Default PSU readings

Yo Yo Yo!

Here are the readings I took today from a new PSU called Zumax X4 750W.
They seem a little high to me but maybe someone can comment? Measurements were taken with a Sperry DM 350A Multimeter.

The first set of numbers is idling and the second set of readings are done under heavy load...3DM06/Memtest/Prime95/Defragmenting HDD's...LOL

FDD : 5.12V / 5.17V
FAN : 5.79V / 5.79V
PCI-E : 12.61V / 12.57V
Sata : 5.14V / 5.14V
CPU-4: 12.61V / 12.58V
3.3V : 3.46V / 3.46V

How long has it been since the DMM was calibrated? Have you confirmed these readings with a bifferent DMM?

That DMM is brand new! The BIOS says different things though....remember the Sensor issue I was talking about?? Here's some pics.





See the 4.08V rating on the CPU? Weird huh?

Recheck with another DMM and don't listen to what the BIOS is telling you since yours seems to be posessed or something.....

There are a few other things which reviewers in general rarely take into account when testing PSUs:

- Try not to take voltage readings from an unused connector.
- Load your test PSU properly (a run-though of 3DMark06 is NOT "load")
- A combination of 3DMark + Orthos + Memtest makes for mutually exclusive load conditions so you will not be putting your PSU under any more load than if you were straight-out running 3DMark

If those are the correct voltages, then that PSU is a massive failure. Period.
