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.

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.
