Antec HCP-1200 (High Current Pro 1200W) Overview

Our HCP (High Current Pro) sample arrived without any packaging, as it was one of the first samples and the final package contents weren't yet finalized. The shipping product includes the standard mounting screws and manual, plus the modular cables. Unlike the other PSUs in this roundup, Antec is using an 80mm fan from Sanyo Denki for cooling, reminiscent of old PC Power and Cooling designs. The case is 18cm long, typical for high wattage PSUs.

Cables and Connectors
Fixed/Modular Main 24-pin 65cm
ATX12V/EPS12V 4+4-pin 65cm / 8-pin 65cm
PCIe 4x 6/8-pin 55cm + 4x 6/8-pin 15cm
Peripheral 3x SATA 55-85cm / 3x SATA 55-85cm / 3x SATA 55-85cm / 3x SATA 55-85cm
3x Molex 55-85cm/ 3x Molex 55-85cm / 3x Molex 55-85cm + Floppy 15cm

Antec offers many SATA connectors but you can't conect all of them if you want to use all the Molex cables as well. The reason is there aren't enough sockets on the modular cabling system, so you're limited to choosing which cables you will use. Like Cooler Master Antec has eight PCIe connectors but they're longer and all have 6/8-pin heads. The two 8-pin connectors for CPUs are relatively common for 1200W PSUs, again just like the Cooler Master.

The 80mm fan is a ball bearing type with the product number 9AH0812P4G131 with a lifespan of 120,000hrs @ 40°C and up to 4500RPM. That sounds high, but as we will see later Antec manages to turn in some impressive results.

Antec has two PCBs with four (!) main caps from Rubycon. On the secondary side we can find more Rubycon caps and some all solid Nippon Chemi-Con caps as well. The transformer looks very small like the one from Cooler Master and there are very modern transistors with a low drain-source resistance. The protecion IC can be found on the second picture on the right sister PCB. The soldering quality is absolutely flawless.

    Corsair supplies are great and should have been included in any review. You make it sound like Corsair makes their own supplies but they don't. The AX series is made by Seasonic and based on the X series. Their other supplies are made either by CWT or Seasonic. Both of which make great supplies. So in reality any PSU comparison review must include supplies built by Seasonic and CWT. Reply

    Actually the AX1200 that is the king of the desktop power supplies right now is made by Flextronics. Corsair uses 2 different OEMs in their AX line up. This is why the AX1200 is the only model from the AX line I would consider. I already have a HX850 so would gain next to nothing with a AX850 Reply

    If a midtier review is being considered, please include some push/pull designs, or at least some high quality PSU's with an open grate in the front, and a fan in the back. Some of us are stuck with cases with wind tunnels like an antec p180 and the like, these do not lend well to a top/bottom mounted fan. Reply

    I've had 2 Antec Neos die on me the last three years. Hope no one else has my luck Reply

    Cougar has a CMX 1000w PSU, does anyone know how this compares to the GX 1050? Reply

    It's a little bit worse.

    Same fan, less 8-pin PCIe connectors, less efficiency.

    When you perform a more thorough review, please include the "Thermaltake ToughPower 80 Plus Power Supply". I just purchased one and would love to know how it stacks up vs. the competition.

    I'd also appreciate a bit more detail regarding the comment that a 1200 is overkill for most people. While I'm sure that's true, if you run some of the powersupply estimators availble online it's somewhat surprising how much power they suggest (I run two GTX 580's (not 3) to my HP ZR30W and they suggested a 1075 psu minimum with my setup.)

    Alot of people asked for ax1200 for good reason. Jonnyguru has a very complete test of this psu. It is rated very high on efficiency. No mention of it there but more than a few buyer reviews complain of coil whine. There is also a youtube vid displaying this. Still my choice and arrives tomorrow. Btw another site successfully ran four gtx 480s on it. Impressive but point of diminishing returns. Good luck with your choices. If this post stays up I will continue to visit this site. New here.

    Anandtech has run tests on mainstream PSUs recently - and runs more of them than on these kinds of PSUs. As far as people like you it's an obvious waste of time anyway, I doubt you'd actually read the articles if you found them. Reply
