Installing a GPU

Riser Cable Requirement

The DA6 is a sandwich layout design which means a riser card is required. We do NOT include a cable with the case for a number of reasons such as the different PCI Gens (V3, V4, V5) and because some customers may already have a usable riser cable. We do however offer a compatible rider cable either sold separately or as part of a bundle with the case.

Should you wish you use your own cable, it needs to be a double 90 angle type with a length of 20-22cm, as shown in the example below.

Riser Cable Placement

The DA6 features the ability to move the GPU position allowing for different width cards to be centered. Moving the GPU means the riser cable will also need to allow for this adjustment so a slightly longer cable is preferable to allow for this movement.

One way to allow for the additional cable slack is the routing of the cable. It can be passed either in front of the motherboard post or behind it depending on the GPU position and of course your preference for look.

PCIe Card Lock Clip Removal (for RZ21B)

When using the RZ21B riser cable, depending on mounting, the lock clip will conflict with the riser bracket. This is a known issue and related to the difference in clip design from the originally planned riser cable.

The recommended fix is to simply remove the clip as it is not required to lock the card when used with the DA6 and will not impact the usability in any way.

Please take care when removing the clip so that it can be reused in future if needed.

Fitting the Riser Cable

The riser cables secures to the DA6 via 2 brackets on the motherboard post.  The DA6 will come with the brackets already assembled.

Remove the screws with plastic washer and use them to secure the riser cable to the bracket ensuring the washer is spacing the PCB away from the brackets.

The riser cable does NOT need to be fitted prior to installing the card and can be fitted to the card first. This might be useful when fitting large cards.

GPU 'X' Position Adjustment

The position of the GPU can be adjusted via the riser cable brackets (show above) and the PCI upper/lower mounts.

The PCI upper/lower mounts are attached to the bottom panel via 4 screws. Loosen these to adjust their position. The spacing between these mounts must be kept the same to ensure correct spacing for the GPU fitting. This is easy to achieve by using the connecting side as a spacer. When correctly adjusted, this will form a good fit between the upper and lower mount.

There is 15mm of adjustment available, smaller card will be biased towards the center (position A), larger cards based towards the edge (position B)
The position can be adjusted anywhere between A and B, its not limited to just either.

GPU 'Y' Position Adjustment

The DA6 can support cards with up to a ‘3 slot’ bracket, but the card itself can be more than 3 slots thick. By default all cards are installed in slot 1, the position closest to the motherboard, however, for cards with a 1 or 2 slot bracket, the position can be adjusted.

Unlike a conventional case, the DA6 features a ‘clamp’ mechanism, allowing the card to be ‘locked’ anywhere along the mount using the screws at either side. There are additional fixing points along the upper mount for added security, these are spaced according to the standard PCIe bracket spacing.

Upper Mount

The default position (slot 1) is actually defined by the riser cable which is fixed to the motherboard post (via the adjustable brackets). Having the riser cable fixed to the post means that cards are secured by the PCI bracket and the PCIe slot, ensuring that large/heavy cards are well supported. For smaller cards or in builds where the system wont be subject to any movement, the riser cable can be detached from the bracket to allow the GPU to be spaced away from the motherboard. This can be useful for better cooling or to make space for hardware placement.

You dont need to fully remove the screw used to secure the upper mount lock bar, just loosen them.

Typical installation with the card being located in ‘slot 1’ and with the riser cable secured to the motherboard post

With the riser cable detached from the brackets, the card can be spaced away from the motherboard. In this example the card is only slightly spaced away from the motherboard, but in principle it can be moved anywhere along the PCI mount.

We include extended spacers and screws to allow slot 2 to be used while retaining the added security of the riser card being fixed to the motherboard post. Simply use the extended spacers to secure the riser cable to the brackets.

In this configuration, the card is now located in what would typically be called ‘slot 2’ and secured with the mount and riser, giving the same security as the default location. This is idea for spacing large/heavy 2 slot cards away from the motherboard.

Cards with a single slot bracket can be fitted in what would be called ‘slot 3’ (or anywhere along the mount) but wont be secured by the motherboard post

GPU Installation

With all of the above out of the way, the installation process is relatively straight forward, the steps are shown below. We recommend loosening all the screws so the PCI and Riser mounts position can be adjusted during the installation.

Loosen the two screws that secure the lock bar, they are accessible though the gaps between the PSU pass-though socket as seen from this angle.

Position the GPU into the case ensuring the lower edge of the card bracket slots into the lower mount and the upper edge fits between the upper mounts.

Lock the GPU to the case by tightening the upper mount screws.

Plug into the riser cable and adjust the position of the GPU so that it is centered. Lock the position by tightening all screws.
