ELUTENG PCIE USB 3.0 Card 7 Ports PCI Expree to USB Expansion Card Super Speed 5Gbps PCI-e USB3 Hub Controller Adapter for Windows 11/10/8/7/XP/Vista

I purchased this PCIe USB 3.2 card for reliable USB connectivity for UPS COM ports, microcontrollers (Arduino/ESP), and general peripherals in my workstation. I do PCB repairs and inspecting the hardware, this card turned out to be one of the best-engineered budget USB cards I’ve ever used. Why I Chose This Card: Dual Renesas Controllers (uPD720201 + uPD720210) Industrial-grade USB controllers used in servers and professional hardware. Windows 11 recognized everything instantly with no drivers needed. GPU-Style 4R7 Power Inductors The same type of inductors found on GPUs and high-end VRMs. Excellent power filtering and stable 5V output. Solid Polymer Capacitors (220µF 16V) Low-ESR caps with outstanding ripple handling and long lifespan. Far higher quality than cheap electrolytics on most USB cards. PCIe 12V → 5V Buck Converter (No SATA Power Needed) The card regulates its own 5V instead of relying on the noisy SATA rail. This results in clean voltage and zero USB resets under load. Clean PCB Routing & ESD Protection Matched differential pairs, proper grounding, and filtered port clusters. The engineering is clearly above average. Plug-and-play detection UPS COM ports and microcontrollers work flawlessly No disconnects, brownouts, or enumeration errors Stable under simultaneous flashing and data transfer Compared to StarTech $66.99 StarTech uses: - A single VIA/Fresco controller - SATA 5V power input - Standard electrolytic caps - Shared bandwidth This $27.99 card is objectively better-built and more stable in real-world use. If you need stable, clean, reliable USB ports for microcontrollers, UPS serial ports, or just expanding your system, this card is an incredible value. For $27.99, the engineering quality is surprisingly high. I suspect people have problems with this card because of the OS or don't understand CPU/PCI Lanes in PCs. At this price range stop looking this is the best one. Highly recommended.

Seems to work great so far, but had a couple of issues with getting it to work initially. I first shut down my machine (Windows 11 Desktop) and installed the card. Upon trying to insert a cord into the slot furthest from the motherboard-facing side, I found that the card was misaligned. Easily fixed by simply inserting a dongle or cord into that slot prior to screwing the card down (NZXT H510 Flow Case). Then, when I logged in and checked the device manager, I was getting PCI Express resource errors. Okay, maybe I needed those disk drivers after all? Problem is, I don't have a single disk drive in the house. A quick Google search of the text on the disk revealed a file dump on Archive.org (Search: SSU PCI-E Card Drivers V200504 - Disc Dump and Scans). Mounted those with a separate piece of software (ironically flagged as malicious by Windows Security), but the install failed on both of the driver sets I tried. The piece I was missing was that I had to update the drivers in Device Manager and *manually* choose the (generic?) driver that came with Windows (Renesas USB 3.0 eXtensible Host Controller - 1.0 (Microsoft)). Either way, it seems to fully work now. The physical card fits in snugly, doesn't require any additional power connectors, seems to provide the advertised speed, and the USB ports hold onto connectors quite tightly.

The product itself is inexpensive, and you do get what you pay for so I'm happy: There are 8 ports as advertised, however only 1 given port can actually be truly 3.2 gen 1, since the total bandwidth is one single link to one single chip. most of the 8 ports are daisy-chained from the first USB chip, which is the only one actually connected to PCIe Gen 5. If you just wanted a handful of functional USB ports for basic peripherals, this will do the job, I'm not sure about high-speed stuff. If you're thinking Oculus Rift... maybe I'd only use one port for an auxiliary camera, and I'd use the ones closest to the PCIe edge connectors. For a decent price you get a handful of USB ports that might slowly charge your phone but will definitely be fine for general use that won't saturate the overall link. The chip on mine is a Renesas that is pcie gen 2, 5Gbps is the limit. None of this was a deal breaker for my needs, but the packaging could have been better, and some clarity on the card layout too. Fortunately, it was shipped well. Its inexpensive and worked out of the box with Windows 11, no drivers needed to download or install otherwise. As basic as it gets and that's all I wanted.

Drivers were detected automatically on boot. No additional power cable needed. Installed on HP ProLiant ML350p Gen 8 server running Windows Server 2016 with no issues. The server fans run at normal speeds. Was able to achieve read+write transfer speeds from WD MyBook 8TB at a steady 200-210 MB/s (large 200GB files). Seems too fast to me as I believe the MyBook is running a 5400 rpm HDD but also manually timed the transfer to confirm. Installed in a PCIe x4 slot (3.0).

Using this card in Windows 10, plugged it in, and it was detected and worked straight away. I'm getting good speeds through the ports and chose this card as it didn't need any additional power cables.

Great card. My computer started losing power to the usb ports. I say this and the reviews so I bought it. It works great and has 7 ports. Price is right. Bob Barker would approve

Price is high. Otherwise good.

Given how cheap this is, I was expecting something pretty flimsy but functional but I was surprised. The PCB is thick and heavy and doesn't feel like something as cheap as it is. Worked immediately and at proper speeds with no need for drivers (Windows 11). It does come with a driver cd which I have to ask, why bother? A piece of paper with a QR code or website is more functional than a CD few can use because very few computers still have cd/dvd drives. It also came with a small screwdriver and IO screws which is a nice touch. For only 30 Canadian rupees this is well made and comes with everything you need to install in the box (useless driver cd aside).
