- Exposed sense wire lacks a premium cover for an ultra clean look
The EZDIY-FAB 12VHPWR 12V-2x6 cable is a 60cm sleeved power cable that connects directly from a compatible ATX 3.1 power supply to a modern GPU. It is designed for builders using RTX 40 and 50 series cards with native 16-pin connectors who want a cleaner alternative to the included adapter.
Its standout feature is stable 600W delivery through true 16AWG tinned copper wire and alloy copper terminals. In real world builds, users report a tight, secure connection with no slack, consistent power under load, and easy routing even in large single chamber cases.
Build quality is a clear strength, with a durable braided sleeve, flexible routing, and five pre-installed cable combs that keep wires aligned and tidy. The 60cm length provides ample reach for most mid and full tower cases while maintaining a streamlined, premium look.
There are a few limitations to consider. It requires a PSU with a native PCIe 5.0 12VHPWR port so it is not universal, and it is not officially supported for RTX 5090 cards. Some users also note the small sense wire is exposed rather than hidden for a fully seamless appearance.
Overall, this is a well built, great value cable for anyone wanting reliable power and cleaner cable management. If your PSU and GPU are compatible, it is an excellent upgrade over the stock adapter for both performance and aesthetics.

How They Compare
Connector Standard and Native Support
The is evaluated as a direct PSU to GPU cable for PCIe 5.1 and 12V-2×6 graphics cards. Per the spec sheet it uses the native 16-pin (12+4) connector and is listed as compatible with RTX 5080, 5070 Ti, 4090, 4080, 4070 Ti and other PCIe 5.0 and PCIe 5.1 cards. It is intended to connect directly from a compatible PCIe 5.0 or ATX 3.1 power supply to the GPU, which reduces the need for a multi-plug adapter.
The is assessed in a completely different category. It provides dual-port USB-C and USB-A wall charging for phones and tablets, with wide compatibility listed for iPhone 14, 13, 12, 11 series, iPad Pro and similar devices. It does not provide a 16-pin GPU connector, it does not interface with an ATX power supply, and it is not rated to power a graphics card. For a deeper look at how case and PSU choices interact, see our Power Supplies category guide.
Power Delivery and Headroom
Power delivery is where the difference is most concrete. The is rated to support up to 600W through true 16AWG tinned copper wire and alloy copper terminals, according to the spec sheet. That rating aligns with the high transient loads of modern high-end GPUs, and the cable is meant to carry the full GPU power over a single run. As with any GPU power setup, you should still follow the graphics card maker recommended wattage and keep headroom above your combined CPU and GPU draw, and you should confirm your ATX 3.1 PSU can sustain that load.
The is not a GPU power delivery device, so it has no 600W rating, no 12V rail, and no PCIe power spec. Owners commonly report efficient charging for small devices and appreciate the intelligent chip that helps guard against overheating and overvoltage for phones, but that protection is for low-voltage USB charging, not for a graphics card. If you need to power an RTX 50 card, this block cannot replace a PSU cable or adapter, and you should plan your PSU wattage around your actual system components instead.
Cable Management and Build Quality
For builders who care about airflow and aesthetics, the is reviewed as a sleeved 60cm cable that includes 5 pre-installed cable combs. The sleeving and combs help you route a single clean run from the PSU to the GPU, which can improve front-to-back airflow and make it easier to maintain proper bend radius near the connector. A single native cable also avoids the extra bulk and potential strain of stacking multiple 8-pin pigtails behind the GPU.
The is evaluated for desk and travel convenience, not internal cable routing. It comes as a compact cube with dual ports in one plug, and the pack includes two units so you can keep one at home and one at work. While that is useful for keeping cables tidy outside the PC, it does not help inside the case. If your priority is internal airflow, you will get more benefit from choosing a case with good GPU clearance, as discussed in how to choose an airflow case for a hot GPU and lian li lancool 216 vs CORSAIR 4000D RS ARGB.
Compatibility and Safety Notes
Compatibility for the depends on having a compatible PCIe 5.0 or ATX 3.1 power supply with a native 16-pin output. The spec sheet notes it is designed for graphics cards using native 12VHPWR or 12V-2×6 connectors, and it includes a clear notice that use with RTX 5090 systems is not officially supported due to extreme power demands. You should verify your exact PSU model is on the cable compatibility list, seat the 16-pin fully until it clicks, avoid sharp bends at the connector, and follow the manufacturer mounting instructions.
The is compatible with a wide range of phones and tablets over USB-C and USB-A, but it is not compatible with GPU power headers and should never be adapted to a graphics card. Its safety features are limited to USB charging protection, and it does not provide the over-current or sense-pin behavior that a proper 12V-2×6 connection requires. If you are building on a tight budget and want to allocate funds wisely, our Budget Build Guides can help you prioritize a quality ATX 3.1 PSU and the correct native cable instead of repurposing unrelated chargers.
Which One Should You Get
Choose the if you have a compatible ATX 3.1 or PCIe 5.0 power supply and a graphics card with a native 16-pin port such as an RTX 5080, 5070 Ti, 4080, or similar. This is the right fit when you want a single-cable run with 600W support, 16AWG construction, and pre-installed combs for a clean build in September 2026. It is especially useful in mid-tower and compact cases where reducing clutter helps with airflow and where you want to avoid the extra joints of an adapter, provided you respect the RTX 5090 limitation and keep PSU headroom above your system draw.
Choose the if your need is outside the PC, for charging phones, tablets, and other USB devices at your desk or while traveling. This is the practical pick when you already have a proper GPU power solution and simply want two compact dual-port cubes for everyday device charging. It is not a substitute for a GPU power cable or adapter, so you should not select it to power an RTX 50 card, and you should keep your GPU power path strictly between a suitable ATX 3.1 PSU and the correct 12V-2×6 cable.
Who Should Skip Both
Both options are not ideal for a builder who needs to power an RTX 5090 or any system where the power supply lacks a native 16-pin ATX 3.1 output and the GPU maker recommends a specific adapter or higher wattage PSU. This is also not a good fit if you are trying to improvise GPU power from unrelated USB chargers or if you need a full ATX 3.1 power supply upgrade rather than just a cable. In those cases, step back and select a PSU that meets the GPU maker recommended wattage with proper headroom, then pair it with the exact cable or adapter that your PSU and GPU documentation specifies.
Frequently Asked Questions
Can I use a USB C charger block instead of a native 12VHPWR cable for an RTX 50 card?
No, a USB C wall charger is not designed to power a graphics card and does not provide a 16-pin 12V-2×6 connection. You need a proper ATX 3.1 power supply and either its native 12V-2×6 cable or the adapter specified by your GPU and PSU makers. Using an unrelated charger for GPU power is not recommended for safety and compatibility reasons.
Is a native 12VHPWR cable better than a multi-plug adapter for RTX 5080 or 5070 Ti?
For compatible ATX 3.1 power supplies, a native single cable like the EZDIY-FAB 12VHPWR PSU Sleeved Cable, 12V-2×6 is often preferred for cleaner routing and fewer connection points. Per the spec sheet it supports up to 600W over 16AWG wire and connects directly from the PSU to the GPU native port. Just confirm your PSU model is supported and follow the GPU maker guidance on wattage and installation.
Does the EZDIY-FAB 12VHPWR cable support RTX 5090?
According to the compatibility and safety notice in the spec sheet, use with RTX 5090 systems is not officially supported due to extreme power demands. If you own or plan to buy an RTX 5090, follow the GPU maker recommended power solution and PSU wattage, and choose a cable or adapter that is explicitly validated for that card and your specific power supply.
