Get your ATTACK SHARK X820 ULTRA and C01ULTRA coiled cable connected in minutes. Follow these ordered steps for a clean, reliable first setup.
Quick answer
Connect the C01ULTRA coiled cable to the X820 ULTRA's USB-C port first, then plug the other end into your computer and choose your preferred connection mode. Keep the coiled section relaxed and supported so the cable never pulls on the keyboard.
Why the order of connection matters
Plugging the cable into the keyboard before the computer gives the X820 ULTRA a stable power and data path from the start. If you connect the computer end first, the keyboard may briefly enter a charging or pairing state before the cable is fully seated, which can cause a missed keystroke or a failed first pairing.
The C01ULTRA coiled cable is designed to absorb strain. That only works if the coil has room to flex. Route it with a gentle arc rather than a tight bend at the connector.
When wired is the better choice
The X820 ULTRA supports three connection modes, so you are not locked into wired use. Choose the cable when you want the lowest possible input delay, when you are setting up for the first time, or when the keyboard's battery needs charging. For travel or couch use, the wireless modes are more convenient, but the C01ULTRA cable still works as a charging cable.
If your desk has limited space behind the keyboard, a coiled cable can actually save room because the coil compresses. Just avoid routing it under a heavy monitor stand or sharp desk edge.
X820 ULTRA and C01ULTRA setup steps
- Place the keyboard and plan the cable path: Set the X820 ULTRA where you want it, then lay the C01ULTRA cable loosely from the keyboard's USB-C port toward your computer. Leave the coiled section relaxed, not stretched. Common mistake: pulling the coil tight against the connector, which puts strain on the port. Check that the cable can move a few centimeters in every direction before you connect anything.
- Connect the cable to the keyboard first: Plug the C01ULTRA cable into the X820 ULTRA's USB-C port until it seats fully. Do not force it; the connector is keyed. Common mistake: plugging into the computer first and then fumbling under the keyboard, which can bend the connector. A fully seated cable should not wiggle when you gently tug the connector housing.
- Plug the other end into your computer: Connect the USB-A or USB-C end (whichever your C01ULTRA cable uses) to a free port on your computer. Prefer a rear motherboard port over a front-panel hub for the most stable connection. Common mistake: using an unpowered USB hub, which can cause the keyboard to disconnect intermittently. If the keyboard is not recognized, try a different port before assuming the cable is faulty.
- Select wired mode on the X820 ULTRA: Use the keyboard's connection mode switch or shortcut to select wired (USB) mode. The exact control is described in the X820 ULTRA manual. Common mistake: leaving the keyboard in Bluetooth or 2.4 GHz mode while expecting wired behavior. Confirm the mode indicator matches wired mode before you start typing.
- Test every key and check cable slack: Open a text editor and type a sentence that uses letters, numbers, and punctuation. Then gently push the keyboard forward and back to confirm the coiled cable compresses without pulling the connector. Common mistake: skipping the slack test and later yanking the cable during a game. Adjust the cable's position until the coil absorbs movement, not the connector.
- Route the cable for daily use: Use a cable clip or the gap under your desk to keep the C01ULTRA cable out of your mouse path. Keep the coil visible and supported rather than hidden under a heavy object. Common mistake: routing the cable over a sharp desk edge or under a chair leg. Recheck the routing after a week; cables often settle and shift.
