Kingwin Powered USB Hub 3.0 w/ 1 USB-C Port, SD Card Reader & Micro SD Card Reader - Sata Power Port w/Lightning Speed Data Transfer Up to 5Gbps - 5.25" Computer Case Front Bay, black (KW525-3U3CR)

I was able to install this in my desktop with no problems and all of the ports work fine. I'm happy with the purchase and would recommend this for someone with the larger 5.25 bay available on their desktop.However, there are a few items that should have been listed in the product description:- The card slots are only USB 2.0. This fact is listed if you look at the product pictures, but is not described on the product page. I was a bit disappointed with this but since all the ports work fine I'm going to keep the hub.- There is a molex power connection on the hub so you want to make sure you have an extra molex power connection available.

I installed this hub in a 5.25 inch drive bay and plugged it in and it just works. Got it to replace a USB 3.0 expansion card in an x1 slot that would have knocked my second X16 (that only runs at, x4 speed with my graphics card in slot 1) slot all the way down to x1 speed. It appears on 550 motherboards that if you have a graphics card installed in your primary x16 slot your second X16 slot only functions as x4 then if you occupy an x1 slot as well all PCIE slots except for slot 1 are knocked down to PCIE x1. These secondary slots except for the slot 1 graphics card slot are all PCIE 3.0 while the graphics card slot is 4.0. Pay careful attention to this when buying a motherboard in the future folks. I know I will. I consider this something of a serious limitation. The board didn't even have an x8 slot but has 3-4 x1 slots. The board in question is the ROG Strix B 550 F gaming. Great board just some limitations on the PCIE side of things. It's paired with a Ryzen 5 5600X.

Works great with the Kingwin Front Panel, I went from 4 UBS ports to11 ports. But the Kingwin Front Panel is a screw in unit, and a LENOVO THINKSTATION P520 is more of snap in type of set up, plus the Kingwin Front Panel is about 2mm all-round smaller the P520's opening. So, I going to use some 1or 2mm black modeling sheeting to build a box around the sides of the Front Panel and that should work fine.

In summary, I have to echo the complaints made by other reviewers:1) Cheaply made2) Poorly designed3) Does not work wellTo be specific, the unit cheapness of the unit can be seen in several areas. First off, as others have said, the attachment screws are cheap wood screws not machine threads and screw into smooth plastic holes, cutting the threads into the plastic holes as you screw. CAREFUL NOT TO OVERTIGHTEN as you will strip the plastic out.Second the circuit boards are fully exposed. Better made units enclose the circuit boards in a metal case with shield them from EMF interference and protect them. Saves them a few bucks = cheaply made.Third, the USB 3 cable coming out of the unit is way to short to reach anything inside a tower case - which is the type of case you would have with a 5.25 inch front panel accessory. So I had to buy an extension cable. But beyond that, the cable connector is a cheap piece of S**T and you can't tell if it is snugged properly into it's mate. Bad design... and CHEAP.Now, this I knew in advance and should have realized, but the card reader slots are on USB 2.0 and are Soooo SLOOOW. It was about 1/4 the speed I got with an external USB card reader I was trying to replace. So that's on me. But still, WTF? Why not have all slots go on USB 3? (The replacement I got did have card slots on USB 3).Finally, the icing on the cake was the damn thing didn't work consistently. Sometimes it would work fine and others it would lose the drive in the middle of copying a file.I know that it's hard to find a 5.25" card reader with USB 3.0. What I ended up doing was getting the 3.5" model from StarTech (35FCREADBU3) and a $5 adapter (BRACKETFDBK) to fit it in the 5.25" bay. Solid build and works like a champ at full USB 3.0 speeds across the board.Cheers!

This was exactly what I had been searching for. I wanted something with more than 5 USB 3.0 ports and this thing provides that.Now I did not have the connection on the motherboard to attach the wire they provide with it but I was able to use a USB 3.0 to USB 3.0 cable to attach it to my PCI cards internal port. I have not had but one issue with it. I noticed a couple of times over the past two months with this that my usb drive would disconnect and reconnect on its own, noticed from the sounds Windows 10 makes when inserting or removing a USB device. I chalked it up to not having the motherboard port to plug the cable sent with this item as the reason. I am technically only using one USB 3.0 port instead of the two that the cable provided would have connected to. I still gave it 5 stars because it does work great for what I need and its no fault of the product that I didn't have it connected the way it suggests.

I have had this for about 2 years before writing a review. Overall it dose a decent job, I don't need lighting fast speeds when I am just transferring data over to my phone and back, or plugging in a controller. What I really wanted this for was the TF card slot because I do a lot of 3d printing. My biggest gripe is that the plastic is not 100% flush to the port so there has been multiple times where I go to insert the card at a weird angle and it dose not go into the port but falls into the hub itself and I have to find a way to fish out my card. That annoyance alone would had gotten this a 4 star but where it loses another star is that the TF port seems to be really iffy. Some day I can slot in cards just fine and it reads, other day I have to fiddle with the port to make it work and other days it just dose not read. I say this is nice, but I feel like the only reason this has so many positive reviews is because they are basically the only one on the market. Its reaching a point where I think I'll just get a type C hub and find something else for the front bay drive.
