Reports of PSU failures in NVIDIA GeForce RTX 5080 systems have been on the rise. A recent incident involving an ASUS ROG Loki PSU and an RTX 5080 GPU has left owners baffled, but experts point to overheating as a likely cause.
A user reported melting 16-pin power connectors in their system despite running an RTX 5080, with temperatures too high for the connectors’ wires. Similar incidents have been observed with other ROG Loki PSUs, including one that affected an RTX 5090 GPU.
The issue has sparked debate over the quality of wires and connector design, particularly with 12VHPWR cables, which are prone to overheating due to limited headroom for higher power. In contrast, upgrades to 16-pin connectors have not shown similar problems.
As the availability of RTX 5090 GPUs increases, concerns about PSU reliability in these systems will continue to grow.
