Do not heat up like cheapos I got elsewhere - I have some HP Z-series workstations. These have beefy 1150W power supplies, but only three 6 pin power cables (no 8-pin). The 6 pin cables run over 150W per cable, though, unlike most system (in other words, they are way more powerful than the nominal spec). Anyway, modern video cards all require 6+8 or 2x8 power adapters. What to do? Well, the easy thing is to use a 6-> 8 pin adapter. Since the power supply on the HP is sending well over the 8-pin spec along that rail, it's no problem. I first tried some budget cables I got off an auction site. They look great, and the wire casings are nice and thick, but as soon as I put stress on the video card, they got VERY hot. Cutting one open reveals very thin wire. No good. So I got these Cable Matters cables. They actually aren't much more expensive than the cables they are replacing. And these work GREAT. The cables do not heat up at all, even under full stress load. Nice. I will only use these cables from now on. Review: Great - Used them to connect my RTX 3070 gpu to my Dell 5810 tower. Worked perfectly ## Features - 6 Pin to 8 Pin PCIe Adapter: Connect a 6-pin male PCIe power plug from a compatible power supply to the 8-pin PCIe power input on a supported graphics card. Confirm the connector types before ordering - For Compatible Low-Power GPUs: Use the PCIe power adapter only when the power supply and its 6-pin PCIe connection provide sufficient power for the graphics card. Check the documented power requirements of the PSU and GPU before installation - 8 Pin to 6 Pin PCIe Adapter: The GPU power adapter changes a 6-pin PCIe connection into an 8-pin connector but does not increase the PSU wattage, current capacity, or available power. It is not suitable for bypassing GPU power requirements - Secure PCIe Connections: The 8-pin male connector features a locking latch, while the 6-pin female connector uses a keyed housing to support proper alignment and help prevent accidental disconnection - Convenient 2-Pack: Use the two PCIe adapter cables with separate compatible systems or keep one as a spare. Compatible with select Gigabyte, Radeon, and Sapphire graphics cards with an 8-pin PCIe power input. Check the GPU power requirements before use. Not compatible with CPU/EPS 8-pin ports ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B01DV1Z32Y | | Best Sellers Rank | #15,876 in Electronics ( See Top 100 in Electronics ) #226 in Audio & Video Power Cables | | Brand | Cable Matters | | Brand Name | Cable Matters | | Cable Type | proprietary | | Color | Black | | Compatible Devices | Computer | | Connector Gender | Male | | Connector Type | 6-pin Pcie, 8-pin Pcie | | Customer Package Type | Standard Packaging | | Customer Reviews | 4.7 out of 5 stars 3,227 Reviews | | Ethernet Cable Category | Cat 5 | | External Testing Certification | Não aplicável | | Gauge | 18 | | Indoor Outdoor Usage | Indoor, Outdoor | | Item Length | 4 inches | | Item Shape | Round | | Manufacturer | Cable Matters | | Maximum Voltage | 50 volts_of_direct_current | | Model | 104042x2 | | Number of Pins | 14 | | Other Special Features of the Product | Secure Connection | | Part Number | 104042x2 | | Recommended Uses For Product | Powering Graphics Cards in Computers | | Special Feature | Secure Connection | | UPC | 682017352046 | | Wattage | 75 | ## Product Details - **Brand:** Cable Matters - **Cable Type:** proprietary - **Compatible Devices:** Computer - **Connector Type:** 6-pin Pcie, 8-pin Pcie - **Special Feature:** Secure Connection ## Images ![6-Pin to 8-Pin PCIe Power Cable - Image 1](https://m.media-amazon.com/images/I/71nwQ7IHKjL.jpg) ## Questions & Answers **Q: What does this adapter cable do?** A: This cable converts a 6-pin PCIe power connector from your PSU to an 8-pin PCIe connector for compatible graphics cards. **Q: Which graphics cards are supported?** A: It supports GPUs with an 8-pin PCIe power port, including many models from Gigabyte, Radeon, and Sapphire. Always check your GPU's power requirements. **Q: Can I use this with a PSU that only has 6-pin PCIe outputs?** A: Yes, this adapter is specifically designed for PSUs with only 6-pin PCIe outputs to power GPUs needing an 8-pin connector. **Q: Is this cable suitable for laptops or non-PCIe devices?** A: No, this adapter is only for desktop PSUs and PCIe graphics cards. It is not compatible with laptops or other device types. **Q: Are there any power limitations?** A: Ensure your PSU can supply enough wattage for your GPU. Do not use this adapter to exceed your PSU's rated output. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Cables DO matter and these 6->8 pin adapters work right.
