Appearance, Cables, and Connectors

In contrast to most other products the housing of the HCP-750 is coated in anthracite. The fan grille has a pseudo-octagon shape and the front has protruding connector sockets in red and black. The fan is noticeably smaller than the case. The ventilation holes are (as usual) honeycombed and relatively small. This is advantageous for ensuring EMI is within spec but disadvantageous for cooling. A small power switch is located directly next to the power input.

Overall, the build quality of the case is flawless. On almost all sides of the PSU Antec logos can be found. At 180mm long and considering the power rating and modular connector system, the power supply is an average size. Under the cable sleeving you can still see the yellow, orange and red wires.

Cables and Connectors


Main 24-pin 55cm fixed
ATX12V/EPS12V 4+4-pin 65cm fixed, 8-pin 65cm modular
PCIe 2x 6/8-pin (55, 70 cm) fixed, 2x 6/8-pin (55, 70 cm) modular
Peripheral 3x SATA (55, 70, 85 cm), 3x SATA (55, 70, 85 cm), 3x SATA (55, 70, 85 cm) all modular
3x HDD (55, 70, 85 cm), 3x HDD, 1x FDD (55, 70, 85, 100 cm) all modular

With four 6/8-pin PCIe connectors the power supply is relatively well equipped. Despite the somewhat more generous cable cross-section it would have been better to split the PCIe connectors onto four separate cables, though that can also create more cable clutter within a case if you need to use all the cables.

The 24-pin, the 4+4-pin 12V AUX, and two of the PCIe connectors are permanently installed at the power supply. This is quite understandable, since this power supply will typically be used with powerful graphics cards. The HCP-750 has six Molex connectors, which should be sufficient for the vast majority of builds. The fact that Antec offers two 8-pin connectors for server motherboards is another great idea. A fixed FDD connector is included in the configuration as well, which will still be useful for some builds.

    "Antec has patented the use of PWM fans in PC power supplies"

    And some patent office granted it? Has the world gone mad...patents should only be granted for matters which are innovative and non-obvious. Use of PWM fans in power supplies is completely obvious.

    On that basis, I am not buying an Antec power supply. Fortunately there are plenty of other equally good makes

    *Hopefully* it's a misprint and they just patented some specific PWM control circuit or something, but I'm not optimistic.

    Oh well, I'm off to patent the idea of replacing the processor in a computer with a faster one.

    Didn't someone else patent 140mm fans in PSU's, which is why people marketed their 140mm fans as 139mm?
    Funny nobody patented the fact of putting a fan on a PSU in the first place...

    I have a weird feeling it was Zalman, but I'm not 100% on that.

    It's HEC, who also owns Cougar.

    "Antec Antec" in the headline and then "Anctec" in the first line....
  • Mumrik - Wednesday, October 26, 2011 - link

    "Anctec" is only on the frontpage....

    Fixed! Thanks a lot.

    before I will trust an Antec PSU in a system again.

    In 10+ years of building systems, I have had two times where I had a power supply failure, that took out other components at the same time. Believe it or not, it wasn't back in the Powmax days, either.

    Both times, Antec PSU's fried, and took out my motherboard with them. Shoot, if I had wanted that kind of performance, I would have kept the Powmax PSU in the case!

    Trust is earned, Antec......and you have not done so. Think I'll stick with Corsair, for now.

    Some Corsairs are made by Channel Well, the exact OEM that made plenty of Antecs several years back. Though, really, the problem was the Fuhjyyu capacitors. They were absolute garbage and used in a lot of Channel Well designs, including lots of Antecs.

    When you see the inside of a Channel Well, it's usually obvious, because they use this green crinkly tape around the transformer.

    I go to the desired source and buy Seasonic power supplies. Although I do have a Corsair HX520 which is Seasonic built.

    I just bought myself a Seasonic X-660. It was costly, but I don't want to fuck about when it comes to power supplies... and it does have a Sanyo Denki fan ;)
