sorry i should have made my self a bit clearer lol I meant more do you think that PSU is good or crap! lol My friends have bought a SLI 1KW before but couldnt stand up to crossfireing latest graphic cards and just blew up! (was a crap make me thinks) As its not an OCZ brand or indeed one of the other main PSU brands, wasnt sure if it would be much good

During the past several weeks I wound up reading quite a few competent technical reviews of a OCZ power supplies. When I say competent technical reviews, I mean reviews that actually run proper tests to find out if the psu's can actually operate at the advertised specifications and temperature ratings. They also take apart the power supplies to get a good look at the components. It is safe to say that overall OCZ appears to have taken shortcuts to reduce manufacturing costs. Key features that are standard in high quality psu's were found to be missing. In addition shortcomings were identified during testing. This was particularly true of their 700 watt power supplies.

Corsair and Seasonic are two of the brands that have a reputation for high quality power supplies that consistently earn high marks in technical reviews. They are reliable, stable, and come with a 5 year warranty. Some of the newer models with silver and gold energy efficiency certifications come with a 7 year warranty. Lately we've been seeing a few other brands offering some high quality units.

My best advice woul be to start saving for a new high quality power supply.

+1 to JohnnyLuckys answer. I have a corsair HX1000 Watt and its very good. At 1 point i had 3 4850s running on it. But as Lucky said start saving for a decent quality PSU and do some research on any that you are thinking of purchasing
