A Detailed Look
The Zalman ZM750-HP 750W power supply features a black matte finish and the enclosure measures 165mm (6.5”) deep. It uses a single 120mm fan on the bottom and has a power receptacle and master On-Off switch mounted on the back panel.
The fan speed is automatically controlled by the internal component temperature (speeds up as the combined load and temperature increases). The dual ball bearing Adda fan (AD1212MB-A71GL) is rated for up to 80.5 CFM at 2,050 rpm and 38.0 dBA at 12V.
The open honey comb grill on the back and small slot openings on the front allows air to exhaust out of the power supply for cooling all the internal components.
