I would go with the OCZ because it's cheaper and is rated for 1250w instead of 1000w. The OCZ is only 80+ gold, but that's still a really good efficiency rating. The XFX has an 80+ Platinum rating though so if you're really concerned about power efficiency the XFX will save a little bit more power. I don't have either so I can't tell you about the quality, that's just what I would buy.

I'm just going to say you need at least 3 GPUs to make any of those worthwhile.

With that out the way, are you okay buying from British vendors, or are there any other places you're willing to buy from?

Out of the three, I'd go with the OCZ.

i would propably buy from irish but from british its just very handy as they providing good return service, at the moment im gonna use 2 graphics cards, u see i had previous bad expierence with lower then 1000w supplies, and when i changed to 1000w+ all problems disapears... propably i will go for ocz as they are good brand.

What makes you think you need that size PSU? SLI you'll want a 750...

Well yeah, no kidding your problems disappear. You're using a sledgehammer to crack a nut...A really big sledgehammer.

Obviously I can't say for sure, maybe you were just unlucky, but I'm guessing your bad experiences were more to do with the PSU in question than the capacity. I'd recommend looking into Be Quiet!'s Dark Power Pro P10 PSUs. The 750w and 1000w can be had cheapest at KustomPCs, with the 850w being best bought from Amazon. If you're going with two 680s or 7970s you really don't need more than 850w, anything else and even that would be a waste. I mean, if you're rich then go for whatever, but otherwise it's worth considering.

i have at the moment 750w 80+ but for some reason i cant even set rams to 2133mhz.. mode, had this shit before, as well as for overclocking cpu gpus i will need more power then 750...

Sounds like an issue that's completely unrelated to the power supply to me. Power supplies don't randomly start having issues at high load levels, especially with a decent quality unit. This is especially as with, say an OC'd 3930k and dual HD7970's, the rig would still only be pulling around 600w at most, under extreme load, so you aren't cutting close in terms of wattage in the first place.
