Yes it does. The Bricasti M1 uses the popular XMOS input chip that's powered from the host device.

I know several M1 owners who use a variety of devices to inject a clean 5V supply rather than rely on the often noisy motherboard supply from their mac / pc.

I'm using a JCAT PCIe USB card that provides an external dc input socket, so for me it was a simple matter of powering it with a discrete low noise linear regulator, which uses a two stage series + shunt design with some RF filtering. My PC is also powered from a discrete linear supply and the internal SSD's are additionally powered by linear shunt regulators. The PC is also fan-less and uses a low power i7 quad core processor. Under normal operation the total input power is roughly 15 Watts.
