Antec HCP-750 belongs to Antec's top of the line series, High Current Pro. This series includes the mighty HCP-1200, a PSU that gives a really hard time not only to the competition but also to the other two members of the HCP series, since these models are expected to follow its lead, performance wise. Although HCP-750 is not a record breaker, it is a solid performer with lots of capabilities. It is definitely not as good as the HCP-1200, which plays in an other category by itself. We saw very low heat levels on the HCP-750, so in a case with good airflow even at full load its fan won't be annoying. Efficiency at normal loads is very high, ripple levels are kept low and it has lots of connectors on its modular panel. If you buy an extra PCIe cable yourself then you will be able to connect three graphics cards to it, not high-end though since the PSU's capacity is a limiting factor here. The noteworthy downfalls I managed to find were efficiency at very low loads, the somehow loose voltage regulation at 3.3V and that the PSU is a few bucks more expensive than the direct competition (e.g. Corsair AX750).

Bottom line is that you can't go wrong with the Antec HCP-750. It is a PSU with lots of features, good performance and uses top notch components. If 750W cover your needs and you want something of top quality then you should include the HCP-750 on your "things to buy" list.
