Good Evening all,

I just finished putting my build together, and thinking that I was done, I plugged the PSU into the wall and made sure the power switch is on (I). But when I pressed the power button (first on case, then the power button on the MoBo) there was no response from any components.

I've tried the switch in both (I/O) directions and have used multiple outlets. Ideas?

CPU: Intel Core i7-3770K 3.5GHz Quad-Core Processor
CPU Cooler: Phanteks PH-TC14PE_RD 60.1 CFM CPU Cooler
Motherboard: ASRock Z77 Extreme4 ATX LGA1155 Motherboard
Memory: G.Skill Ripjaws X Series 16GB (4 x 4GB) DDR3-2133 Memory
Hard Drive: Hitachi Deskstar 7K1000.D 1TB 3.5" 7200RPM Internal Hard Drive
Video Card: Sapphire Radeon HD 7970 3GB Video Card
Case: Cooler Master HAF 922 ATX Mid Tower Case
Power Supply: XFX 850W ATX12V / EPS12V Power Supply

The 24 pin mobo power is connected, cpu power is connected, gpu power is connected...


On power up the PSU makes a small *click*. This doesn't sound like a sign of a DOA component to me, but maybe it is.

Thank you fort any help,
Dan

Take everything out/unplug everything but the CPU and 1 stick of RAM to see what happens. If that works add one thing at a time until you find the issue.

It COULD be a DOA mobo, though.

Or, it could also be that the mobo is shorted somehow.

if you must, pull everything out of the case, including the motherboard and put it on a cardboard box and keep the cpu, cpu cooler, and one stick of ram installed and see if it turns on. like DJ said, you may have a short...

Alright, so after taking out all components but on stick of ram the system booted. Then I added the fan connectors, it worked as expected, then added the other 3 ram modules and it booted perfectly. but when i try to plug any of the modular cables into the PSU there's nothing
 
Hmm, that's very strange. If it was a truly bad PSU or mobo, it shouldn't work at all. Are the modular cables plugged into anything (GPU, etc.) when you try that, or does it just not boot at all with the cables plugged into the PSU, even with nothing connected to them?

AHA! I had some random atx to molex cable plugged in and it had the wrong end on it. I think it was an adapter so i can power my GPU (8+6 pins) with molex instead of atx pins. I am tentatively saying problem solved, I will make another thread if I run into other problems!
