Reviews - Antec High Current Pro 1200W

Today I have Antec's newest power supply. A power supply so new.. it won't be available until October. So new.. the unit I received didn't even come in a retail box. But at least I got a PDF representation of a box! The power supply we're looking at today is the Antec High Current Pro 1200W, or HCP 1200 for short.

I'm not really sure where the name "high current" comes from. The OCP (over current protection) on the +12V rails of this model is supposedly set to 30A where the OCP on a True Power Quattro +12V rail is set to 38A, and the total +12V capability is 99A while the True Power Quattro's +12V rail is capable of 100A, so if any Antec power supply should be called "High Current", it's the True Power Quattro. But they did need to call this power supply something different since it's a completely different beast from the True Power Quattro., so I guess High Current Pro is going to have to do.

On the back of the box, we have some bullet points:

There's some good information here. One thing I'm a bit confused about is the sixth bullet point. "10-pin modular connector"?

The only modular connectors on the Antec HCP 1200 are either 6-pin or 8-pin. There are no 10-pin power connectors. Hmm....

On one of the sides of the box there is a whole panel of little logos that represent different features of the power supply:

Wow... Ok. I think most of the jonnyGURU.com audience knows what most of these things mean. The only thing here that we're not used to seeing yet is the EuP 2010 and that's starting to pop up on a few power supply boxes these days. It just means that the PSU meets the requirements of the E.U. for an Energy Using Product.

Another one of the logos shown above points out that this PSU has eight +12V rails. What's the point of that? Well... the more +12V rails you have, the fewer connectors you'll have on each of these rails. This allows the PSU to have the safety of over current protection on the rails, yet still avoid the risk of too many devices on a particular rail, causing the PSU to shut down unexpectedly. Let's have a look at the DC output table as it appears on the power supply's label:

There are so many +12V rails, they had to move the specifications for the +5V, +3.3V, -12V and +5VSB onto a second table! We break out the whole DC output table in an easier to read format below:

You'll also note that the side panel shows there are two 8-pin CPU connectors. We actually have one 8-pin and two 4-pins that can be combined to make a second 8-pin. This is what makes the power supply EPS12V 2.92 compatible. Here's the break down of all the cables that come with the HCP 1200. You'll see a good deal of them are fixed while several more are modular. This is what Antec means by "Hybrid Cable Management". In the below table we also state which +12V rail a particular connector uses:

Now, you may notice that there is plenty of juice to go around for each of most of the connectors. For example: Each CPU power connector has it's own +12V rail. The two +12V wires on the 24-pin power connector gets it's own +12V rail. There are only two PCIe connectors to a +12V rail. Clearly this is insane overkill. Except for one exception.. +12V4.

You'll notice that ALL of the peripheral and SATA power connectors, fixed and modular, are on +12V4. There are a total of 22 connectors on one +12V rail. Sounds like potential trouble, right? Well, no... not really. Fans use less than 1A each and hard drive use less than 2A each, so even if you had 22 devices plugged into this one rail, it's not likely that you'll overload the rail.

Ok.. ok.. Let's say that you DO overload the rail, and you have all of this untapped power on these other rails that you wish you could use. Well, as long as you're not running four high end graphics cards requiring a total of 8 PCIe power connectors, you can actually use the peripheral/SATA power connectors on the +12V7 and +12V8! Check it out:

Sweet! They've got us covered for anything!

Finally, let's have a look at the exhaust end of the power supply:

Here we see we have a power switch (yay!) and an 80MM exhaust fan. Our instinct reaction to 80MM fans on power supplies is that they're going to be loud, but one of the panels on the box assures us that this fan only gets loud when the going gets tough:

According to this chart, the PSU is hardly going to spin unless you're at about 50% of the PSU's capability.. and if you're pulling that much juice, you're probably doing stuff with your graphics cards and GPU to kick the fans up on those a lot louder than this PSU fan! But we'll see in the load tests on the next page. If the fan gets unusually loud, I'll let you know.
