Corsair CX750M v2 Power Supply

The Corsair CX series has had a rough road of it in enthusiast circles. Thanks to a low-ish thirty degree specification for full power operation and what was perceived as substandard capacitors, a lot of people have widely and unfairly criticized it as being junk when it really wasn’t. Corsair wants to change that perception and is reinvigorating the line to do just that. It’s a tough row to hoe… this is a bargain line of units, and you can’t make wide-ranging changes to it without driving the price up to the point people won’t buy it. Let’s find out if the new version improves on the old and yet still manages to keep things affordable.

Morning, folks. Today, we’re looking at a new old unit from Corsair. What do I mean by that? They’re refreshing the CXM line, that’s what. This most basic of the Corsair modular units has gained an unfair reputation over the years, and despite actually putting in a good showing of itself for us (though it did shut down in the hot box), Corsair haters pulled out their pitchforks and chased the original version all around the Internet. Excuses? They had a lot of them.

“It’s only rated for thirty degrees. It’s going to explode.”
“Those are Capxon caps. I heard those were bad. Besides, it’s going to explode.”
“You can get the BargleGargle Crazypower 800W for five bucks cheaper. Why buy that Corsair junk I heard will just explode?”
“Everyone’s buying Corsair. I hate fanboys. Here, let me go on a rampage against the one Corsair unit never intended for high level enthusiasts, so the fanboys suffer. Let me just set my shadenfreude to max, type the word ‘explode’ here along with some sciencey stuff I can’t really back up, and… beautiful!”

For the last time, Internet, there’s a difference between exploding and shutting down due to overtemp protection. Junk units don’t have overtemp protection… those are the ones that explode. Do I still think thirty degrees is unnecessarily low? Heck, yeah. But remember what I said – this is not supposed to be a top of the line power supply. It’s a budget unit. You want forty degrees? Buy one so rated, like an RM unit.

Or… oh! This new version of the CXM! Corsair must have gotten fed up with the naysayers and updated the design to shut them up. We are now good for forty degrees, people.

Along with an updated unit comes a new box. One far more attractive than the old white and green box, in case you need an easy way to tell the two revisions apart. Black and yellow? You’ve got new juice, there, fellow. Tangy and brown, you’re in cider… no, wait, that’s from the Simpsons. Green and white, it’s the old one all right.

Much of the marketing is the same. The unit is targeted toward people who need decent power on a budget, as evidenced by such cost-cutting measures like only semi-modularity and 80 Plus Bronze. The challenge with units like this is cutting cost without cutting too much performance, and I thought the original did a pretty good job of that. Though, again, thirty degrees at full power was too much of a compromise. But that is seemingly no longer an issue, so I’m looking forward to load testing this one.

Cables? This unit has them. Unfortunately, it looks like we may be dealing with hardwired Berg connectors, so I’ll get my red pen out now.

There’s really not much one can do to spin 80 Plus Bronze as a marketing point anymore, but the box does its best. Really, though, in these days of 80 Plus Titanium, it’s easy to forget that even Bronze is still pretty good. When you think about it, for most people the cost differences between Bronze and anything better than that often can’t be made up with the difference in the power bill over the next few years, so that’s really no good reason to get anything more efficient.

No, if you want a good reason for Titanium, toss the cost argument and try the “saving the planet” one instead. It makes so much more sense.

There’s marketing elsewhere on the box, too. Nothing we haven’t seen before, mind you. I think I’ll unpack, now.

We have a power supply, modular cables, warranty guide, safety guide, power cord, and a little bag with some zip ties and screws. I can’t say I really find this unit wanting for goodies – basic units aren’t expected to have a ton of little doo-dads like case stickers packed with them.

The user guide can be found online at Corsair’s site, of course. This has pretty well been the norm for them for a while now.
