PC wont boot on after GPU installation

[Patchwerk]

I had to replace the components inside of a prebuilt PC after some unforeseen water damage in my home, and not wanting to get rid of it.

PC: acer aspire g3-605 predator

What got damaged:
-Motherboard
-Graphics Card

What I replaced:
-Motherboard
ASrock h97m Pro 4 Lga 1150
-Powersupply (Proprietary power connector on old PSU)
Corsair Series CX 600

I initially got these replacement's as a hold over, so I can still use my computer for day-to-day business, sans the gaming. However I had gotten a new replacement Gpu: Asus GeForce GTX, and when I slotted it in, everything should have been fine, it didnt require any 6-pin Pci-E Psu connection, but when i went to turn on my computer to test it, the computer wouldn't turn on.

I thought it might have been some problem with the GPU, so i removed, and it still wouldnt power on, and so, I removed all of fans, and external units until i only had my Cpu and the power connector's, still wouldnt turn on.

I am getting no indication's of power from the PSU, no fan spinning, no lights from the LED indicators on the case, no power to any fans on the Mobo.

Did it turn on before you installed GPU, after rebuilding?

Perhaps the powersupply also got damaged

It turned on, and i was using it weeks prior to installing this GPU, and the power supply was replaced post-water damage.

Try the paperclip test on your PSU to check there is life in it. If there is, it would point to the motherboard being the problem, although obviously that would be strange if it's new. All the GPU would have done is drawn more power, but there's no logical reason why you have this problem if the PC worked fine beforehand, other than the extra power draw causing your PSU/board to fail again.

Test your PSU with the paper clip test. If that works then check your headers from your case switch. Those little guys slip off easy if you are manipulating big clunky cards. Sometimes they just slip off. If that doesn't work, try jumping it on the board with a flathead to connect the power + and - (or try using your reset switch by putting it on there, then holding the button down). This will rule out a faulty switch. If it boots, its the switch, and if it doesn't then it is your board. Ensure that all of your power connections are secure. I've had a 4pin CPU power unclip and not post before.

If you can test the card in another computer, that would be ideal to rule out the card, but overall this sounds like what I mentioned above. If it is PSU or MoBo, contact the manufacturer. Sorry to hear that you're getting so much trouble from this. Best of Luck!
