I wanted to add, I ordered and received 2 riser cables.
They appear to work just fine, just the white clip is a little flaky, I bent mine trying to get it back on. ( I don't blame the manufacture, just the ol' adage, don't force it or it will break)
Delivery took a little faster than expected, seeing how it was coming from UK to South Central Region, PA, USA.
I do like how they look well made and have a decent molex adapter and wires, I didn't even see the capacitor thing on other cables like this.
Other than the white clip, the only issue was I forgot to hook up the power cables to the hanging cards
I guess I was a little excited to get them in place, so I focused on the cable and not the power, except the molex connector.
FWIW: ~ $40.00 for 2 including shipping for those who are wondering what the cost was total.
Dumb Question: Can I use them in a 4x full length slot?
