But yeah, AX > HX.

And yes, AX is the same as SeaSonic X-850, however, with stronger Switchers.

Personally, I'd get this one. It's better than both IMO. But you can get the AX as well.

So would you buy the Antec Quattro 850 if you were in that price range? or the Corsair AX-850? I only like the corsair better because it has the 4x 6+2 PCIe connectors instead of the Antec's 2x 8 PCIe pins and 2x 6 PCIe pins, which isn't it better because its a little more flexible in terms of connections?

Question: Price isn't and issue and 850w is the max I want/need, what psu would you buy?

Another one: A good 850w psu under $250.

Thank you

Yep. You wouldn't be running something that would require dual 8-pin's or two on a 850W unit anyway. That would be 6990 Quad-Fire, of which you'd want a little more power to run all OC'ed (unlocked)/overvolted.

The TPQ-850 at most peaks up to 34C in hot box at full power, while the AX does it at 48C. So it runs cooler with the 80mm fan orientation (which isn't a loud one). It also has the protection of multi-rail OCP, that means possibly less parts to be lost in case of a complete system failure (blow up ).

One more thing is it doesn't have the little ripple fluctuations AX had. Plus, regulates a bit better.

IMO, the the AX850 isn't worth the extra unless you really want the partially fanless operation or fully modular cables. In terms of performance and build quality, the AX850 isn't 35$ better.

They both perform pretty similarly, with the HX850 slightly edging it out on the minor rail vregulation.

Minors aren't as important as the major rail. In reality, systems don't use +3.3v and +5v just as high - concurrently like a load tester does. Even when they do, they still aren't as relavent as +12v. There're many PSU's (including some older ones) that beat the HX.

They aren't as important, but still pretty relevant. Regardless, the AX850 doesn't have better +12v regulation either. My point is that besides features (like fully modular cables/quieter fan), the AX850 doesn't offer much to warrant the extra $35, and it has slightly worse performance in some regards.

I wont be SLI'ing another ASUS DCU2 570 thats for sure it wont fit (with a slot in between) in my mobo, so I will probably SLI a MSI 570 Twin frozr 3 which then only needs 2 6 pins so in total one 8 pin, three 6 pins. for SLI'ing 570's later on. thats why I need more models because the AX-850 only just has enough PCIe adaptors for SLI'ing for me :S and tats the only reason I'm turned off the TPQ-850 because it has the 2 8 pins and 2 6 pins

@ OP, link the shop/s you intend to buy from for different suggestions.. Corsair units are priced pretty poor in AU, chances are you can do a lot better or save some serious cash going for something else.

So what psu would you recommend with enough power for my sig rig with sli in the future with one 8 pin, three 6 pins?

850w is over kill but 750w is the lowest I can go, im not an expert with psu's that why I made this thread.

or

http://www.ddcomputer.com.au/index.php (I know the bloke who owns this so I can get these cheaper)

Its a matter of what is the bet for under $250 AUD that can handle SLI in the future with one 8 pin and three 6 pins so around 750-850w psu?

Well yeah, there certainly are better options to each; as pointed before. For example, here's an Andyson MT-9 1000W with caps on the modular board to increase capacitance (reduce ripple). For $150, it's an amazing deal. Very similar to BFG EX1200.
