Super Flower SF-1200Z12FG 1200W power supply

1200 W ATX 3.1 power supply

The Super Flower SF-1200Z12FG delivers 1200 W of continuous output through a single +12 V rail and meets the ATX 3.1 specification. It is fully modular with embossed ribbon cables and uses a 120 mm fluid dynamic bearing fan. Cybenetics Platinum certification confirms high efficiency and low noise. The unit accepts 100 to 240 V input at 50 or 60 Hz.

Suits high-power builds with modern GPUs

Builders assembling workstations or enthusiast desktops that demand strong transient response and PCIe 5.1-ready connectors will benefit from the native 12V-2x6 cable and Platinum efficiency. Systems that require only modest wattage or have very limited case depth should consider a lower-capacity unit instead. The 140 mm length fits many mid-tower layouts but clearance must be verified.

Handles sustained 1200 W loads with headroom

The single-rail design and Japanese capacitors keep voltage regulation tight during heavy, sustained draws such as rendering or compute workloads. Efficiency remains above 90 % across typical operating ranges, reducing waste heat. The 120 mm fan provides cooling without excessive noise at full load. Extreme multi-GPU configurations pushing beyond the rated maximum will exceed the unit's capacity.
