Does this sound like a PSU issue?

So basically I have 2 PC's in bits around me, and I believe that the PSU is causing the issue. First the bits.

1st
Asrock z68 Extreme 4 gen 3 Mobo,
i5 2500k
Kingston hyper 8gb ram 1600mhz (2 sticks)

2nd
Gigabyte x58a udr (Was RMA and returned a few days ago)
i7 920
Patriot Viper 6gb RAM 1600mhz (3 sticks)

Both parts are being built out of case with Intel stock cooler to test if they are working. Both are using Asus 5850 direct CU GFX card and both tested with my HX 750W PSU from Corsair.

The problem.
Same issue with either build. As I said Ive build out of case to test parts. When plugged in and powered up the PSU fans, GFX card fans and CPU fan all start to turn. Within 1 second the fans stop and the power dies. Exact same issue with both builds, neither build reaches post.

The only common components in either build is the gfx card and the PSU.

Im guessing the PSU is at fault here but any other suggestions as to possible cause?

Thanks
 
I assume all power connections are connected, the 8 pin for cpu power and the main 24 pin tax connector.
 
Yeah both are connected. I actually went and double checked this to make sure I wasnt being a complete idiot :D
 
yeah i had a psu do somthing like this the fans just went very slow then stopped after 30sec.. i would try boot your pc with the gpu out and no other cables attached.. see if this makes the fan do the same.
 
Just tried to do the paperclip test as well.

The PSU fan will start to move for a few seconds before dying off as well. No matter how much I wriggle the paperclip the fan wont stay on for anymore than a few seconds at best.
