Johnny Reviewed this unit and yeah it's ok. Older unit GX ii Pro 750w. Actually something Decent Coolermaster did, Absolutely.

one bad thing about the Corsair RMx & RMi : they have 0 fan mode which you can't disable

which means on load & medium load, fan doesn't spin

they pretend it's for noise but truth is no one cares about the noise PSU's make (which is low anyway)

and 0 fan mode is dangerous:

causes PSU to heat up over time (even if it's just moderate load) = shorter lifespan = planned obsolescence


also PSU fans are usefull they act as an extra exhaust for the case so indirectly if PSU fan is off then case temp will be a bit higher


again there is ZERO point in having 0 fan mode on a PSU


on Seasonic at least, you can enable hybrid mode (force the fan to spin even on low load)

Ran a Seasonic X-760 (KM3 Gold) on 0 fan mode for 6 years with np (with a couple of 28-36 degrees celsius summers with that temperature as room temperature), sold it to a friend and it's running in his pc for what's now 8 years total with only moderate coil whine.

I'm pretty sure it's gonna pass 10 year mark on 0 fan mode, so yeah if it has good components and is rated for ~50 degrees celsius operation what you said is not going to happen at all.

And plenty of us do care for PSU noise, it's not that important if it does have 0 fan mode or not, a 600-800 RPM fan of good quality is gonna be inaudible, what's more important is the max RPM of the fan, and how good the speed curve is. And RMx have the lowest max rpm fans together with the original Superflower Leadex I platinum and the Aerocool Project 7.

for those with their PSU on the bottom of the case maybe (but those I avoid & many others do)

but if the PSU is at the top of the case then case heat reaches it, and PSU fan can be useful to exhaust the air out of it

there's several on Corsair forums who say their Corsair becomes too hot to touch for more than a few seconds in summer even if the PSU's on medium load because the fan won't spin

long story short IF the PSU's at the top of the case (like in most cases) then passive PSU's should be avoided like I said it raises not only PSU temp but also case temps (especially is poorly ventilated cases eg. mine is an Antec Sonata 2 so I can't risk putting a passive PSU in there especially since there's already a gtx980 & a hexacore CPU in there lol)


and noise? quality PSU fans make insignificant noise compared to CPU or GPU fans so who cares tbh


best choice is semi-passive (hybrid) PSU with low-fan mode on low & medium load (with a switch to enable 0-fan for those who like this despite the risks). Seasonics have those iirc

the very fact Corsair didn't include a switch for passive mode for their RMx & RMi is suspicious

Top of the case? what era do you live in? almost no new case in the last 10 years have had the PSU in the top so are you a dinosaur or what?
Claiming the PSU is in the top in most cases is simply false unless you still live in 2008

Many avoid cases with the PSU in the bottom what? thats even more nonsense
Sure a few might do that but your claims sounds completely ridiculous or that you still live in 2008

I aint changed my case for the last 8y iirc but I dont need to (towers more expensive today anyway)

but serously why have the PSU at the bottom of the case - to have dust settle in the PSU?
or just cause manufacturers say it's trendy? (fashion trends lol)

Huh? How would dust settle in the PSU just because it is in the bottom of the case? When mounted in the bottom, its innards are not exposed in the case. It is there so it can pull in cool air from under the case and exhaust it out the back. It is easier to install because it rests on the bottom, and the case is more stable with it there.

? you mean the PSU is at the bottom and the PSU fan faces downward ?

in the low-PSU cases I seen the fan grid faces upward
like this one :

(read about some poor sod who had a screw fall into his PSU when unmounting his graphics card & he didn't even realize it until...^^)

ok so if the PSU grid faces downward then no risk of anything fall in - but then there's another problem how does air get in? the fan's too close to ground so not enough space for air to flow into the PSU
