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?


Corsair has been known among enthusiast circles as a premier supplier of high performance memory for quite some time and has recently risen to become one of the most talked about power supply brands around. Corsair was able to establish such an amazing presence in such a short time through the use of quality OEMآ’s (Seasonic and CWT), rigorous standards, and excellent support. Corsair began branding power supplies with two units, the very well received CMPSU-HX520 (branded as HX520W) and the CMPSU-HX620 (branded as HX620W). Recently they have established a new line of power supplies and released two more units, the CMPSU-VX450 (branded as VX450W) and the CMPSU-VX550 (branded as VX550W). Not content to stand still Corsair has gone ahead and introduced a third line of power supplies, the TX series, which we will be covering today. The TX series currently consists of the CMPSU-TX750 (branded as TX750W) and the CMPSU-TX650 (branded as TX650W). Today we will be looking at the TX750W that Corsair is selling in conjunction with builder CWT.

Channel Well Technology (CWT) was founded and began manufacturing power supplies in 1993. Since 1993 Channel Well Technology products have shown up under various guises including Antec, Xclio, 2theMax, CWT, ThermalTake, and now Corsair. While most familiar to our US users from when they used to provide OEM services for Antec, CWT is one of the more complete OEM manufacturers as they have a fairly high level of vertical integration providing transformers all the way up to their well designed independently regulated SMPS. Recently however, CWT has begun stretching out and is providing OEM services for a number of brands as todayآ’s unit demonstrates.

Lettre de Marque...

For some time now users have been clamoring for higher powered offerings from Corsair due in large part to the phenomenal acceptance of their HX series. Today, Corsair makes good on those wishes by granting their Lettre de Marque to the TX750W as it sets sail for the highly competitive grounds currently inhabited by companies like Antec, Silverstone, PC Power and Cooling, Enermax, CoolerMaster, and more. In the process they have committed themselves to some lofty goals:

Enthusiasts looking for the optimal in price performance PSU technology will find the Corsair TX series of PSUs will meet even the most demanding of required specifications. The Corsair TX power supplies are engineered using advanced technology and components typically found with high performance power supplies. With design features such as a dedicated, single +12V rail offer the maximum compatibility with the latest system components. Energy efficient circuitry capable of delivering greater than 80% efficiency ratings across 20%, 50%, and 100% load conditions make the TX family of PSUs ideal for the value/quality conscious enthusiast. With a large 140mm (120mm on TX650W) diameter temperature-controlled fan that is ultra quiet, yet still more than sufficient to cool the internals of the system, reliability and stability are no longer worries for the gamer, overclocker or enthusiast and high-end system builder.

Will the Corsair TX750W go the way of Rأ©nأ© Duguay-Trouin or will it simply slip silently beneath the waves, the victim of a broadside?

Now that we know what Corsair expects from this power supply letآ’s see what we have to look forward to when we purchase the value oriented TX750W in terms of documentation, accessories, cable count, rail layout, output characteristics, and general build quality.
