    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. Reply

    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 Reply

    i dont get why it wont do crossfire... Reply
  • JarredWalton - Sunday, November 02, 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. Reply

    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. Reply

    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.

    A mfg. can use different designs or components to produce a top-of-the-line PSU or lower quality components or simpler designs to make a run-of-the-mill PSU. Personally I have used the PCPC brand of PSUs for many years and I have found them to be reliable, stable, high-quality PSUs that have always delivered top performance.

    I personally would not buy another brand to save a few dollars when the PSU is the very heart of any PC and as such essentially determines the performance and stability of the entire PC. I realize many people will spends hundred on the latest, greatest, trick-of-the-week Video card or memory and then buy an inferior PSU to save $20.

    It's foolish economics in my experience. My overclocks always seem to be equal to or better than most folks and I never experience the mysterious crashes that I read about from people using the same hardware other than a quality PSU like the PCPC units.

    Starting reading this hoping to find out I picked the right PSU last Christmas... but it seems I missed. Overall I've been happy with it, but perhaps I would have been even more happy with another. Do you think the ripples and noise in this PSU would greatly effect overclocking results?

    My only big complaint about this PSU is that I'm not very sure of whether or not I could get a case with the PSU mount on the bottom. The motherboard and CPU power cables seem to be on the short side. Christoph, have you had any experience with this?

    Good article, thanks!

    I have a TX750W installed in my Antec 300 (bottom mount). It's powering an Asus X38 motherboard with 4GB DDR3 and three video cards (so far): 2x8800GS and a G92 8800GTS. Runs F@H nicely. Very low noise, I cannot hear it over the two stock 300 fans, AF7P and three GPU fans (AF7P is probably the loudest thing in there). The bottom mount setup is quite nice for this rig as it pulls hot air from that "dead spot" under the lowest video card and keeps that one running fairly cool. Reply

    Hi, I think it would do fine with this PSU as it has longer cables as usual. With the 60cm/24" you will not have too many probs with bottom mounted cases. As for the ripple I think the results is rather normal. The limits are much higher. Reply

    Thanks for the reply, that helps a lot!

    ... now to find the money for that case

    Interesting article that came a bit late for me. I debated whether or not to get the Corsair TX650 or the TX750, but went with the TX750 because with a rebate it was cheaper than the TX650. Should have got the TX650. Oh well, my system will in no way tax the PSU as my system will not even pull 300W at full tilt. So the TX750 should last me a long while.

    As for it being loud, I have four Yate Loon 120 case fans (running about 1300rpm) and a case with a mesh front (that sits on the floor), so all I can say is that it is not noticeable with my setup.

    I would like to also thank you for such an in depth PS article. I really hope with this new test setup that you'll take a step back and build a matrix of PS statistics. I think you wouldn't even need to give a big writeup on each one just post one article that is your test setup and then start posting numbers for different existing PSUs.

    Very Nice.

    I've ready several articles about the TX750W's little siblings performing extremely well. Are there any plans on testing either of these two PSU's?

    Here's a link to a review of the VX450W at They claimed it to be one of the best if not the best 500W range PSU available, which is about optimal for most gaming pc's out there.

    The TX line is built both by Seasonic and CWT too: the TX650 is built by Seasonic, while the TX750 is made by CWT. Reply
  • JarredWalton - Thursday, October 30, 2008 - link

    That's what we stated with the following, although we didn't explicitly list any models:

    "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."
  • Christoph Katzer - Thursday, October 30, 2008 - link

    There was a sentence suggesting the TX650 could be also CWT, but I changed it after. Reply

    Thanks for the article, one suggestion for future consideration, it would be interesting to see some of the graphs comparing like for like with with other PSUs.
