've added Matrox quad (pci) and dual (agp) video cards to run six LCD's is the reason for the extra power requirement.

Can someone suggest a reasonable quality power supply for this computer?

Thanks
Scott

Duh.... maybe 'cause it was the end of a tough week I didn't consider that my battery backup is supplying power to four LCD's and a subwoofer, in addition to my computer - hence the high power draw. I'll temporarily plug those other items in somewhere else and then see what the power requirement is when only my computer is plugged into the battery backup.

Hopefully the standard Dell 4600 power supply can accomodate a couple of 2D graphics cards, so no need for a bigger PSU.
