MSI's upcoming X870 motherboards can draw 252W from the PSU via a new power connector, allowing it to deliver up to 165W to its PCIe slots.

I'm really curious what the point of this actually is in the real world. The same specifications mandate excursion protection within the PSU which means you shouldn't see them through the slot as it'd already be covered through PCIe power. I sure hope this isn't an indicator of things to come in the video card space.

36w for RGB can light a whole small house...

I don't want to hear what 132W of fans sound like. But I imaging something like when a rack full of servers kicks in. Not something I want to sit next to.

And why do we need another F'n 8-pin power connector with different pinouts from the already different CPU and GPU connectors? They all need to supply the same 12V power. This is getting stupid.

Only 8 years after a certain infamous AMD GPU that pulled over 75w from the PCIe slot...

Well let's hope that 420w will be... High... Enough for everything.

36w of RGB is the PC equivalent of those trucks with a wall of LED off road lights on the front...

This should have happened LONG before now. It's been well-known that GPUs are power-hungry since forever, and yet, we've been using the janky workaround of connecting external power cables to compensate for the lack of power on the PCIe slot for just as long. More power-delivery should have been included in the next PCIe revision back in the mid 2000s.

This doesn't help there at all as the PCIe spec is still limited to 75W sustained from the slot.
