Linus takes a look at an ATX 12V0 PSU

I don't think a single move to a solitary 24v psu is really plausible. It would need new GPUs that run at 24v (and other add in cards of course, but GPUs are the obvious and most power hungry ones), unless you expect the motherboard to include the step down components necessary to power GPUs which in some cases you're look at north of 700w of 24>12v stepdown (to support the majority of dual GPU configs), which is more than your average ATX psu can output. That's bad for a number of reasons, cost being one of them.

A split 12/24v psu could work. But then how much capacity do they throw at 24v considering there's exactly no hardware output there that supports it right now? It's a bit of a chicken and egg situation.

If 12V0 gains traction, i can see revisions being made or new standards being born of the back of this - remember 12V0 is only aimed at system integrators right now - so maybe down the line 24v could be adopted as part of a new generation of ATX PSUs. But, even if that happens, it would be likely years before we see them on the market.
