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./"
