SFX-L 1200 W Platinum power supply

This SFX-L unit delivers 1200 W of continuous power for compact systems that demand high output. It fits builds limited to 130 mm depth while providing a fully modular cable set. The single 120 mm FDB fan handles thermal loads at this wattage tier. It targets small-form-factor workstations and high-end gaming rigs.

80 PLUS Platinum efficiency limits

The 80 PLUS Platinum certification guarantees 89% to 91% overall efficiency across typical loads. Active PFC maintains a power factor above .9 at full load, reducing strain on the mains supply. Input range spans 90 to 264 V at 47 to 63 Hz for worldwide compatibility. These figures define the practical ceiling for wall-socket draw and heat output.

Single +12 V rail rated at 100 A

The +12 V rail supplies up to 100 A, which is the decisive spec for modern GPU and CPU power delivery. Minor rails provide 20 A at 3.3 V, 20 A at 5 V, 3.0 A at 5 VSB and .3 A at -12 V. Protection includes OCP, OPP, OVP, SCP and OTP. MTBF is rated at 100000 hours.
