Antec HCG 750W: Built for Gamers?by Martin Kaffei on April 12, 2011 8:20 PM EST
Package, Power Rating, and Fan
Like most PSUs, the package includes a power cord, four screws, and a small user manual. The PSU also comes with a separate cover to protect it from dust and scratches. Besides the 80 Plus Bronze and SLI-Ready logo, the HCG has 40A +12V rails, active PFC, all important safety functions, and a 5-year warranty. The High Current Gamer name is obviously in reference to the four 12V rails, which allow gamers to use the various cables without worrying about how much power they're drawing from any single rail. The housing is 180mm long, so you'll need enough space for it, and all cables are fixed.
If we trust those indications the load for one +12V rail could be up to 40A. The +12V rails are able to deliver the full output power in a peak situation while the continuous power is 750W. A specified temperature for the various ratings would have been nice, but we will verify the manufacturer information at room temperature. +3.3V and +5V are rated at 150W and/or 25A each. That's more than enough for a lot of HDD or SDD drives.
There's a large fan, but interestingly it's also covered by a large foil. We are not sure if this will help with airflow, but presumably Antec tested with and without the foil in place. The ADDA fan has the aforementioned ball bearings, with the exact model being ADN512UB-A90. This 135mm fan has nine blades and runs off 0.44A. It is not PWM controlled, unlike in most other Antec PSUs. The rated airflow of 82CFM should be enough to keep the interior cool.
