Corsair SF1000 Platinum (2024) PSU Review

Rating: 9.0.

Today we look at something rather unusual and exciting – one of the smallest 1000 Watt power supplies I have ever seen. This unit measures only 100mm x 125mm x 63.5mm so will fit into even the smallest chassis on the market today. Corsair have updated this platform to the latest ATX 3.1 standards, and it is a fully modular Platinum rated power supply with a 7 year warranty.

Previously, Corsair had their Gold certified SF1000L on the market, so for this new version Corsair have improved efficiency levels while making the power supply smaller. On paper this is some achievement, so we can't wait to see how it holds up in our testing later in the review.
