Corsair RM1000e 1000W ATX 3.0 Power Supply

Installed this unit twice with the fan down and the fan made a terrible rumbling noise both times, returned the first unit to get the second, then returned the second unit to get an EVGA G5 850W Installed this unit twice with the fan down and the fan made a terrible rumbling noise both times, returned the first unit to get the second, then returned the second unit to get an EVGA G5 850W

Returned this power supply.
I was not told if this was a fault or by design. But this power supply had constant high frequency hum.

Not an issue for gaming PC as GPU fans are will block off this noise, but if using PC for work on your desk you can hear it. Returned this power supply.

Maybe I'm just unlucky, but it seems to have happened to multiple people online.

This PSU has a high pitched coil whine like noise and it's unbearable. Maybe a quality control issue. Maybe I'm just unlucky, but it seems to have happened to multiple people online.

Overall it's just a PSU, it does what it is supposed to do; but it does it very well (note: I bought the 850W model, but they are all the same in looks and features; I have used it for 6 weeks at this point). It is completely silent under low load, and not noisy even under load; it is completely stable.
It looks nice for what it is, PSUs can only look a certain way, but it is cool and modern-looking (I appreciate that kind of thing even though it is hidden away at the bottom of my build as per most modern cases).
Please note that this model makes an audible 'click' when powering up and switching off.

Please note that this model makes an audible 'click' when powering up and switching off. It is by design and something Corsair even state on their website; it is nothing to be concerned about.
The cabling is fantastic (ATX 3.0, so the latest available) and it has a 7-year warranty; I'm looking forward to owning this for a long time.

Very happy with this Power Supply Unit (PSU). As a future proofing of my PC Build, this modular PSU has all the answers! I did a fair amount of research before deciding on the Corsair RM1000e. Very happy, and the price at PB Tech was far better than everywhere else I looked. Very happy with this Power Supply Unit (PSU).

The fan is the LOUD and it's the killer! When the PC is at idle it sounds like a single engine aircraft is flying overhead. I would return it if there wasn't a 30% egregious restocking fee.
