A Detailed Look
The steel enclosure of the Kingwin LZP-1000 power supply features a black-matte finish and measures 180mm (7.1”) long. The Lazer Platinum Series PSUs use a single 140mm fan on the bottom for cooling.
The fan speed is automatically controlled by the onboard ECO Intelligent Thermal Control System. The LZP-1000 also incorporates a 2-way switch thermal control that allows selecting fanless mode at low to mid power or alternately having the variable speed fan running at all times.
Position #1: Dual voltage circuit with variable speed thermal control
Fan runs all the time; initially slow and will speed up as internal temperature increases.
Position #2: ECO Intelligent Thermal Control System (Default position)
Fan remains off at low to mid power; turns on as internal temperature increases.
In addition to the small 2-position red thermal control switch, the backside panel includes a power receptacle and On-Off switch along with an open grill structure that allows air to exhaust out of the power supply with minimal restriction and turbulence.
