Last Friday I ordered a SB 1155 system which I had problems with , the motherboard blew on the second day of use so I returned for a refund.

From my previous thread HERE a few members questioned my psu and to be honest has put me a little on edge, I don't want to order another Sandybridge setup until I'm sure this won't happen again.

As my previous thread I am still running the psu on my Skt 775 system

Q6600 @ 3.7
4gb of DDR2
GTX480

The psu is a Thermaltake Toughpower 850W.

I have installed hardware monitor to check my psu voltages and they are reading good, I will do more testing tonight and run an instance of furmark and prime 95 to check for voltage drop on load, I think I'll try about 4 hours.

If the psu still supplies a competent load can I stop worrying that my psu could be the cause.

Any other tests I could do?

I have borrowed a calibrated multimeter and test leads from work, so will have a go at this in the next couple of days, can you suggest a fairly straight forward guide before I pick a random one of google?

Aslo I will be able to measure voltage but how do I measure the voltage under load?

Admiralhuddy has a excellent guide here.

Sure is, thanks for your time making that guide :)

Here is my results

12v+....off load......load (cpu).......gfx+ cpu load
...........12.16v.......12.16v...........12.21v

5v+.....off load.......load (cpu)......gfx+ cpu load
...........5.07v.........5.08v............5.07v

3v+.....off load.......load (cpu)......gfx+ cpu load
...........3.35v.........3.34v............3.34v

OK managed to do all including 3.3v and all seems fine.

Did you test load voltages and cross-load voltages?

Also, even if all of the voltages seem ok, doesn't mean that the PSU is providing clean power. Switch-mode power supplies do not generate a stable voltage, but rather a wave - the wave is called ripple, and it can reduce the life of your components if the ripple amplitude is high.

The main problem with cheap PSUs, however, is that they tend to damage the other components when they fail (very unlikely in a quality unit).

So in short, no - you haven't proved that it is fine.
