160 watts is plenty but i need a power supply that can be used on a full sized desktop type motherboard not a mini motherboard it must also supply power to multiple peripherals and drives. basically i am building an entire desktop system into the robotics project.
Why do you think the picoPSU won't work?
Do you have a graphics card that draws power?
Or do you have more than one optical drive or more than one hard drive?
Or do you use a multi-CPU motherboard that needs more than one CPU power lead?
Mini motherboards and desktop motherboards all use the same 24-pin power connector. (Some of the picoPSUs come with 20-pin connectors, and may need an adapter -- that's true even for mini-ITX form factor motherboards.)
