Corsair recently refreshed their TX Series power supplies which now include four new models: the TX550M, TX650M, TX750M, and TX850M. The new TX-M Series sits right in the middle of Corsair’s PC power supply lineup and was designed to offer efficient operation and easy installation. Corsair states the TX-M Series power supplies provide industrial build quality, 80 Plus Gold efficiency, extremely tight voltages and come with a semi-modular cable set. In addition, the TX-M Series power supplies use a compact chassis measuring only 140mm deep and come backed by a 7-year warranty.
We will be taking a detailed look at the TX-M Series 750W power supply in this review.
The TX750M is 80 PLUS Gold-certified, and it also carries ETA-A and LAMBDA-A- certifications for efficiency and output noise, respectively. Under a continuous full-load output, the PSU's maximum operating temperature is 50°C, and it includes all of the protection features we'd expect.
Cooling is handled by a 120mm fan with rifle bearings. We would prefer if Corsair used a larger fan, but the PSU's physical dimensions must have prohibited this. There is no semi-passive mode, which some enthusiasts might miss. However, if the fan profile is tuned correctly, that shouldn't be a problem.
The +12V rail can deliver up to 62A, while the minor rails muster a 130W maximum combined power output. The 5VSB rail is also ample, providing a 3A maximum current output. Many similar-capacity PSUs are limited to 2.5A on this rail.
Corsair TX-M Series PSU Key Features:
• 550W, 650W, 750W, and 850W models
• Server-grade 50°C max operating temperature
• 7-Year warranty
• 80 PLUS Gold certified
• All capacitors are Japanese brand, 105°C rated
• Compact chassis measures only 140mm (5.5”) deep
• Quiet 120mm cooling fan
• Semi-modular cable set
• Comply with ATX12V v2.4 and EPS 2.92 standards
• 6th Generation Intel Core processor Ready
• Full suite of protection circuits: OVP, UVP, SCP, OPP and OTP
• Active PFC with full range AC input (100-240 VAC)
Technically, the TX 750M is a solid design. Ripple suppression rates as excellent, with all rails falling well within industry rated tolerance specifications and it passed the cross load test with flying colors. The build quality is generally very high inside and its always reassuring to see that 105c Japanese Capacitors are used throughout – especially for long term stability and reliability.
Thankfully, only the necessary cables are soldered on. Everything else is modular. The sole shortcoming we spot is the TX750M's single EPS connector, which restricts its compatibility with some high-end motherboards. Then again, the RM750x only has one EPS connector, so we shouldn't expect the TX750M to come with two.
Cable length is good, though the distance between connectors should be greater, especially in the four-pin Molex connectors.
It's also a little strange that Corsair includes two FDD adapters. Even in very high-capacity power supplies, we usually only get one since it's hardly used anyway.
The fan isn't centered on the top cover, which looks a little weird. But that's probably the best place for it; if it was in the middle, airflow across the APFC converter and primary FETs wouldn't be optimal.
Up front, we find a typical honeycomb-style exhaust grille and the power switch installed below the AC socket, with the fan facing upwards.
The modular panel only sports six sockets: two for the PCIe cables and four for the peripheral ones. There is a grommet around the cable exit hole, and the native cables are fully sleeved back into the PSU's chassis.
