Antec HCP-750 Overview and Specifications

Today we take a look at the Antec HCP-750. Let's start with the delivery contents. Apart from the PSU itself the package includes a power cable, four screws to mount the device in the PC case, a short user guide, and the modular connectors in a separate bag. The HCP is protected from dust and dirt by a bag during shipping. The product features include 80 Plus Gold Certification, the 16-AWG connection cables (large wire cross-section), the 135mm PWM fan, and the gilded connectors. In addition Antec ofers a 5-year warranty, which is a common feature for a product like this.

The HCP-750 has four +12V outputs, each of which can be loaded with 40A according to the manufacturer. Almost the full power is provided here because of the DC-to-DC VRM. The +5V and +3.3V combined output is 150W. +5VSB can handle 3A (or 15W), and the label shows the various safety certifications. Antec products can be bought all over the world, so there are many country-specific requirements.

Antec uses a DC fan from ADDA with the model number ADN512UB-A9B. This one is controlled via PWM, so the duty cycle will be modulated. As a Sanyo Denki employee reported at Computex 2011, PWM is much better for the fan than voltage control. However, it should be mentioned that Antec has patented the use of PWM fans in PC power supplies, which complicates their use for other manufacturers. The fan needs 0.44A from the +12V output, and the nine fan blades pictured above are pretty well made.

    "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 ;)
