PSU for Thin Mini ITX mobo.

Hello. Building a small PC with "Asus Q87T/CSM Thin Mini ITX LGA1150 Motherboard". The System Builder recommends all kinds of PSUs, but I doubt they will work because this mobo needs only 19V via a 2-pin ATX 19V cable. Can a modular ATX PSU be used for this? If not, any other suggestions?

The System Builder isn't even able to filter PSU's by available EPS/CPU power connectors yet, so in funky situations like this it's best to not trust it fully.

The motherboard receives power via a 19V DC port that is on the I/O shield next to one of the USB sets. I'm having trouble finding any documentation (in my short google searches, at least) for how to utilize those 2-pin power connectors, but they definitely won't work with a standard ATX supply, because those only provide 12V.

Your best bet is to find a 19V laptop-style power supply with sufficient power handling. Otherwise, you can find what are essentially jumper kits that can connect to ATX12V PSUs, but those will usually be much more expensive than the power brick option.

Thank you for clearing up the confusion! Sounds like a laptop power brick should work.
