Question Strange issue with my power supply.

[Ashokisordinary]

Hello! This is my first time posting here.
So I have a very strange issue with my PSU. I bought it about 2 years ago due to a cheapo PSU that came with the case failing (thankfully didn't take anything else out with it). I have a Cooler Master MWE 650 Bronze V2 230V PSU. Ever since I got it, I've had this issue. Basically with my previous PSU, when I would Shutdown my PC, the Drive activity light, would blink a few times before shutting off. Which indicates that the boot SSD has completely written everything and shuts-off. Take a Raspberry Pi for example. It blinks consistently for a few seconds before shutting down. But with this PSU, It doesn't do that. It shuts off with a relay click as soon as the secondary HDD spins down. This is completely unusual behavior which I can confirm does not happen with another PSU I tested with. This causes slow boot times. It went from just under 2 seconds, to about 10-15 seconds to boot. I'm worried this will reduce the life of my SSD. Weirdest part was, about 9-10 months after I bought this PSU, this problem went away. But that coincided with me getting another problem with this PSU, which made the HDD Spin up and down constantly. So I RMA'd it under warranty and got the same model PSU as a replacement. But this replacement has the same issue with the SSD. How do I fix this? It's driving me crazy. I tried disconnecting the secondary HDD, to no avail... Tried changing some BIOS Settings, to no avail... Please help.




Specs:-
PSU:- Cooler Master MWE 650 Bronze V2 230V PSU (I know it's a little too much)
SSD:- VTRUST 256GB NVMe (Boot Drive)
HDD:- Seagate Barracuda 1TB (ST1000DM010) SATA III (6.0 GbPS) (Secondary Drive)
RAM:- Crucial 2x8GB @ 2667mhz DDR4 (IDK the exact specs but I think CL19)
CPU:- Intel Core 13-10100 @ 3.6GHz 4 cores 8 threads
GPU:- Nvidia GTX 1630 (Don't judge me for it...) from MSI (MSI Ventus XS 4G OC)
MOBO:- MSI H410m Pro-VH.

No, CM MWE 650 Bronze isn't enough. It is low quality PSU.

Wattage wise, yes, it is enough, but not on build quality wise and that is the main problem.

How do I fix this?

Only option is PSU replacement and that, with good quality PSU.

Good PSUs to go for, are: Seasonic Focus/Vertex/PRIME, Corsair RMx/RMi/HXi/AXi, Super Flower Leadex Gold/Platinum/Titanium.
Or if you want the latest ATX 3.0/3.1 PSU, then: https://hwbusters.com/best_picks/best-atxv3-pcie5-ready-psus-picks-hardware-busters/

(My 3x PCs are also powered by Seasonic. I have 2x PRIME TX-650 units and one Focus PX-550 unit. Full specs with pics in my sig.)

550W unit does fine for your build. 650W unit doesn't hurt either.

I bought it about 2 years ago due to a cheapo PSU

NEVER cheap out on PSU! Since PSU powers everything, it is the most important component inside the PC.

And even if you buy a poor PSU, PSU RMA will get you the same junk as a replacement, as you've already found out;

So I RMA'd it under warranty and got the same model PSU as a replacement. But this replacement has the same issue with the SSD.

So, do look towards good quality PSU, like the ones i talked about above.

Nvidia GTX 1630 (Don't judge me for it...)

The whole build is equally weak-ish. So, what's there to judge just over GPU?
Still, just because the rest of the build is low-end, it doesn't mean that PSU can be cheaped out on. Cheap, low quality PSUs produce all sorts of issues, like you've already found out.
