D5 NEXT Pump and USB Header Questions

Thursday, July 4th 2024, 4:18am

Hi everyone, I'm completely new to watercooling and I'm figuring out how to connect my D5 NEXT pump to power. I know that the manual says to use SATA power, but the pins on the inside don't look like they match with my PSU's SATA cable. There are four pins on the D5 NEXT, but the PSU cable has an L-shaped hole with many pin holes on the inside. Do I need to just use that cable anyways, or is there some sort of adapter that I need to use?

I'm also a little confused about the USB headers on the Aquacomputer devices and how they connect to my motherboard. I have an Ultitube + D5 NEXT + Leakshield combo, along with a QUADRO and a High Flow NEXT. Each of those has its own USB cable that should plug into my mobo (Gigabyte X670e Aorus Pro X). The mobo has two USB 2.0/1.1 ports, but those ports do not have the same amount of pins as the USB cables from the devices. The devices each have 5 pins and the ports have 9 pins each. I know that I'll need to get a HUBBY7 to accomodate the number of cables I have, but I just want to check how the cables should be oriented within the USB 2.0/1.1 socket. This is my first time watercooling and building a PC in general, so I apologize if these are noob questions. Thanks in advance!

You are refering to the "Fan" output (4 Pins) - the L-shaped Power Connector is above (following Picture is upside down):


Every 2.0 Header on the Motherboard consist of two USB-Ports, therefore you can connect four Aqua Computer Devices to your two USB 2.0 Header on your Motherboard.
Take a look at Page 7 of the manual.

In the above Picture is space for one more Device :-)

Most important thing: The side with the missing pin always indicates the direction for the connector (also true for HUBBY7). The black ground cables must be located there.

Thank you both! I've hooked everything up now!

Good that you got everything connected. You still may want to consider getting a Hubby7. Its a very well designed, reliable USB2.0 internal hub. The Hubby7 can be powered by SATA or USB which is a nice feature. You can plug some or all of the Aquacomputer devices into the Hubby7 so 3 of the Mobo USB2.0 ports are available for other devices. Also, the Leakshield is powered by USB. If you want to maintain negative pressure for leak protection even when the computer is off, you need to plug its USB cable into a USB port that stays powered. You may have to configure this in the BIOS of the motherboard.

If the USB port is to be used for power with system off (leakshield), do not use the external SATA power from the PSU.

I currently have all four of my devices plugged into my motherboard, and the D5 NEXT has its SATA port connected to the PSU. I don't think the Leakshield draws power from that SATA port, right? If that's the case, then I should just need to adjust the BIOS settings like Speedy-VI mentioned.

My comment was just for the splitty7, if you use the sata input from the psu, you will not have power to the usb ports with system off

The Leakshield (LKS) is powered by its USB port. It has nothing to do with the SATA power connection to the D5 Next. If you decide to get a Hubby7, I would power it with SATA but plug the LKS USB cable directly into one of your mobo USB2.0 headers, which you should be able to configure in the BIOS to remain powered when the computer is shut down. This way the Hubby7 can deliver 1000ma max to whatever is plugged into it and the LKS gets its power directly from the mobo USB2.0 header that remains powered when the computer is shut down. The Hubby7 manual says when SATA powered, it can provide 500ma total for ports 1, 2, and 3 (combined) and 500ma for ports 4, 5, 6, and 7 (combined). Keep that in mind when you decide which ports to plug things into. The LKS can pull up to 500ma which is the max a typical USB2.0 port can provide. IMHO, it's best to power the LKS directly from the mobo.

If you set a mobo USB2.0 port to remain powered, plug the Hubby7 into that USB header, set the switch to USB power, and then plug the LKS into a port on the Hubby7, it will pull the total amount of current that the USB port and the Hubby7 can deliver when powered by USB. You could not use any of the other ports on the Hubby7 which defeats its purpose. If you powered the Hubby7 with SATA and plugged the LKS into Hubby7 USB port 1, you could not use ports 2 and 3. If you plugged the LKS into Hubby7 USB port 4, you could not use ports 5, 6, and 7. And the LKS will lose power when the computer is shutdown. It just makes more sense to power the LKS directly from the mobo, and power the Hubby7 with SATA power so you can have the full 1000ma available to the devices plugged into it.
