Corsair RMx Series 850 W (2021)

Except every time you look inside your case, you will see those ugly 6+2pin piggy tail.
Besides, aren't those piggy tail cables dangerous to be used on high power GPUs?

They are cheaper because Corsair can use less cables for same amount of PCIE connectors.

Doesn't literally everyone else including Seasonic piggy-tails their PCIe cables ? I'm all for PSU manufacturers to stop doing that because if you really need two PCIe power connectors for your GPU then you most likely should use two separate cables powered by separate outlets on the PSU anyway, but that ain't gonna change because people are stupid.

Oh, cr*p you're right lol
I thought all Seasonic PCIE cables are one connector per cable. Apparently only PRIME series are bundled with this kind of cable.

Thinking about it now, it is disappointing they didn't went with flat cables with this refresh especially since the RM 2019 had flat cables.

I myself have no problem with in line caps but seeing how people complain about them and the fact that most new PSUs comes with flat cables now it would have been preferable to include them

My Prime PX-750 has three separate PCIe cables included, no daisy chain, but it does have the 6+2 piggy tail which I honestly don't mind. Using two cables to power my 3070. Considering how much better it was to route these cables compared to any of Corsair's cables, I'll take it. No dumb inline caps either.

Thanks for a very in-depth review with great pictures and content. You and Wizzard are masters of your craft

Thank you!

First comment i had to make and account to said this: Can someone please explain why the 2018 version comes with 3 PCIE cable a total of 6 PCIE connectors and 2 cables 8 pin for the CPU and the 2021 version comes with 2 PCIE cables a total of 4 connectors and 3!! 8 pin CPU cables when i saw that i was like what kind of motherboard would need a total of 3x8 of power??! MAYBE is a mistake? and a youtube video from Corsair Spain was reviewing the new PSU 2021 ver and he said you should try to avoid connecting a graphics with 2x8 connector with one cable of the PCIE ( daisy chain ) because of the new graphics card. So my question is what about the 3080 custom cards or the 3090 that requires 3x8 the 2018 you could use 3 different cables and now your stuck with 2 how can you even manage the future with 2 only PCIE cables from the 2021 version when the 3090 Ti/Super comes out in January there saying is going to utilize 400-500w So that means using 2 cables will not work unless you risk losing the PSU cables or damaging the graphics card and the people having the 2018 are safer because you got a total of 6 PCIE connectors so when the new graphics card in 2022 code name Ampere requires 4x8! your safer with 3 cables than with 2.

Because nVidia wanted to use EPS connectors for their 12-pin adapter at first to make sure that people wouldn't try connecting it with 6-pin cables which wouldn't hold up and the GPU would have no way of knowing that it's connected through adapter using 6-pin cables (the +2 part of 6+2 is there to tell the GPU that it's the new, improved cable standard, it's not technically needed as +2 part doesn't provide power, it's better 6-pin connector itself that's rated for higher current). But then they changed their mind to use 6+2 after all. Corsair RM-x 2021 was in development just at this time, and it was too late to change the project so they kept it as is.

Wait i am confuse the 2018 version does have or doesn't have EPS connectors? As far as i know both of the versions have 6+2 cables so don't know why you mention.
I got (the 2018) version and now i don't know if to return it for the new version or if am better of with the (2018) because of my graphics card connectors.
My question is, is it better to connect a graphics card that has 3x8 connectors with 3 individual cables or daisy chain the thing with 2 only cables that the 2021 version comes with??? what version is more future proof as well the old one or the new 2021 one. I wonder is Corsair is ready for this : https://www.tweaktown.com/news/8231...s7VoA3oAZl4Ry4yTBH70WpI-Ia-fbpAUxgR5Dq36r7vPU

Because i never mentioned the 6 pin justg the normal PICIE 6+2 connectors in total, you can call it the Pcie connector but that doesn't refers to the point.

Ofc it does, but 2021 has more of them because they were also supposed to be used to for supplying power to the GPU.
3x separate cables is obviously better but 2x should do it. No idea about RTX3090 Ti or Lovelace tho, i'm sure if you would have issues with your PSU and would yell loud enough at Corsair support they would be able to send you 3rd cable. But if you already have 2018 version, why change it to 2021 then ?

I live in a place where the power goes out alot and i have lost 1 battery backup and 1 PSU already. I really liked the Corsair 2018 because seems to be strong so far and kinda was thinking that in the future if i ever needed to get another one. So i am not sure right now if to buy another 2018 is on sale for $111.99 or just stay with this one and in the future get the 2021 version but the problem is the 2xPCIE cables. Maybe ill build another pc as well not so sure, but is kinda a bummer that the new version has 2 not 3 like all the 850w PSU even some 750psu has. At the end do you think the 2021 ver is better than the 2018?

How does one get the 2018 version? That one seems more quiet. Does it say 2018 on the box?
