Countries like Australia/China 240v is the standard. You need step-down transformers for 110v devices. China has both voltages/plugs running in its cities - not sure how they manage that.
- mkl 4y agoMost of the world is on 220-240V: https://theverbalized.com/why-do-we-have-two-standards-of-electricity-supply/ https://theverbalized.com/why-do-we-have-two-standards-of-el... Also the power supply to a GPU is DC anyway, so the wall voltage probably doesn't matter much.
- sgjohnson 4y agoThe United States is also a 240V country. It’s just split phase. But yes, mains at the wall would be 120V.
- Covzire 4y agoA common misconception about the US is that the US is only 110V. 220V service in homes in America is standard, it's just that standard power plugs around the house get 110V because of split phase breaker boxes. This lets 220V be available for large appliances like Washers, Dryers etc using the full phases, and 110-120V to the rest of the house using only half phase. In my next house, I think I'll request a 220V outlet in my kitchen with a UK style plug, so I can have my fast tea kettle.
- onethought 4y agoDoesn't seem like a misconception. It seems like y'all have 110v power outlets. Having 220-240v somewhere else is kind of moot... The power socket IS the interface, so if the interface is 110v, then the switcher box, the power line, the high voltage power line, the power plants voltage aren't really relevant.
- onethought 4y agoHow can that be true? I plug a kettle cable from my a/c socket to the GPU... is there a rectifier involved in a standard PC setup?
- mkl 4y agoYou plug the AC cable into the PC's power supply, right? That converts to 5V and 12V DC and feeds it to the GPU internally. There's no way to plug external power directly into the GPU.
