Intel is changing the future of power supplies with its ATX12VO spec

Four important things to consider: First, this already happened to some extent. Outside of drives and fans, the virtually all of the power used in your system is exclusively 12v; either from the 12v pins on your ATX24 or P4 or EPS12 connectors, or via the PCI-E connectors; very little non-drive or non-fan power is supplied via 3.3 or 5v rails. Second, almost all PSUs today use 12v DC to 3.3/5v DC converters to increa…

10-gauge is rated for 30A, though that's 3.6mm.

Actually the limiting factor is the amperage rating of the molex terminals ("pins") that make the physical contact. I have expertise in this area back from the days of Bitcoin GPU mining where I built custom cables that I crimped myself after buying the molex housings, molex terminals, and wire. Each individual terminal, formally called a Molex mini-fit junior terminal, is rated either 7.0A (typical for those with 2…

I agree it's delusional, but to give some hard data, Mercury Research published its quarterly findings on x86 market share as of Q4 2019[0]. Specifically: - On the server side, AMD market share is only 4.5% (up by 1.4 percentage point from last year) - For desktop, market share is 18.3%, up by 2.4 pp from last year. - For laptop, market share is 16.2%, up by 4.0 pp from last year. - For overall x86 chips, market shar…

> Maybe in 4-5 years, AMD will be the dominant player. But it's still too early to call them this. Highly unlikely. This is AMD's prime time because Intel screwed up, and they've peaked at 15%. I predict Intel to gain the pace in a few years and dominate the market once again.

If your goal is to game or work during a power outage, sure. If your goal is just to protect your data from sudden termination, then having a PSU with a built in UPS is quite nice.

Being able to power any external device (like a hard drive) or to be able to cleanly exit from whatever you're working on if you happen to be present (with a monitor) are both pursuant to these goals. The average PC or workstation isn't configured for a clean exit just because the UPS said it's time. Bridging momentary outages is also useful where that's common, disregarding data loss.

They ought to be able to exit cleanly in time... that's what hibernation is for.
