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.

    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.

    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.

    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.
