New PC build won't start

[col.frost1505]

I've bought myself a new PC (Specs down below). I have put everything together and now the CPU ezDebug LED lights up on start. PC shuts instantly off again. I've already switched CPUs to an RMA one.

Mainboard: MSI B250 PC Mate
CPU: I7 8700K
PSU: an old one unknown 450W
RAM: 8GB HyperX FURY DDR4 2133
M.2 SSD Samsung
GTX 1080

Well....the first thing that caught my eye was "PSU: an old one unknown 450W".
I would be checking the PSU voltages when you start to see if they are within specification.

Also...a 450w PSU I think is too small for a 1080.

This website gives rough estimates for PSUs and they recommend 520w minimum.

You may have a point there!
The troubleshooting list assumes that the components are all working and will all work together, so the final result of working the list should be a fully functioning PC.😀

Glad you got it straightened out!
