Question PC won’t turn on with the CPU plugged in ?

[Kwill232]

Specs:
CPU: Intel i7-8700
MB: Asus ROG Strix H370-F Gaming
Ram: Corsair Vengeance RGB pro 32gb (2 x 16)
GPU: Geforce 1050 ti
psu: EVGA 1000gq gold+

so I’m here today because I got a new psu (the one listed above) and when I went to set it up nothing happened. So I started checking everything one by one and have come to the conclusion that whenever I have the 8 pin cpu wire plugged in to the MB it doesn’t turn on.

Here is a video to better show what’s going on

EDIT: SOLVED, PROBLEM WAS THE CPU WIRE WASNT COMPATIBLE SO IT WOULDN'T TURN ON, GOT A NEW WIRE FROM EVGA AND EVERYTHING IS FINE 😁

Have you tried to use a different CPU power cords instead of the straight 8 pin plug try using the 4+4pin power cord most of the time this works, I have noticed the 8pin plugs are problem matic a lot!!!!

Yes I have tried a 4+4pin power cord and still got the same result

Have you tried a bios reset by pulling the cmos from the Mobo with the psu unplugged and hold power button on tower for 30s x2s

Yeah I’ve tried this and still the same problem, im not sure if both of the cables are bad or if it’s something else. Just crazy because all I did was shut it down and then it just would come back on

Did the power button get unplugged on accident?

Nah, I made sure it wasn’t that, and a orange light is stayin on (on the mb) when I plug both of the psu’s into it

Double check your ram seated properly
Also try single sticks of ram in a1

Just tried that, and still same problem, even tried moving it around all of the ram slots

The only thing I can think of at this point is faulty psu or the CPU power on the mobo is shorted somewhere, and hopefully not at the CPU because then you need to replace both Mobo and cpu

I see, thanks for the help

What is your previous PSU?

What is your previous PSU?

Not too sure of the exact name because it’s a company I’m not familiar with and was one of the original parts that came with my prebuilt at the time, but the company that made it is cybertron.

Were the cables of that PSU fixed or modular?

OK, you can't use an old CPU cable on the new PSU.

Try to reset the CMOS of the motherboard.

Why did you buy a PSU with outdated platform and useless 1000w?

New to computers and just simply thought I’d need it, didn’t look into it too much to be honest, I thought it was a sure upgrade from what I had so I got it

300w is plenty for your system.

300w is plenty for your system.

I see, is their any good a reliable psu’s you can recommend me ,by chance?

For now it's fine but if you want to take the unit to a new system with high-end RTX 3000/4000/RX 69xx/7xxx you can run in issues.

I see I see, so the psu wouldn’t be compatible with a 3000 series card. Do you know if I would be able to work around it if I upgrade to a 300 0 series, or would it be best to try and get a new psu to go with the card ?

Just try and when it runs in issues (coilwine, banging transformer, shutdowns) you replace it.

What modular cable are you using for 8pin motherboard connection? How is it connected?

The cable should have "CPU" written on connectors.
8pin CPU connector goes into PSU - CPU1 or CPU2 sockets.
4+4pin connector goes into motherboard (4+4 gets combined to make 8pin connector).

Sorry for responding so late, problem was indeed the cpu wire, got one from EVGA themselves and everything is smooth now 😁
