The 300W ATX LPSU converts AC to DC with independent DC outputs (+19V, +12V, +9V (7V-19V adjustable), and +5V USB 3.1 type C). One of these outputs could be used with the HiFi 250W DC-ATX mounted in the H5 chassis converting to the ATX DC voltages for the motherboard and components. The HiFi 250W DC-ATX is a SMPS and has much higher ripple values in mV. The 300W ATX LPSU also converts AC directly to ATX DC (+12V, -12V, +5V, +3.3V, and +5V USB) through the ATX modular outputs. These would be connected to ATX modular inputs on the H5 chassis, and then internally to the motherboard and components. These modular outputs have much lower ripple values in mV.

I don't understand why you are taking a S/PDIF signal from your motherboard pinouts into a sound card which transforms it into a signal over USB, and then converting it back to S/PDIF to send it to your DAC. Why not just send the S/PDIF signal directly to your DAC? Also, isn't AES limited to inches of cable run rather than feet as with S/PDIF?
