Reliable enough for a small 6-8 card rig with plenty of space between GPUs - all mine run at reduced voltage and don't need additional fans for cooling. So far, a combination of 3070, 2x 1080Ti, 2x 1660S and 1660Ti has been used. However, I switch to 6x RX 570 so that I don't need a second power supply to the side.
