You were not cutitng it close with a HX850 and two overclocked GTX 470's.

@OP The AX850 is ample for GTX 480 SLI.

850W IS NOT CUTTING IT CLOSE FOR TWO GTX 480's. 750W WOULD BE CUTTING IT CLOSE.

Curious, what do you define as cutting it close?

Thanks and + rep! Unfortunately with ca tax and shipping it's more than the standard amazon price. Given that I can't afford the 480's yet I may wait for a better deal or a 2nd hand one (though I've yet to see a 2nd hand one). I was mainly asking now because the AX850 went on sale and I wanted to know if I should jump on it.

Thanks everyone I think I'll wait for the 1200 as I'm not sure that I won't want to go tri sli in future.

Of course, how important cutting max load close to max rated capacity is, depends on how you use your machine.
If you don't fold or bench a lot, then having your maximum load at or near the maximum output of a good PSU is fine, since you won't get anywhere near that load in normal use.
I mean, how often do you run something that will stress ALL your GPU and CPU power at the same time? Not often. Most games will manage only half to 3/4 of that loading.

If you fold or have your homepage set to HWBOT, then buy a PSU that most people call overkill, every time. Everyone else can cut it close quite happily.

sorry, meant more specifically, like a certain % of a units rated capacity, 90%? or within X watts of its max?

Not quite sure if you're agreeing with me or not But I don't usually recommend Powersupplies based on the fact that it can only handle typical gaming load before getting close to or beyond its rated wattage.

You can run games on it. But you want to do water cooling and stress test the system there isn't the 20% buffer there should be. A shame they don't make 1000w ax model. Also the ax models become a bit noisy above 80% power consumption as far as know.
