Is my Corsair psu faulty?

Garyj881 · 10 Jun 2009 at 13:07

While stress testing with OCCT I cam accorss my psu voltage on the 12v rail and it's reading 7.25v :eek:

I realise that the software programs don't allways read true, can some one try OCCT if possible and see what reading you get?

I am not experiencing any issues with my rig at the moment.

Heres a pic

Downoad Everest or HWmonitor and see what readings you get from them - or just read them from the BIOS monitoring screen.

These should give you far more reliable readings.

It's fine. If your 12v line was really at 7.25v then your PC wouldn't be working.

Buy a multimeter, it's no way below 9v...

but as said above If your 12v rail was at 7.25v your PC wouldn't be working...

try another software like EVEREST Ultimate Edition or go in to the bios.

most programs read it wrong on some motherboards. the bios gives the best reading.

Just tried Everest and it's reading 11.97v, happy with that.

I thought that aswell, was fairly confident it was wrong so I did try speed fan aswell but that was giving worse readings.

With Everest reading 11.97v I won't bother but yeah I aggree a calibrated mulitmeter is the only definate way to get an accurate reading.

As mentioned the system does run great and don't get many issues.

Forgot about the bios,good call.

I learnt my lesson years ago trusting software to give accuarate results!

A friend at work was having issues with a cheap amd rig, I told him to check the psu (cheap crap of the bay) he went with speed fan and was reading around 9v, he then bought a new psu (cheap crap again) and was reading the same voltage.

Maybe a good idea for power supplies to come with a volt meter.

Thanks

BIOS isn't always that true either.. Nothing like using a multimeter:

A cheap digital multimeter isn't likely to be much more acurate than the mobo(Unless the mobo is faulty) They have an error range of up to 1%. So don't go out and buy one just for this

Even the mid range multimeters (Price range of £130-£250) will have a basic accuracy of 0.3%. Callibration can improve that, if they allow it.
