Why M.2 to PCIe X4 Extension Cable?
- Usually on a Mini-ITX motherboard, there is only one PCIe X16 slot for the graphics card. To get an extra PCIe slot, you can convert the M.2 slot on the motherboard into PCIe slot
- You want to move PCIe X1/X4 devices outside the motherboard because the motherboard space is too crowded, or the cooling on the motherboard is too poor
- How to use the M.2 Key M slot on the motherboard？
Advantages
This M.2 to X4 extension cable can convert to PCIe X4 interface, and extends to 23.6 Inch/60cm far away
It features with the following advantages:
- M.2 Key M slot converts to PCIe X4 slot, so you can install PCIe X1/X4 device to motherboard
- 10W power supply from PCIe X4 slot. If it is insufficient, 15PIN SATA interface is available for extra 54W power supply
- The length of 23.6 Inch/60cm can extend the PCIe X4 slot to any position of the PC case, even outside the PC case
- M.2 Key M converts to PCIe X4, but still PCIe X1 speed bandwidth. You can install PCIe X1 or X4 deivces on this extension cable

I have a Lenovo desktop model m91p with an Intel i5 processor and a graphics card from EVGA Nvidia 750 GT. The graphics card occupied one slot but the heat sink and fan extended over the PCI-e 1x slot so that I could not use the slot. The other PCI slots were available but most PCI cards do not work well with Windows 10. I am running Windows 10 Pro 64 bit. So, I looked at replacing my graphics card with one that only took up space for 1 slot. But, my graphics card was working fine. I had 2 GB of GDDR5. Something equivalent or better cost $90. So, I looked for a solution to extend the PCI-e slot. I looked at Ribbons but there design blocked the flow of air across the heat sink if I bent them 90 degrees. The GLOTRENDS design made more sense because the card that inserted into the slot was flush with the existing slot and did not interfere with the graphics card overhead. Also the cable extended back toward the rear and did not block any other slots. I purchased a Rosewill 4-port external USB 3.0 card and unscrewed the card from the bracket and flipped it upside down and reattached it to the bracket using standoffs so that I could attach it to the backend. It worked. I was able to attach the other end of the GLOTRENDS cable to the top and it fit snugly into the bracket holder. So, I was able to reuse the PCI-e slot. If I had tried to use the ribbon design, I would not have been able to successfully attach the Rosewill to the bracket holder. But, the true test was to run a benchmark on the new card. Above are the results without the power attached to the card. I need an extension for my MOLEX to finish the installation. But, everything is working fine without it. I am getting very good performance without the power attachment. I believe GLOTRENDS has the best design for extending the PCI-e slot for graphics cards that cover the slot.

Here's my combo solution review for the SUPEERPLUS PCI-E 1X to Half/Full Mini PCI-E Adapter and GLOTRENDS 1X to 1X PCI-E Extension Cable UEX101:My goal was to add a DIY eGPU to a Dell Optiplex 7010 USFF (ultra small form factor) PC. The project also included other parts including a 16X/1X USB mining riser, and server power supply with a 12volt mining breakout board. Only 1X PCIE was needed as using for GPU password recovery as part of cybersecurity training and work. My son upgraded GPUs in his gaming rig, leaving me with a GTX1060 6GB for my project.Originally my plan was to use the mPCIE in a Dell laptop (E7440), but that went bust when the laptop would NOT recognize the card. It was the WLAN/WiFi slot, and there must be a blacklist/restriction on cards in that slot even though I was hoping there was not. So I went a different route. The Dell USFF was on hand from a previous project, and I don't have the want, or deskspace, for a mini/tower PC. Plus this could be an easily mobile solution with the size of the devices. Space in the USFF is TIGHT. I spent a lot of time researching, comparing, and looking closely at product pics and videos online until I was more certain the parts would fit. I decided to go with a USB-based solution rather than ribbon-cable mPCIE 1X extender. I ended up not using the PCIE 1X slot card that ships with the extender, rather I just extended the USB cable all the way out of the chassis, via an open external WiFi antenna slot already cut into the case, then extended using an Amazon Basics USB 3.0 extension cable directly to my 16X riser. The USB cable is much more sturdy, and I would be concerned with a thin ribbon doing the same thing. That, and I really don't think there would be any space for a 1X slot extended via ribbon elsewhere inside the case, without leaving out a RAM DIMM to gain space.These items worked perfectly!! I don't think that any other solution could have worked as well. The power connector on the mPCIE, with cable connected, is the highest point, and am sure is being pressed by the seated drive cage. The right-angle USB was the only way to get a solution like this to fit, and the cable reaches inside and out of the case to where I could anchor the USB cable onto the case padlock loop on the back. Yes it did take some packing to get all the cables in. Actually 3 attempts before I could get the cage seated and top panel back on. But it all fits! And works!!

Got this to set up my pcie wifi card in a Thermaltake S100 TG mid-tower case in vertical riser mode to mount along side my vertical video card.The expansion slot mounts in this case have the option to be rearranged vertically. I didn't want to waste my perfectly working wifi card and get a USB wifi adapter. This extender is both a great work-around and cost efficient way to keep my setup.Only problem I have with it is that the USB cord is probably twice the length I needed. So it had to be snaked and coiled around a bit through various cables and jumpers on the motherboard and the vertical mount. It is a very thick quality cord to manipulate and it is not pretty, but since the wifi card is mounted behind the video card (with it's own rather lengthy pcie 16x riser cable), you just don't notice the slight mess.Overall it works out fine. No problems with functionality. Again, for my application, it's just a bit too long. If you have a full-tower or need to snake a pcie 1x expansion around a mini-itx setup, this should do the trick. I may optionally get a shorter cable in the future.

This worked WONDERS!!I had been gifted a Wi-Fi card for the holidays, but when I saw that my GPU covered my PCIe x1 slot, I sprung for this.The side that plugs into the motherboard was so thin that I kept fumbling it a bit trying to get it seated (fat fingers, ugh), but it cleared my NVIDIA GeForce RTX 2060 with no issue!The actual Wi-Fi card is only attached to the back of the case which I don't like, but it's not like it's going to sag.

This device looks perfectly fine. I love the design, cable length, rubber foam under the connector, etc., however, it doesn't work. The computer won't start when the adapter is present. I tried reinstalling it, unplugging and re-plugging the cable several times to no avail. Unfortunately, I don't have another PC to test it with, but I have a different adapter that uses the same port, and it works fine, so this is definitely this adapter. Sadly, I'm going to have to return it. I really wanted it to work because I need it for a project that I'm working on, but it is what it is.

This allows me up install bigger components outside the tight area of the pcie slots.

Muy malo, deja el ordenador absolutamente colgado al minuto de encenderlo y se reinicia. Ha sido quitarlo y de nuevo el funcionamiento es normal. No es nada recomendable, las caracterÃsticas de mi PC son 32 gigas de ram, Placa Gigabyte B450M DS3H con microprocesador Ryzen 5 de 3600.Ni se os ocurra comprarlo

Quando ho acquistato questo cavo di prolunga, avevo messo in conto che fosse un esperimento non necessariamente destinato al successo, per tante ragioni legate alle reciproche compatibilità dei componenti.Mi piacerebbe capire perché, ormai, girano quasi solo schede video a doppio slot e schede madri che hanno una porta PCIe-1x immediatamente sotto alla PCIe-16x, e quindi irrimediabilmente destinata a rimanere coperta ed inutilizzabile.Lo scopo era quindi, da un lato, recuperare la porta PCIe-1x rimasta nascosta sotto alla scheda video a doppio slot.Dall'altro lato volevo aggirare la fregatura rimediata con la scheda madre Asus Prime B350M-A: il chipset prevede la condivisione di banda tra la porta M.2 e le porte SATA 5 e 6 (dettaglio che mi era sfuggito), quindi, quando ho trasferito il SO dall'SSD SATA su un SSD M.2 NVMe (attenzione! gli M.2 SATA non vanno bene), ho raggiunto, sì, un eccellente miglioramento prestazionale (è un Samsung 970 EVO... chapeau!), ma mi sono trovato porte SATA 5 e 6 (il secondo HDD dati ed il lettore DVD) disattivate.Io avevo la pretesa di continuare ad usare entrambe le periferiche, ed ho cercato una soluzione globale per i due problemi, trovando la prima qui: il "cavo" è un complessivo, formato da una micro-scheda ribassata che si colloca nella porta PCIe-1x rimasta sotto al corpo della scheda video (non ci sono fermi, in mancanza della staffa di fissaggio allo slot posteriore, ma il contatto PCIe-1x è sufficientemente stabile di suo), ed ha una presa USB 3 ribaltata, in modo da non toccare la scheda video sovrastante, un cavo USB 3 sostanzialmente "normale" e di lunghezza ottimale, ed uno slot PCIe-4x "volante", con una basetta provvista di feltrino, da posizonare/incollare come si può negli spazi liberi del case.La soluzione del secondo problema mi è stata fornita da una scheda "Syba SATA III - Scheda PCI-e 2.0x a 2 porte eSATA III, con Marvell HyperDuo" (https://www.amazon.it/gp/product/B00AZ9T31I/), e questa scelta è meritevole di recensione e 5* a parte... sì, perché, oltre ad ogni mia aspettativa, ho centrato perfettamente l'obiettivo, pure con ulteriori opzioni extra; ho, quindi, scelto per il cavo la versione PCI-e 4x, perché quella 1x non bastava per la scheda PCI-e 2x.Il mio (dichiarato) accrocco compensativo ha funzionato perfettamente da subito, senza il minimo problema, ed ora mi ritrovo con le periferiche ora recuperate e due porte eSATA supplementari posteriori, che ho già in parte opportunamente utilizzato con grande soddisfazione.L'esperimento, partito come azzardato, è perfettamente riuscito, e lo consiglio a tutti quelli che hanno problemi (o fissazioni) come le mie.
