Can the OCZ 600W stealthxstream 2 run a GTX580?

I think it can run it,see this review and you will understand.Also if you see your psu sticker it says how many 12+ volt rails has and how much Amps they have,this is a 4rail with 18A to every rail so 62A on the 12v.

The OCZ StealthXStream 2 Series OCZ600SXS2 power supply unit claims a combined +12 Volt rail continuous current rating of 50 Amps. Hardware Secrets test review seems to confirm this during their Overload Tests where they were able to draw a maximum of 52 Amps from the combined +12 Volt rails.

It will have no problem powering your system with a single Palit 3GB GeForce GTX 580 graphics card.

You could do it, but I can't reccommend it anymore. A few days ago I had the 700W version of that PSU blow up on me only after a year of use.  

Are you getting it replaced under warranty?

one probably, if you plan on getting more I would say get a 1000w or at least a 850

No, I'm not going to put my computer and home at risk of a fire again (yes, there was fire and smoke). So, I got a Corsair unit.

^so your one of those people who will not touch a product from 1 bad experience. i tell you this, im sure there are corsair units that have gone up in puffs of smoke too..... and do you even know the cause? it could have been a power spike, build up of dust, dirty power going in.........get the idea? If there was a major fault with these units they would recall them.

Other people on Newegg have stated that they had the same thing happen with the PSU. With mine the fan failed so it overheated. And I'm sure Corsair units have blown up too, but I haven't seen it all that much, or they are usually just DOA. Anyways, this is going off topic. Yes, the OP can run a GTX 580 with that power supply, but I'm just stating what recently happened with mine from the same family.

Thank you sir, just what I wanted to know  

I honestly wouldnt recommend it. A good 700-750 would be fine though.

I may aswell give it a try, Im planning on using it in SLI in a new build anyway   I can always buy a new supply if it comes to it.

Just to be a messerschmit - 4x18 is 72 but since 600w is the max, you can get no more than 50A of 12v.
