After countless requests from our customers, we have made an adapter that lets you use an hp slimline power supply with a motherboard that has a normal atx connector. This converter plugs into your small 24 pin atx connector on your hp slimline power supply and converts it to a 20 or 24 pin normal atx connector. This little adapter comes in handy when you change out your hp slimline motherboard and do not want to replace your power supply. It also makes the hp slimline power supply compatible with other standard computers.
