The Corsair SF1000 is a really small power supply measuring only 125mm x 100mm x 63.5mm (WxHxD). It is finished to a high standard and is neutral by colour, all black with accents of silver/white on the lettering.
To give you an idea of just how small this unit is – you can see it above, resting on the Antec HCG1000 unit we reviewed recently.
One side of the unit is home to the power connector and switch, alongside a vented panel to aid airflow.
The other side houses the modular bay, split into three rows, all labelled for ease of use during the install phase.
The power sticker shows that the unit can deliver 83.3A to the +12V rail, along with 20A to both minor +3.3V and +5V rails. Corsair have removed the -12V rail from this PSU which helps increase efficiency and remove some costs. This rail is not really needed in 2024 so there is no problem.
