I like that this Corsair has one large fan, instead of the two small fans on the Enermax. And since it generates less heat, the fan only comes on when it is needed (very quiet). But I do wish there was a button that could turn the fan on a low RPM speed just for extra ventilation.
So far in the month that I've been using it, I've had no issues. The first 3 weeks I've left my PC on 24x7 just so the new power supply would stay on, and see if any problems happened. Then the 4th weeks I used it as normal, turn system on and off as needed. I'm not sure if I'll save any major money on electricity using this Gold rated supply over the 12-year old Enermax. Also, the Enermax 12 years ago was about twice the price of this current Corsair unit. I just hope the Corsair lasts and is reliable.
1. There are NO 8 to 6+2 single pcie cables. It only comes with 8 to 6+2 DUAL pcie cables. So I have two unused 6+2 connectors hanging out under my GPU.
2. The cables do not bend much at the ends. There is a (maybe excessively) large piece of heat shrink at the end of the cables which make them difficult to manage. Instead of curving under the gpu, they stick out so far that they almost touch the window. The 24 pin sticks straight out far enough that it's almost a 90 degree bend off of the motherboard connection and another to get it through the cable management slot.
I'll be ordering individually sleeved cables soon. Aside from the cables it seems to be a very good PSU for the price.
The all-black cables look really nice and don’t clash with other aesthetics like ketchup & mustard cables on a lot of other lower quality PSUs do.
This comes with plenty of cables and I’m not using most of them but it’s nice that they are there.
I also think the little bag of zip ties they throw in is a nice touch. I actually ordered a bag of zip ties with this because I didn’t know it came with them and I didn’t even use them because Corsair had me covered.
All in all this is a high quality PSU with 80+ Gold certification and 850W which is more than enough to handle almost any system build that a normal, everyday computer will need. It will definitely future proof your system as you won’t have to replace your PSU for a LONG time.
Corsair also has a very nice 10 year warranty on this PSU which just goes to show how much faith they have in the quality and durability of this product.
First off the cables are horrible, extremely stiff and hard to bend in to position, i had to force Bend them for it to fit in the case, now they sit there looking like it has a huge strain on it This is especially worse in a normal mid sized atx case which is what I used. My case is the nzxt h500
Secondly, where is my friggin power adapter? What kind of company doesn't send a international power adapter to international customers (p.s I live in NZ). Now instead of being able to use my brand new 5k setup when I'm full of excitement wanting to watch 4k adult films and play fortnite at 240hz, now I gotta wait the next day and go into town.
I'm a busy guy, time is money!
Step ur game up corsair
Or should I say notfair.
Simple install and modular vs not is night and day. My cable management was incredibly difficult with my old PSU with all those unused cables.. This is my third Corsair PSU and I am happy with the purchase and it came with everything I needed
The stiff cables and restrictive tape made the installation a lot less clean than I would have liked. The electrical tape wrapped around all of the connectors prevented me from tucking many cables to my case and created a weird flex to the cables as well as making it look pretty cheap. Probably going to have to buy different PSU cables to get the cleanliness that I would like.
But if you're not as anal, I highly doubt, then this product is fine. It does what it's made for and powers all my components well.
Much cleaner look, the cable skins are nicely done.
I'm pretty sure the fan never runs on this unit, it will fire up and spin during boot, but if it does run during normal use or full load, it's at a low enough speed to be inaudible.

Tonight, I was browsing web and PC turned off on me leaving only my RGB ram glowing.. Tried to boot and nothing was working. The only way I could force a start was to use a screwdriver with the 2pins of the power switch. My RGB ram would lighten up but nothing else.
I stripped everything to make sure it wasnt a component. Only CPU power and mobo power was connected. Nothing happenned either so I pluggued in a cheap PSU I had for years like in the photo and PC booted fine. Its probably badluck PSU. I have faith in corsair quality so thats why I didnt give a 1 start review. I will see once my replacement arrive.
The fan doesn't even run half the time unless I'm gaming and then it's loud anyways from the gun sounds. Overall I would say this thing is an absolute beast, probably overkill for my build but hey, room to grow.
Since then I've been using Corsair PSUs and I couldn't be happier with their performance. I have a Corsair HX850 as my original modular PSU, so when I went to build my new PC I picked up this RM850x model. It's fully modular, it's whisper quiet, it isn't too long, and it has all of the connections you could want.
But what sets this unit apart is that it comes with TWO CPU connectors! So you can hook it up to a motherboard with an 8pin and 4pin connector for the CPU. If you're doing any serious overclocking with an i9 or Ryzen 3900+ this is absolutely the PSU for you.
The only thing I don't like is how the connectors have this extremely stiff wrap near the actual plug ends. While you can still do a clean cable build in a case, these stupid stiff wraps will prevent you from being able to twist or curl the cables so that they aren't sticking straight to the side for a couple inches before going back to being a regular cable. Why they chose these stupid wraps I'll never be able to guess, but they unfortunately exist.
If you're using the stock cables this unit is a 9/10, with the point loss for those ridiculous stiff wraps. But if you're going to use cable extensions or aftermarket cables then this unit is easily a full 10/10.

Installation was painless. As I was replacing another still functional but less powerful power unit, I just made sure that whatever I unplugged would be plugged back into the new unit.
This power supply might not be the cheapest there is, but I though it was well worth the price in order to protect the expensive motherboard, CPU and video card that live inside that computer.
Mi única queja es que los conectores podrían tener un mejor sistema de anclaje (entre ellos cuando se pueden dividir) y las terminaciones tienen un forro de plástico poco flexible que hace el acomodo y manejo de cableado un poco difícil.
Sin duda es una buena solución a fuentes de alimentación y tiene una alta eficiencia.
It doesn't have a modular 4-pin power plug and normally I'd take a star off for that but everything else about this power supply is so great that I would have given it 6 out of 5 if I could.
Now it's been roughly one week of PC usage and the power supply just died on me I unfortunately can't get a refund anymore and it looks like I will have to go to Corsair for theirs support which we all know sucks I'm already on case with them that has been lasting for 2 months.
It's a shame that such a high end company can't even provide products that are stable enough to not break. EVGA's support is great from what I've heard looks like I'll be switching to them.
