Corsair SF1000 ATX v3.1 PSU Review

The Corsair SF1000 is among the strongest SFX PSUs available in the market today, offering top performance, high efficiency and it is also ATX v3.1 compliant. 

The Corsair SF1000 will be included in my best ATX v3.x & PCIe 5.x PSU picks article.

It was high time for Corsair to enrich its SF line with stronger and ATX v3.1 (SFX12V 4.1) compliant members. The long wait was because Corsair wanted to ensure that the new SFX units would continue the legacy of the previous models, which were among the best in this market segment. The SF1000, besides being one of the strongest SFX PSUs available in today’s market, is also the best performing.

To increase efficiency, make the platform more reliable, and save money, Corsair decided to ditch the -12V rail in these PSUs. This was a wise move since no PC part requires this rail anymore, which is a remnant of the past. Every PSU manufacturer should eliminate this useless rail as soon as possible.

I have evaluated so far the following SFX and SFX-L PSUs:
