Date Issued: 20th Oct 2008

A motherboard’s main job is to act as a conduit between the various hardware elements that make up a PC. It needs to be able to link the desired CPU(s), system memory, graphics card, hard drive(s), and add-in cards and enable them to work in harmony.

4 Port Silverstone SST-EC04-E PCI Express Card with 4x USB 3.0 is rated 4.0 out of 5 by 7.
Rated 4 out of 5 by from Works in Windows 10 and Linux, bought 2 but 1 faulty I needed more USB ports. I could've got a hub but most of my PCI-Express slots are empty and this has the advantages of being a separate controller, powered by the system PSU (without needing another power brick like you'd usually need with a hub) and also not needing to find a place to put a hub so that it doesn't look untidy. The card provides 2 internal ports and 2 external ones, fortunately this is clear at least from the picture. The card needs to be connected to a SATA power connector. The internal ports are not useful to me but if you have a case with USB3 ports at the front but no native support on your motherboard for it, it'll probably help with that. Windows 10 automatically detects it and installs the necessary drivers on startup, so it was pretty much "plug and play". So far I have only been using it within Windows 10, however I have looked online and it seems the chipset is supported by Linux. Booting into Linux, lspci shows the controller and lsusb shows the devices that are attached to it (with dmesg also confirming the devices that it has seen during bootup). So, it certainly appears that it works under Linux - I have not extensively tested it there though. Unfortunately, one of the cards I purchased did not work at all. Scan are replacing this.

Rated 5 out of 5 by from Exceptional Item was easy to instal in my new pc, works as described very fast transfers. Had to re install drivers several times because windows 10 kept removing it.

Rated 1 out of 5 by from Cannot Get Drivers Working Looks good, specs brilliant however driver issues. They work then they don't, tried to get some advice from SCAN and the web but again get it too work but then after re-boot they don't. It is the USB3 drivers that are the problem. Shame SCAN did not reply to my help emails however kept asking for this review several times. Just using it for the USB2 ports which will always work.

Rated 4 out of 5 by from Only two external ports Look at the text, you will read 4 ports, but look at picture, you will see that two ports are internal/ Now need to find an adapter to get the other two ports out !

Questions & Answers

Why does this card also have a SATA power connector?

Why does this card also have a SATA power connector to the right of the 20-pin connector? Is power to this card needed or will it work without providing power to the card? Surely the power would come straight from the board?
Asked by: aires69uk
Why? Why does this card need additional power and wouldn't just draw power from the board like any other card would?
