June 29, 201411 yr Power supply is Raidmax rx-1000ae 1000 watt. 4 12v rails, 36a each. http://www.newegg.com/Product/Product.aspx?Item=N82E16817152044 I'm looking at my options to eventually use two gtx 780 SLI. "Requirements: Minimum of a 600 Watt Power supply. (Minimum recommended with a +12 volt current rating of 42 Amps.)" I read this about my psu's power output: Max combined 75 amps between the rails. http://www.hardocp.com/article/2011/02/23/raidmax_rx1000ae_1000w_power_supply_review/2 Is the current PSU not going to be good enough for SLI with the available amps?

It's more than enough.
June 30, 201411 yr Author That makes me feel better, but I had forgotten to add that the proc is a 2700k @ 4.9 GHZ, which I figure is about 200 watts at full load. With the H80 pump, hard drives, other fans, and miscellany, I'm adding in another 50-100 watts for good measure. I'm estimating 500+ for the gpus. The psu is over 2 years old and has been used mostly 24/7, never under substanstial load, but almost always on. I realize the specs still leave some overhead, on paper, but I don't know if I should be concerned about degradation of it's capacity.
June 30, 201411 yr I just went through this and upgraded my Corsair AX850 to an AXi1200. I had not done 3-way SLI with my 760's before, just 2-way and used the 3rd for PhysX, and it was OK. However, it struggled with the 3-way SLI for some reason. Your 1000w PSU should be ok, though.

July 1, 201411 yr Augh! No. One card wants to remain unrecognized and the fan on the card runs at 100%. Updated drivers and BIOS, rolled back same, I swear, nothing works correctly since new drive installation and P3D. Aarrrgh! On a better note, ASUS ROG may be sending me a beta Haswell-E board and choice of processor for testing in late Aug...
July 2, 201411 yr You can pickup an EVGA 1300G2 that's rated at the very top; right next to Corair's AX lineup for only $195. You can read up on the reviews on the Web; but if you're going to pick up a 1K PSU, you won't find a better power supply for the money with a 10 year warranty too. EVGA sells custom braided and colored PSU cables as well. I own the PSU. It's been very reliable: http://www.newegg.com/Product/Product.aspx?Item=N82E16817438011&cm_re=EVGA_1300-_-17-438-011-_-Product Specs: Custom Waterloop 2 ASUS GTX 780 Poseidon's in SLI ASUS Z97 Deluxe Intel Core I7 4790K 5GHz (1.40Vcore) 4 2,350 RPM High performance fans 3 1600RPM fans Lamptron Fan Contoller 4 Sticks of RAM (DDr3 2400MHz) 4 SSDs 7 USB Devices Power supply is rock solid, Jake Intel Core i7 4790K (5GHz; 1.40VC) SLI-ASUS GTX 780 Poseidon ASUS Z97 Deluxe P3D V 2.2 - ORBX Global+Vector; REX 4
