Supremo M1 Gold 550W

Developed with maximum reliability and rock stable power delivery in mind new Supremo M1 Gold 550W is built using only premium-grade components. Advanced layout includes Japanese main capacitor, Taiwanese solid-state capacitors as well as DC-DC converters. The unit is capable of reaching phenomenal efficiency up to 91% thus fulfilling 80PLUS®Gold Certificate requirements.

The result of high build quality is 550W of clean, continuous power, tight voltage regulation and outstanding ripple suppression. Powerful single +12V line delivers up to 45.9A (550W) for demanding systems including workstations and gaming PC’s with high-end GPU configuration and overclocked CPUs.

Extremely high efficiency allowed us to implement whisper-quiet cooling system. While operating at low to medium loads the built-in 135mm fan spins at 500rpm and even at maximum output the rotation speed is only 1200RPM.

Built-in safety features protect the PSU and the components against surges, over-power, over-voltage, temperature etc. The Supremo M1 is also fully compatible with Intel Haswell C6/C7 modes, is ErP Lot 2013 compliant and can be used for building Energy Star 6 compliant PC systems.

Elegant, Pure Black finish adds professional look while semi-modular flat cables make it easy to route and arrange them around the case. The PSU is equipped with plenty of connectors for all modern hardware components including two PCI-E 6+2 pin for multi-GPU configurations.

Supremo M1 Gold 550W is backed with 5-year warranty for end-users upon registering the unit within 30 days from purchase.
