AI Verdict
This 300mm sleeved extension cable replaces the ugly stock Nvidia adapter for RTX 3060 Ti, 3070, and 3080 Founders Edition cards, giving your build a cleaner look.
It does exactly what it claims for RTX 3060 Ti, 3070, and 3080 Founders Edition cards by hiding the ugly stock adapter. Because it is an extension rather than a direct-to-PSU cable, it adds 300mm of bulk that you have to hide in the back of your case.
If you have an RTX 3080 Ti or 3090, you must buy the 16AWG version of this cable to handle the higher power draw safely.

Chance this product isn't for you
Pros
- Replaces the bulky stock Nvidia dongle with a clean, single sleeved run to the GPU
- Includes three pre-installed cable combs to keep the individual wires perfectly parallel
- 300mm length gives you plenty of slack to hide the 8-pin connection points behind the motherboard tray
- Uses standard UL1007 18AWG wire which easily handles the 320W power draw of an RTX 3080
Cons
- Only 6 of the 12 pins are actually populated with metal contacts, which looks alarming out of the box
- The outer sleeving has a stiff, waxy feel that makes tight bends near the glass side panel difficult
- It is an extension, not a replacement cable, so you still have to cable-manage your PSU's original 8-pin cables in the back
Dimension Scores
This is a power cable that delivers stable voltage to the GPU, meaning it has zero impact on actual framerates.
Replacing the bulky stock adapter with a single sleeved run slightly improves the airflow path from your front intake fans.
The 18AWG UL1007 wire safely handles the 320W load of an RTX 3080, but lacks the thickness required for a 3090.
This is a physical power extension cable and does not interact with or affect the graphics card's memory.
Best For
- RTX 3060 Ti, 3070, or 3080 Founders Edition owners who want to fix the ugly stock power adapter
- PC builders who want the custom sleeved look without buying a full replacement cable kit
Not Recommended For
- RTX 3080 Ti or 3090 owners — this uses 18AWG wire, and those cards require thicker 16AWG wire to prevent melting
- Small form factor (ITX) builds where hiding an extra 300mm of cable and two 8-pin connectors is impossible
- Anyone with an RTX 4000 series card, which uses the newer 16-pin 12VHPWR connector
Watch Out For
- Only half the pins have metal contacts inside the 12-pin connector. It works perfectly fine for the 3080, but it looks like a manufacturing defect if you don't know to expect it.
- This is an extension cable, meaning it plugs into your existing PCIe cables. You need extra space in your PSU shroud to hide the bulky connection joints.
- The stiff sleeving requires a wide bend radius. If your GPU sits right up against your case's glass side panel, this cable will push against the glass.

What Buyers Say
Looking inside the 12-pin connector and seeing that half the metal pins are missing causes immediate panic for many. Once you realize this is by design for the 3080's power delivery, the panic subsides and the aesthetic upgrade shines. The stiff, waxy sleeving holds its shape perfectly thanks to the three included cable combs. The main frustration is cable management, as hiding the bulky plastic joints where this extension meets the original PSU cables takes some serious shoving in the back of the case.
“Thought mine was broken because half the pins are empty inside the connector, but it works perfectly and looks a million times better than that hideous Nvidia adapter.”
Common Praise
- Massive visual upgrade over the short Nvidia stock dongle
- The three included cable combs keep the wires perfectly aligned and parallel
- The stiff sleeving holds its trained shape well once you bend it into place
- Snaps securely into the GPU with a reassuring click
Common Complaints
- The 12-pin connector only has 6 metal contacts inside, which causes initial panic
- The stiff wires make it hard to close the glass side panel in narrower cases
- Adds a lot of extra cable bulk to hide in the PSU shroud
- The white sleeving has a slightly glossy, waxy finish rather than a matte fabric look
Ownership Tips
- The cable combs can be tough to slide up and down the stiff sleeving without fraying the material
- You have to pre-bend the cable before plugging it into the GPU to avoid putting stress on the connector
- Dust wipes off the waxy sleeving much easier than it does on paracord cables
Frequently Asked Questions
Does this plug directly into my power supply?
No, this is an extension cable. You plug your power supply's existing 8-pin PCIe cables into this, and then plug this into the graphics card.
Why are there empty pins inside the 12-pin connector?
Only 6 pins are populated with metal conductors because the dual 8-pin configuration only requires those specific pins to deliver power to a 3080. It is completely normal and safe.
Will this work with my RTX 4080 or 4090?
No. The RTX 4000 series uses a different 16-pin 12VHPWR connector. This 12-pin cable will not fit.
Can I use this with an RTX 3090 Founders Edition?
The manufacturer explicitly advises against it. The 3090 draws too much power for these 18AWG wires; you need a 16AWG cable instead.
Does this work with partner cards from Asus, MSI, or Gigabyte?
No. This 12-pin connector is exclusive to Nvidia's Founders Edition cards for the RTX 3000 series. Partner cards use standard 8-pin connectors.
Buying Guide
You are buying an aesthetic upgrade, not a performance part. This cable exists purely to get rid of the ugly black adapter Nvidia included in the box. Because it is an extension, you need to make sure you have enough empty space in your case's basement to hide the extra 300mm of wiring and the bulky plastic connectors. Check your exact GPU model before buying — this only fits Founders Edition cards, not the ones made by Asus, MSI, or Gigabyte.
18AWG Wire Gauge
AWG measures the thickness of the copper wire. 18AWG is standard and perfectly safe for a 3080, but thicker 16AWG wire is required for power-hungry monsters like the 3090.
300mm Length
This is about one foot of cable. It is long enough to reach from your GPU, through the rubber grommet, and into the back of your case where you can hide the ugly connection to your main power supply cables.
12-Pin Connector
This is Nvidia's proprietary plug used only on RTX 3000 series Founders Edition cards. It is completely different from the 16-pin plug used on the newer 4000 series.
Alternatives
If you have an RTX 3090 or 3080 Ti, search for a '16AWG 12-pin extension' to handle the extra power. If you want to avoid hiding extra cable bulk, search for a 'direct replacement 12-pin cable' specifically made for your exact power supply brand.
