A)1st, try re-connecting the cables, CPU, wires, RAM and making sure that you got the proper cables/wires (including cpu case wires) in their proper places. Turn it on again

B) If it still powers down try resetting/running Bios on Default. Even if it is just run default anyway.

C) If it still powers down afterwards do the following:

1) Remove Graphics Card
2) Enable onboard graphic card
3) Power On

From there you will be able to assess if fault is wrong connection, bios setting or PSU
