Low power supplies

Name: internet 2007-06-08 13:24 ID:dVL/BNvT

How much is performance going to suffer if i'm using a power supply that's much too low?  I recently upgraded my families PC (Dell, sigh) with a Radeon X1550 (Yeah that's an upgrade on this machine) which is 400w recommended, but this pc only has 220w power supply.

I've noticed when I run games the CPU usage % goes up more than it did before, along with a few other problems.

All over i've heard that Dell power supplies are a bitch to replace, and since tigerdirect is having a big sale on them now it seems like the best time to find out.

Oh, about the pc.  3.1Ghz Pentium 4, 2GB DDR2 RAM, Radeon X1550, 220w power supply, WinXP
