It's been a little bit now since I last reviewed a Corsair unit, hasn't it? My last one was back in May, when I examined the CX850M, a unit that turned out to be a little underwhelming. Since then, my buddy Tazz took a look at the RM750i, a new Corsair Link enabled version of the RM series I haven't personally seen since they'd just transitioned from Chicony to Channel Well as their OEM supplier of those units.

You can imagine my surprise when I saw Tazz' review and observed that not only had the interactivity been added to those units, performance had seemingly improved as well. But was this an across the board improvement? I was offered the chance to find out with this here RM850i, and I took it. So that's what we're going to do today.

Of course, we're not going to get a review started without some marketing and box pictures, are we? High performance. Premium components. Low noise. No... ULTRA low noise.

All Japanese capacitors of course, because nobody could quite bring themselves to believe that a company known for high end server PSUs like Chicony could possibly know what they were doing with the Chinese capacitors. Pardon me for a second. Either my eyes are rolling or we're having an earthquake.

Naturally, the big deal addition to the RMi series is the Corsair Link functionality, first seen with the AXi series. While other brands do have software interactive power supplies, like the Thermaltake Toughpower DPS, Corsair Link aims to be a much more system wide solution helping you monitor and control more than just the power supply. I very much appreciate that, even if the software hasn't always worked very well for me. The bugs seem to have been worked out, and I haven't had any problems with it in quite some time, like those experienced with the AX1500i review.

What good is a power supply without cables? Not much good at all, I say. The box assures us that this unit does have cables, and these are the types of cables it has. We'll take a closer look at them on the next page.

80 Plus Gold. Single or multiple 12V outputs. Corsair Link. Japanese capacitors. Seven year warranty. Ooh, I like that last one. It's not the ten year deal EVGA has going on, but let's face it... ten years is really excessive, anyway.

It's time to do some unpacking. Corsair continues to pack their units in moving van size boxes, with lots of foam padding. No complaints with that.

Inside the box we have a warranty guide, power cord, bag of accessories, bag of modular cables, power supply in a velvet bag, and the latest novel by Stephen King entitled "Corsair."

No, wait, that's the user manual, not a Stephen King novel. Wait... I just gave him an idea for a bestselling horror novel, didn't I? Something about pirates and power supplies, no doubt. I want my cut of the take, Steve! Remember where you got that idea!

The contents of the accessories bag. Tons of zip ties come with this unit, as well as some screws and a case sticker.
