Appearance, Cables and Connectors

Like the Corsair AX 750W, this model has a simple black finish. On both sides of the PSU there are Corsair logos with the product name. With a usual fan grille and a small power switch it looks "boringly normal" in contrast to Antec's HCG series. The surface is scratch-resistant and those honeycombed ventilation holes at the back are relatively small, which is good for EMI shielding but may hinder airflow slightly.

Corsair has a nicely fashioned hole for the cables exiting the casing, which will protect the black sleeving and cables against damages from rubbing against the case. Cheap power supplies often have sharp-edged outputs that can destroy the sleeving or in some cases even damage the wires, so the protective cover around the edge is appreciated.

The TX750 comes with a large number of fixed cables. You'll want to make sure that your case has enough space to store unused cables, so you don't obstruct the airflow. If your case has a window, the fixed cabling can also look untidy, which is why most users with windows cases prefer modular cables.

Cables and Connectors
Fixed Main 24-pin 60cm
ATX12V/EPS12V 4+4-pin 60cm
PCIe 4x 6/8-pin 60cm
Peripheral 4x SATA 40-85cm / 4x SATA 40-85cm
4x Molex 40-85cm / 4x Molex 40-85cm (+ FDD adapter 15cm)

The Corsair TX750 V2 has fewer SATA connectors than the Antec HCG 750W, though the length of both mainboard cables (24-pin and 4+4-pin) are equal. Like Seasonic, Corsair offers an FDD adapter in case you need it. In total, the TX750 supports eight SATA and eight Molex connectors, which is more than enough to support most PC configurations. This PSU is also SLI and CrossFire certified.

    SMH. Guys, please learn what the hell you are talking about. There is no difference AT ALL in performance from a single rail unit and a multiple rail unit.

    The only difference is how the over current protection functions. There is none of this balancing BS you speak of.

    You guys call yourselves computer gurus, and meanwhile don't have a clue what you are talking about. GJGJ

    I've tried two different PSUs and two graphics cards, but any combination have resulted in the PSU squealing when I use the graphics card.It's especially prudent in ATI Tool and when I have high FPS in menus or old games. So now i'm on the lookout for a psu that does not squeal when the gpu or the cpu is doing bad stuff.

    I hear even the latest Corsair HX850W are squealing.

    Have you tested this PSU for squealing? What 3d card did you use?

    I have tested with
    Mist 650W rev 3.5
    Mist 650W rev 4.0
    xfx geforce gtx 285
    evga geforce gtx 470

    I read MSI once made non-squealing graphics cards, but I haven't heard anything since.
