Corsair RM850x (2018) power supply review

We review the RM850x power supply from Corsair. This 2018 update for the RM series now is offered in a silent RMx series that comes with 80plus Gold certification, that means it's 90% efficient at 50% load. Efficiency matters. The PSU itself is fully modular, for most of you with a side panel window in their chassis a must really as you'll want modular cables.

10 years of warranty shows trust in their own product!

they actually make them with top of the line japan made caps and stuff so they are a bit more expensive, as much as some platinums with short warranty
in the other hand there are some seasonics with 12 years

I cant get HX750i to start spinning at default profile either. And so while fully passive it only goes to 45 Celsius with system fully gaming loaded (cca 300W). I LOVE IT
With the 850W model we tested, up-to 340 Watt the fan doesn't even spin, and I can tell you that a modern age PC with a modern graphics card will likely not even reach that value.

I'm glad to see Corsair extending their warranties on their more mainstream PSU's as they are usually in stock at my local Best Buy. I have an EVGA with a 10 year warranty and its a good thing too because I am actually in the middle of an RMA on it as it is suffering power fluctuations atm and I purchased it back in 2013

Been using my Corsair TX750 for over 5 years. I think it is 82% up to 100% load so not too bad to be honest. It is still going strong. Good products.

Hilbert, what's your opinion about computers that are on 24/7 and are doing something (slow) in the background all the time, like a media server/file-server and/or providing some other services without a videocard (for example, command line game servers)
Would the move beyond bronze/gold make any sense in that case ?
Most of these modern PSU's are very efficient at 50%, but what about at 20% ? isn't the difference from Bronze/Silver to Platinum more noticeable ?

If it is idle most of the time , not worth it , that is also reason why you don't have platinum or titanium models below 600-700W it simply is not worth it , HTPC and similar devices that are using up to 200-300W are loosing so little power due inefficiency ( maybe up to 5W total) that is not worth the trouble and expense to go with higher efficiency PSU.

This is a lot.
My HX850 had 8 years warranty and became unstable after 7 years. I contacted Corsair, explained them an issue and they sent me new HX850i PSU.
Having 10 years insurance is pretty good.
Just reminded me to look at how old my HX650 is and turns out I got it in 2010 and it had a 7 year warranty... and.. it's still going strong.
Corsair make pretty darn good PSU's

was a bit confused when i saw this review, as iv had this psu with the 10 year warranty for around 5 months now in the uk. im presuming its the same model?
also the first page mentions corsair link capability, but this one doesn't offer it afaik.

It seems to be different dimensions of the PSU itself as well as a different connection layout and cables
Also the only mention I see of link, is in your comme

Corsair has been making really nice/reliable (higher end) PSU's for a couple of years now, they mostly use good components, and they give out long warranty's which shows their confidence in the products they make.
No issues with my RM1000i in about 3 years now, has been swapped around in different PC's and setups, never an issue
