Good construction quality

Reviewed in the United States on October 1, 2023

Verified Purchase

I ended up not needing these, as the GPU I bought had a 6-pin connector while the photos I saw online of similar models of the same series all have 8-pin connectors. I wanted to be ready when the GPU was delivered. I went ahead and kept them for the future. The construction quality is very good as I have built a lot of my own cables with similar connectors so I know what to look for.

Cables DO matter and these 6->8 pin adapters work right. Do not heat up like cheapos I got elsewhere

Reviewed in the United States on July 31, 2023

Verified Purchase

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.

good solution as long as you understand the limitations

Reviewed in the United States on May 27, 2020

If you have a smaller power supply that supplies a 6-pin PCI-e connector and a graphics card with an 8-pin connector, the adapter will let you PHYSICALLY connect your PSU to the graphics card. Keep in mind that a 6-pin cable is for supplying up to an additional 75W to the card, and using this adapter will not magically increase the limit to that of an actual 8-pin cable which would be an additional 150W.

To determine what graphics card you can use, you also need to know how much power can be drawn over the PCI-e slot your graphics card is plugged into (typically 75W, but less for some small form factor PCs) and also what your power supply is rated to supply. So you need to do your research and confirm the specs. Understanding these constraints, along with options provided by software like MSI Afterburner to limit the peak power consumption of a GPU, you can safely use this adapter with an appropriate graphics card.

For my personal case, I am using this adapter for an EVGA GTX 1660 TI (8-pin PCI-e connector) connected to an HP Z240 Tower workstation w/400W 80+ platinum rated PSU (6-pin PCI-e cable/connector). For the Z240, I would want to keep the power draw of the GPU under 150W (75W over the 6-pin PCI-e from the PSU+ 75W over the PCI-e slot). The EVGA card (which is overclocked compared to reference Nvidia) spec says the power draw is up to 160W. So I use MSI Afterburner to power limit the GPU at 90% to keep the max power draw to under 150W.
