2-Pack 6 Pin to 8 Pin PCIe Adapter Power Cable - 4 Inches

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.

Highly recommended from Amazon. Works perfect without any issues. No over heating.

I have a XPS 8900, wanted to install a RTX 2060 but found the PSU only had a 6 pin connection. With this, I was able to plug in the adapter and install the video card. Works great!

Got a new gpu and didn't want to buy a new power supply just yet. This adapter was a perfect in between until I can afford a new psu. Arrived quick and showed no problems so far. However, I was warned that anything that consumes an absolute ton of power (the card that was given to me as an example was the 3070) should NOT be used with an adapter, since it consumes more than the 6 pin connector can provide. There is a reason and a limit for the 6 pin connector. If your looking at this item, make sure the graphics card you want/are using doesnt consume more power than what the 6 pin connector can provide. For my purposes however, it fit great and was easy to install. The quality felt professional and the price was amazing for what it is!

I needed the adapter to upgrade my nephews PC from an RX480 to a GTX1070. I ordered these and they arrived the next day. I was a little concerned about whether this adapter would deliver the power consistently since we're not adding more rails, just splitting existing rails. Upon installing them, after a strange glitch on the initial boot, the PC started back up without any problems, seemed to work just fine. Time will tell how they hold up, I certainly wouldn't install these on a GPU I couldn't afford to replace pretty easily, but they seem to do the trick. The only things you may have an issue with are cosmetic, they're ugly, but if you're using one of these you probably weren't doing an aesthetic build anyhow.

Upgraded my GPU from a 1650 to 4060 and didn't know it was 8-pin only while my PSU only has a 6-pin. The computer didn't even recognize the GPU, I was so upset! After an embarrassingly long time looking for solutions, I figured I should just spend the $10 on an adapter cord. Got it in 2 days, plugged it in easily with no problems with the connection or quality of the wires, hooked up my monitor to the GPU and after opening my driver's and refreshing, I swear I heard the hallelujah chorus as the 4060 appeared under my drivers. I booted up FFXIV to test it and the difference was like night and day. Well worth the $10 and you get two of them!

Very nicely put together. Quality product, no defects.

My youngest wanting to keep up with his sisters on Roblox at 5years old complained about lag and stutter. He being the youngest has the oldest PC in the home - which was a older Dell i7 desktop serviced purely by on board graphics. So having a spare 2060 sitting around and as no surprise found the Dell OEM power supply only had 6pin PCIe connectors - so used this adapter to connect power to the 2060 8pin port. So from start to finish 5 minutes and I was back into windows downloading new drivers. Worked perfectly for me and getting smoooth gameplay and peace of mind now that this little guy has stopped harassing me for an upgrade. Woo Hooooooo!

Works really well - received two of them for less than it costs for one at the local PC store. I was dubious about that; but it handles the conversion no probs.

La qualité a l’air au rdv! Bien emballé, avoir dans la durée ce que cela vaut

Much better quality than others for sale. Thick gage wire that’s well insulated and does not get hot at all. Using it to power a RTX 3060 off a 6pin and has been working perfectly for 6 months

Used it for a vega 64 in my z620 workstation and they work fine. Be carefull when using these though because regular 6 pin cables can only deliver 75 watts (same for the pcie slot) so when using 2 you shouldnt use a gpu that uses more than 75*3=225 watts

Worked as expected on my gpu that needed an 8 pin pcie.
