Can I attach 6.4A of components to a single PSU 6-pin peripheral (SATA) port?
the PSU has 2 ports, but it'd be easier to run off 1
I'll be making a custom cable. I'd prefer to use 18awg for SFF. Total length between 2-3 feet. 4x connections (2x SSDs, 1x HDD, 1x fan hub)
I'm confused about calculating SSD power draw, but other than that I've spec'ed everything & theoretically it will pull about 6.42A peak
Link to SSD specs. It doesn't list amperage, only Volts & Watts. I used W/V for my calculation:
ex. 3.5W max / 5V = 0.7A
Specs:
Corsair SF450 PSU
10 miscellaneous fans
1 AIO
3' of leds in the future possibly
500gb 850 Evo
1tb 850 Evo, headroom for 2tb in the future
6tb WD60EZRZ
7700k/GTX 1080. Thinking of going AMD+Volta next
Link to PSU
Other thoughts:
If I've got this straight, a 6-pin peripheral cable uses 3x 12v cables, 2 ground cables, and a Sense A cable.
18awg (single) at 12VDC is safe to 13.5A, or 18A without the margin of safety
From a user on tom's Novuake, "SATA power connectors has a total of 15 pins of which 9 are power pins (3 x 3.3V, 3 x 5V, 3 x 12V). Each pin can carry 1.5Amps for a total of 13.5Amps. BUT as there is as yet no use for the 3.3V pins the effective power available to drives is only 9Amps."
The calculated peak on the fan hub is 2.97A
Anecdotal evidence finds people running 10+ HDDs off 1 channel
I think all signs are pointing to safe
