The semi-modular Corsair TX750M claims to be the perfect PSU for high heat case environments as it is rated for continuous output at 50C. We will test it in the hotbox up to 45C, as that is torture enough. Does it deliver Gold rated efficiency and great power inside the incubator?


Corsair is known in enthusiast circles as a supplier of high performance memory and has risen to become one of the most talked about power supply brands around. Corsair was initially able to establish a presence in such a short time through the use of quality OEM’s (Seasonic and CWT), rigorous standards, and excellent support. Since its entrance into the PSU field, it has established a number of lines of power supplies of varying quality to address (and overlap) just about every market segment. Today, Corsair brings us a new revision to and old classic from their TX-M line; the TX750M (CP-9020131). This unit is produced in conjunction with Great Wall.

China Great Wall Computer Group Co. Ltd., a subsidiary of China Electronics Corporation, is a name that is not that well known to our North American readers. Great Wall was founded in 1986 and currently operates a number of companies producing products including power supplies, monitors, laptops, memory, flash products, and a laundry list of other PC and technology related products. In the power supply field, Great Wall is currently one of the largest suppliers of power supplies in the Chinese market. Its presence in North America, however, is limited as we have only seen Great Wall products far from OCZ, Riotoro, and Corsair.

TX750M - Deja Vu?

Today's Corsair TX750M is another product refresh from Corsair similar to what we saw from the recent HX1000. In this case, though, we are looking at a slightly different and smaller capacity product as the TX-M line slots in below the HX line in Corsairs product offerings. With that being the case, today's TX750M is going to find itself in a much more crowded product segment where not only is performance important but so is price. This is not always an easy balancing act and, in fact, the last two 750W units we have seen from Corsair that were in market segments that would not quite be called "flagship" or "high end" ran into a few issues. So, how this unit will perform in general, and relative to the competition, is certainly up for grabs today. Before moving on, let’s see what Corsair expects from this ship:

TX Series semi-modular power supplies are ideal for basic desktop systems where low energy use, low noise, and simple installation are essential. All of the capacitors are 105C rated, Japanese brand, to ensure solid power delivery and long term reliability. 80 PLUS Gold efficiency reduces operating cost and excess heat. Flat, sleeved black modular cables with clearly-marked connectors make installation fast and straightforward, with good-looking results.

Moving on let’s see what we can expect when a user purchases the Corsair TX750M power supply in retail in terms of documentation, accessories, cable count, rail layout, output characteristics, and general build quality.
