The SF1000 is Corsair's small-form-factor Platinum power supply, updated to ATX 3.1 and PCIe 5.1. It is fully modular with individually sleeved Type 5 cables, a 92 mm fluid dynamic bearing fan with Zero RPM mode and a 12VHPWR cable for current graphics cards. It suits compact builds that still need a high-wattage supply. Corsair's page does not state its length, and SFX cases vary in clearance.

It is an SFX unit, so it needs an SFX-to-ATX adapter bracket to mount in a standard ATX power supply bay.
The maker lists a 7-year warranty on its product page. Warranty terms can differ by region.
