Hi. I've ordered two PSUs and M7700 adapter to outfit a music server. Generous sharing by others informs me of the usefulness of seperating 'clean/jitter-sensitive' devices from 'dirty/mechanical' devices and their power demands. While I might not NEED 2 PSUs (wattage wise), I am trying to incorporate this theory of segregation, and I would love some advice on the implimentation. Would this be workable or misguided:
PSU 1 (dirty):
2- 90mm fans
1- 120mm fan (will kick on only if needed)
3- 3T WD green AV hard drives
PSU 2 (clean):
MOBO Asus P8Z77-M pro
1- Crucial 128G M4 SSD
possible power splice into USB hub delivering audio out to DAC (?)
In the parrallel useage laid out previously, the CPU and MOBO power are delivered from different units; is that necessary?
Should the MOBO connection 'cross-integration' previously described be handled the same way?
Sorry I did not see your post last time I logged in.
I will send you the PSU's today.
PSU delivers quite clean power since it has a lot of filtering and was specialty design to have as little interferences as possible.
But the rest of your components are consumer components and a Fan and even the HDD can be actually more cleaner than the motherboard.
The main reason for that is that you have high power DC-DC converter on the main board one is for CPU 12V down to 1.xx Volt then there is the one for RAM also under 2V and probably from 12V line.
Is not necessary to power motherboard and CPU from separate power supply unless you want to use a dedicated video card.
But with your setup a single power supply can deliver easily power to the entire PC.
Not sure what you can power with a separate power supply in order to get a "cleaner" power.
The most important is that the sound card is shilled and has his own filter and some quality sound card have that.
Also not sure if your "music server" is just a server so your music is transmitted by LAN or WLAN to other devices or computer or is more of a media center that will play the music directly whit his own sound card. In first case the "dirty" power supply will have zero influence.
