hi gurus, my newly DIYed com has been switching off by itself.

basically it justs turns off, and cant be turned on anymore. If i try to turn it on immediately, the GPU lights and whatever lights in my com does flicker (like power being given but cant fully boot up kind) and then blacks out again.

Does it sound like a PSU problem or lack of power of the PSU?

specs-
6700k
zotac 1080
1 SSD
1 HDD
2 sticks of ram
powered by 650W gold seasonic PSU

the ram leh? try using only 1. sometimes it's defective ram. but if u already eliminated ram as a possibility, u got a backup psu to test if the mobo is working?

Confirm is not PSU not enough power,

Try what others said first (1 ram/ reseat heatsink etc) though I wouldn't rule out PSU fault.

using msi z170 pro gamer

CPU cooler seems fine, temp is fine, just adjusted to be safe

mobo stands all on, i counted all as I screwed in one by 1

it shut down as if it has no electrical current at all

When it shuts down, i cant boot it immediately if try so.
Instead, it will just give a short burst of power enough to light up the GPU lights, and the cooler lights, fan, then die off.

Seems like capacitor still holding enough power just to do that then die kind of look. Not so much of an electrical person, so not sure how to explain.

Then i will have to wait awhile, turn off the main power and switch it on, then i can start it again with no problems.

Try another PSU? Seasonic PSU is known for power on issue.
