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.
