C13 Power Cable vs C19: What's the Difference?

Depending on what PSU you have, there's a chance you've noticed your PSU's AC power cable is different from other PSUs'. As pictured below, you'll see a distinct difference between the two.

Select PSUs, specifically higher wattage ones, use C19 due to power draw. The more common C13 connectors are normally rated for a maximum of 10 amps (@ 250V), while C19 connectors are normally rated to handle 15 amps (@ 250V).

If you compare the two physical designs alone, you can tell the C19 connector is more robust as it is designed to handle the larger power draw. Even the power cable itself is typically thicker due to requiring a larger gauge of internal wiring.

For our PSUs that are rated 1500W and above, such as the HX1500i and AX1600i, they will use the C19 power connector. Otherwise, our PSUs are designed and strenuously tested with the C13 connector, so there's no need to fret if you see otherwise.
