Was assisting a friend in their computer build when we ran into a snag. The existing Power supply cam with two 6 pun connectors and the Graphics card we were planning to mount required an 8-pin connector. This cable solved the issue, a simple P-N-P. Worked out of the box, no gotchas.

No complaints from me or my video cards. No funky smells when heated up as some of the others I've tried. Good price and quality, plus it fit my need for 2 computers. Currently running with a GTX 1080 TI and an RTX 3070 in 2 different systems, no issues or excessive wiring length to manage.

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.

I needed to go from a Six-Pin Connector to a Eight Pin Connector I.E. AMD Radeon RX480 4GB to Sapphire Pulse RX580 8GB, and this fit the bill. No problems at all. Power Supply more than adequate, Build is a GX-785 by Acer. Build limited by I5-7400 Processor and Skylake Motherboard. Do not care to upgrade beyond 64gb RAM and 500gb Samsung NVME drive. Does what I need it to, and many people play the lower spec games on high end rigs anyway.

Ground yourself by touching metal case before moving graphics card out. Be careful of components. I had to turn my PC sideways because the card has heft to it, (and my connected two 120mm fans with negative pressure on the case,) to make sure that it would not destroy itself due to gravity. Works well. Did install the power connector after it had already been placed, in the future I would advise the connector be placed on the card before install however I had no problems doing it this way.

This even came with two connectors, so I'm trying on another low budget build next with other components.

Simple, effective.. did the trick

Reviewed in the United Kingdom 🇬🇧 on August 30, 2020

Verified Purchase

Although this came as a pack of two, I only needed one but I'll admit that I was at the end of my rope by the time my little "apprentice" found them.

To cut a long story short I have a workstation that while still hugely powerful by today's standards, wasn't fitted with the infernal eight pin PCi express power connectors. In fact, until I went to fit my pre-loved 1080ti I had no idea such a thing even existed. (I've been retired for a number of years now and haven't kept up...)

So in goes the 1080 and in goes on six-pin PCi power line and ... oh shirt! Wait that's not a six pin socket - and it wasn't about to let me fit the extra six pin power which was originally intended for a second card in an SLI configuration.

Oh woe was me, I'm stuck with the aging card that I'd got years back and wasn't really up for SLI... first option we found, also on Amazon was less than ideal - a pair of Molex-to-PCie 8-pin. While that would have worked (the PSU is more than capable of providing enough power - the cable runs would have been rather long and ugly.

Enter these little beauties. They're only short (about four inches in old money) and connect the older 6-pin PCie power converting it into an 8-pin affair.

Long story short, I now have a happy computer and I can learn to fly in FS2020!

Thanks Cable Matters, you saved my sanity!

Reviewed in the United Kingdom 🇬🇧 on October 25, 2022

These were bought for a new graphics card that needed 8pin connectors, and they work fine. They are obviously cheaply made but certainly nothing that would cause any problems. I am running them with a 3060Ti that pulls 240W and they don't get overly hot or anything like that.

The moulding and finishing are fine and will stand up to several plug/unplug cycles.

Overall not bad for the money, and I would buy these again if needed.

Not all PSUs are the same - these adaptors give you options.

Reviewed in the United Kingdom 🇬🇧 on July 3, 2020

Verified Purchase

My (850W) power supply is modular, with multiple PCIe 8-pin connectors. But all of the cables supplied reduced from 8-pin down to 6-pin. Fine for my old graphics card, but not for the upgrade which wanted a 6-pin and an 8-pin.

Instead of waiting weeks to get a replacement cable, I bought this pair of adaptors that go from 6-pin back up to 8-pin with cable loops. They arrived the next day, and a little while later the new card was installed, powered, and I was a happy camper. Nicely made and the connectors fit easily but snugly. This was the best solution I could've hoped for.

If you have a GPU with an eight pin power connector and you only have a six pin feed free this is what you need.
For me a twin pack was spot on as I was installing two cards running in SLI mode but at this price if I only needed one I would still have made the purchase and kept the second as a spare.
