Page 1 - First Look

As you can tell from the above picture, I'm working on a review of Corsair's brand new Texas M series of units. At least, I'm assuming that's what the "TX" is short for, because if it's short for "tax" instead, I'm not cool with that.

Over time, people have been pestering Corsair. When will they start offering the budget oriented TX series in modular? Well, the day has arrived. The moment is at hand. The mustard has been cut. The bull's horns have been grabbed. I'm looking at just such a unit today in a 750 watt variety.

Along with the new modularity, this unit also brings 80 Plus Bronze certification to the table. We'll have to see how well this unit does with that by and by. But first...

Box pictures. You and I both know one of my reviews wouldn't be the same without looking at some cardboard, so why change things now? There are some bullet points to tell you about, so here you go:

  • The right blend of performance and features
    The Enthusiast Series Modular family is designed to balance affordability with important features like high-efficiency, continuous rated power output, tight voltage regulation, and low ripple and noise, to deliver a power supply that meets the needs of your performance PC.
  • Modular design
    With its semi-modular design, the TX750M lets you build your system with only the cables you need, reducing clutter, and improving airflow. There's no tangle of extra wires to deal with, so your system looks neater and is easier to upgrade.
  • High-efficiency
    Thanks to advanced power circuitry, including DC-to-DC power conversion, the TX750M is 80Plus® Bronze certified and ErP-compliant, and is guaranteed to operate at 82% or higher efficiency, even at maximum load.
  • The Corsair advantage
    With more than 15 years of building enthusiast-grade memory and components, we've earned a reputation for quality, compatibility, and performance. Need help? We're available by phone call, email or web forum.

Also found here are a few pictures of connectors, a connector count list, some specs, a fan curve graph, and an efficiency curve graph.

Elsewhere on the box, we find some more items of interest:


  • Auto-switching circuitry provides universal AC input from 90V-264V
  • Supports ATX12V 2.3 and EPS12V 2.91 standards and is backward compatible with ATX12V 2.2 and 2.01 systems
  • Dimensions: 150mm x 86mm x 160mm

Ah, look - more marketing.

Built for gamers, overclockers, and high-end system builders.

Engineered to deliver clean, continuous power under adverse conditions.

The semi-modular cable design gives you the flexibility to connect only the peripherals you need.

Backed by a five-year warranty and legendary Corsair customer and technical support.

Enough of boxes and cardboard. Let's open this up.

Aha - a box within a box housing a power supply. I bet I find one right under that foam right there.

Sure enough, there's a power supply in there, encased in a velvet bag. Also present are some modular cables, a power cord, a warranty guide, a safety booklet, and a bag of other accessories.

The warranty guide and safety booklet, the latter of which instructs you to go download the manual if you need one.

Here's what I found in the accessories bag. Numerous zip ties, a case badge, and some screws.


Here's the unit itself. Gotta love that matte black color, and that "lets get you set up with a nice juicy steak" fan grille.

From another angle, we see the modular connectors and... wait, that's it? Just four?

Another look at the fan grille. I suddenly have a craving for a burger. A Texas sized burger, if you will.

A side view, for your viewing pleasure.

Here's the label. Total 12V power adds up to 744 watts, which is pretty close to the full output of the unit. No surprise here - this unit does use voltage regulator modules for the minor rails powered directly from the 12V.

I... have to be honest here. The bag of modular cables doesn't come with a lot of them. Now, we haven't seen the hardwired cables yet, but it almost seems like we're just paying lip service to modularity here.

A better look at the modular connectors on the unit. It almost seems like there's room for many more connectors, what with that third screw hinting that the PCB is much longer than is being used. We'll have to see what the story is on page four.

Uh, yeah. That's a lot of hardwired cabling, right there. Reminds me of the old Antec Signature 850W. It is indeed modular, but barely. Some rigs, particularly those with no need for traditional Molex connectors, could still run into issues with hiding excess cabling.
