+12v line too low

[Bodega]

im running a couple 244s on a tyan thunder k8sr with an antec true 550 eps12v power supply and my +12v line is at +11.294. there is no other hardware hooked up yet besides an 80gig drive and a couple fans. is this rail dangerously low, and if so what could be the problem? i dont have any other esp12v ps's, so ive tried running on an enermax 550w with the 20-24 pin and 4-8 pin adapters and got the same voltages.

+3.3 @ 3.403 also

You're getting these readings via software?

those reading are in bios, sorry i left that out

then the bios must be bogus since if ur 12v rails are THAT low..ur computer wont even run

Well, it might run, but would crash constantly at best

Verify the +12 V rail with a DMM.

is having .50 or so more than 12v okay? software on this one shows like 12.40-12.94 usually.

Uh, try reading the posts above.

Get a multimeter.

+12 V rail has 5% tolerance, so 12.60 - 11.40, though you want to stay as far away from those limits as possible.

Only trust a voltmeter/DMM.
