* Do note that the 7 year warranty is a substantial 40% upgrade from the earlier RM non-i series.


Corsair famed PSU insider has this to say about the improvements...
jonnyGURU forum post

"The RMi is more like a Gold HXi than an updated RM.

The similarities:
  • 80 Plus Gold
  • Fully Modular
  • Zero RPM mode
  • SP135 fan
  • LLC Resonant Mode topology with DC to DC for the non-primary rails

The "upgrades":
  • 7 year warranty vs. 5 years
  • ALL Japanese  capacitors, including solids
  • Rated at 50°C vs. 40°C
  • FDB fan vs. Rifle bearing fan
  • Digital Link output allows for more monitoring and control than RM

If/when RM gets "updated" across the board, it's just going to get all Japanese caps and will probably lose Link to reduce cost."




My sample unit from Corsair USA...

Note the presence of the reinstated (and updated sharper) Corsair sail logo on the packing box, newly introduced on 1st June 2015.

Safely packed inside....






New B & W colour combo! 

Again, the prominent angular Corsair logo to show that this is their newest PSU series.









Bundled goodies!

Note the Corsair Voyager flash stick comes only with press review units and contains a very long and detailed report for the tests this particular unit has undergone.

Corsair Type 4 PSU Cables

Hmm, wait a minute... don't ever remember seeing Corsair Type 4 power cabling before, let's try to find out more about them...

A few comparison photos - the Type 3 main ATX cable is positioned above Type 4 and both are shown individually against the RM850i in the latter 2 photos to demonstrate the pin differences.






Custom Corsair PSU cable users for the new RMi series should take note and bear this disparity in mind whenever swapping PSUs.





Type 4 Cable Info

OK, here's the official word from Corsair veteran, Aaron Neal, Global Product Manager PSU. Also a shout out to Ms A.L for the info link up, a big thank you for your ever ready help.

  • Type 4 cables are new for the RMi series. 
  • The biggest change between Type 3 and Type 4 is on the ATX 24 pin where we have added more sense wires making the DC connection on the PSU is 28 pins instead of 24. 
  • The type 3 ATX cable will not directly plug into an RMi PSU without modification. 
  • The rest of the cables, although labeled Type 4, are the same pin out as Type 3.

So there you have it straight from the guys at the source!
