Try using the big power connector on the mobo and the little square one... Some persons on an amd setup got way better 12v readings then just using the big one alone. Give it a shot(if not done already)

TTGI 450 Watts - This guy actually is dead on in 12/3.3/5 volt rails using Multi-meter while system is running. Yet, the mother board circuit is under load, where Windows and BIOS both report lower voltage:

Multi-meter (hook up under windows) vs MBM/Windows/BIOS

12.15 vs 11.67
3.31 vs 3.18
5.19 vs 4.89

I put this PSU to another system

12.15 vs 12.24
3.31 vs 3.4
5.19 vs 5.20

I do have another PSU 500 Watts that is so bad; shooting it is my only way to express my gratitude to the maker.

Sorry to say, the only PSUs I will spend money on without being screwed first are;

OCZ
PCcooling
Cooler Master

May be with ?
Antec
Thermaltake

As for motherboard; I will check the voltage via BIOS using a known good PSU; without a second thought I will RMA the sucker if the voltage is on the low side. This way, I don't waste my time.

so that's a lot of different approaches.
first approach for me : not spending any more money (vapo/fx53-asus xt-pe, 1 gig of ram, a (now dead raptor) two maxtors in
1and a 1/2 month is a bit over the edge I think.

the fact is.
it didn't crash under load or sth (prime), it crashed randomly.

the fact is also that this psu was doing an 80w pelt, a 9800xt, 3 hdd, lots of fans and a friggin 4 ghz p4, never rebooting once, putting it in a fx53 default without any peripherals unoverclocked with no pelt should NOT give this problem, giving perfect rails on anything I threw at it beforehand 12 flat and 5 flat.

ah
pcs suck :)

if the problem persists then, it's hammertime.

fact is that the network also fell out tens of times on this mobo...
isn't that where the problem lies then?

fact or no facts 11.20v is too low...

what (directly available) psu would you advise for me?
antec?
ocz?

Or, the motherboard is giving low voltage.

My preference is OCZ; reason = they have to service the hell out of new customers.

if the problem persists, both the reboots and the lan-problems, wouldn't the smarter choice not be to rma the motherboard?
because the psu has served me well and shown its worth in the past, the mobo has NOT. and the marvell-lan problems have been described... maybe switching it with an msi would solve the problems...

I will have no second thought.;)

listen...
I was planning to get me an antec truecontrol 550 anyway, so I did.
I will recheck this setup next weekend with the antec, do a complete reinstall with all drivers, and I will advise all present hardware to do their job.
If it still doesn't work I will rma the motherboard.

does anybody know what is safe voltage for a hypercooled fx-53 processor?
and what is that Vfid voltage?

btw, since mbm is dead, what programs are you guys using nowadays for cputemp?
