HP Envy 750-170se CTO - PSU Power on Issues

HP Recommended
HP Envy 750se Core i7-6700
Microsoft Windows 10 (32-bit)


To summarize, I did a CTO build back in 12/2015 and used the HP Envy for about a year before my power went out. Envy wouldn't power back.  I was past RMA so decided to replace the PSU with a Corsair RM850x.  All my parts have been sitting until now so I swapped in the new PSU and tried to power on and it only made a quick click and nothing. No fans or anything.

So my hunch of the PSU being bad is fading and I'm trying to decide how to test further or get another main HP IPM17-TP /THIMPHU board. $200.00.

Any thoughts for this issue or further testing?

@MeThought , welcome to the forum.


I know that it sounds crazy, but did you test the new PSU to assure that it isn't DOA?  I replaced a PSU a few years ago and when I received the new one it was DOA.  It took me several days to believe that it could be true.  If it is good, you should check the capacitors on the motherboard to see if any of them are bulging.  Also, test the memory by removing all of the sticks and replacing them one by one.  The single stick should be placed in the slot closest to the processor.
