Strange issue with my PSU ?
Strange issue with my PSU ?
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.

No, CM MWE 650 Bronze isn't sufficient. It lacks quality in the power supply unit. In terms of wattage, it meets the requirement but falls short in build quality, which is the primary concern. The only solution is replacing it with a higher-quality PSU. Recommended good options include Seasonic models such as Focus/Vertex/PRIME, Corsair RMx/RMi/HXi/AXi, and Super Flower Leadex Gold/Platinum/Titanium. If you're looking for the latest ATX 3.0/3.1 PSUs, check this link: https://hwbusters.com/best_picks/best-at...e-busters/. My current setup includes two PRIME TX-650 units and one Focus PX-550, with full specifications and photos available in my profile. A 550W unit works well for your build, and a 650W unit is also fine.
No, CM MWE 650 Bronze isn’t sufficient. It’s a low-quality PSU. In terms of wattage, it’s adequate, but the build quality is the main issue. The only solution is to replace it with a better one. High-quality options include Seasonic Focus/Vertex/PRIME, Corsair RMx/RMi/HXi/AXi, and Super Flower Leadex Gold/Platinum/Titanium. If you’re looking for the latest ATX 3.0/3.1 PSU, check this link: https://hwbusters.com/best_picks/best-at...e-busters/. My three PCs are also powered by Seasonic, with two PRIME TX-650 units and one Focus PX-550. Full specs with pictures are in my profile. A 550W unit works fine for your setup, and a 650W unit is also acceptable.
Never compromise on the PSU! Because it powers everything, it’s the most critical part inside the PC. Even if you opt for a cheap PSU, the return policy will give you the same product as a replacement, which you’ve already discovered.
The overall build quality is quite weak. So, what really matters is just the GPU.
Still, even though the rest of your build is budget-friendly, it doesn’t mean you can skip the PSU. Cheap, low-quality PSUs cause various problems, as you’ve seen before.
Thank you for your reply. I realized the wattage was too high. Quality-wise, the PSU isn't very good. I didn't notice it before. Now it seems like the right time to swap it out. I thought I shouldn't have gone for such a cheap PSU. The old one that came with the case also failed when I tried to replace it—literally! And yes, I know my build isn't great, but I just wanted to test what I could achieve with something like this. Thanks again for your quick reply. Have a great day!
The office and web browsing setup works well. Gaming performance is limited, so go with 1080p Low or 720p. Installing a GTX 1070/1660/1660 Ti will enable high-quality 1080p and ultra gaming, as the CPU handles it easily. Also, 16 GB RAM is sufficient for most games. A new power supply unit is essential.
Sorry for the delay, I changed my PSU but it didn't resolve the problem. What should I do next?
The replacement PSU's make and model (or part number) is provided. The age of the replacement PSU is also noted, along with whether it was purchased new, used, or refurbished.
Sorry I overlooked that part... The unit is the MSI MAG A650BN, brand new. I verified through reviews and the PSU tier list. It got a 4.5-star rating on Amazon and is a Tier C PSU in the list. Another odd point is I reached out to a friend who uses the same Cooler Master PSU (550W) and doesn’t have this issue. Could this suggest another problem? Also strange that this issue only appeared with the cooler master and didn’t show up on an older PSU I tested...
