Pc shutting off

Neil galvin · Monday at 23:42

hi guys, i have recently upgraded my CPU from a Ryzen 5 2600 to the Ryzen 5 5700x3d.
ever since the upgrade my pc shuts off randomly during gaming.it just shuts off to a black screen but all the lights in the pc are still on. some gaming sessions it will shut off and some it wont.
CPU temperatures get around 68 degree and rx6800xt GPU temp around 70 degree, so its not a overheating problem

could it be my PSU? i have a corsair rm650 80+ gold, is this enough wattage or do i need higher

i am genuinely stumped at why its shutting off.

Have you got another PSU to try?

Try the Ryzen 5 2600 again if you still have it.

Is anything overclocked?

no nothing overclocked and i don't have another PSU to try, i will have to get one i think.
il try the my old CPU to see if that solves it, although i never had this problem using the 2600 before

Did you reset your bios settings during the upgrade? It's possible that some setting that worked with your old 2600 doesn't get on with the 5700X3D.

If your PSU worked fine prior it shouldn't have an issue now unless it's suddenly developed a fault, the new CPU is hardly power hungry.

i updated bios but didnt reset settings, il give that a go, i asked the question of PSU as i seen people saying its a PSU power issue. but i also seen that 650w is enough for the 5700x3d and rx6800xt, so i just wanted to see what you guys say, so i could rule that out

The PSU has a single +12V rail so there won't be any bearing on how the power goes from the PSU. However, that said, check your power connections from the PSU to the GPU and make sure they aren't daisy chained. Meaning, use one connector from the PSU directly to the first 8-pin, then another, separate connector from the PSU to the second 8-pin. It's likely that the CPU has increased power draw and the PSU isn't supplying enough stable power to the GPU - thus the black screen. I have experienced this exact issue in the past.

TL;DR: Don't use a single PCI-E 6/8-pin cable to power both 8-pin connections.

This exact issue was happening to me for months

It was the PSU, put a new one in and no more issues since. The issue wasn't the wattage, the issue is a capacitor inside the PSU was dead

Did your old CPU work?

When you updated your bios, did follow the instructions from F40?

Note:
1. If you are using Q-Flash Utility to update BIOS, make sure you have updated BIOS to F32 before F40
2. Before update BIOS to F40, you have to install EC FW Update Tool (B19.0517.1 or later version) to avoid 4DIMM DDR incompatibility on 3rd Gen AMD Ryzen™ CPU.

This actually makes sense, so i found but not 100% sure, that when my amd adrenaline is set to performance mode, thats when it seems to do it.
This is my GPU connection is this wrong.

I am hoping its not this, as its not really that old at 4 and a half years old.

I havent had time to swap it over yet, and yes i followed the bios update correctly

Yep, that's daisy chained. Disconnect one of the 8-pins, then run another PCI-E power cable from the PSU to the 8-pin that you disconnected.
