I just got a new power supply unit (PSU) for my PC build, and it came with a C19 connector. Usually, in the UK, PSUs are supplied with C13 connectors, often referred to as 'kettle leads' since old kettles used them. I'm curious if this is a new trend with PSUs. Has anyone else come across this kind of connector in recent purchases?

PSUs are now made to work across different markets, and with US grids typically at 115VAC, the 10A limit of C13 is reached at around 1150W. In regions with higher voltage, like Australia, it's conceivable to run a 2000W PSU on a C13, but it would be risky. If you're not concerned about the size, that's fine, but it's definitely a trend with higher watt PSUs!
C13 is your standard low wattage cable, while C19 is meant for higher wattage setups to avoid mishaps with incorrect connections. What's the wattage on your PSU? That determines the type of connector you'll need. It's generally 1200W or higher that requires the C19.
If it's 1200W, then that's good. Just make sure you’re using the correct fuse on the other end!
The C19 connectors are designed for high power applications, allowing up to 16A. In comparison, C13 connectors are limited to a max of 10A, which is about 2300W at 230V. If your PSU is pushing around 1000W or more, it makes sense they included a C19 to ensure safety across different voltage systems.
Most big PSUs, especially those rated 1600W or more, tend to use C19 connectors nowadays. Even some 1200W models might also include them. If you've gotten such a high-watt PSU, this is fairly normal now.
Yep, it’s a 1200W unit I bought this time. It’s interesting how power needs are growing for GPUs and CPUs!
I appreciate the insights! I’m just fascinated by how much power modern hardware can handle.
