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.

    Wow, sorry to hear that but it kinda sounds like luck of the draw to me. I've used Antec products for quite a while and they've always been high quality.
    My Antec 650W Blue PSU has been doing well for 3 years and I expect it to continue for at least another 3, probably more.

    I've always used WD hard drives, until I had a 500GB green drive fail on me. Now I am skeptical to give them another chance, much like you. I suppose I would give them another shot. On the other hand, the first Foxconn mobo I bought was a piece of crap and I won't bother with that brand anymore.

    Trust is something I've always had in Antec products. However PSU dealers like Antec are dependent on the quality of the OEM manufacturer. So, yeah I agree that some of the better Antec and Corsair units have been Seasonic in origin.

    The original Seasonic X-series (X-650, etc.) used PWM fans. I believe the new ones (X-660, etc.) use non-PWM fans. Was the entire rationale for the "new" X-series products just to avoid paying royalties on yet another patent that should never have been issued?
  • Martin Kaffei - Wednesday, October 26, 2011 - link

    The new X-Series versions have an improved technology (better MOSFETs, some layout changes, larger heatsinks) too. So I wouldn't say they made new products just because they didn't want to pay for PWM.

    The Seasonic X-Series is great, since they use Sanyo Denki fans and a semi-passive cooling. Even if there is no more PWM the fan (and fan regulation) is still satisfying.

    Btw. Corsair AX (X-750 design) has no PWM. There is definitely a patent for PWM fans in power supplies. Seasonic paid, Corsair not.

    Nice article, but could you put captions on your photos? They are nice but not always clear what they are highlighting. Sorry for being nitpicky :P

    Thanks for the review of this item (though I'm not in the market for that much power, prefer the 500-600W range which is sufficient for my single CPU/GPU configurations).
    I am going to be buying a new PSU around Christmas and my two current favorites are the Seasonic X-560 or the new be quiet! Straight Power E9 CM. Are you going to be able to review the be quiet? It has a larger fan, is cheaper. The Seasonic has the advantage of being proven and semi-passive. I'd be interested to know how they fair against each other. :-)

    Couldn't find a review on the unit you're looking for but it sounds promising, hre's a review on its smaller 400 W sibling:
  • Death666Angel - Thursday, October 27, 2011 - link

    Thanks for that, but the review is of the E8, which is the predecessor to the E9 which has just been released. The E8 is just bronze/silver, whereas the E9 is all the way gold as far as I can tell. :-)

    Two references to HCG-750, which is (probably?) a different product.
  • JarredWalton - Wednesday, October 26, 2011 - link

    Oops... my bad in editing. High Current Gamer is definitely a different product, though I'm not sure if a 750W model exists. Anyway, I've replaced the references with the HCP. Thanks!
  • buzznut - Thursday, October 27, 2011 - link

    Yeah. high current gamer also by Antec. An easy enough mistake.
