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.

    That said, just to say, this Antec is made by Delta, and some of their new high end designs such as Antec Signature in their new PSU size (120mm rear fan) are also made by Delta, and are some of the highest rated power supplies going.

    Really, there are so many OEMs in this game under the same brand, you have to learn what you're looking at.

    The best site for this, bar none, is

    Sadly you can't even judge a PSU by its OEM.
    The same OEMs may build to vastly different standards - so even some chinese OEM that's been building firebombs for decades may get a contract to build a high-end PSU, and there's no real reason they wouldn't be able to do it, if they have the work force and know-how - both of which aren't that special in the PSU sector.

    In the end, don't buy by names or OEMs or brands or whatever - but look at as many reviews as possible, to verify that in every test the protection circuitry performed and noise was low, as well as the efficiency being the one that's indicated by the 80+ label.
    Even then there's a certain risk you end up with a monday's PSU, but odds are mostly in your favor..

    I completely agree with this post. It is just like asking, "Which brand video card do I buy?" The best one available in your price range, do your homework.
    Each PSU should be taken on its own merits. I always thought Kingwin power supplies look flashy but I would have bet they aren't that great. Then I find out some of the high end ones they've released in the last year are outstanding, from Superflower. I'm speaking in particular about the Gold Series.

    Platinum, too. Super Flower has a platinum platform.
    As always, I recommend

    I got the platinum one, its awesome by any standards! Reply

    Antec does not build most of their supplies. They are build by OEM's. My Antec is made by Sea Sonic for instance (great supply).

    Corsair does not build any of their supplies at all. And they actually use the same manufacturer that Antec uses for some of their supplies.

    Sorry you had a supply fail, it can happen with any brand. But saying you hate Antec yet love Corsair is kind of hypocritical. Kind of like saying you hate the Pontiac Vibe yet love the Toyota Matrix, when in fact they are the same car made in the same factory (well, back when they are being made anyway).

    before I buy another CX series Corsair.

    I bought 1 for a customer build, a CX500. It has coil whine.
    Yes I know coil whine is harmless but that's beside the point. It shouldn't make any noise other than the fan inside of it when it ramps up at a higher load/temp.

    Just because I've had a bad experience with a CX doesn't mean I'm not going to continue buying Corsair. I've got an HX850 and a TX650 right now happily chugging along. In the past I had an HX520 and a VX550. The VX550 eventually got killed after about 2 years of use (from Folding@home I suspect), but it was replaced under warranty. I'll still buy Corsairs in the future.

    My work rig has an Antec Neo Eco 620. No problems.
    Last customer build I put together I was trying to stay on the cheap and I went with the Rosewill Green series S2 620 after seeing the great review on Hardware Secrets. I've had no complaints of problems from my customer yet on that one (and I was leery of that one, being a Rosewill product....even though I knew internally it was an ATNG).

    Those points aside - you roll the dice with any psu. I've seen people on various sites/forums with dead Corsair's, Antec's, Enermax's, Silverstone's, etc [enter psu manufacturer here].

    As noted by other posters, Antec and Corsair aren't OEMs. Tom's has a great article listing all power supply sellers and the OEMs behind each line as well as how to figure out which power supply you actually have.

    I'll also take this opportunity to give Seasonic a thumbs up, based solely on personal experience.
  • Mr.T - Thursday, October 27, 2011 - link

    Oh wow, that Tom's article is really cool; It's nice to who the manufacturer actually is up the production chain.

    So it seems my PC Power&Cooling PSU was manufactured by Seasonic. Quite happy with that. I'll echo the Seasonic love then, as it's been running strong for 4 years now and it's not going anywhere either (thankfully, 750W is still plenty enough).

    Well, this article uses old information. I already did something like that in 2008 on ComputerBase (in German).

    Moreover you should know that some brands have a number, even if they are no real manufacturer (In Win e.g.). Today the UL number is unhelpfully. It's better to take a look at my articles. Usually I write something about the real ODM. Just like in this review.
