PSU doesn't boot PC and clicks

[mnc221]

I have a Corsair AX760 and just built my new PC. However, when I switch the power on the PSU fan spins for less than a second and then it makes a click sound then stops. But all the lights on the motherboard are on and power is running through it. I tried this PSU on another PC and it is working perfectly fine. I tried all the other solutions on the forums but nothing helps. What can I do?

P.S: Specs are in signature

Thanks.

If the power supply worked in another system you connected it to.

But with the system you just built it does not, and clicking sound came from the AX760 power supply unit when you pressed the power button on your new build.

It can indicate that you have a short circuit at worst somewhere in the new system build.
The click is likely one of the power supply`s protection circuits being triggered.
As a result it prevents a full power up of the system to avoid any damage to the components, or due to a short circuit any sort of fire that may be caused.

In such a case you should remove the motherboard from the case and lay it on a non conductive surface.
Starting off with the cpu and cooler fitted for it.
And one stick of memory fitted to the stated memory slot of the motherboard.
Either using the onboard video of the motherboard first, or if you wish using the Pci-e graphics card by placing it in the Pci-e slot of the motherboard.
Hook the video lead up from the monitor to either graphics solution.

Add all of the power required for the motherboard, and the Pci-e graphics card.

And then tests to see if the system powers up with the AX760 power supply connected.
Use a small flat bladed screwdriver tip to short the two pins on the front panel header of the board for where the main power switch connector fits.

If the system powers on, and posts, without problems.
Shut it down again.
Then add another ram stick.
Test again and so on.

If it passes with all memory sticks fitted and boots.
Move on to connecting a Hard drive via the sata ports of the motherboard.
Connecting the Sata cable and power for the drive.

If it passes then.

You can conclude that the problem may be a short circuit for example when the board is placed on the cases motherboard mounting plate.
Where one standoff may exist touching the back of your motherboard because it is not aligned with any of the mounting positions of the motherboard where the holes are to screw the motherboard to the plate.

Remove the extra standoff if the case.
Then re fit the motherboard and all of the components.

Do everything step by step to make life more easy. Any part you fit that causes the system not to power up right when fitted could be the problem though, for example a dead or broken memory stick can often cause a system not to power up right.

Keep calm do it bit by bit like suggested and you will find the problem.

If you get stuck PM me, telling me how far you got before the system refused to power up, and the last component fitted.

sorry I didn't mention it but I've tried exactly that. I've breadboarded the system and everything is working one by one. I even checked for any shorts and there was nothing. but when everything was put together it did the same thing from the start. a little fan spin and click sound

You have a short to the case some where. Just have to figure out where. Do you have slightly taller stand offs to install the motherboard? Exactly what Shaun O said. Check each cable and make sure there's no nicks on them and then check the motherboard. I am betting that you have a short from the motherboard to the case somewhere. Just have to find out where. Remember that if everything powers up an works fine out of the case all of your components are fine. If the same components so not power up and the power supply shuts off like that you have a short to the case plain and simple.

I have a Phanteks Eclipse P400s case. The standoffs are pretty tall which leave a good gap in between but for a strange reason it doesn't work. Could it be compatibility issues with the CPU?

 

[indsup]

Not likely if it works out of the case it should in the case. I would check the cables and make sure there's no nicks that are shorting it out. Or one of the drives.

 

[mnc221]

took out the whole thing again (such a pain) and tested it without the case. It's exactly the same as before. clicks and shuts off. strange as when I breadboarded it the first time it was spinning

 

[indsup]

If that's the case it's more than likely the psu bad. Could be the motherboard also. Do you have another computer that you can test the power supply in? Or a friends computer to test it in?

 

[mnc221]

Yep, tried it on another PC and it works perfectly fine. Is there a way to completely reset the mobo itself to get it started? I've thought about it and it could be faulty mobo or incompatible PSU? I checked the corsair website and it doesn't say Intel Haswell Rrady like other power supplies do.
