guys, I had 4 gpu's running in a rig I upgraded the psu so I could plug 6 gpu's and now that I try to turn on the system, it won't boot. The psu makes a clicking noise everytime I press the rig's power button. Did I unplugged something wrong from the previous psu? I have an external dvd/cd usb attached to the mobo, that and the power button turn on so could it still be the mobo or is it something else I'm not plugging in right? I re-plug every single connection, sata cables, pci-e, cpu, power and nothing, I even replug the old psu and that one is doing the same thing when I try to turn on the rig instead of making a beeping noise like new psu, it makes a buzzing short noise. Any help appreciated.
Quiet curious since you have just been upgraded the PSU, Are you sure you did connect the right connections similar to the older set-up? The PSU isn't the main problem here even though it make clicking sounds I agree on what been suggested above, try to plugged and unplugged some components you will actually see what causes the problem.
Please do give feedback if what happen.
