First i7 drew quite a bit of power from what I know, add 2 more cores annnddd

We had a heated discussion about this at one point.

I finally bought a kill a watt and the highest I saw was 670 from the wall, everything OC'ed including the TI's

Still shutdown three different AX 860's, bought a 1200i no more issues

Niceguy...If your set on an 860 you should get it, be sure to apply a load and see how it handles within the time you have to return it

Ti's are going to be more efficient than 580's from what I understand, and even more so than 480's before it

All kinds. Vsync off and on. I've spent a decent amount gaming where SLI usage gets near 100% for a sustained period. Vysnc just limits the usage.

I'd be surprised if my power supply was struggling. The cards draw a lot of power when both are at 100%, but at 1080p that's not very often on my setup. I plan on upgrading to a 1440p monitor, and I'm curious to see how the usage profile will change. However, I would not want to be running these cards at 90-100% 24/7 (such as when mining) unless they were set to stock clocks.

O.K. for the sake of absolute stability here....because were recommending a power supply to fellow friend here on OCN.

Run a taxing game with V-SYNC off, go into Nvidia Control Panel, Enable Antialiasing SLi CSAA x 64 at your cards maximum overclock

By the way if your cards aren't at 100 percent you won't really know if your power supply can stand up, so we can't really say your setup has no issues

Folding@Home would be far more taxing on the GPU's but I dont think they tax the PSU in the same manner

Don't know much about folding, but if the PSU can't even handle gaming thats pretty unacceptable in my book.

Running 780 ti overclocked makes a difference in games, especially at 1440p where you can enable Supersampling in games like Tomb-Raider, Splinter Cell, Thief....and run them smoothly

You may not think you want to overclock the Ti's now but they really shine at overclocking

If that's the case, then you might have other issues going on, like perhaps unusually unstable power from the wall outlet or something like that. I mean, delivering 603W should be a cakewalk for the AX860.

So I hooked up corsair link today to get a second opinion from the kill a watt on power consumption....

600 from the psu.....axesmiley.png

I've tried different wall outlets and the same shutdown, and again tried different 860's still shutdown

Could this be a faulty wire? I had three ssd's running off one power cord....maybe that?

I'm determined to get this 860 to work now

So I'm changing my reply to this thread, its gonna be YES....860 SHOULD be fine even at max overclock, (with stock bios of course)

My 840 EVOs say that they require up to 0.86A and that they run on 5V power. That's up to 4.3W per drive. 4.3 x 3 is only 12.9W. So, no. The +5V capacity of the AX860 is 125W, and here's typically what runs on 5V power:

Preferred voltage variation: +/-3%, 4.85V - 5.15V
Allowed ripple: <50mV
Preferred ripple: <30mV
Info: The +5V rail used to be the primary power source, but has since fallen out of major use. Even though it isn't a major power source, many of the things it powers are vital, so it must be kept tightly regulated. It also powers external USB devices like keyboards and flash drives and such.
It powers:
Some motherboard chipsets
Hard drive circuitry
Optical drive circuitry
Some fans
Some PCI cards
USB devices


-5V
Nominal value: -5.00V
Allowed voltage variation: N/A
Preferred voltage variation: N/A
Allowed ripple: N/A
Preferred ripple: N/A
Info: The -5V rail was removed from the ATX specification with revision 2.0, and is not allowed on modern ATX power supplies. If you have a PSU with a -5V rail, it is (or is based on) an antiquated ATX 1.3 era power supply which were designed to deliver most of their power on the +5V and +3.3V rails, and thus are not suited for modern PCs. It may have had the +12V rail beefed up, but that can't compensate for the outdated design. Any power supply with a -5V rail should not be used with modern PCs. In the cases where a PSU does have it, its power rating should not be added to the PSU's total output rating.
It powers:
Nothing



Further Reading

 

This is a little outdated, but solid state drives do run on 5V power.

 

So, I guess it's possible that you have a defective PSU.

Corsair Link is known to be junk software though unless they resolved that recently?
