Easy to install and Windows 10 Home picked it up straight away without any manual intervention for driver installation. Initially, one external drive failed to show but reappeared after a reboot (probably my bad trying to relocate all the cables in one go). Since there are a multitude of hardware and other variables that can impact transfer speeds, I can't make any definitive comment other than file transfer rates are as good as they were. Rather than sit there with a stopwatch bemoaning speeds, I prefer to so something more worthwhile with my time.If all you want is more USB sockets then this item fits the bill admirably.UPDATE: Had no problem moving files around 100MB to external drive but ran into problems copying a 6.5GB file. That generated a semaphore timeout error which locked up my file browser and even Task Manager couldn't budge it (unfroze it by powering down the external drive). Turned out it it did need the supplied drivers installing and now working fine. ### ⭐⭐⭐⭐ So far so good *by C***H on Reviewed in the United Kingdom on 22 November 2019* Bought this as a replacement for the old USB3 card I had in my PCI-E slot. It arrived on time and was well packagedInstallation* This card was an absolute pig to install, I do not know why it wouldn't go into the slot but it really had me swearing, as a last resort I had to very carefully bend the metal plate at the bottom a millimeter or so and finally it clicked in.* Power was easy to connect and the power splitters / plug converters were useful* Drivers were easy to install from disk and worked first time.Usage:* The card has been working well since purchase without issue* Works quickly as it allows me to use the full 200mb connection rate for the internet through my dongle* Can't comment on longevity yet as I've not had it long enough, should it start to fail like the other one, I will update my review but so far so good.Compatibility issues :* Just the one, for some reason it doesn't like my Corsair gaming keyboard. As soon as I start tapping keys it disconnects and reconnects, however I'm using my USB 2 connections for this now as it doesn't need the speed so not a problem for me.Summary :Can't complain really, couldn't give the card 5 stars due to the pain of plugging it in, and the compatibility issue, but for the price and it's reliability so far, I haven't got much to complain about. ### ⭐⭐⭐⭐⭐ 4-port USB 3.0 PCIe card - works using supplied drivers *by P***N on Reviewed in the United Kingdom on 1 June 2017* These reviews seem to be for different devices. This for the 4-port USB 3.0 PCIe card.It was supplied with instructions in English, French, Italian, Spanish and German.I was surprised that my Windows 10 installation did not recognise an extra device installed on the motherboard, even an unidentified device, but a search on the CD found a setup.exe file, not as described in the instructions, which I ran, the drivers installed straight away, and a USB card reader that I connected worked.In the device manager the card shows as a Renasas Electronics USB 3.0 Host Controller and a Renasas Electronics USB 3.0 Root Hub. Don't know if these are the best drivers but they work for me. --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.co.uk/products/48568786-csl-3-0-usb-4-port-pcie-interface-card-pci](https://www.desertcart.co.uk/products/48568786-csl-3-0-usb-4-port-pcie-interface-card-pci) --- *Product available on Desertcart United Kingdom* *Store origin: GB* *Last updated: 2026-05-26*
