That is the plastic melting. It is 4 wires, not one, but they may not be able to handle it well. As I said, the 150 W limit is simply a (probably PCIe) specification (6-pin connector only has 2 +12 V wires*, so 75 W limit for that makes sense), and the 529 W is the connector limit.

* The PCIe/ATX (whichever is appropriate) specification for the 6-pin connector has 3 ground and 2 +12 V connectors. Most PSUs have 3 +12 V wires, but most cards only use 2.

If they want to assume PCI-E 1.0 backwards compatability, then 375 watts is the most if they wish to remain in specification. PCI-E 1.0 supplies 75 watts through the slot itself, and two 8-pin connectors is another 300 watts.

If they bump this up to PCI-E 2.0 requirement, they have 450 watts to remain within spec (150 watts from the slot, and two 8-pin connectors for an additional 300 watts).
