Potential faulty PSU

post #1 of 4
Thread Starter 
Recently I will turn my pc on and after 1 or 2 seconds it'll switch itself off, then a few seconds later reboot itself and again cut out after another 1-2 seconds. Then it usually turns and stays on.

The problem is now worse because 9/10 the monitor wont receive a signal from the PC and goes into standby. I have to turn the PSU off at the back of the machine and switch it back on in order for the screen to receive a signal and switch on as normal. Sometimes it wont turn on at all.

The psu is about 10 years old now so I know it needs replacing. I did get a message come up on the screen saying something was wrong with it but now I cant get it again to take a photo of it, this is just after power up.

How can I actually diagnose it? So I don't go out and buy a new one and it turns out its another component?

You could try the paper clip test to see if it is in fact the PSU restarting over and over again.




At 10 years old, though, you're better off just buying a new one regardless if it's the issue or not.

I think you should just replace it. It's 10 years old and you're having problems that are impossible to explain. What brand and model is your PSU?

 

You can get the 550W SeaSonic G Series from SuperBiiz for $66.59: https://pcpartpicker.com/product/DPCwrH/seasonic-power-supply-ssr550rm

 

Or for $74.98 after a mail-in rebate, you can get the 650W SeaSonic FOCUS Plus Gold: https://pcpartpicker.com/product/WrNypg/seasonic-focus-plus-gold-650w-80-gold-certified-fully-modular-atx-power-supply-ssr-650fx

 

I'm not actually trying to recommend SeaSonic PSUs; it just so happens that these are the first couple that I can recommend when sorting the list on PCPartPicker by price. I can show you more, but I don't want to get too carried away yet.

Yeah I think I may as well just replace it as it's so old, i'll give the clip test a go. Thanks for the recommendations I will take a look.
