It's that time again, peoples... another power supply is about to get reviewed. This time, we're looking at the Corsair RM650, a new unit in a range of power supplies optimized for efficiency, silence, and full modularity. Coming with a five year warranty, this little guy is certified 80 Plus Gold and comes with the nice bonus of being Corsair Link compatible.

You may recall that Corsair Link was first seen by us in the AX1200i and AX860i, wherein those units were able to be monitored from and even somewhat controlled by software. It's not too likely that this unit would feature the control abilities those other units did, more likely we are restricted to basic monitoring of things like fan speeds only, but even so this is a nice feature to include.

As is normal, the box has a lot of marketing on it. Among other things, this part of the box tells us that Corsair Link will be monitoring fan speeds and 12V current only when used with this unit. It also explains that the fan has a semi-fanless mode, which looks to be non defeatable, for silent operation. I'll try to indicate where the fan does or does not run during my load testing, but as usual when units are locked in the hot box I often can't see the fan. We'll have to wait and see whether or not this will be possible.

Meantime, it'll be easy to see where it turns on in cold testing, so at least I will have that data for you.

As we move the box around, we find yet more marketing. This side of the box tells you all about the modular cables.

Here, we have some compatibility information about the unit, as well as a chart telling us where the RM series fits in with all the others. You know, I never did figure out what all these letters stand for. AXi obviously stands for Artistic Xylophone Interference. I guess AX would be Amazing Xenon. HX is probably Hiccupping Xena. RM? That's obviously Ridiculous Mushroom.

I just wonder how this unit will perform in comparison to units in the Gravy Sauce or Crazy Xerox line. Or even the upcoming Chewy Sandbox line.

I'd say this is a good time to unpack stuff, so let's get to it.

We have a power supply, some modular cables, bag of goodies, a power cord, a warranty info booklet, a safety info booklet, and a solutions guide.

The warranty guide is a pretty simple affair, so I won't bother showing you what's inside.

Ditto the safety info booklet. All it does is tell you how to be safe around your new power supply, and direct you to the website to get the full user guide.

But there's a problem... there is no user guide at the site. There is a generic spec sheet for all Corsair units, but no actual user guide. Since the spec sheet is there I'll probably go a little easier on Corsair for this than I otherwise would, after all the spec sheet does tell me what I need to know to load test this unit, but when you tell me to go to the website for the manual and that manual isn't there, I get annoyed. I will have to score against this later.

And what's especially annoying about the lack of the user guide is the fact that they took the time to kill a few trees to market the rest of their stuff instead. This is the solutions guide.

Here's what's in the goody bag... a big pile of zip ties, some screws, and a case sticker. Nice to see a company not skimping on the zip ties... some of these power supply vendors treat them like they're fifty bucks each to make, or something.
