Hello everyone. Once again, it is time to have us a look at yet another new power supply offering. Not too long ago, I had me a look at a new unit from XFX in the XPS 650W XXX Edition. While that unit wasn't shy about raising expectations due to the sheer number of X's in the product name, I did find a few minor issues in that unit's handling of low load levels that gave me some pause.

This time, we'll be checking out the Black Edition 750 watt model. All things being said, this unit bears more of a resemblance to the most excellent 850 watt unit I reviewed as XFX's first Black Edition model. As such, I have some high expectations this time out, for Seasonic's M12D platform is the basis for both models.

All the marketing starts on the back of the box, unless you count the little 80 Plus Silver logo that was on the front of the box. I'll just reprint some of the goodies here:

The XFX Black Edition 750 watt modular power supply gives you the power you need with a brilliant combination of form and function. Giving more than just life to your PC, this power supply allows easy cable management with modular connectors which helps increase airflow. With tight voltage regulation and high efficiency operation up to 88% (80 Plus Silver) this power supply will give you exactly what you need to keep your gaming charged and ready.

And there are a few "key features" bullet points to mention as well:

  • 750W of continuous power at 50°C
  • Detachable Modular Cables
  • High quality Japanese brand capacitors (105°C)
  • Tight voltage regulation (±3%)
  • High efficiency operation up to 88% (80 Plus Silver)
  • Single, high power +12V rail (up to 62A/744W)
  • DC to DC Voltage Regulator modules for +3.3V and +5V
  • Solid polymer caps provide enhanced reliability and stability
  • Quiet 135mm ball bearing fan provides superior cooling
  • Supports multiple high-end graphic adapters (SLI & Crossfire)

Finally, there is a list of all the connectors present on the cabling of the unit, as well as an assertion that all cables are sleeved in black mesh for optimum cable management and airflow. Oh, and apparently we're supposed to play hard.

Over on this side of the box, we get a simple load table on what the unit is capable of. Nothing we're not used to here at this site. But since I've been told to play hard, I think I'll headbang to AC/DC as I turn the box around again.

Headbanging makes me dizzy, so I'll stop for now. Yep, says the box, this is a 750 watt model. Time to remove the outside sleeve and get to unpacking the unit proper.

Hmm... the packaging must be aware that I didn't really try to play hard. I'll have to try harder. What you're looking at here is a small box clipped onto the top of a larger box. It's hard to explain, but perhaps the following picture will do it. Let's breakdance over to the next picture now.

Ouch! Folks, if you're as tall as I am, it's a really good thing to make sure there's adequate room for breakdancing before you go ahead and try it. Whacking your ankles on metal table legs isn't fun. I'm done playing hard for now.

Instead, I'll call your attention to the above picture. As you can see, the smaller box clipped to the larger box is for the modular cables and their containing bag. The bigger part is for the power supply itself as well as a user guide and power cord.

Here's everything unpacked for you. A bag of modular cables, a power cord, a power supply, and the user guide.

Speaking of that user guide, you've just seen all of it. A few rudimentary pieces of information and that's it. I guess saving paper is a good thing.

Here's the power supply itself. As you can see, the unit comes with gray mounting screws already present in the mounting holes. My advice is to make sure you don't lose them - like the last XFX unit I looked at, these are threaded like optical drive screws. The regular machine screws used for mounting most power supplies will not work for this puppy, a design decision I still find a mite baffling.

I'm still a bit put off by that radioactive green fan, but am warming up to it somewhat. You know what would be cool? If this power supply turned into the Incredible Hulk. That would be sweeeeeet.

Dude, this is, like, the exhaust end of the unit and junk. Hold on... I left MTV on, and it's going to my head. Hey, remember when the "M" stood for "music?"

Ah, that's a better channel. Mythbusters is on, so I should be in the right mood to try and blow something up pretty soon now. I'll be doing that on page two and three when this unit goes through my load testing procedure.

Play hard! Play hard I say!

Here's the familiar green XFX cooling fan in all its glory. I fully expect that if you put three dozen of these fans together in a square, you can probably signal the International Space Station by bouncing flashlight beams off of them.

Here is the actual load table printed on the unit. As is common for units using DC-DC conversion, you can just about draw the unit's total capacity right off the 12V rail by itself.


+3.3V +5V +12V -12V +5VSB
24A 30A 62A 0.8A 3A
Max Power 150W 744W 9.6W 15W

The hardwired cables on this unit include two EPS/ATX12V cables (one a modular 4+4 pin), two modular 6+2 pin PCI-E connectors, and the usual ATX mainboard connector.

The modular cable connectors up close. The two 8 pin connectors are for the two additional PCI-E cables, while the 6 pin jobs are for the Molex and SATA chains.

I was pleased to see that none of the modular cables proper had those little annoying 3.5" drive connectors, and that those connectors were provided for through the use of a separate adapter. Less clutter is a good thing, and not too many devices use those little connectors anymore.

Type of connector: XFX XPS-750W-BES
ATX connector (500mm) 20+4 pin
4+4 pin EPS12V/ATX12V connector (530mm) 1
8 pin EPS12V (530mm) 1
6+2 pin PCIe (570mm) 2
Modular Cables
SATA (350mm+150mm+150mm) 3
SATA (450mm+150mm+150mm) 3
SATA (550mm+150mm+150mm) 3
5.25" Drive (350mm+150mm) 2
5.25" Drive (450mm+150mm+150mm) 3
5.25" Drive (550mm+150mm+150mm) 3
Single 5.25" to dual 3.5" Drive adapter (150mm) 1
6+2 pin PCIe (550mm) 2
Unit Dimensions(L x W x H)
170mm x 150mm x 86mm

Another thing I was pleased to see was the continuation of a trend from the 850 watt model, and that is peripheral cables of differing lengths. This should make cable management a fair bit easier for some folks.
