Manufacturer description

The PicoPSU design features a "snap-in" design removing the need for a ATX cable. The PicoPSU connects directly to the ATX power connector on your motherboard saving space and eliminating 24 unnecessary wires. This provides a cleaner environment for your components and reduces the amount of used space inside of your chassis to improve air flow.
