We previously reported that the 12-pin PCIe Gen 5 connector for the ASUS power supply was fully compatible with the NVIDIA GeForce RTX 30 Founders Edition graphics cards. However, upon further investigation, the PCIe Gen5 connector for the ASUS Thor power supply cannot produce the full 600W of power as per the standard requirements.

There is a caveat with the designs of both the PCIe 5.0 12-pin and 12+4-pin variants. The second mentioned version is an entire specifications power supply cable that presents twelve pins parallel to four data signal paths. The four additional pins are essential for full compliance with PCI-SIG standards, "12VHPWR High Power Connector (H+)," which is considered the new premium power connector to supply future graphics cards.
