HP desktop does not start anymore

HP Recommended
HP Pavilion Gaming Desktop 690-0009
Microsoft Windows 10 (64-bit)

Hi there,

My desktop suddenly dead today. It crashed randomly this morning for three, or four times, and then totally dead.

It looks like PSU is broken, but I am not sure of it. 

Does anyone have similar issues?

By the way where can I find a PSU, like L64961-800 for this desktop?

@neustone , welcome to the Community.


The symptoms certainly do sound like you have a failed power supply unit (PSU).  The motherboard is HP proprietary.  It has a 4-pin power connector.  You will have to buy a new PSU directly from HP.  Unfortunately, HP doesn't show the PSU's available in Canada.  Here is a Power Supply Cross-Reference Chart to see where I got this information:


Your specific model is not on the Chart, but all of the 690 series have the same connector.  You can find them on HP PartSurfer:


I suggest that you contact HP Customer Support to see if they can help you buy one of their PSU's.
