Corsair RM850e

[Mista G]

@JonnyGURU - Noticed a new model of PSU here in the UK... RM850e.

 

What's the deal with this new model as I've noticed the warranty is only 7 years.

7 yrs is already pretty good in my book

But it's like cars, the more electronics you put into the less they last...

More compact size, uses a 120mm fan instead of 135mm, different manufacturer and design, cheaper non-Japanese capacitors, lower temperature rating 40°C vs 50°C on the RMx, shorter warranty. Marketed as being "Low noise" it's actually no better than the other RM/RMx units, scoring A- in Cybenetics noise testing which is the same as the RMx 2021 and worse than the 2018 RMx which is A+ noise rating. Most likely due to using a more compact design and a smaller 120mm fan than the 135mm fans in the RMx/RM units.

 

Basically it's just a cheaper fully modular 80+ Gold power supply from Corsair. It's AUD $40 (~$25 USD) cheaper than the RMx models here in Australia.

RMe seems to be on CXF level and probably the successor of CXF without RGB. HEC platform, Taipo caps, 120mm fan. Must be cheaper than RM and RMx.

Thanks for that very informative post. Do you know what has changed with the V2 revision of the newer RM850x?

The 2018 revision was the V2. There was another model before that. The 2021 revision is the third version of the RMx. They won't be labelled 2018 or 2021 on the box it's usually just how people refer to them to differentiate the different revisions.

I don't know the full changes off the top of my head and I'm about to head to bed, but I know they changed the enclosure and fan grill to update the design to match corsair's other recent products, swapped the rifle bearing fan for their maglev fan. Depending on the wattage some of the 2021 RMx have an extra EPS12V cable.

If you look up a review for the RMx 2021 on Tom's hardware or watch the hardware busters video they'll likely list the changes.
