Corsair rm750x PSU:This is not a review after this much time and so many reviews ... just an impression and a chance to show pictures of this unit:I bought this PSU a year and half ago for my build. It turned out to be my first and only component as pricing was so crazy. I was going to go amd 7600.But, as i have just finished my build now, i went intel 13600kf on an ASUS rog strix z690-E (pricing and compatibilty so much better now)I decided to use this corsair rm750x still because i am going to use my old nvidia rtx 2070 for awhile yet.But i was tempted to get the 12 v power connector version for the graphics card but heating issues disuaded me more. Plus, i did get this one for avery good price.SO much so that i will not upgrade the graphic power chords as that would be one third the cost of the PSU for the authentic corsair version.I am not a fan of the pig tails x 2 for the graphics. SO bulky. It was only with my extra wide lian li 216 case that i could fit them in.The two CPU cables were a challenge too with their long sleeves vs tight fit at top of case. Luckily i could remove the top of the case. even then... please see pictures.I went corsair PSU because my last one is still going strong after 9 years (hx650) no sound issues.I am very confident of the awesome quality of this PSU.I have not heard the PSU fan start up .. 2 weeks into the build now. dead quiet and cool :DI am very happy with this unit ... just not so much for asthetics (darn influencers as previously i only cared about performance).Please see pictures :)

I love this idea of 'shift' in the location where the cords usually go. This makes it so much easier for cable management since u dont have to unscrew the psu when u have to pull the cords out to reposition cords. Since when u screw in the psu, u can still access the side with cords facing you. Small difference in design but big difference when it comes to convenience. It is also silent and inaudible. There is no coil whine at all unlike the other corsair rm750 i had where it would have gentle coil whine sound even when the pc is not turned on. Silent, great cable management and powerful as it powers my msi slim 4090

i've been using corsair power supply since thier first Tx850W non modular that i still own and still work despicite it's age. i don't exactly remember but been more than 12years running 24/7 that power had more pc than most people would've done. so was about time for an upgrade and i got this RMX850 modular on a slight deal, and i wanted a modular after owning also the hx1000i for my other rig. well won't go back to non modulare that for sure.
Everythings was sealled, not a repacked open box sold as new pretty happy, everythings was in the box no damage or missing anything. super easy to install on most of any cases. the ONLY thing i'm not fan of is the cables sleeves they're not great and doesnt bend easy. otherwise still happy with my purshase.
Definitly can recomande this psu. doesn't make a lot of noise under load, and the fan won't turn if not require so this is a good silent psu!

Upgraded from a low tier supplier (Huntkey) to this just for peace of mind. It works exactly as expected and being modular helped a lot with my cable management.

As far as I am concerned Corsair make the best PC power supplies you can buy for the money, this one goes one step better with the Flex cable routing. No more trying to fit hand into tight spaces or having to unscrew power supply to connect power cables. Everything is completely accessible on the supplies side panel!!! Could not ask for more convenient and easy installation and setup...

I needed new power unit for my pc and this one was a good price for the wattage and it fits inside my case. It's got plenty of power and wattage to support anything and runs really quite, and it was easy to install and came with all the cables needed to hook everything back up. I would recommend this particular unit to anyone and the also the brand as well. It's quality is really good and run any pc for years to come.

Necesitaba hacer upgrade de mi fuente, pues adquiri una rx7900xtx... y con el resto de componentes que tengo, necesitaba minimo 900w, pues bien esta fuente funciona de maravilla tengo bastantes años usando fuentes y memorias de Corsair y al dia de hoy no e tenido ni un solo problema con alguno de sus productos.
Esta fuente tiene un diseño NOVEDOSO, pues las conexiones modulares, en lugar de tenerlas por la pate de atras, los tiene a un costado, si bien no para todos puede ser funcional por el tamaño de su gabinete, a mi me fue de lujo de hecho por eso la compre, y la gestion de cables fue mas facil en mi gabinete Thermaltake View 51.
Tiene conexiones listas ya para las nuevas tarjetas graficas y gestion de energia necearias para las mismas.
