A case that lets its power supply cage come out entirely changes how you should approach fitting a Hydrus 16-pin cable - not because the cable itself behaves differently, but because the order you do things in suddenly has real consequences for how much rework you end up doing.

Quick Answer

In a case with a removable power supply cage, route and connect the R699 AsiaHorse Hydrus 16-pin (12VHPWR) cable's supply end while the cage is still out, confirm the fit works, and only then refit the cage. Both ends of this cable need reaching during the install, and its 50cm run leaves little slack - the wrong order generally means taking the cage back out to fix something.

What a removable cage actually offers

Being able to pull the power supply and its associated cabling entirely out of the case removes the single biggest obstacle to a clean install: working blind inside an enclosed basement chamber. With the cage out, the modular panel is fully visible and fully reachable, which makes confirming a proper seat at the supply end considerably easier than it would be with everything already boxed in.

Connecting the supply end first

With the cage still separate from the case, connect the cable to the supply's native 16-pin socket and confirm it is fully seated - flush, no gap, no movement under light pressure. This is the easiest point in the entire install to do that check properly, since there is nothing else in the way and the whole panel is in plain view.

Positioning the cage before fixing it down

Once the supply end is connected, position the cage roughly where it will sit permanently, and route the cable's remaining length toward where the card will be, without committing to anything final yet. This is the stage to catch a route that turns out to be too tight, or a length that comes up short, while the cage is still easy to reposition.

Where the card end fits into the sequence

The card end generally comes second, once the cage is in something close to its final position and the card itself is installed or about to be. That end stays reachable from the case's open side throughout the rest of the build, which is a more forgiving connection to leave for later in the process than the supply end, which becomes harder to reach the moment the cage goes back in fully.

Why 50cm leaves so little room for error

Because this is a direct replacement cable rather than an extension, its 50cm length is the entire distance available between the supply socket and the card - there is essentially no slack to draw on if the route ends up longer than expected. That makes getting the sequence right considerably more important than it would be for a cable with room to spare; a route that comes up short after the cage is fixed down is a genuinely more frustrating problem to solve than one caught while everything is still loose.

When it is safe to commit the cage permanently

Only once both connectors are confirmed fully seated, the reach has proven adequate along the actual route, and the right-angle head at the card end clears whatever panel or component sits near it should the cage screws actually go in. Committing earlier than that is what creates the need to remove the cage a second time.

If your case's cage position is adjustable

Some cases allow the cage itself to sit at more than one height or depth. Where that is true, cage position becomes one more variable in the route planning - worth deciding early, since it directly affects how much distance the cable actually has to cover.

Frequently Asked Questions

What is the advantage of a case with a removable power supply cage?

It lets the supply and its cables be worked on entirely outside the case, far easier than reaching into an enclosed basement chamber blind.

When should the cable be connected at the supply end?

While the cage is still out, so that end can be seated and confirmed with the whole panel fully visible and reachable.

Does the card end come first or second in the sequence?

Usually second, once the cage is roughly positioned, since the card end stays reachable from the open side throughout the rest of the build.

How does the cable's 50cm length affect the installation order?

It leaves very little slack, so getting the sequence right matters more here than it would for a cable with room to spare.

What if my case's power supply cage position is itself adjustable?

Then cage position becomes part of route planning, since moving it changes how much distance the cable actually has to cover.

Should the cage screws go in before or after confirming the fit?

After. Fixing the cage down before the route and both connections are confirmed is what creates the need for rework.

Is the seating check still possible once the cage is fully back in place?

At the card end, generally yes. The supply end becomes harder to see, which is why confirming it before refitting matters most.
