A Closer Look
I was pleasantly surprised by the high quality look and feel of the Corsair packaging. There is lots of information provided on the back.
Upon opening the package, I was greeted with ample protective material and a very nice branded sack to keep dust and other packaging particles out of the PSU.
It was nice of Corsair to throw in a case badge, black mounting screws and even some zip-ties for cable management. As an added bonus, the power cable included is a thicker 16AWG cable—another nice touch. There are specifications and basic installation instructions included in the manual.
Corsair stuck with the muscle car colour scheme with the TX750. Although it is not as subtle and understated as the PC Power and Cooling PSUs, I think it is very attractive looking without being overly flashy. A trend you will also see with Corsair’s memory modules. The Corsair TX750 employs a very durable powder coat finish that is scratch resistant. You really need to see one of these PSUs in front of you to appreciate its quality look and feel.
I love the logo at the rear of the PSU. If you don’t have a windowed case, you can still show off the most important component in your system—a nice aesthetic touch.
Above you can see the VX550 sitting next to the TX750. The large 140mm fan covers just about the entire bottom of the PSU.
As you can see above, there are quite a few cables to hide away in your case. The modular interface of the HX series looked a bit more enticing after feasting my eyes on this nest. It is definitely “Function over form” with the TX series. I was pleased to see that the cables were not only sleeved to the first connector, but every section was covered giving it a higher quality look. The leads are also much longer that what I am used to seeing. Even in large full tower cases or cases with a lower PSU mount, you won’t have issues.
There are no fewer than four PCI-Express connectors on the TX-750. Not only are there four but all four are 6+2 style connectors. None of the PCI-E cables are shared either—they are all separate leads running back to the main PCB. If you are wondering, the two piece connectors can be snapped together if you do need an 8-pin PCI-E connector.
Just like the VX550, the TX750 is not sleeved right into the PSU casing. This is not that big of a deal, but it does put a bit more stress on the cables near the grommet and it simply looks a bit messier. This was the first hint of CWT build in the TX750 that I observed.
Upon cracking open the TX750 and kissing the warranty goodbye, it was immediately evident that it is indeed a CWT built power supply. It is very similar in construction to the CWT built Corsair VX550. The thick black heatsink fins and green tape wrapped components are a telltale sign. Interestingly, the TX750 board could have easily fit in a standard size PSU casing had it not been for the oversize 140mm fan. It is only three quarters of an inch longer, which is not that big of a deal for the majority of buyers out there. The TX750 is clearly targeted towards those with high power, multi-graphics card systems that are most likely using mid or full tower cases so this is pretty much a non-issue in my opinion.
The fan used in the TX750 is a Yate Loon D14BH-12 model. Although it may not look like much, it’s a monster. At 12V, it is rated for 2800RPM, 140CFM and 48.5dB. Thankfully, these fans are temperature controlled by circuitry in the PSU so it should be very quiet during normal operation. It is nice to know that a great deal of potential cooling power is on tap if the PSU gets too hot. A clear plastic deflector blocks about half of the fan—I assume this is done to force all airflow to the front of the PSU where positive pressure will force it through the heatsinks and components on its way out the rear. Without it, a fair bit of air towards the rear would probably escape directly out the back without being put to good use. I’d expect the deflection of airflow in this manner to increase noise and put some added stress on the fan motor. This is an interesting design consideration that I’m not totally sure is positive. The VX550 has this same plastic deflector. Surely, it is easier and less expensive to just build the PSU without this deflector so it must be there for a reason. I’m sure the experts at Corsair and CWT have deemed it a necessary or beneficial addition.
The Primary capacitor used in the TX750 is a 390uF Matsushita (PET) model rated for 105’C. On the secondary side, Nippon Chemi-Con capacitors are used. As advertised, Corsair/CWT used top-quality Japanese capacitors in this PSU. The VX550 employs a slightly smaller 330uF Nippon Chemi-Con primary. The other components and heatsinks used appear to be sized appropriately for the rated output of this PSU. The TX750 and its little brother, the VX550 are built well with clean soldering and an effective internal layout. Overall, I was very pleased with what I saw.
