A Detailed Look
The Corsair TX750M power supply enclosure is painted with a matte black finish and measure only 140mm (5.5”) deep. The back panel includes an AC receptacle, main power On-Off switch and open honey-comb grill.
The power supply uses a Corsair labelled 120mm, seven blade fan on the bottom for cooling. The fan (NR120L) is rated for 0.22A at 12 VDC and uses a riffled sleeve bearing for quiet operation.
The front panel on the TX750M incorporates six modular cable connectors that are nicely labelled and keyed so you don’t inadvertently plug a cable into the wrong connector.
The PSU comes with two fixed cables and the rest are flat ribbon-style modular cables which all appear to be industry standard 16 AWG wire. I actually prefer the semi-modular cable set over fully modular (it’s not like the 24-pin ATX and 4+4 pin EPS cable/connectors are optional).
Under the Hood
Here are a few pictures showing the layout and components inside the new Corsair TX750M power supply. Corsair is using Great Wall this time around as the OEM for the TX-M Series.
The TX750M features a modern LLC resonant circuit design with DC-to-DC converters for increased efficiency. The layout of components is clean while the soldering appears to be good. All of the capacitors used inside the PSU are high-quality Japanese made electrolytic and solid polymer caps. For example, the TX750M uses two Nippon Chemi-Con bulk capacitors rated for 330uF, 420V and 105°C.
The Tomshardware review
The Tomshardware review mentioned that the fan gets really noisy at ambient temperatures over 35 degree celsius, leading the fan to spin at 1300 RPM even at 20W load. Have you experienced anything like this?
