Poor QA, PC only boots without it plugged in. Fails to work.
Mine did not work. The PC would not boot with it plugged in. The SATA power port and PCI-E x16 Slots were very loose. I believe the soldering job was poor and losing contact. Wasted $45. I wouldn't recommend this product.

Perfect. Does exactly what I need
Pcie 4 bifurcation works.Easy to install and use.

Doesn't work as intended
Does not split - passes all the data through to a single card.

Worked for running 2 3090s in 8x8x bifrication
Gen4 speeds even with risers attached. Works great!
User
Shorted entire PC upon powering on
Configured motherboard for x8x8 bifurcation on the x16 slot.Plugged one GPU into expansion card to test.Seconds after powering on PC the card shorted and the PC shutdown.PC fails to post. Incredibly expensive mistake
