MOBO, PS, and Processor, Have I got the power??

[bharn]

I've got the following and am wondering whether or not this would create a power issue. The reason I ask is that when I set the Vre for my processor to 2.3 or 2.4 it jumps to about 2.6 and the 5v 12v AND Vio get too high, 6.2, 13.2, and 3.45 for the 2.4 setting and even higher for the 2.3 setting. It has an ATX connector also, will swithing to that help if I am having a problem.

250W AT power supply
TYAN S1590S MOBO
K62-450
192MB PC100 3 DIMMS
2 HD's, 2CD's, floppy
I740 AGP with 8MB SDRAM
AOpen FM56P PCI modem
I/O Magic PCI soundcard (Vortex 1)
RA300 Radio Card (yes I know but I like the thing!)
ISA I/O card (only using parallel port for printer #2)
USB Enabled with scanner attached (scanner has own power supply)
3" extra case fan
60mm Extra case fan
40mm Fan on graphics card
60mm Fan on Processor

Holy smoke! It's a lot if you write it all down!!!
NO there are no IRQ's left (in case you were wondering!)

250 should handle all that just fine. The worst case is when both HDs and both CDs are running. Assuming about 30W per drive, that still leaves 130W for the rest of the system.
