New here + reasonably new to electronics - can solder + hack, but anything finer I need help with!
Building a games rig out of an old console case. I'm looking to have the PSU outside of the unit to keep temps low.
The key component is an Odroid XU4 (http://www.hardkernel.com/main/products/prdt_info.php?g_code=G143452239825) It's rated at 5V/4A. I've been advised that the voltage/A needs to be super steady:
"5Volt +/-5% tolerance is required. So the PSU must have well regulated output at 4.75V ~ 5.25V range."
What I'm seeking to do is also power other components in the unit. Thankfully all at the same voltage:
Powered USB2 Hub - 5V 3A Powered USB3 Hub - 5V 1A HDMI Audio splitter - 5V 1A
Thus, I'll need a new PSU (I'm guessing rated at 5V 9A??). My questions are:
1) How do I split the 5V supply 'cleanly' in the unit - that is to make sure the Odroid is protected. I've been advised against something like this, due to 'voltage drops' or something:
2) Considerations around buying the 5V 9A PSU? Need anything in particular?
Been re/searching for a couple of days now and still none the wiser. Thanks + hope someone can help!
EDIT: Worried my potential solution got lost in the comments below. So put here.
So will this work:
I can amend my design to use: 1x12Vx2.5A USB3 Hub; 1x5Vx1A HDMI splitter and the Odroid @ 5Vx4A.
I see a 120W picoPSU with ratings: 5V @ 6A, 5VSB @ 1.5A, 3.3V @ 6A, 12V @ 7A, -12V @ 0.05A. So this should work, right? One question though, I'd have to put the Odroid on the 6A 5V line, but would need the 5VSB line activated to power on the other devices?
