Corsair CX850M 850W Power Supply

Recently, we took a peek at the budget-minded Corsair CX750M. It turned out to be somewhat long in the tooth unit that didn’t hold up all that well against the competition. But what about the 850W model? Are all CX units created the same? It’s my intention to find out today.

Not too long ago, we took a look at the Corsair CX750M. Although it turned out to be not quite the bundle of mediocrity that many online forum users have been trying to use as a crutch to go all anti-fanboy on Corsair, I did find it to be more than a little lackluster when it came to competing in today’s marketplace.

Today, we’re going to look at another unit in the CX line, this time at 850 watts. The OEM did such a poor job of assembling my CX750 sample that I’m happy to give these units another chance. At this point I don’t have too high expectations for this unit, not when the CS850M is out there giving us better efficiency, but all the same I won’t be too terribly surprised if we have a better time with this unit than we did with the 750W model.

Like we saw with the 750, there’s some marketing on the back of the box. It’s the same marketing, in fact. Thermally controlled fan. Modular cables. Rather average in length three-year warranty. Up to 85% efficiency. None of these things are new to us unless we just got out of a stasis chamber having been frozen back in the year 2000.

I’m just going to skip right to the unboxing part now. The box has no marketing surprises for any of us, really. Take the 750W box and slap the 850W specifications on it, you get this box.

I don’t know about you, but the last thing I need is to look at cardboard and hype all day. So I guess I’ll turn off the parliamentary channel too while I’m at it.

It comes as no shock to me that the contents of the box add up to a power cord, some modular cables, a bag with some zip ties and screws, a warranty guide, a safety guide, and a power supply. We’ve seen the warranty and safety guide before, so I’m going to lazy it up some more and not bother to scan them. The actual user guide is, as usual, found at the Corsair site.
