D5 Next Specifications

Tuesday, February 11th 2020, 3:43am

Hi,

How much current does D5 NEXT consume:
5V = ?A
12V = ?A

I need to know this because I'm building a non-PC water cooling rig for non-computer application and I need to select the right power supply (cannot use a computer power supply, it's too big and bulky and I don't need it for anything else).
I could not find this information in the manual, manual only states the rail voltage and combined power consumption 65W.

Thanks

A D5 pump needs 25-30 Watts on 12V.
The electronic module needs <5 Watts on 5V.

The connected Fans can use up to 25 Watts on 12V
The connected LEDs uses some Power on 5V.

This is a total of 65 Watt of combined Power consumption.


And a Warning:
The USB Power rail and the SATA Power connector are not seperated!
If you use an external power supply for the pump, and connect the pump with USB to a Computer, it can damage the Computer and/or the Pump!

Hufeisen thank you, good point about the USB power, computer and power supply could have different potential grounds thus resulting in overvoltage condition.

Looks like to be safe, a power supply should be:
12V @ 5A max = 60W max (25W for fans, 25W for pump, 10W overhead safety for PSU)
5V @ 1.5A max = 7.5W max (5W for electronics and LEDs, 2.5W PSU overhead)

Quoted from "kandrey89"

12V @ 5A max = 60W max (25W for fans, 25W for pump, 10W overhead safety for PSU)
5V @ 1.5A max = 7.5W max (5W for electronics and LEDs, 2.5W PSU overhead)
When you use a industrial psu (Meanwell, TDK,.. ) this is OK.
But when you use any of the chinese PSU models, plan 100% as headroom.
