The ARGB runs on its own 5V 3-pin lead, entirely separate from the power path. Leaving that lead unconnected or switching the lighting off in software has no effect on the card being powered. The two functions share a cable but not a circuit.
A glowing head at the end of your card's power connector looks like a feature you can toggle without a second thought, and with the Hydrus 16-pin cable that is exactly right - because the lighting and the power delivery genuinely do not share the same circuit.
This R699 AsiaHorse cable runs its ARGB lighting off a separate 5V 3-pin lead entirely independent of the 16-pin power path. Leaving that lead disconnected, or switching the lighting off in software, has no effect on the card being powered - the two functions share a cable but not a circuit.
It helps to picture this as two entirely separate jobs riding along the same length of sleeving. The 16-pin connection carries the current your graphics card actually needs to run, from the power supply's native socket straight through to the card's power input. The 5V 3-pin lead carries an entirely different, much smaller current specifically for the ARGB lighting inside the head, terminating at a separate addressable header on the motherboard rather than anywhere near the power supply.
Nothing changes on the power side. The card continues to draw exactly the current it needs through the 16-pin connection, completely unaffected by whether the 5V 3-pin lead is connected, disconnected, or simply left dangling. This is a genuinely independent path, not a shared conductor doing double duty.
Whatever addressable lighting control your motherboard software offers applies here in the usual way, since the lighting lead is a standard addressable connection rather than anything proprietary to this cable. Dimming, colour changes, effect patterns - all of that runs through the same software you would use for any other ARGB component on the board.
The physical characteristics of the cable stay exactly the same regardless of whether the lighting is active. The diamond-frosted jacket, the right-angle head shape, the 480W power rating - none of that depends on the lighting circuit being connected or switched on. Buying this cable purely for the finish and the head shape, with no intention of ever using the ARGB, is a perfectly reasonable choice.
Addressable lighting draws a genuinely small current, so unplugging the lead is not really about saving meaningful power - it is almost always an appearance decision, whether that means a cleaner look with the lighting off or simply one less lead to route and secure.
Because a lit head can look convincingly "connected," it is worth remembering that lighting working is not evidence the power connector is fully seated. AsiaHorse's no-gap seating instruction applies to the 16-pin connection specifically, and checking that visually - with the lighting off, if anything, to see the joint clearly - remains the actual test.

No. Power reaches the card through the 16-pin connection, while the lighting draws from a separate 5V 3-pin lead to the motherboard.
Nothing changes. The card is powered exactly as before, since the two paths operate entirely independently of each other.
Yes, through whatever addressable lighting software your motherboard uses, since this is a standard addressable connection.
Yes. The jacket, the head shape and the power rating are all unaffected by whether the lighting circuit is ever connected.
Not really. Addressable lighting draws very little current, so the reason to disconnect it is appearance rather than consumption.
That depends on your motherboard's lighting software settings, in the same way it would for any other addressable lighting component.
No, and that is worth remembering specifically - a lit head confirms only the lighting lead is connected, nothing about the power connection.
