Are you making that determination from Amazon customer reviews?

I checked the PC Cultists PSU Tier List [cultists.network] and am not sure if I can find this PS on that list. It may be this one, in "Tier C - Low end"
Cooler Master | MWE V1 Bronze [MPX] =>600W – Masterwatt (TUF)

Anyway, the power supply is very important. If it's uncertain how well it works, may be better to consider another one. Great price though! Repping OP for the find. Potentially good for the right person/PC build.

Huh… 4.6 out of 5 on 2,245 reviews is considered "really bad"!?

Semifanless... Either it has a fan or doesn't.

Rule of thumb,

Linus Tech Tips maintain a tier list for PSU. This one lands in Tier C. Its always good to get a A or B tier rated product but I got this for a budget build and have built many PCs off of Tier C / D.

Always do your due diligence on your PSU from researching to testing upon arrival.

I agree with that advice! I bought a Corsair PSU (80+ gold rated) for my high-end build. For the NAS server, I got a Tier C PSU from EVGA (80+ bronze). Both have been fine & are nearly silent.

FYI, the link above is for the old version (rev. 14.8), published 7-27-21. Check the link I included above (post #3) for the latest version of the PSU list (rev. 16.0b), published 6/11/22.

I noticed Linus Tech Tips doesn't maintain the latest version anymore.. for that you gotta go to the PSU Cultists site directly.
