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.
