Hi all! I can buy for same price - 110euro: Seasonic Prime W 750 Titanium or Corsair RMi Series RM850i 850W Gold (both used and with long warranty 8 years, both in perfect condition). Which one is better and why? Please recommend me one of them but explain your recommendation. I mean.. Please justify your recommendation.

Well, they both aren't in perfect condition since they both are used.
As in brand new, Corsair unit comes with 10 years of warranty while Seasonic unit comes with 12 years of warranty.

In any event, here are two reviews for you to read;

I, personally, would go with Seasonic unit since PRIME series is the best offered by Seasonic and it's also the best PSU money can buy at current date. That, and Seasonic unit also has the highest efficiency there is (80+ Titanium) while Corsair unit has average efficiency (80+ Gold). For the best offered by Corsair, you need to look towards AXi series. And while Corsair unit has extra 100W max output, in singe GPU setup, there is no need to get higher than 650W PSU.

In fact, i've already gone with Seasonic PRIME 80+ Titanium PSU. I have the 650W unit powering my Skylake build, where's my other 2 rigs, Haswell and AMD are also powered by Seasonic. Full specs with pics in my sig.

There can be only one.....and it is the Seasonic Prime...This is probably one of the best PSU's on the market with a stellar efficiency rating and built extremely well buy the actual vendor itself. It has also been reviewed by Johnny Guru and many others and usually tops all metrics..

Especially if second hand, i'd go Seasonic.
