I'd recommend the Corsair 850AX. Nice price, and nice review. OCZ has pretty decent units, but it's weird that you find so many refurbished units. I'd stay away from them.

Any Antec, quality Corsair or Seasonic is good.

even better price

you never know

i might do something like that in the future so i dont mind if it isnt going to be SUPER expensive compared to the 850w

Get the AX850 or an X850. Same PSU, just the corsair has a longer warranty IIRC. And just because a PSU advertises more watts, doesn't mean it can delivery or that it is better. Most of the PSU guys on this forum say that a good 850watt unit is good enough for 580SLI, so I wouldn't worry too much about needing more power. And if you do decide to upgrade your your PC to an epic gaming rig (quad GPU/dual CPU), upgrade your PSU then. Buying a more powerful unit on the dream of getting an awesome rig later on is silly.

Unless you plan to get an SR-2 ($550-$590) with 2 highly OC'd Xeons (~$1500 each) and Quad SLI GTX 580's ($450-$550 each), i heavily doubt you'll ever need 1kw or over.

Hell, the OCN PSU Guru, Phaedrus, says a quality 850w can juice up SLI GTX 590's/Xfire Radeon 6990's

"850 Watts @ 50°C" This is the important part. As you know for each °C above rated means like 5-7watt lost 50c pretty much means you'll always have full power.

An 850w is very unlikely to be to handle two 6990's or GTX 590's at least not without running outside its rated spec. Maybe if you keep the cards at stock and don't overclock them at all you might get by but as soon as you flip the BIOS switch on the 6990 that boosts it up to 6970 speeds and voltages its power rating goes up to 450w. I have two 6990's and when I tested at the wall with one of those cheap P3 Kill A Watt meters it was reading over 1100w.

You can read my post here for further proof that 850w isn't enough to be trying to run two dual GPU 6990 or GTX 590:
