New PC build,no power

Just to check something. Have you wired in the pc power switch to the motherboard connector? Does the PSU operate correctly and your rig POST when you have the power switch cable connected?

Yeah. Tried a different cable and monitors my existing one. My monitor works over HDMI on my old PC. Did try my old GTX 460 but it's been in a drawer for years so unknown if it's a reliable tester.0

@custardy
Have you checked with MSI whether your Corsair RAM is QVL tested? Ryzen boards are really fussy.I work within the voluntary sector, supporting vulnerable people to rebuild their lives.

I just built a Ryzen 5 3600 system you may have seen on the other thread, but my main fault was me! all working now (I needed a graphics board as 5-3600 can't do graphics alone) and a Ryzen motherboard won't even POST without some sort plugged in.
Twice I had heart stopping moments its had gone wrong again because I am so dopey I had reinserted the HDMI cable into the motherboard socket (from which nothing comes out) instead of the graphics card hdmi socket..lol so dozy!!!
I also had some initial lock up problems from messing with the bios. Had to clear it a couple of times by shorting the batt pins whilst powering up. Its been fine now I left it alone.0 -

I built pc's for a living for 6 years(retail shop). Recently built similar build to your own for my 16 yr old son.
Common things that give this problem are:
1. PSU not powerful enough for the system. Many may claim to be 700 or 800w but that might be way off the mark. A sign of quality was always the actual weight.
2. Reset CMOS/If possible update to the latest BIOS. It might not be possible if DOA motherboard.
3. Change ram.
4. correctly seated cpu/artic silver applied properly.
5. Fuse in the power cable. Swap it.
I have rarely seen DOA motherboards but it does happen.
Personally I have never seen a dead CPU since the XP 2000 Athlon days and that was due to people snapping the core during install lol.
The most common for me was always PSU/RAM.
I hope you get it sorted.

Ordered a new CPU & ram.
Plan to swap the ram out first.
Cant be the motherboard by elimination.
PSU well thats one for if the other parts dont work.
CPU has had new thermal paste applied,seated cleanly.
swapped PSUs & power cables already.
Main issue is I havent built a PC in years where as previously I always had spare bits n bobs to swap out & test with.1 -

I had a test bench and with parts this kind of diagnostic would take a few mins.
Lots of motherboards really did need the latest BIOS for that CPU to work. At a guess this is gonna be PSU or Board.0 -
Well back again.
16GB of new DDR 4 installed. nothing changed. Exact same issue with not powering on and no video once forced to power on. (built out the case)
tried 1 and 2 sticks.
Tried the old & new PSU
Tried the new 1660 gfx card and the old GTX 460
New CPU arrives tomorrow.
I have 3 motherboards here right now! 2 on the X570 chipset and one on the B450. All listed as Ryzen 3000 ready so I cant see it being the mobo.
Now tried 2 separate sets of ram,
2 separate PSUs. Whilst the old one is pretty old. whats the chances of it having the same fault as the new one?
This rig draws less power than my old one did.
Tried 2 gfx cards. Again whats the chances of both causing the same fault?
Really I can only see my left with CPU or simply neither PSU is up to it but both should have plenty headroom on the systems power requirements.
Its lucky I dont drink!
