Here's the system:

Asus P4B266
P4 1.6A@2240
512meg PC2100 Crucial DDR
Radeon 8500
HP 9110 8x4x32 CDRW
Phillips 12x8x32 CDRW
2 Maxtor 20gig 7200rpm hard drives
Linksys 10/100 Ethernet
Promise ATA 100 PCI adaptor card
Sound Blaster live 5.1
4 80mm Antec case fans
1 1.44 Floppy

All this is powered by an Antec 300w power supply that is about a year and a half old.All of the 12v molex plugs are being used with one plugged into the Easy Plug for the mother board.At default speeds Motherboard Monitor shows the +12v at 12.04v,as I step up the clock speeds it gets lower.@2240 idle the 12v line drops to 11.49v and when I run Prime95 it falls to 11.12v.Now I don't know too much about voltages but MBM shows the -12v @ 0.56v and the -5v @1.74,I think that looks awful bad to me.Do you guys think it's time for a bigger power supply?


Any help will be appreciated.:cool:

The Antec PP303X does much better with the P4 than the older303 model you are using now. I would consider replacing your power supply with the dual fan Antec PP350X for overclocking...particularly if you want to hit 2.4+GHz.

Those voltage line readings are WAY whacked... i dunno what happened but if it was like that i doubt the system would be running...

I'd get the 400W Antec, it's the PSU I have and I upgraded to it from the one you have, it does a great job... Two thumbs up to a great PSU!

<< Two thumbs up to a great PSU! >>



That's what I thought so I'll order it tomorrow and see what happens!
