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.

Questions about this item

Does my case need to accept a 140 mm long ATX 3.1 power supply?

Yes, the unit is 140 mm deep, so the chassis must support at least that length for a proper fit.

Can I use the native 12V-2x6 cable with a PCIe 5.1 graphics card while keeping my older PCIe 6+2 pin cables for other devices?

The fully modular design includes a native 12V-2x6 cable for PCIe 5.1 cards and additional PCIe cables for legacy connectors, all detachable.

How do I confirm the fan is running in its low-noise mode after installation?

The 120 mm fluid dynamic bearing fan spins up under load; you can verify operation by listening for airflow or checking RPM via motherboard monitoring software.
