A Detailed Look
The PC Power & Cooling Turbo-Cool 1200W power supply is big and heavy, just like you would expect. The enclosure measures just over 9″ long (230mm) and the PSU weighs almost 4kg. Even so, it was designed to fit in a standard ATX case (that is at least 20″ deep).
The Turbo-Cool 1200W power supply features a standard, high-quality PC Power & Cooling black matte paint job. The back panel contains an 80mm cooling fan, power receptacle, and On-Off switch. All the Turbo-Cool power supplies incorporate universal AC input (automatically adjusts to the AC line voltage) so there is no little red voltage selector switch.
The single 80mm cooling fan is made by Delta (EFB0812EH). This is the same high-speed, 3-blade fan used in the Turbo-Cool 1kW-SR. It features dual ball bearings and is rated for up to 5,000 rpm and 52 CFM at 12V. Using only three blades helps generate less noise but also does not develop as much static air pressure as an equivalent fan with more blades. To help minimize noise, the fan speed is automatically controlled by the internal component temperature (speeds up as the combined load and temperature increases).
The open honey comb grill on the front and small slots on one side allow air to flow into the power supply for cooling the internal components.
The Turbo-Cool 1200W power supply has a full complement of cables and connectors. All of the cables are hard-wired into the PSU chassis, which eliminates potential problems caused by the added resistance of modular cable connectors. At high power, even a little resistance can lower the delivered voltage and possibly cause overheating as contacts oxidize over time. The wiring harnesses measure approximately 21″ to 45″ long and are covered with black plastic mesh sleeving up to the first connector.
The Turbo-Cool 1200W power supply comes fitted with three 6-pin PCI-E connectors and three 8-pin PCI-E connectors (6-pin/2-pin split).
