Corsair TX750W Power Supply
Corsair has enjoyed a reputation for over-building their computer power supplies while offering them at a price that affords the enthusiast a good value. Is their new flagship 750w unit of the same quality? An 850w PSU in sheep's clothing?
Overview
The first thing we are going to look at with the Corsair TX750W is its packaging, accessories, and documentation. While normally none of these items is a make or break item for a power supply the packaging quite often contains a lot of information about the product we are purchasing. The inclusion of an owner’s manual that provides actual information about our product is also of great help in many situations. Accessories are almost unnecessary with a power supply as the unit is self contained, unless it is modular, but there cases where a manufacturer can include useful accessories to make installation, routing and use more efficient.
The packaging of the Corsair TX750W fits in the trend of all of the other Corsair units to date but with a new accent color, orange. The packaging has a fair amount of information about the unit enclosed including the connector count, power label (which will be broken down below), fan noise level graph, and an efficiency graph. The efficiency graph and text indicates the unit peaks at 85% efficiency (or a bit above), but that value appears to be derived at 230v AC input with the 120v peak at about 84%. The units packaging also indicates the inclusion of “High-quality Japanese capacitors” like previous Corsair offerings and “powerful +5vsb with 3A rating” along with APFC coupled with the various typical safety features. Also included on the box is a listing of all the connectors that the unit has complete with pictures. Like the last Corsair unit we saw the box proudly promotes the fact that the unit has a full 5 year warranty. This is the second longest warranty we have seen to date in our reviews trailing only the Limited Lifetime Warranty offered by Ultra and BFG (PC Power and Cooling has recently, post our reviews, extended their warranty support on both the Turbo-Cool and the Silencer lines technically making the Corsair’s 5 year warranty the 4th longest now). The warranty information can be found on the Corsair website and in the manual (both included and online) and as such is reprinted below.
The Product is guaranteed for sixty (60) months from the date of delivery to the end-user against defects in materials or workmanship. During this period, the Product will be repaired or have parts replaced, at our discretion, provided that: (I) the Product is returned to the agent from whom it was purchased with shipping prepaid; (II) the Product has been purchased by the end-user and not used for hire purposes; (III) the Product has not been misused, handled carelessly, or other than in accordance with any instructions provided with respect to its use; (IV) the Product has not been damaged due to acts of nature, such as lighting, fire, flood, or earthquake; (V) the warranty stickers have not been removed or tampered with. Corsair Memory’s warranty on the Product is to the first end user or consumer only, in accordance with the Corsair Memory’s Limited Warranty.
As one would expect from a 750w power supply the unit is billed as being multi-GPU capable but at the time of writing the unit does not appear on either the SLIZone or ATI CrossFire website. However, from the specifications below the unit seems capable of powering most any dual high end graphics card with ease in most users systems and given the certification of Corsairs previous high-end offering, the HX620W, it seems only a matter of time before the TX750W is certified for SLI or CrossFire as well.

The Corsair TX750W is a single 12v rail power supply from CWT and it shares this 12v arrangement with all of Corsairs previous Seasonic based power supplies that we have reviewed. That single 12v rail is rated at 60A which makes it good for a possible 96% of the unit’s total DC output capacity depending on system load. This is impressive and is reminiscent of Corsair's previous top of the line Seasonic based HX620W. To go with this impressive 12v capacity the unit has been paired with 4 modified 8 pin PCI-Express connectors. The 8 pin connectors are 6 pin connectors with two additional taps off of grounds to feed the two remaining pins. The TX750W also has 8 Molex connectors for peripherals and 8 SATA connectors good for powering your RAID array. Overall this flexible, well appointed setup should make this unit a natural fit almost any high end PC.
Once we open the packaging we see the usual assortment of items including the power supply in a pouch like the VX450W, cables, mounting screws, user manual, zip ties, and a case badge. The user manual now comes in 8 languages spanning about 5 pages per language and is meant to cover both the TX750W and the TX650W. The manual includes the power table, installation instructions, cable lengths, and warranty information. This is most of the desirable information in a manual, especially the warranty information, but it isn't as complete as some other manuals we have seen that include all the electrical specifications and the pinouts.
