Some station really needs to put “Lost In Space” back in syndication. It was every bit as surreal and hokey as “Batman”, and would definitely be a better choice for a station like SyFy than their “Dinogator” stuff. There was nothing quite like Dr. Smith wailing “Will…oh, Will….” in feigned remorse right after he had tried feeding the poor kid to a bunch of aliens in order to save his own hide. Ah, and the robot….flailing his arms wildly while spinning in circles saying “Danger! Danger!”. Oddly enough, that is exactly the same thing I do when I see a “budget” no name PSU.

So, why am I not doing my robot imitation with a PSU from an unknown company called “High Power” on my bench? Simple, High Power is actually the retail arm of well known OEM manufacturer Sirfa. Sirfa can actually lay claim to being the first manufacturer of 800, 1000 and 1200W 80-PLUS Platinum PSUs, as well as first with 1000, 1200 and 1350W Gold. They have also been the OEM for some highly respected PSUs. I have owned several Sirfa/High Power manufactured PSUs over the years and, whether you realize it or not, you may well have, also. You may not know the High Power name, but the track record is definitely there.

The High Power Astro GD-750 (or AGD-750) takes all of this innovation and puts it into one 80-PLUS Gold package. The High Power Astro GD-750 is semi-modular and boasts a single 744W 12V+ rail along with semi-passive Intelligent Cooling. The AGD-750 takes the reasonable approach to semi-modular, with 24-pin, 8-pin and 4+4-pin permanently attached, along with one PCIe, and ten SATA, four molex and four 6+2-pin PCIe, all modular using flat cables. Internally, the AGD-750 uses solid Japanese capacitors, along with Digital VRM and DC-DC converter on the minor rails for solid power delivery. The 135mm fan uses semi-passive cooling, with no activity when loads are below 25% for the utmost in quiet and efficiency. On the rear of the AGD-750, there is an active real-time power meter to monitor usage and load.
