Here's what I expect to have some time in the not-to-distant future...

i7-3930K with appropriately OC awesomeness mobo
2x tier 2 or 3 nVidia GPUs (currently would be 2xGTX 670)
2 or 3 large mechanical hard drives in RAID (right now would be WD Reds)
3 or 4 SSD's
1 Blu Ray burner
Gigabit NIC
Water cooling with 1 or two 655 pumps (or the equivalent - likely just one)
Up to 14 120mm fans (push/pull on a couple of 360 rads and a couple for HDD's and general air pressure adjustment)
Fan controller/monitor panel
4 or 5 external USB devices

I can't think of anything else I may be adding, but of course you never know. All that said, would a quality 850W PSU be a good choice? I've been looking at 1000W, just to be on the safe side, but I really don't want to go too far above the high end of what I'm actually going to be using.

Here's one I've been looking at (love the modular CB radio style cables): http://www.newegg.com/Product/Product.aspx?Item=N82E16817703039

If I *do* need to go for a 1000W, what's the consensus on the Lepa's?

You'll be fine with a good 650w unit. I use a Corsair AX650 in my build and I have never had any problems, even with my cpu up to 5.3GHz with close to 1.7v with my gtx690 at high clocks.

See sig GTX 690 3dmark11 score, done on my 650w psu.

An 750W is ideal, a good 650W would work too but if you're going to push the 3930K it gobbles up the power. That's a great PSU, there is better for the price but if you like the cables then go for it

I'd be interested in hearing any suggestions for something better for the price or same quality for less money.

Thanks.

are you ocing the gpus heavily? volt modding?

Corsair HX750, Seasonic X750.

Little lower quality, but much cheaper: http://www.newegg.com/Product/Product.aspx?SID=y2Kr2n7ZEeK3QR40xRvYTA0_8ISS3_0_0_0&AID=10440897&PID=1225267&nm_mc=AFC-C8Junction&cm_mmc=AFC-C8Junction-_-cables-_-na-_-na&Item=N82E16817153167&cm_sp=
Good review at : http://www.hardwaresecrets.com/article/Thermaltake-TR2-700-W-Power-Supply-Review/1422

To be honest, newegg helps you out a ton here because they tell you if "jonnyguru" recommends it. I trust jonnyguru's psu reviews more than anything else, so anything he recommends is great.

There are many very high quality power supplies out there

These are all the good ones I could find on Newegg between 600W-700W.
Regular Aurum up there (not Aurum Pro or Xilenser) is not so great.

Of those, at those prices, I would take the Lepa.

If you're going for really high overclocks, expect to FurMark + prime95, etc. then the Kingwin Lazer Platinum is a slight upgrade over the PCP&P MKIII under 1200W. LZP-750 is $136 (after promo), $106 after rebate as well:

Or just the PCP&P if you want to spend some extra for those connectors.

Be careful. The power supply at newegg is TR2-700AL2NC-A. The power supply that's 80 plus bronze, reviewed by hardwaresecrets, and on the recommended PSU page here is TR2-700AH2NFB. The good model isn't just "little lower quality" than PCP&P Silencer MKIII 850W / current Corsair HX / Seasonic X (there's more of a gap), but the actual unit there may be significantly under the one you're thinking about.

If you going to be overvolting then go for the KW.

I have drawn around a KW from the wall with 2x 7970's when benching. There are some images on here somewhere of my power draw.

Others may, in fact will disagree, but I don't believe there is such a thing as overkill on power supplies when you start getting to high end PC's and overvolting them.

Best Regards,
Stu.

Now granted, you're suggesting a GX model, while the review above was on an RS model, but still it seems to me that any manufacturer that would sell a product that fails so miserably is not a manufacturer I want to trust a couple grand worth of computer equipment with.

Thanks for the suggestions. I'll look into the others.

The GX line is very good and has no issues so I wouldn't rule it out. Other Cougar PSUs are a bit bleh though.

Thanks for all the suggestions. I gave in to my general nature of overkill and pulled the trigger on the PC Power & Cooling Silencer Mk. III 1200W. ($249.99 at NCIX right now).

I know I have no need for that kind of juice, but I plan to use it through every bit of the 7-year warranty, and who knows what I'll need in the future. It's also nice that this thing will hit 600W of output, before the fan even spins up - nice for a silent system.
