Since this PSU features a single +12V rail, we do not have anything to say about its power distribution. The unit easily meets the 80 PLUS Platinum requirements even under sky high operating temperatures, which apply a far heavier stress on a small form factor PSU, compared to an ATX one. In the second test, we set the PSU to standby mode, dial full load and start it afterwards. In the last test, while the power supply is completely switched off (we cut off the power or switch the supply off through its power switch), we dial full load before restoring power. A PIC16F1824 MCU is used to control the fan speed profile. It is installed on the board that hosts the DC-DC converters for the minor rails. LONG LIFE AND SIMPLE DESIGN: High quality diodes emit very little heat and have a life span of up to 50,000 h. The SF300 is coated with a moisture resistant coating to protect the light from operating at optimal levels. Plug and Play. Simply plug into the power supply, no need to change the driver or fix it to any fixture. The slim design and cool operation make it perfect for growing anywhere, such as closets, shelves or countertop growing.

In the next set of tests, we measure the unit’s response in simpler transient load scenarios—during its power-on phase. The graph below depicts the cooling fan's average noise over the PSU's operating range, with an ambient temperature between 30°C and 32°C (86°F to 89.6°F).

The wire grill minimizes airflow restriction but is more expensive compared to just stamping the fan vent out of the housing so it’s nice to see Corsair go the extra mile on their first SFF PSU. The ATX specification (revision 1.4), along with CEC, ErP Lot 3 2014 and ErP Lot 6 2010/2013, states that the 5VSB standby supply efficiency should be as high as possible, recommending 75 percent or higher with 550mA, 1A, and 1.5A of load.

The bottom of the unit is a simple but elegant affair, with the Corsair logo stamped in the middle of some accent lines.
