The new RMi series from Corsair is a bit strange and confusing for some so i am going to make a thread that explains everything so there wont be anyone that misunderstand.
The first one is the name itself RMi and the newer RMx, anyone not knowing any better will just think this is the old RM with a new name or an improved version or something.
You would be very wrong to assume any of this so i am going to make it as clear as i cant so there wont be anyone that will misunderstand, the RMi and RMx series have nothing zero nada zip zilt to do with the old RM series.
It is in fact quite surprisingly a modified / upgraded / improved version of the older Corsair HXi series just with downgraded efficiency.
Wait what would you might be thinking thats pretty strange and yes i agree.
So i am going to compare the two and show you how its been improved and why you should get the RMi instead of the HXi.
Another thing i like to talk about is the fact that the cables on the RMI / RMx series are new and Corsair calls these cables type 4 and the reason for that is the fact that the 24 pin cable is new and WILL not work with the older type 3 cables.
This means that the type 3 aftermarket cables that Corsair sells WILL NOT! work with the 24 pin on the RMi / RMx the reason for this is the RMi / RMx uses a new 28 pin cable at the PSU end so type 3 and 4 cable wont work with each other.
If you remove these caps or replace the type 4 Corsair cables the ripple suppression WILL go up (15-35mv) so please dont remove them or use type 3 cables on the RMi / RMx it will make your PSU worse.
The last thing i want to point that many might be thinking is well the HXi 80 plus platinum rated and the RMi / RMx series are only 80 plus gold rated so the HXi must be better right?, well wrong again as 80 plus has jack to do with quality rated output stability or anything its an efficiency rating system nothing more.
80 plus is pretty much irrelevant so with that in mind there is no reason for you to buy a Corsair HXi at all its rather pointless now as the RMi / RMx is not only better its cheaper as well.
Anyone with a working brain can figure out there is no reason to pay more for something that is worse so with that in mind i am going to say that if you want a Corsair unit despite the fact that the EVGA SuperNova G2 and P2 series are about as good and about the same price at least get the RMi or RMx instead of the HXi.
My opinion is the RMi / RMx series are the superior series compared to the HXi series despite the lower efficiency.
Corsair RMx explained
The brand new RMx series is the same PSU as the Corsair RMi just with all Corsair link removed so the price can be lowered, other then that they are pretty much the same series.

HXi
RMi
Looks pretty much the same
Quote from techpowerup about the RMi
This is actually a HX1000i with some component changes that lowered efficiency a tad while boosting performance everywhere else. The RM1000i, for example, not only uses exclusive Japanese capacitors and has much larger bulk capacitors (1150uF combined capacity vs 940uF of the HX1000i), which will significant increase hold-up time. We don't know the actual reasons behind these changes, but Corsair made a point of further improving the platform in some rather crucial areas, which is very strange considering the RMi line is situated below the HXi series.

HXi 12v rail
RMi 12v rail
About twice as good voltage regulation on the 12v rail on the RMi compared to the HXi
HXi 5v rail
RMi 5v rail
HXi 3,3v rail
RMi 3,3v rail
Again the RMi is far superior to the older HXi series on the 5v and 3,3v rails

Agian the RMi proves its better with lower ripple on the 12v rail
