A right-angle head under a frosted jacket is the part everyone notices first, but the Hydrus 16-pin cable only earns a place in your case once three duller questions are answered: does your power supply have the right socket, does your card sit on the approved list, and is your card one AsiaHorse excludes outright. Get those three right and the finish becomes the fun part. Get one wrong and the lighting never matters, because the cable never goes in.
Quick Answer
Priced at R699 regardless of colour, this modular cable seats into a power supply's native 16-pin socket directly and carries a 480W rating from AsiaHorse. It covers the RTX 40-series plus the RTX 5080 and 5070, but AsiaHorse does not list it for the RTX 5090. Confirm the port and the card first; the ARGB head is the reward for getting the compatibility check right.
Compatibility is the gate, not a suggestion
This is a full modular cable, not an extension you slot behind an existing lead. That means it has to connect at the supply end into a socket that is actually there - a native 16-pin 12VHPWR port, not an adapter bolted onto an eight-pin pair. No socket, no cable, regardless of how much you like the way it photographs.
On the card side, AsiaHorse names the RTX 40-series together with the RTX 5080 and RTX 5070 as the covered range. The RTX 5090 sits outside that list and is explicitly not compatible with this cable, even though it uses the same connector family. A shared plug shape is not the same thing as a listed pairing.
What 480W actually describes
AsiaHorse rates this cable at 480W. That number belongs to the cable alone - it is not a claim about what your power supply can output overall, and it is not your card's power draw either. Those three figures come from three different places (the cable maker, the supply maker, the card maker), and a sensible check compares your card's published draw against the cable's rating rather than assuming one number stands in for all of them.
One pairing AsiaHorse says to avoid
There is a specific caution attached to this cable: two brands, Lian Li and Sharkoon, show up in AsiaHorse's damage reports for this pairing, and a different cable is recommended for either. It is not a blanket warning against the cable itself, just against that particular combination. If your supply is one of those two brands, the cable that came in the box with it remains the safer choice.
Seating and the lighting that shares the connector
Once the cable is through the compatibility check, install care still matters. AsiaHorse asks that the connector be seated fully until it sits firm with no gap before the system is powered on. The comprehensive cable solutions range covers this and its sibling extensions if you want to compare options before deciding. The lighting head runs off a separate 5V 3-pin sync lead, so it is a cosmetic layer on top of a power connection that has to be right on its own. For the card side, browse graphics card accessories to see what else pairs with a 12VHPWR-equipped build.
Frequently Asked Questions
What has to be true before this cable fits?
Your power supply needs a native 16-pin 12VHPWR socket, and your card has to be one AsiaHorse names - which rules out the RTX 5090 specifically.
What does the 480W figure actually cover?
It is AsiaHorse's rating for the cable itself, not a statement about your supply's total output or your card's draw.
Which cards are on the compatible list?
12VHPWR cards spanning the RTX 40-series plus the RTX 5080 and 5070. The RTX 5090 is named as excluded.
Is this the same as the ATX or EPS extension cables?
No. Those extend an existing lead; this one plugs straight into the supply and replaces the factory cable at that socket.
Are there power supplies to be careful with?
AsiaHorse flags elevated damage reports on Lian Li and Sharkoon units paired with this cable, and suggests keeping a different cable for those.
What colours does it come in?
Black and white, identical spec and price at R699, both with the right-angle Type A head and 50cm reach.
When can I actually buy one?
The listing is hidden until trial stock lands; no arrival date has been confirmed, so treat it as coming rather than available today.
