The short version
The SF750 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.

PositiveAn owner describes a custom two-piece fan grille her boyfriend designed for the SF750, making the fan sit flush and opening the grid to cut fan noise under heavy loads.

Common questions
Does the SF750 fit a standard ATX case?
It is an SFX unit, so it needs an SFX-to-ATX adapter bracket to mount in a standard ATX power supply bay.
What warranty does the Corsair SF750 carry?
The maker lists a 7-year warranty on its product page. Warranty terms can differ by region.
