Corsair TX750M Power Supply Review

Hardware Secrets Bronze Award

Introduction

Corsair is releasing the third version of their popular TX power supply series, dubbed “M,” for “Modular.” However, it is really important to understand that this new version isn’t simply a TX or TX V2 power supply with a modular cabling system added; the internal design is completely different. The TX M series has 550 W, 650 W, 750 W, and 850 W models, all with 80 Plus Bronze certification. (The TX V2 series doesn’t have a 550 W version, and Corsair still offers a 950 W model under the first TX series.) Let’s take a look at the 750 W version of the TX M series.

The manufacturer behind the TX M series is CWT, the same manufacturer that was in charge of the first version of the TX series. The TX V2 series, however, is manufactured by a different company (Seasonic). Therefore, the TX M series power supplies can’t be TX V2 units with a modular cabling system added. We’ve already reviewed the first version of the TX750 and the TX750 V2, in case you want to compare the new TX750M to the previous two models.

The Corsair TX750M is 6.3” (160 mm) deep, using a 140 mm ball bearing fan on its bottom (Yate Loon D14BH-12).

As explained, this unit has a modular cabling system, with six cables permanently attached to the power supply, using nylon sleeves. The modular cabling system has four connectors, two black for SATA/peripheral power connectors and two blue for video card or EPS12V power connectors. This power supply comes with the following cables:

  • Main motherboard cable with a 20/24-pin connector, 22” (56 cm) long, permanently attached to the power supply
  • One cable with one EPS12V connector, 23.2” (59 cm) long, modular cabling system
  • One cable with two ATX12V connectors that together form an EPS12V connector, 24” (61 cm) long, permanently attached to the power supply
  • Two cables, each with one six/eight-pin connector for video cards, 24” (61 cm) long, permanently attached to the power supply
  • Two cables, each with one six/eight-pin connector for video cards, 23.6” (60 cm) long, modular cabling system
  • One cable with four SATA power connectors, 15” (38 cm) to the first connector, 5.9” (15 cm) between connectors, permanently attached to the power supply
  • One cable with four SATA power connectors, 15.7” (40 cm) to the first connector, 5.9” (15 cm) between connectors, modular cabling system
  • One cable with four standard peripheral power connectors, 15.7” (40 cm) to the first connector, 5.9” (15 cm) between connectors, modular cabling system
  • Two adapters to convert standard peripheral power connectors into floppy disk drive power connectors

All wires are 18 AWG, which is the minimum recommended gauge.

The cable configuration is good for a 750 W product, with eight SATA power connectors and four video card power connectors.
