I’m wondering if I can use a Keces P3 to power my NUC/Roon and a GigaFOIL? I see some mention using a P8 for the NUC and P3 for the GigaFOIL but isn’t that overkill since the P3 has two outputs? Or is 16V not enough to power a fan-less NUC?
Not the voltage where you might run into issues…it’s the current (A) that the units demand where the issues might be. NUC will run ok on 12-19volts but should be supplied ~3.5A
When the later NUC models need to go into Turbo mode their power requirements jump quite a lot more than gen 7 or 8 models. Get a PSU as close to 19v as you can with very good current delivery. While a P3 will work it will only deliver a maximum 3 amps at its 16v setting which may not be enough when the NUC is working hard. To give an example, my supply is 19v at 3 amps. My NUC is a gen 7 so it’s Turbo mode only kicks in at the very top of its power requirements. I can disable Turbo, keep 90% of the i7 performance but still avoid pushing the PSU beyond its limits.
