Corsair has announced a new color option for the RMx series power supplies, Arctic White. Readers with a watchful eye may remember that a while ago the company brought out a special edition of the RM1000i PSU in white. Now by popular demand, Corsair has made this a standard option for two of their PSUs, the RM750x and RM850x. 

The newly redecorated power supplies are otherwise identical to their existing black-painted counterparts. This means they have fully modular cabling which can minimize the amount of wires users need to use, and see, in their cases allowing for a cleaner look. The cables come already individually sleeved in white with black connectors using three layers of paracord for each. Also something of note, one will find in-line capacitors on the ATX, EPS12V, and PCIe cables which Corsair says helps reduce ripple and noise, and improve voltage regulation.

Features of the RMx series include a Zero RPM Fan Mode, where the rifle bearing 135mm fan sit idle during light to medium loads, only spinning up with heavy loads or at a specific temperature. On top of that The RMx line carries an 80 Plus Gold certification for efficiency, uses 100% all Japanese capacitors rated to 105C, and provides owners with a long 10 year warranty.

The Artic White versions will fetch a $10 premium over the traditional charcoal/black RMx models. They are priced at $149.99 for the RM750x and $169.99 for the RM850x at the Corsair Website. Finally, Corsair is also stating that at least for now, this is it for white RMx PSUs; there are no plans to produce the lower wattage RMx series power supplies in white.

    150W is a lot of power on the legacy rails, has Corsair said anything about why they're putting extra large DC-DC converters. I checked the last 10 articles tagged with PSU: Most were 90/100W of 3.3/5V, of the two that were higher one was a 1200W monster. The second was a normal size but being only 80+ Bronze was probably an older design.

    Because then they would be 690 and 790 watt PSU's and they wouldn't be able to charge as much for them.

    Nope, that's an obsolete design you're thinking of. These're pure 12V models. Total rated power is out on the 12V rail, and the 3.3/5V is made from it using DC-DC converters. Every watt of power at delivered lower voltage is a watt less of 12V available.

    Derp. Know what you're talking about before commenting. The actual spec table is in article showing the +12V capability.

    For legacy support. Much for the same reason 20+4-pin connectors are used still.

    Are customers trying to keep old boxes running longer really the same market who're after PSUs with flashy looks though?
