Hi all, first time posting aside from an intro thread I'm jumping into the world of SFF and whilst planning my first build, the thing I'm finding that's the most different from normal sized builds is power delivery. I've not really used anything apart form a regular ATX supply, nor have I customised cables. So I'm after some advice regarding what I can do with my build. Apologies in advance for my dumb replies! STX form factor motherboard Discreet GPU, PCIe powered External power brick + internal PSU I'm using a power brick due to space restrictions, but the issue comes with the PSU choice; From what I can tell an HDPLEX 160W DC-ATX works and gives me a decent range of cables, power for my GPU riser, drive, etc. But because it's an STX motherboard, it will also take power from a DC jack... - So is there a safe way to adapt a cable to go from the HDPLEX to the motherboard DC jack? The Plex would be tucked into a corner, and not be plugged in using it's 24-pin. - I also read somewhere on here about the fluctuating power draw of desktop components, vs the more linear draw like the external brick is designed for, but I can't find the thread. Should I be worried about that? Thanks for reading!
