Hi Noobie here

I recently got into mining and bought 2 x 7950 sapphire gpus as well as a nox psu http://www.nox-xtreme.com/en/product/urano-tx-850w/56/ all brand new.

Only been running the rig for like a week and a half but it kept crashing at 900/1250 settings and yesterday the psu just buckled.

Is this a sign of a crappy psu or was this just a faulty one? and should I exchange it for another NOX or should I get a different brand?

Thanks
