PSU Problem!

[NoobishStyle]

So I was using andyson F500M PSU previously. But I recently got a gtx560ti and I decided to change a new PSU. Bought a Seasonic G-Series 750W. Problem is I plug in the 750w my computer no beep and won't start but when I use my old 500W can start. I bring back the 750w. I brought the 750w back to sls and can work on their computer. Bros please advice.

You confirm connect all the cables properly? Dun connect PCIe cable into the mobo's 4+4 pin header.

There could be somewhere in the connections have been shorted. Remove the GPU and reroute the wires again. The PSU is protecting itself from turning on.

All connected properly but still not working :/

Wah then like that like ive mentioned. Somewhere shorted le. lol

Do the Frankenstein method.

Put the PSU outside the chassis. plug in one by one.

Make sure you connect both the 4 or 8 pin cpu power, 24pin mobo. Make sure HDD or SSD got power. everything connected.

You can further test it by doing the paperclip test on the PSU. Go youtube check what is paperclip test on PSU. There is some guides there and you can jump start it. If it moves then most probably somewhere shorted or things have been damaged/spoilt.

PSU currently outside the chassis. Bo bian think need to try every available method. I go try again. Hopefully not something damaged of spoilt ba since old PSU can get it running. Oh well will keep give an update in about a few hours time LOL

I tested out the PSU again did the paperclip test all those still not working. Could it be possible that the Seasonic G-Series 750w not compatible with my AMD processor? I plug in the 500w PSU got beep indicating no ram and gpu but when I plug in the 750w nothing happen

Can't be. Do you have another computer to test on? Tried changing the cables for the 750?

If the paperclip trick doesn't work, it can mean that the PSU has a underload protection.

There is a rare chance that the mobo and the PSU are incompatible:

Tried with another video card yet? PSU-video card power good signal time sync can sometimes be off.
