Good day to you, power supply fans of the Internet. Today, I'm looking at a unit from Corsair, the CX750M. An 80 Plus Bronze affair, this is a budget minded unit that promises decent performance at a low price. We don't often get units like this from Corsair, but we have one today and so I'm going to put it through its paces to see what it's made of.

Elsewhere on the net, there was quite the hullabaloo over this platform when a certain website tested the non modular version of this unit and it ended up not doing so well. Me being the curiously insane type of humanoid, I'm especially anxious to see how this one does for me when I test it. Will it perform like that one? Has Corsair started a long, slow spiral of doom? Was that other one just caught on a bad day? We're going to find that out today.

Like most power supplies, this one comes in a fancy box with some marketing. We have a modular power supply, as the front of the box already told us. Low noise, thermally controlled fan. Cables. Connectors. 80 Plus Bronze efficiency. All this stuff is pretty much standard fare for units like this.

Corsair offers a three year warranty on this unit, which is a big step down from the lengthy warranties on their top end products, but still pretty much the industry standard for anything half decent. I only really start to panic when I see warranty terms drop below that, like the two year deal we saw with that Lepa.

On another side of the box, we find some compatibility information and a chart of where this unit fits into the Corsair product line. Which, quite frankly, has become confusing as hell. As you can see, the CXM and CX are way down at the bottom of the scale, so the implication is that this is as bargain basement as it gets from Corsair.

I have at least two other Corsair units in the lab right now that aren't represented in the chart here. They belong to the CS line, which is apparently a bit newer. On their boxes, the chart shows them above the CX units, which only makes sense for those 80 Plus Gold units. Gold is better than Bronze, right? Well, it depends on the units in question.

Say, remember my CS550M? It's been in use since I reviewed it, powering one of my backup mining rigs. I use that rig whenever the main mining rigs are full and I have one video card more than I have space to put it. Before that, it was powering my office rig 24/7, so I have some idea on how the CS line, the next line up from this one, holds up over time. The verdict? Electrically, it's as solid as the day I reviewed it. However, the fan in it started making noise last week, and I had to replace it. One year... I got one year out of the fan it came with. That, folks, is why I don't care for sleeve bearing fans. Odds are most of them hold up better than mine did, but I'm still going to score them as I have been. Does this unit have a better fan than the next model series up did? I don't know, but... I'm getting ahead of myself, here.

It's time to do some unpacking.

We have a power supply, some modular cables, a power cord, some accessories, some documentation, and one of those silica gel packs that you're not supposed to eat.

The accessories bag came with some zip ties and some screws. No complaints there for a bargain unit.

On the documentation side of things, this unit comes with a warranty guide, seen here...

And a safety guide, seen here. No manual... you're supposed to seek that out online. And this time, Corsair does actually have one available, but it's lacking in specs. You need to get that from another document at the Corsair site, so I'm thinking I'll be scoring a modest deduction later. Nobody likes to go through one document only to find out you have to go find another one for the info you want. I remain a little on the fence yet about not enclosing a printed manual with the actual unit. As long as one is easily available, I don't mind saving some trees now and then. Especially on a budget unit.
