Review on Upgraded VER009S PCIE Riser Express Cable 1X to 16X with Dual-6pin / MOLEX Connectors, LED Graphics Extension for Efficient Ethereum ETH Mining - Powered PCI-E Riser Adapter Card, 6 Pack - includes 24-inch USB 3.0 Cable by Kahyin Hawkins

I bought these adapters on purpose because I didn't want to use adapters or splitters to power the cards and they were for the amount I needed (plus a few backups) cheapest in case of failure.) First off, I'm impressed that none of them were DOA; The first four I opened worked immediately. The extra Molex connector was perfect for my build, and I was able to power everything from the two PSUs I had instead of upgrading to a 220-watt server PSU or a pricier (and more expensive) modular PSU. What I don't like are the performance indicators. I'm not a big fan of LEDs on my devices, let alone the ones that stay on all the time. They'll probably help with diagnostics in the event of an error, but they're absurdly smart.
