PSU: Be Quiet! SFX Power 350 W
Naturally, a case this small requires an SFX-based power supply. There are a number of these available, though they aren't particularly common. Our U.S. team has had good luck with SilverStone's offerings in the past. But in Germany, be quiet! is a familiar vendor. The team there went with that company's BN134, a 350 W, 80 PLUS-certified unit with a PCI Express auxiliary connector for discrete graphics.

Opening be quiet!'s SFX Power 350 Watt reveals the power supply itself, as well as a power cable, manual, screws, and cable ties. In short, it doesn't leave you wanting for anything.
The cables are sleeved well and long enough for our installation.
The SFX Power 350’s fan is audible when the system is under full load. However, most of that noise is redirected back into the case, so you won't hear the power supply over the other fans in taxing situations. If you're only using an APU, and no discrete graphics card, the PSU shouldn't be audible at all.
