Corsair TX550M Power Supply Review

The TX550M shares the exact same chassis with the more powerful TX750M unit. It is an all black power supply, sprayed with a matte black pain and Corsair enhanced it aesthetically via a better fan grill and embossments on all sides.

Corsair’s usual decorative stickers with the unit’s model and company logo can be still found at both sides of the power supply. The embossed chassis also forms a frame around the stickers, creating a much higher quality visual effect.

The sticker with the unit's electrical specifications can be found at the top of the chassis and there is no frame surrounding it, which is understandable as it will not be visible at all inside most cases.

The rear is entirely perforated to allow for the air pushed by the cooling fan to escape towards the outside of the case. The unit uses a standard AC power cable and there is a standard rocker on/off switch at the rear, as well as a tiny sticker with the unit’s model logo.

There is nothing of interest at the front side of the chassis, save for the few connectors of the modular cables. This is a partially modular unit design with most cables still hardwired to the power supply. This unit offers the following number of connectors:


Native cables

24-pin ATX connector

1 x 4+4 pin EPS12V/ATX12V CPU connector

3 x Molex connectors

3 x SATA connectors

2 x Floppy connector*

Modular cables

3 x Molex connectors

3 x SATA connectors

2 x 6+2 pin 12V PCIe connectors


*Editor’s note: the floppy connectors utilize Molex connectors through adapters.
