be quiet! BC072 12VHPWR Adapter Cable for Dark Power Pro 12 / Dark Power 12 / Straight Power 11 / Pure Power 11 FM, for RTX 4090 and RTX 4080.

Using it to power my RTX 4090 and the case is a lot cleaner without having the ugly adapter into four 8-pin cables! fits neatly into Straight Power 11. Make sure you read the instructions for your power supply to make sure you're using the right rails! These PSUs have 2 rails and you should split the load.

Works great with 4090 and dark power pro 12 psu.

Almost a month later and everything remains unmelted. Would have been nice if the cable length was longer though to snake the cable up from the bottom but no big deal for me.

Great cable. My rtx 4090 needed 3 discreet 2x8pin cables created a bird's nest of cables. This single cable designed for my BeQuiet Silent Pro 12 power supply worked perfectly and delivered 600W to my card.

This adapter saves so much room in my case. It cleaned up the rat's nest of cables in front of my power supply.

The plastic retention clip snapped off when minimal pressure was applied, not sure if a defect from the factory or if the design itself is the problem (see pictures). This happened about 3 weeks outside the return period, I sent a message through Amazon for assistance and was told to contact the manufacturer directly. Just adding I have been building computers since the 90s, and I have NEVER had a retention clip break besides this, it makes me call into question the quality of my Dark Power Pro 12 now.

Held out and finally got a 4090. Didn’t want to use the provided adapter with the card. This plug allows for one simple plug straight from card to power supply. Perfect length as well. Quality seems really good as well.
