Corsair SF1000 ATX 3.1 PCIe 5.0 Platinum Power Supply Review

Corsair has somehow managed to stay at the top of the market for a very long time now, with many of the most popular and best products in multiple categories, with incredible gaming monitors, desks, chairs, keyboards, mice, headsets, SSDs, power supplies, coolers, cameras, and so much more. There’s no sign of them slowing down either, actually, quite the opposite, as we saw at Computex 2024, they’ve got a lot of new stuff on the way. One of their most exciting new products, however, is their ATX 3.1 and PCIe 5.1 certified 80 Plus Platinum power supply, which can deliver incredible efficiency, 1000w of power, and all in a very compact true-SFX form factor.

SFX PSUs are getting incredibly powerful these days, and having 1000W in SFX is simply amazing, especially with both 80 Plus Platinum and Cybernetics Platinum certification, fully modular cables, a zero RPM fan mode below 400 watts, and 12VHPWR support; you really couldn’t ask for much more from a power supply than what’s on offer here.

Features of the Toughpower SFX Series

• 80 PLUS Platinum rated efficiency
• ATX 3.1 compliant, supporting PCIe 5.1
• Fully modular, Type-5 Micro-Fit PSU connectors
• 92mm PWM cooling fan with Zero RPM mode

What Corsair Had to Say

The ATX 3.1 standard demands a high level of reliability and power efficiency. While many CORSAIR PSUs meet these requirements, SF Series PSUs are formally certified for ATX 3.1 compliance. PCIe 5.1 12VHPWR GPU cable included for use with modern graphics cards such as the NVIDIA^® GeForce RTX™ 40 Series.
