The Antec High Current Pro series consists of three PSUs with 750, 850 and 1200W capacity respectively. All three are manufactured by Delta but HCP-1200 uses a completely different design than the other two smaller models. HCP-1200 proves that the use of an 80mm cooling fan on the front of the PSU is not an outdated technique and with the right design, performance can be top notch and accompanied by low noise levels, like in this case. Even when I heavily stressed the PSU with 1200W load and over 50°C ambient it easily handled the situation and the small fan worked very efficiently and quiet.
The only thing that troubled me with this sample was the loose voltage regulation at minor rails, especially 3.3V. Another sample that I tested last year, with my previous set up , had much better voltage regulation. So maybe this review sample was not among the best performers of its batch. However voltage regulation at +12V, the most important rail, was close to 2%, a very good level for a 1200W PSU and the most amazing result of all was the crazy low ripple at +12V. I measured with different cables and scopes just to be sure that this wasn't a glitch but the readings remained the same. With such terrific ripple/noise suppression and high efficiency throughout 20% - 100% load this PSU definitely deserves its good reputation. On top of that it performed very well in the tough Advanced Transient Response Tests.

To wrap it up, if you have three or four high-end VGAs and you want the best available PSU money can buy today then you should put the Antec HCP-1200 on top of your list, at least until an 80PLUS Platinum contender manages to dethrone it or Antec/Delta decide to release a successor.
