Fast, no conflicts, works perfectly. - Great product. Will buy again for sure. Review: Works well with Esxi and Server 12 - The FS-4C-U8S-Pro is a newish (2019), Pcie Gen 3, low profile, well designed (big heatsink), four channel USB 3.0 host bus adapter. The low-profile design dictates the horizontal port placement, which some reviewers have found problematic in aligning with case slot openings. My experience, with a Lian-Li server case, is the port connector fit is snug but perfectly serviceable (try plugging in the cables before tightening the retaining screw). In addition to the 4 external ports, there are two 19 pin headers for attaching another 4 ports (though those will share bandwidth with the externals). There is also a SATA power header to provide more amperage to the ports, should you be connecting USB powered disks or other power-hungry devices. The controller chip used is the Renesas uPD720202, one per channel. My environment is an Intel 8700K CPU running VMware Esxi 6.7 U3 Free as a host OS, with a Windows Server 2012R2 VM and a couple of low use Windows 10 VMs. Performance is what I expected for rotating hdds: 200/208 Mb/s single disk, 240/258 Mb/s Raid 5 measured with ATTO, and no degradation on simultaneous usage of all 4 ports. The heatsink does a good job of keeping the chip operating temperature at 95° F in a well-ventilated case. I perform two types of daily backup to four USB 3.0 raid enclosures attached to a Server 12 Esxi VM (about 3 - 5 Tb per day). The motherboard USB controllers were unreliable in heavy usage, regularly dropping connections during backups. I tested 3 quad channel (Pcie x4) adapters in my quest to obtain reliable USB 3.0 connections for my server. This was the only card that I could get to work. It works reasonably well with individual USB devices assigned through VM settings, occasionally (randomly) dropping a device, but it works great with PCI device passthrough configured. To get passthrough configured, I had to set the ‘VMkernel.Boot.disableACSCheck’ switch to True. I have been beating the heck out of this thing 24 hours per day for a week now, and no dropped devices or failed backups. UPDATE: 1 1/2 years later and everything is still good. 100% port reliability. No issues. ## Features - 1. FS-4C-U8S-Pro is a PCIE X4 interface to 4 channel 8-Ports USB 3.0 expansion card.

Fast, no conflicts, works perfectly. *by L***I on June 30, 2026* Great product. Will buy again for sure. ### ⭐⭐⭐⭐⭐ Works well with Esxi and Server 12 *by D***L on July 12, 2021* The FS-4C-U8S-Pro is a newish (2019), Pcie Gen 3, low profile, well designed (big heatsink), four channel USB 3.0 host bus adapter.

No issues. ### ⭐⭐⭐⭐ MUST HAVE MORE PORTS! *by K***N on June 9, 2020* I seem to be a peripheral packrat, and had run out of ports after filling up the 6 on my motherboard and 4 case ports. I could have bought a USB 2.0 header or two, but really wanted to avoid having a big mix of different port speeds. Installation is dead simple. Slam it in the slot, close your case, and you're pretty much good to go with Windows 10. I didn't run into any unusual resource constraints while using this with USB SSD's to test I/O, and speeds were what I'd expect from USB 3. The only thing I found disappointing was that they don't include the 2x2 headers that make this the 8-port card they advertise it as being. It isn't like they're expensive, and as USB cards go, this is kind of an expensive one... so I was a little put off by that. Otherwise, it's a solid buy. ## Frequently Bought Together - FebSmart 8-Ports PCIE Superspeed 5Gbps USB 3.0 Card for Windows and Linux Desktop PCs, 4X Dedicated 5Gbps USB 3.0 Channel 20Gbps Bandwidth, Built in FebSmart Self-Powered Technology (FS-4C-U8S-Pro) - ICZI USB 3.0 Hub, 4-Port Date USB Splitter Adapter for MacBook, Mac Pro/Mini, iMac, Surface Pro, XPS, Laptop, Flash Drives, Mobile HDD --- ## 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.sn/products/164056367-8-ports-pcie-superspeed-5gbps-usb-3-0-card-windows](https://www.desertcart.sn/products/164056367-8-ports-pcie-superspeed-5gbps-usb-3-0-card-windows) --- *Product available on Desertcart Senegal* *Store origin: SN* *Last updated: 2026-08-22*
