I've never heard of your brand of ps. Should have asked before you ordered. Any system instability? Are you overclocking?

I regret that I did not think of this before...
I´m not overclocking and have no plans to do so.

Check the 12v rail rating in amps on the label. You should have at least 18 amps on each rail. It may have one or two rails. Also, did it feel like it was under 3 lbs in weight? That's also a bad sign of a low end unit.
