[Question] Will USB Type C replace Power Supplies?

post #1 of 3
Thread Starter 
I've been looking into the smallest possible solution, it made me thing about the powers of USB Type C, apparently capable of delivering 100W.

With processor becoming more energy efficient and iGPU becoming more powerful, will desktops eventually bail on power supplies in favor for USB-C in the future?

I believe the purpose of the PSU is to convert from AC to DC. You can't just plug in a USB C cable to the motherboard from the wall. Besides, components don't need all the extra features of a USB C interface. They just need power.

No it won't unless it's a tablet or low power laptop. Components may become energy efficient but that doesn't mean they consume less power. Energy efficient means performance per Watt goes up, not the wattage goes down, unless you mean ULV chips found in fanless tablets and laptops. So, while chips are extremely efficient compared with what was available 10 years ago they consumer magnitudes more power simply because they are more powerful.
