Hi, thanks for reading. THe mother board has a green light thats on, the power button lights up on the case. I've tested the PCU with a paper clip and it also runs fine. When i start the computer nothing happens. None of the fans turn on, including the CPU fan. I hooked in my old PSU and still got nothing. My specs are :


Computer: CyberpowerPC Gamer Xtreme GXi250 Desktop PC with Intel Core i3-2100 Processor, 1TB Hard Drive and Windows 7 Home Premium
New PSU: Corsair GS 600
Old PSU: Turbolink Switching Power supply model :ATX-TL500W-BK

Also want to install a GTX 560 Ti Graphics card but i had my old stock GT 520 still in when i encountered this problem.

Did you plug in the 8Pin cpu power connector correctly?

I believe so. I split it into two 4pins and plugged the one with the correct shapes in the correct places and it slid right in.

Flip the two and see if the system powers up.

Well i have the old PSU in at the moment with its 4pin plugged in and it still wont turn on.

Okay so sorry about the delay forgot about this post. I got it to run by pressing the restart button on the front of the machine... kind of odd. Now the power button doesn't work and the reset button is used to turn it on.... but now it runs fine aside from that...
