Corsair CS850M Power Supply Review

The Corsair CS850M is finished to a standard we would expect from Corsair. The lettering is white and green, on a black background.

The large fan is visible behind the black grill. We will have a closer look at the specifics of the fan when we open the unit.

The unit passed our ‘screwdriver’ stress test, which involves running a Philip’s head driver down the side of the chassis with weak to modest pressure. How often have you accidentally hit a power supply with some tools during a system build phase?

One side of the power supply is vented to aid with airflow. At the side is a power connector and switch.

The CS850M isn't a pure modular design, the main ATX and EPS cables are hardwired into the chassis. The modular panel only takes up about half the space of the panel at this side and is labeled as well for ease of install. The Peripheral and SATA cables are all 3+3 pin connectors and the PCI-E and 4+4 CPU connectors are 4+4 pin.

The power supply can deliver almost 850W to the +12V rail. Both +5V and +3.3V rails can deliver 25A each.
