SF1000 SFX 1000 W Platinum

The Corsair SF1000 is a 1000 W SFX power supply rated 80 PLUS Platinum. It uses a fully modular Type-5 Micro-Fit connector system and includes an SFX-to-ATX adapter bracket. A 92 mm PWM fan with Zero RPM mode handles cooling.

Suits compact high-power builds

This unit fits small-form-factor cases that accept a 125 mm deep SFX supply and need 1000 W of Platinum-rated power. Builds requiring a physically larger ATX chassis or a lower maximum wattage should consider other form factors.

ATX 3.1 and PCIe 5.1 ready

The power supply meets ATX 3.1 and PCIe 5.1 specifications, providing a native 12+4 pin GPU connector alongside four 6+2 pin PCIe cables. This compliance is the deciding factor for graphics cards that require the new connector standard.

Questions about this item

What does 1000 W mean for a system build?

It is the maximum continuous DC power the unit can deliver at up to 50 °C ambient, enough for high-end CPU and GPU combinations.

What does the 12+4 pin connector support?

The native 12+4 pin PCIe cable connects directly to ATX 3.1 and PCIe 5.1 graphics cards without an adapter.

Will this SFX unit fit a standard ATX case?

An SFX-to-ATX mounting bracket and screws are included so the 125 mm long unit can be secured in a regular ATX power-supply cutout.
