My mum desktop cannot be powered up

post #1 of 8
Thread Starter 
So her desktop was not turned on during that morning before the power cut off in the apartment building, she had turned the computer off the night before that power cut off happened in the next morning. But then she cannot turn on the computer after power is back to apartment and every other electronic stuff at home has power. The PSU is an around 2 years old CX430. This is the second one from official warranty replacement after the first one has been death also around 2 years. Does this sound like a PSU failure or something else? Because I don't always go to visit my mum, if it should be PSU problem then I buy a new one and go there instead of let her wait for me to go there again.

If when you press the power button, nothing happens at all (no fans spin, no attempt to power on, etc...) it is 95% a power supply issue. If you have another power supply to test take it and try.

Try the fuse in the plug (if it's a UK type plug - given your spelling of 'mum' I imagine it's possible...) wink.gif

I think so too thanks.

I don't know about US/EU plugs, but UK ones that come with Corsair PSUs have been ones which don't require disassembly of the plug.

A Youtube vid I found demonstrates both possibilities for changing the fuse in a UK plug. Might be worth changing the cable if you've got a spare. It's still probably the PSU, but checking the fuse takes like a minute at most.

try a simple thing first. Turn off the main PSU switch and back on. Many PSUs have a surge protection that prevents the PSU from powering up after a power loss. Mine does this. I just have to turn off and then back on and ta da it works again. Some PSUs have dedicated switches for this. I am unsure of your specific model. Also if you are plugged into a surge protector strip make sure that it is also not tripped to the off position.
