There are several reviews on Amazon mentioning that the fan on this unit is loud and undersized. Also several noting a failure around the 1 year mark with very little help from the manufacturer. 🤷 Play at your own risk.

Bought one as a spare. I haven't had a PSU fail in about 20 years so no idea why I needed a spare, but that's SD for you.

Thanks OP!

Nice! Been needing an upgrade. Good timing.
Surprised that MIR is at Amazon. Normally Newegg only.

I believe the PSU Cultists give this PSU a C grade. C may not sound great, but I think they are particular about A and B grades. At least this isn't an E (Avoid) or F (Replace immediately).

You speak my language... I checked how much I would pay for a PSU today to replace a sudden dead one... and in about 5 minutes I decided that having a spare for $30 it is not a bad idea!

Now the question is, how onerous is their process, how many denials to expect.

... mmm This one or the 550W for $21 after MIR.
It would be spare for me too, so can't justify a 750W which I never needed.

Nice price but still a no-go with reviews like this:
Quote :
Had an annoying rattling on my new build and finally tracked the source down to the PSU. The PSU fan rattles / vibrates every time it starts-up.

With the semi-fanless feature, the fan spins up about every 10-15 minutes and you hear a rattle or as some reviewers described it a gurgle or crackling sound. I wish I had tracked down the source of the noise within Amazon's return window, based on other reviews this seems like a common issue with this PSU but it's buried in semi-positive reviews.

Sound aside - it was easy to install and seems to be delivering power consistently but I would not recommend buying this unit.

It's a nice price, but I have to admit I'm not a fan of how rebates are starting to pop up again.
