Only way to tell is via a Multimeter.

I wouldn't trust the software measure in the least bit.

Set the multimeter to read DC voltage, set the ground in the black motherboard connector, and the other lead into any of the orange connectors.

Then turn on the PSU by placing a piece of wire from the black connector, to the green connector (both of these on the PSU).

Why does it have to be 750w? You can use a 500w unit for your rig...

Just get an RMA with thermaltake going and they'll send you a new unit. Corsair doesn't have a 750w modular PSU. You'd have to go up to 1000w unless you could make due with 620w.

Ximgatek 750watt Modular/80plus The only other name brand PSU out their in the 80plus/750watt/modular category that I would trust.

I've looked at the Zalaman but I've never done any research to know how good it is.

The Xigmatek 750 is still unproven. The 850W version showed some QC and performance issues. Until we get a review of the 750W from someone reliable, it's hard to give it a pass.

The Zalman is based on the FSP Epsilon. Since it is over 600W we have to worry about ripple. Thankfully, Zalman has worked with FSP and eliminated the ripple problems in their 750W version: http://www.hardwaresecrets.com/article/661. Unfortunately it is on the expensive side considering it is just a decent, group regulated design. Even though the Xigmatek is unproven I would probably choose it over the Zalman since it is much cheaper ATM.

The Silverstone ST75F and DA750 are also options, the DA750 being the better of the two.

Yes, please test with a multimeter before RMA'ing. I would test all your connectors/voltages while you're at it.

If the PSU is shutting down, then RMA it. By my own experience, it's an anomaly - I've heard good things about TT PSUs, and indeed I have one powering my own build, it's been doing so for two years on a 24x7 basis.

It might be worth investing in a PSU tester - you plug the PSU leads into it and it gives you the voltage readouts. They're cheap enough, but if you already have a multimeter lying about, use that.

Hi guys guy tested it at computer shop can confirm its faulty! RMA it today vans coming to pick it up, hopefully the replacement is up to scratch otherwise changing make. Thanks for all your help hopefully no damage has been done to components.

System down actually gave me time to fit my new scythe 5.25 cooler and tidy to improve airflow!.

mosy psu testers do not read newer psu's correctly, most psu detecters fail a psu if it does not have a -12v line, newer psu's do not have a -12v line, so they fail

how were you originally reading voltages? speedfan is almost always wrong, hwmonitor is sometimes right
others base from the same results
bios is the closest to right thing software wise you can read form
