PSU wont boot properly

[darkgandara]

Just got a new PSU. (at least it is still new in the box). OCZ ZX 850W gold modular power supply. I swapped this PSU out with my other Azza 500W. Azza works fine just upgrading for more power. I get everything plugged in and go to boot the system. All I get is a single click withing the PSU and no boot. I know everything else works fine. I tried replacing ram and unplugged and replugged everything. PSU test shows that it works just fine. Solutions? Someone mentioned a possible grounding issues between the standoffs on to the mobo and case.

Specs-

I7-4770k
MSI Gaming 5 mobo
10 GB DD3 1333Mh Ram Corsair
Nvidia GT 640 2GB
128 GB SSD
256 GB HDD
(2x) 1T HDD
Cooler Master Storm Stryker case

Unfortunately, you could have fried your motherboard. Did you get any static shock? Also, make sure it is tightly plugged in and the same to the components.

I think you just received a bad power supply RMA it and you should be fine.

PSU test doesn't mean it's worthy to power up a complete system

Everything else works and is working fine. PSU is only issue. More inquiry suggests the actual power cable that im using may not be up to par as well as the possibility of the acrylic on the case causing a grounding issue. Also PSU test shows the OCZ works and powers just fine.
