I got a new GPU and PSU today and I've set it all up but when I press the power button it only turns on for a split second before all the fans and lights shut down. I did the Paperclip test on the psu and it seems to be working fine.

What could be the problem?

Specs:
Intel-I7 3770k
16GB Kingston RAM
Sapphire HD 7850 OC Edition

Anything else you need to know please ask.

Make sure you have all the psu cables plugged into their necessary slots.

It usually happens when a motherboard cable is in the wrong place, take them all out and start again.

Are you sure your motherboard is rated for the PSU? Also, try removing the new graphics card and starting it. If your machine is overclocked or you have your CPU unlocked adding a GPU to the system can cause it to become unstable. If it comes back on without the GPU, remove any settings for overclocking or unlocking and that should fix your problem.

My friend had this problem and needed to replace the power supply.

That's just my guess honestly i never touch my computer anymore so i have no clue but my friend had the same issue.

I wish you the best of luck with your computer troubles!
