Corsair TX750 Power Supply Review

Corsair TX750 Power Supply Review

Corsair has always been a name synonymous with quality. Since their inception in 1994, Corsair has been one of the most highly regarded PC memory module designers and manufacturers. Today, Corsair has more than just memory in their product lineup. They offer PC cooling products, flash memory and even power supplies.

Corsair made a huge splash in the PSU industry when they released the very successful HX620 and HX520 series power supplies in 2006. Receiving dozens of awards, Corsair proved that they could translate their reputation for quality memory, into the power supply market. Not long after offering the modular, multi-rail HX620 and HX520 PSUs, Corsair released the non-modular VX series, which was targeted to the more price conscious buyer. The VX450 and VX550 were instant hits and as highly regarded as the HX series. Following the success of the VX series, Corsair recognized that buyers were looking for cost-effective, higher power solutions that employed single +12V rails. Enter the TX series.

Today we are going to take a look at Corsair’s flagship model, the TX750.

Specifications and Features

There are two PSUs in the TX series from Corsair, the TX650 and the TX750. The TX series is very similar to the VX series as far as features are concerned—just built to higher output specifications. Before Corsair sent us this TX750 sample, I had actually bought a VX550 based on some of the great reviews I had read. I’ll be making some comparative references between the two models throughout the review.

Corsair TX Series Features (taken from the Corsair TX650/TX750 product website)

  • Supports ATX12V v2.2 standard and older ATX12V 2.01 spec
  • Ultra-quiet 120mm (140mm on TX750W) double ball-bearing fan delivers excellent airflow
  • 80%+ energy efficiency at 20%, 50% and 100% load condition for less heat generation and lower energy bill
  • 99% Active Power Factor Correction provides clean and reliable power to your system
  • Universal AC input 90~264V automatically scans and detects the correct voltage
  • Dedicated single +12V rail offers maximum compatibility with latest components
  • Over Current/Voltage/Power Protection, Under Voltage Protection, and Short Circuit Protection provide maximum safety to your critical system components.
  • High quality Japanese capacitors provide uncompromised performance and reliability.
  • Extra long cables support full tower size chassis.
  • TX750W Dimension: 5.9″(W) x 3.4″(H) X 6.3″(L)
  • TX650W Dimension: 5.9″(W) x 3.4″(H) X 5.5″(L)
  • MTBF: 100,000 Hours

As you can see, on paper, the TX series PSUs have all of the essential features that we look for in a PSU: High efficiency, 99% active PFC, quiet fan, Large single +12V rail, protection circuitry and high quality capacitors. As I mentioned earlier, you won’t find any modular cabling on the TX series power supplies. It is amazing just how much current these PSUs can supply on the +12V rail—almost the entire power capability of the PSUs are on tap for +12V output. With 60A or 720W on the +12V rail, the TX750 can power just about any modern system today utilizing two top-of-the-line graphics cards. Both the TX650 and TX750 are ‘SLI Certified’ by Nvidia.

One specification of interest is the larger 140mm fan on the TX750 model. You’ll also notice that the TX750 is about three quarters of an inch longer than the TX650. I’ll be cracking the TX750 open shortly to see why the extra real estate is necessary.

    Winfrey Very good article Mike! Hopefully more people are realizing that quality systems these days mean starting with quality power. And this PSU definitely seems to deliver!

    We hope to have a quality oscilloscope in the lab for future PSU reviews.

    get on that prime!

    I also look forward to that article on phantom power draw. Very interesting.

    lemonlime Glad you guys liked the review :)

    I happened to stumble across a yet to be released HX1000 model on Corsair's product page: http://corsair.com/products/hx1000.aspx so even higher power solutions are on their way :eek:

    jared trackbacks ftw lol
  6. Tong Is this psu safe to power three nvidia gts 250 cards? Each of my gts 250 requires two 6-pins power connectors and this psu comes with only 4. I have the molex adapters, but I hear that it isn't safe to use molex adapters. Help.

Howdy, Stranger!
