Like the 1000W unit, the OCP triggering points are lowly set under cold and hot conditions. The same goes for the over power protection’s triggering points. Nonetheless, the differences between hot and cold temperatures are low, and the 12V rail’s OCP triggering point is a bit higher in hot conditions than in cold ones!

The other protection features are present, including fan failure protection, which is essential!

  1. The difference between the original C1200 and ATX 3.1 version is not just limited to the 12V-2×6 connector. The new version also has one extra PCIe connector, which is good if you have a GPU with three PCIe connectors like the 7900 XTX from AIBs.
