Packaging and Bundle

The packaging of the TX650W is well designed. The PSU is secured very well inside the package which is held between two thick soft Styrofoam pieces. Noteworthy enough, the PSU is not protected by a bubble bag but a black pouch. After you get the PSU out you can re-use the pouch for any given purpose. Besides the pouch you will also find several black cables ties, black screws and a well written manual inside the package.

The Unit

Much like every PSU Corsair currently offers, the TX650W shares the same aesthetic and cooling design. The chassis is painted matte black, the subtlety of which is broken by the striking yellow stickers found at both sides of the unit. The TX650W is not a modular unit so many cables can be found exiting the front of the chassis. The TX650W (besides the basic 24-pin ATX connector and 8-pin CPU connector) offers two 8-pin PCIe connectors, eight SATA and eight Molex connectors and two floppy connectors. The stronger TX750W version is nearly identical, except that it provides four 8-pin PCIe connectors instead of two.

Corsair is one of the few companies who have decided to put the sticker with the unit’s specifications on the top of the chassis. Most of the rear part of the unit is perforated and only a simple rocker on/off switch can be found. The TX650W is cooled by a single 120mm fan placed at the bottom of the unit. Corsair went with an Adda AD1212HB-A71GL ball bearing fan which can reach a maximum speed of 2200RPM.

The insides of the Corsair TX650W appear very simple. The rather small heatsinks do look rather inadequate for such a rating. The unit is built on a CWT PCB, a popular maker in this power range. There is only one large primary transformer; the smaller transformer powers only the 5VSB devices. The capacitors of the unit are good though as we could see only Matushita and a few Chemi-Con capacitors, all of them rated for 105C operation. There are four 12V lines on the PCB labeled as 12V1/12V2/12V3/12V4, however Corsair is using a unified OVP controller monitoring the 12V line as one instead of 4 smaller lines. There is no real reason to split the 12V line and risk overloading one smaller 12V line when all of the power for it comes from the same rectifier.
