This fasgear pcie 5 1 power cable review covers a 70cm adapter designed for high-end graphics cards. It converts two 8-pin (6+2) connectors into a single 12VHPWR (12+4) plug. The cable uses 16AWG tinned copper wires to support up to 600W of power output. This gauge is thicker than the standard 18AWG, offering more stable voltage transmission. It is specifically engineered for full modular power supplies from ASUS, EVGA, or Seasonic. The length helps keep your build tidy compared to shorter original cables. You need three unoccupied 8-pin ports on your PSU for this to work correctly.
What stands out
- 16AWG tinned copper wire construction for stable power delivery
- Supports up to 600W output for RTX 4090 and 4080 cards
- 70cm length with included transparent cable combs for neat management
- Specifically compatible with ASUS, EVGA, and Seasonic modular PSUs
Who it fits
Good fit for
You should buy this if you own a full modular PSU from ASUS, EVGA, or Seasonic. It is ideal for users with RTX 4070 Ti, 4070, 3090 Ti, 4080, or 4090 graphics cards that use a 12+4 pin female connector. You need a PSU with enough 8-pin ports to spare, as three must remain unoccupied. This cable helps you achieve a cleaner look in your PC case by replacing short, awkward original cables with a longer, sleeved option that includes management clips.
Who should skip it
Skip this product if your power supply is not fully modular. It will not work with semi-modular or non-modular units. You must also ensure your PSU is from ASUS, EVVA, or Seasonic. It is incompatible with Corsair, Great Wall, Thermal Take, or NZXT models, which have different variations. Do not use this if your GPU uses an 8-pin or 12-pin connector instead of the 12VHPWR standard. Connecting fewer than three 8-pin connectors to the PSU may cause system damage.
Verdict: This cable is a solid choice for owners of specific modular PSUs upgrading to RTX 40-series cards. It provides the necessary power handling and length for a tidy build, provided your hardware matches its strict compatibility requirements.
Key specs explained for this cable
Length: 70cm
This cable measures 70cm, which is significantly longer than the standard 10cm cables that often come with power supplies. You will find this extra length helpful for reaching graphics cards in larger cases. It allows you to route the cable more cleanly without straining the connectors. This length helps you keep your build tidy and makes installation easier in tight spaces.
Wire Gauge: 16AWG
The cable uses 16AWG tinned copper wires instead of the standard 18AWG. This thicker gauge reduces electrical resistance, which helps maintain stable voltage under heavy loads. You benefit from safer power delivery when running high-end graphics cards. The tinned copper also resists oxidation, which helps the cable last longer. This is a key spec for anyone building a high-performance PC.
Max Output: 600W
This adapter supports up to 600W of power output. This rating is suitable for demanding graphics cards like the RTX 4090 or 4080. You need to ensure your power supply provides enough total wattage to handle this load. This spec tells you the maximum power the cable can safely carry. It is essential for users planning to install high-end GPUs in their systems.
Compatible PSU Brands: ASUS, EVGA, Seasonic
This cable is designed to work only with fully modular power supplies from ASUS, EVGA, or Seasonic. You must check your power supply model before buying. It will not fit semi-modular or non-modular units. This restriction limits which systems can use this cable. You should verify your existing power supply is one of these brands to ensure proper connectivity and safety.
Connector Type: 16-pin to 2x8-pin
The cable converts two 8-pin (6+2) connectors from your power supply into a single 16-pin 12VHPWR plug. You need three unoccupied 8-pin ports on your PSU for this to work safely. This adapter is for graphics cards with a 12+4 pin female connector. It is not compatible with 8-pin or 12-pin GPU connectors. This design simplifies cable management for modern high-end cards.
Design and build quality
The listing specifies that this cable is constructed from 16AWG tinned copper wires. This gauge is thicker than the standard 18AWG, which allows for stable voltage transmission and supports up to 600W of output. The tinned finish helps prevent oxidation over time. The plug terminals use alloy copper and tinned material to ensure reliable connections. You get four transparent acrylic cable comb clips to help manage the sleeved cord. This setup keeps your build neat and tidy compared to using multiple loose cables. The cable itself is black, matching common interior aesthetics. It measures 70cm, or roughly 2.3 feet. This length is much longer than the original 10cm cables that often ship with power supplies. The extra reach helps you route power cleanly in larger cases. The packaging dimensions are listed as 4.72 by 4.53 by 1.38 inches. The total weight is 6.35 ounces. This lightweight design makes handling easy during installation. You must ensure your power supply is fully modular and compatible with ASUS, EVGA, or Seasonic models. The cable requires three unoccupied 8-pin ports on your PSU to function properly. Connecting fewer connectors may cause system damage. It only supports GPUs with a 12+4 pin female connector, such as the RTX 4070 Ti or 4090.
Setup And Daily Use Guide
Setting up this cable requires careful attention to your power supply model and available ports. The listing specifies that it is only compatible with fully modular power supplies from ASUS, EVGA, or Seasonic. It will not work with semi-modular or non-modular units. You must ensure your power supply has at least three unoccupied 8-pin (6+2) PCIe ports. Connecting fewer than three connectors can cause system damage. This adapter converts those three ports into a single 16-pin 12VHPWR connector. You need to verify that your power supply output wattage is sufficient for high-end graphics cards like the RTX 4090 or 4080.
Daily use involves connecting the 12VHPWR end to your graphics card. The cable supports GeForce RTX 4070 Ti, 4070, 3090 Ti, 4080, and 4090 models. It is not compatible with GPUs that use 12-pin or 8-pin connectors, such as the standard RTX 4070 or RTX 3090. You must ensure your GPU has a 12+4 pin female connector. The 70cm length helps keep your build tidy by reducing cable slack. The included acrylic cable combs allow you to manage the sleeved cord neatly. The 16AWG tinned copper wires provide stable voltage transmission. This thickness reduces resistance compared to standard 18AWG cables. The tinned finish also helps prevent oxidation over time. You simply plug the cables into the PSU and GPU. The setup is straightforward if your hardware matches the specified requirements. This cable serves as a replacement for shorter original cables, improving cable management in your case.
Before you buy this cable
You need to verify your power supply is fully modular and matches one of the supported brands: ASUS, EVGA, or Seasonic. This adapter will not work with semi-modular or non-modular units. You must also confirm your PSU has at least three unoccupied 8-pin (6+2) PCIe ports. Connecting fewer than three connectors can damage your system. Ensure your GPU uses the 12+4 pin female connector, as it is incompatible with 8-pin or 12-pin connectors found on older cards like the RTX 3090. The 70cm length helps with cable management in larger cases, keeping your build tidy with the included acrylic clips. This cable serves as a direct replacement for shorter original cables, offering better reach and stable power delivery for high-end GPUs. It fits well into builds where original cables are too short or cluttered. Always check your PSU wattage is sufficient for your graphics card before installation.
Check before you buy
- Confirm your PSU is fully modular from ASUS, EVGA, or Seasonic
- Check for at least three unoccupied 8-pin PCIe ports on your PSU
- Ensure your GPU uses a 12+4 pin female connector
- Verify your PSU wattage supports your graphics card power needs
