The certificate lists no sample serial. The model code RPS0176 is the power-table model on Corsair's product page, so the entry matches. The test date is older than the 2024 SF1000, and the 80 PLUS list has no newer entry for it.

All lengths have a tolerance of 10 mm. PATA plugs are the 4-pin Molex plugs. The listing and the quick start guide say 12VHPWR, but the Overview calls the GPU cable a PCIe 5.1 12V-2x6 cable and the Corsair 12V-2x6 explainer lists it as a 12V-2x6 cable. The maker names it both ways, so it is stored as 16-pin PCIe. The page does not rate the cable.

The cable runs from two 8-pin Micro-Fit sockets on the PSU to a 12+4 pin plug, as the SF1000 gallery image and the Hardware Busters review show. It is a cable of its own, not an adapter on another cable.

The 16-24AWG range of the 12V-2x6 cable includes the sideband wires, so no gauge is stored for it. The ATX gauge is not stored because the Hardware Busters copy prints 16-20AWG and 310 mm. The 600W rating is printed next to the 12-pin cable. Corsair's 400 mm cable length is stored.8Reviewhwbusters.com/psus/corsair-sf1000-atx-v3-1-psu-reviewRead 15 October 2026Cables page: the review sample had 3 PCIe 6+2 cables, while Corsair's list and the Cybenetics report have 4. The review says the back panel has ten sockets and the 12V-2x6 cable uses 2 x 8-pin Micro-Fit sockets. It also says an SFX-to-ATX adapter is in the bundle.
