Our load tests utilize a couple of FAST ATE active load testers and a variety of other equipment such as an oscilloscope, power conditioner, temperature probe and a power consumption meter. You can read more about our standard testing approach here.
The tests performed are based around six conceivable setups that are out there and progressively load down the PSU up to the power supply's limits or 1000W, whichever comes first. Since our test equipment's limits lower than that of the Antec HCP-1200, we can only test it to 1000W. Additionally, our equipment is only capable of creating four individual 12V loads. As such, each load created was shared between two rails on the power supply.
After running the Antec HCP-1200 through all of the tests, we were left with a bunch of rather impressive results. Voltage regulation stayed within 2% the entire time on ALL rails. The 12V rails were rock solid throughout all of the tests, with voltages never dropping more than .03V from start to finish. The 3.3V and 5V rails were nearly as impressive, with both rails showing a drop of .09V from beginning to end.
Ripple on the 12V rails were phenomenal. From the start, it was nearly impossible to even discern any noise on the oscilloscope. As the loads increased, ripple slowly crept up as well, reaching a maximum of 11mv peak to peak.
The HCP-1200 manages to sneak its way into passing the efficiency test for an 80Plus Gold rating. Usually we find that a power supply is cutting it close towards the end of the testing and might dip below the minimum efficiency required for a specific 80Plus certification. That isn't the case with the HCP-1200. It performs well at the beginning and the end, but cuts it real close at 50% load. The HCP-1200 edges its ways over the minimum 90% efficiency required to achieve the Gold rating.
Antec has brought a fantastic power supply to the market with the HCP-1200. The unit performs on a nearly flawless level from start to finish, is built really well, and is packed full of features. You simply couldn't ask for more out of the HCP-1200. It would be nearly impossible to find a better 1200W power supply and we highly recommend that you consider the HCP-1200 should you require that much power. We'd gladly name the HCP-1200 the Crème de la Crème of power supplies, but it has some serious competition. In fact, this unit is on the exact same level as the recently reviewed Corsair AX1200.
Taking a look at the two units, we tried hard to find a way to value one over the other, but no matter how we did it, the final score always came out the same. The difference between the two is going to come down to personal preference. Do you want multiple 12V rails or a single rail? Do you want fully modular or partially modular? Performance is so marginally better on the HCP-1200 that you'd never see a real world difference, but the Corsair has a longer warranty. Prices are the same. Are you an Antec fan boy or a Corsair fan boy? No matter how you choose, you can't go wrong.
