1.375v is high for 4400 Mhz
My 5600x processor does 4600 Mhz @ 1.25v with the new MB.
I have the Ryzen 9 3900x max Clock it 4600Mhz Single thread I think your has a max of 4,700 single thread or thereabouts and the new 5xxx CPU are more power efficient

And if I try my actual PSU on another computer, it should do the same even if the PC requieres less power than the actual RTX 3070 + 5600x I have ?

I don't know if try first to send my MB or not before trying the new PSU

You can test ur PSU on another pc even if ur other pc consumes like 50W. From experience as a pc technician in my early days is that a PSU works or does nothing. Nothing in between. A PSU should also last for more than 6 years.

So you think that the reboot can be caused by the MB ?

Hello. Today I build new pc and have the same problem. 5600x, B550m bazooka, 16x2 Crucial Ballistix Desktop Gaming Memory 3600 MHz, Radeon rx580.
After fresh windows install I had random reboots every minute.
Now I change ram frequency in bios to 3200 MHz and no rebooting on windows anymore. But when I run 3d mark (time spy and fire strike) I have reboot in 3 sec. after benchmark started.
Not sure if it can be PSU problem, but before I had i7 3820 with the same graphics card and PSU without any probnlems.

I have a feeling there is a problem with the Bios. Hopefully they release an updated bios version that fix these issues.

MSI support suggest me to update bios to a52 beta version. But it goes worse. With new bios my pc restarts every time on Mag logo. Still not sure what is a problem. Will get new psu in 2-3 days and check if it fix problem

For Zen 3 and Zen 2, a spontaneous reboot without any event logs usually means unstable CPU core or unstable Fabric Clock. Unstable fabric clock can be mitigated by running your RAM at full stock 2133 MHz (do not use XMP, disable XMP). Unstable CPU core though... make sure you are not enabling precision boost overdrive and not using curve optimizer (they are off by default). Regular precision boost is a stock behavior and should not be disabled unless you want to double check that it runs fine or not at base clock.

I have only had 1 rare instance where a bad power supply was giving dirty power and causing BSOD's on an older intel system so a bad PSU could cause issues too.
