StarTech.com PCI Express X1 to X16 Low Profile Slot Extension Adapter - PCIe x1 to x16 Adapter, TAA (PEX1TO162)

I needed a way to add a graphics output to an already full server. This allowed me to attach a low profile cheap graphics card to the only 1x slot I had left. Now i have video output when needed on the cheap.

I used this to put a PCIe 2x half height 10G NIC into a PCIe 1x slot on a motherboard with full height case slots. Worked perfectly fine and got full speed. Functionally, it should work great for any half height card even if they have the full 16 lanes on the connector. But since the wiring is only there for the 1 lane, that's all the speed you'll get. But that also leads to one of my criticisms. Since this is really just a PCB and traces, no conversion chips or anything expensive, the price was a bit high. Similar M2 and SATA adapters are usually under $10. The other criticism is that due to the different bracket screw hole locations between full height and half height cards, there's no way to use the half height bracket to stabilize the card. Both the adapter and the half height card just rely on friction to stay in place. The higher price on this adapter would have been fully justified if some sort of adapter had been included to anchor the adapter card in a full height slot that also let the half height card bracket screw on to. For my use, I just used a sheet of kydex and screwed both the adapter and the NIC card to it. Then I cut the end off a full slot blank to attach as a screw anchor point. Looks janky, but anchors it in place well. If you have the need, it functions well as long as you can live with the anchoring / attachment shortcomings.

I already had a graphics card, but only had PCIe 1x slot available. This adapter is exactly what I needed to use the graphics card that I had in the slot that was available. Graphics Card: AMD Radeon HD 6450 Motherboard: Gigabyte GA-870A-UD3 I actually have it plugged into the x16 slot, but I need the other x1 slots active and to do that on this board the x16 slot can't be in use. So this did the trick without having to upgrade the motherboard yet. Running 4 monitors total now. 1 monitor attached to this card. Using it for productivity / web browsing. I had a 720p video running on it to test and it looked fine.

I'm using this card in my Dell XPS 9100 to add a 2nd PCI x16 graphics card (an HIS Radeon HD 5450) to power a third monitor. I had no problems whatsoever with this adapter. Windows 7 x64 Professional detected the new graphics card immediately and the existing ATI driver for my Radeon HD 5600 card worked just fine. Would definitely buy again as needed (although I'd certainly try and get a PC with more x16 slots next time first!)

It did not meet my needs so I sent it back & got a ASUS STRIX SOAR Sound Card, in stead of trying to get my legacy sound card to fit in a PCI.E slot,

I tried to use this to replace a video chip that did not have a driver for Win 7 64. It plugged in and the PC found the nvidia 610 video card on boot. Unfortunately I kept receiving "the video driver recovered from an error" whenever the video became saturated. I had to purchase the more expensive adapter card with the outboard power connector to make the issue go away. This does work as advertised but may not be for video applications.

Expensive, but it works! Used it with a Gigabye 965P-DS3 motherboard and MSI ATI Radeon HD5450/512MB/DDR3. I had to use a low profile bracket in order to screw the card to the case. Doing this will drop the performance of the card considerably. Don't expect to play 3D games or play HD videos. No problems with Windows 7 Aero and dual monitors.

Technically, this does exactly what it should. You can plug up to a 16x low-profile pci-e card and it will "fit" in a full-height slot. I put a little gt730 gpu in an otherwise headless homelab server's 1x port. Worked fine for simple setup when you need display during setup or troubleshooting. As others have said, the problem is that half-height pci-e brackets face the opposite direction. So, you can't actually use a short slot cover in a full height case. This means the cards will flap around and you'll need to be careful if you plug something into or out of the card.

Appareil non fonctionnel. Il est néanmoins possible que cela soit du à un défaut du pilote de la carte (ajout de port USB) introduite sur le socket femelle du PEX1TO162. Donc prudence avant l'achat

Ho acquistato questo prodotto al fine di poter utilizzare una scheda di espansione silverstone usb 3.1 con pci-e x2 anche su un pci-e x1. Infatti dopo aver montato gli m.2 samsung (che richiedono un pci-e x4) mi erano rimaste solo pci-e x1 sulla mia Asus z97-a e cercavo proprio qualcosa di simile per non dover accantonare componenti che hanno sempre funzionato bene. Il pacco è arrivato nei tempi e ho provato subito a montarlo ma inizialmente non funzionava nel pci-e x1 mentre funzionava perfettamente in uno dei pci-e x16. Ho avuto il sospetto che il pci-e x1 non erogasse una corrente sufficiente e ho provveduto perciò ad alimentare il Silverstone separatamente . Inoltre , al fine di far funzionare il tutto anche su pci-e x1 ho dovuto entrare nel bios della mia Asus Z97-a e andare in Advanced/Onboard devices configuration e selezionando PCIeX1 (in PCI Express slot and M.2) Tutto ha iniziato a funzionare e subito ho testato una sdxc per vedere le prestazioni in scrittura e lettura. In allegato ho postato gli screenshot. Risolto il problema ho notato che l'attacco però risultava piuttosto ballerino in quanto il nuovo spessore rendeva inutilizzabile la piastra di fissaggio in metallo a cabinet e motherboard. Con una fascetta da elettricista ho fermato il tutto anche se il bloccaggio non è ottimale. Se come me avete bisogno di utilizzare schede pci-e x2, x4 o x16 su un piccolo pci-e x1 questo è quello state cercando. Ovviamente è una soluzione un pò ballerina e bisogna adattarsi.

Had it running about a week now. So far nothing has caught on fire, despite having a fairly beefy GPU plugged into the thing. GPUz reports that it's happily running at PCIe 4.0 (x1, of course), but since the GPU'ss workload isn't exactly IO-heavy, I've no idea how stable that is. My only complaint is there isn't a good way to mount it to the case, but I'm not sure that would even be possible without interfering with whatever you're plugging into it.

Kurz und knapp, neue Grafikkarte, blockierte mir den einzig freien PCI-E 16 Slot für meine OPTANE SSD. Adapter verbaut, funktioniert...allerdings schaut das ganze ziemlich fragil aus, keine Ahnung ob es da eine bessere möglichkeit gibt das ganze "stabil" zu befestigen...

Funciona muy bien. Si tienes un bus PCIe 1x libre podrás conectar tarjetas de 8x o 16x. Obviamente no tendrás la misma capacidad pero vale para tarjetas gráficas y de red. Siempre con las expectativas razonables de no llegar a los 10G en transferencias. Otro punto importante es que la medida es la justa para encajar una tarjeta de perfil bajo en una cajas normal sobre el PCIe, de tal forma que puedas atornillarla o cerrarla sin problemas. En una tarjeta de red es importante... Por otro lado el único problema es que es cara. Pero no hay nada equivalente en el mercado. A mí me ha funcionado con una tarjeta de red Mellanox de 10G, aunque sobrepasa ligeramente la capacidad del PCIe 1x va de sobra.
