StarTech.com PCI to PCI Express Adapter Card (PCI1PEX1)

I ordered 2 of these adapters because I wanted to use an old SCSI PCI card and a Sound Blaster Audigy 2ZS in motherboard which has no PCI slots. I was skeptical at first because many interface adapters I've used in the past "partly" work at best. I was pretty worried when I opened the boxes for these adapters and neither had a driver disk.However, I simply plugged the adapters in with the two PCI cards and the PCI cards were detected and installed flawlessly. It's been alittle over a month since I started using them and I've encountered no problems. I will note that if your PCI cards are not "low profile" You WILL need to cut away part of your case if there are multiple ports on the back of the PCI card. I used tinsnips to do this but a dremel would also work.Overall for windows XP/7 they work great, but the physical attributes of this adapter are clumsy. Just make sure you have a big enough case for this adapter before order. I didn't measure it exactly but I'd eyeball this adapter at raising the PCI card 1.5 to 2.0 inches away from the motherboard.

I bought this ages ago, but now I'm finally reviewing it. It works fine with Universal Audio UAD-1 cards, which is a pretty good indicator that it will work with anything since UAD-1s are notoriously finicky.There are two potential issues of which to be aware. First, since this adapter sits between your card and the motherboard, it adds about an inch to the overall height of the card. This could be a problem if your case is small and there isn't enough clearance. Luckily my 4U rackmount has plenty of space. Also, the card will flop around unless you find a way to secure it. I used a 2-inch long 6/32 screw and some spacers, but you may improvise with some cable ties or whatever else comes to hand.Second, this was not an issue on the UAD-1 card since it has no ports or LEDs, but if your card has a crowded backplane with ports, leds, breakout cables or whatever, it's possible that by adding an inch in height to it the ports could become inaccessible (or the card impossible to fit) without some not-so-minor case modifications. This is something to consider if you're hoping to salvage a pricy old sound card that has tons of breakout cables and/or ports.

The most important thing to know about this product is it will work in every system I am aware of regardless of BIOS/EFI or OS support. If you’re wondering why I can make such a claim its because your system already has these bridges in it; even if they are not currently in use. Most common modern chipsets and all current OSes (except perhaps a custom build) already implement this. This device simply adds another bridge through an expansion card device; instead of being on the mainboard itself. This also means any classic PCI compliant device should also works. But we know that’s not always the case. But don’t blame this adapter; if your addon card doesn’t work try it (and this adapter) in another computer. There’s also the possibility your card uses some odd sideband signaling or other uncommon features and may not work. In this case its unlikely even an onboard PCI slot in a modern computer will work.The downside of this adapter is its really only made to work with low profile PCI cards. If you’re looking to make this work with a full height card you’ll need to do some case modifications.I am currently using this in an external enclosure by means of a PCIe extender. I’m having good success with this method since the PCI bridge only operates over Gen.1 PCIe signaling.

This worked fine on my old computer

I purchased this adapter to work with the Avertv HD DVR High Definition / Analog Video Capture Card PCIe the I also bought at Amazon.Installation was very easy, however the PCIe card did not have any physical support on the adapter to to help keep it straight. It is possible to get it in there properly, but proceed cautiously. The card you are using this with must have a half height bracket to fit in with this adapter. The card I bought had this, so it was not an issue.Even seated properly, and confirmed several times, the capture card did not work well. Apparently it did get power and it did communicate through the adapter, but the input was such poor quality that it was useless. The video was barely recognizable. The capture card does work properly when plugged directly into a PCIe slot, so I do not fault the capture card. I needed this adapter since my graphics card blocks use of the PCIe slot when it is installed, so without this adapter working, I can have either my capture card OR graphics card installed on this motherboard. I assume there just isn't enough throughput with the adapter for this type of device and function. Based on my experience, I cannot recommend it, although with another, less demanding device it may work adequately. At ~$40 that may not be worth the risk.

Exactly what you need to get the Google Coral TPU mini PCIe version to work! Don't be tempted by thinking the cheap adapters will work as most of them are made for adapting a wireless card from a laptop or similar.

I bought this for my SFF machine that was missing an extra PCI-e slot, but had plenty of PCI ports. I used this in combination with another bridge to mount on an empty slot where the PCI-3x16 was missing where the PCI-e 16 Bridge was placed with a PCI-e 1x wire ran to this device. I then connected my video card to the pcie-16 bridge and my video card works with no flaws and the picture is as clear as it can be as if it was installed with no bridges. This device helps a lot and I see it working for whatever else you need to use, even if it's not a video card. Just a note, my addition pci-e x16 had extra power from the power supply so I don't know if that is what made the difference. i never tried this stand alone, but it worked really, really good for me. I've had this for 3 weeks now and still, No Complaints. Very happy.
