RM850X SHIFT is a nice PSU, it's very quiet. I was expecting a lot more time saved and easier to build with on this PSU but it really didn't feel much easier, I think the case you use will contribute more to that than the modular slots being on the side.It has a 12VHPWR slot for the newer graphics cards that use that, so you don't need to use the power adapter that came with the graphics card, just plug straight in which is appealing to me. That 12VHPWR cable was slightly higher quality and had a more rubbery/flexible type of sheath, the other cables that came with it are the standard hard plastic that isn't very flexible. I took a point off for those cables, they just feel/look bad.

Good bit of kit. The PSU is the powerhouse for your system so buy the best, buy Corsair with a lifetime guarantee.

I will preface this review by saying this PSU is very particular and will likely not work in every case. That being said, I built mine into a Lian Li Lancool 2 and it was an absolute breeze. Any case that has proper real cable clearance behind the PSU mount, this is an absolute game changer. I am running it with a 3070 and 3900x and so far it’s been whisper quiet and had no issues. It’s everything that’s great about the regular RmX series plus the new ATX standard and a much better position for the cables to come out of. 10/10 recommend with the right case, just do research or keep the receipt.

Well worth every penny. 850watts is a nice all rounder. Headroom even with my 2080ti and future plans for future GPUs. Great Value. Highly Recommend. Love the modular design and braided cables. Plenty of Pci-e cables and others .
The Corsair RM850x is a good quality power supply with enough connections for most builds and a 10 year warranty. Recommended
I absolutely love how this fits in the case with the cables coming from the side. Fully modular and the fan is quiet
Great power supply concept. Corsair RM series is always reliable and consistent on power. I bought this for the full modular side interface and It's definitely a huge plus for wiring and cable management. Because it's a side interface you'll want to check for cable clearance on the backside where all the wiring is hidden. The connections are also Type 5 so the connections going into the PSU are smaller and different that what most people have used in the past. Aside from that it was worth the extra $10 to have the side interface to me. It's also whisper quiet.
This power supply is great for all needs when building a pc
Had to return this one because it was a non-standard layout. I was dumb and didn't notice on the packaging that the modular power ports are on the side of the unit. This did not work in my 2U Rosewill Rackmount case. If I oriented this in the case, the ports for the modular cables would be facing down to the bottom of the case. Obviously this leaves no room to plug in the cables. Most PSUs have power in on one side and power out directly on other side. This configuration would probably work OK in most regular ATX cases. So pay attention to the layout of this one. I attached an image that helps show this point.
Really benefits the acoustics of a new system, almost silent with this product when using comp for non gaming purposes such as word processesing or general activities. It gives me ability to increase components in system over the next few years with no worries, with plenty of cables. Top quality product.
