The Corsair TX series has admittedly been in the market for a while, but we wanted to add another Corsair power supply to our pile of results. Corsair tends to be somewhat conservative with their power supplies, which isn't necessarily a bad thing. Their highest output power supply is "only" 1000W, the previously tested HX1000W, and today we are reviewing the TX750W. All of their other power supplies are rated at 400W to 650W. It's nice to see that Corsair doesn't feel the need to follow the current market trend of pushing extremely high wattage power supplies on users.

Corsair power supplies come from two different ODMs, Seasonic and Channel Well (CWT). Both are very good manufacturers for high-end products, but Seasonic tends to be a more conservative company that doesn't want to grow their business too fast whereas CWT is kind of the opposite and is interested in selling a large number of power supplies through many different companies. Corsair blurs the boundaries between these ODMs, letting the two manufacturers produce different wattages for the same series.

The TX series is a high performance series that doesn't include extra features like cable management. If you prefer cable management, you should look at Corsair HX series -- which we will be reviewing shortly. We also reviewed theVX450W, which did well in our low wattage roundup a year ago. However, the VX450W was produced by Seasonic while Channel Well makes the TX750 power supply.

The label shows a single 12V rail with a massive 60A, which is common for Corsair products. The smaller voltage rails feature 30A and 28A and a combined power of up to 180W. Today's systems do not need much power from the smaller voltage rails, so the 180W combined power is acceptable.

    Holy Voltage Ripple Batman!

    I can't believe that a Corsair PSU is that bad at load. If I were running the test, I would double check to make sure I wasn't loading it improperly, because I wouldn't expect such a poor showing. I kind of hope that it was an error on your part, since I don't know any other manufacturers that make silent PSU's with the quality Corsair usually provides. PCP&C are always rock solid, but they usually are a little loud.

    Well, I'm very happy with my Corsair units, and so are the people which I recommended them to. It's good quality without being extremely pricey. I trust mine as much as any other high quality brand. Haven't gotten a TX750 yet tho, I've mostly gone with the Seasonic sourced ones.

    I have two Corsairs's where OEM is Seasonic; they are great and the reviews reflect that. The non-Seasonic Corsairs are not the same quality, as this review reflects

    i dont get why it wont do crossfire...
  • JarredWalton - Sunday, November 2, 2008 - link

    It will do CrossFire just fine - it's just not CF certified by AMD/ATI. But then, is that even something that they do? I don't know.

    Actually the TX750 is certified as well:">

    "We also received an HX520W recently"

    recently? This psu was one of corsairs first and its like 2 years old now, how come u're just receiving it now??

    I don't know why it's not clear that there are a few PSUs more than just Corsairs. We do our best but can't have all the time the latest stuff from each company. And like in this case if we forget a unit we test it later again after it settled.

    Excellent review, especially considering the price changes on the market. I recently upgraded my PSU and this one was one of the considerations. I went with the PCP&C 610 Silencer, slightly less expensive and I like the Continuous @ 40c guarantee that they offer.

    By the way, the most recent BFG models in the price range also offer the same "40c" performance guarantee and get excellent reviews.

    I don't know why Corsair stopped using that as part of promoting their products.
  • Barbarossa - Thursday, October 30, 2008 - link

    Actually, all the TX750 is Continuous @ 50C.

    The only PSU we sell that's rated @ 40C is the CX400.
