Fully modular 1000 W ATX 3.1 unit with 80 Plus Gold efficiency, a 120 mm FDB fan, 140 mm depth and native 12V-2x6 PCIe 5.0 cable
Model ATX 3.1 80+ Gold (1000W) Black
This Super Flower Combat FG unit delivers 1000 W through a single +12 V rail and meets the ATX 3.1 and PCIe 5.0 specifications. It is 80 PLUS Gold certified with measured efficiencies of 87% at 20% load, 90% at 50% load and 87% at 100% load. The fully modular design uses ribbon cables and includes a native 12V-2x6 connector alongside five 6+2 pin PCIe plugs.
The 140 mm depth fits many compact chassis, while the nine SATA connectors support multiple drives. Systems that require more than two CPU power connectors or more than six total PCIe connections will need a different unit. Buyers who want a shorter depth or a higher efficiency rating should look elsewhere.
Under continuous load the single 120 mm fluid dynamic bearing fan ramps to maintain thermal limits while the 100% Japanese capacitors keep voltage regulation tight. The active PFC and full-range 100–240 V input maintain stable operation across varying mains conditions. Efficiency stays at the certified 87% level at full rated load rather than dropping off after a short burst.

Other versions of this model
The power supply is 140 mm long, so your chassis must provide at least that much depth behind the mounting bracket.
The included dual 6+2-pin to 12V-2x6 cable is built for PCIe 5.0 GPUs and plugs directly into the 16-pin connector.
With the 120 mm FDB fan, listen for startup spin-up; it should stay silent at low load and ramp up only when temperature rises.
