Apple isn't the only thing that's proprietary. Sure it's proprietary at the hardware level, but Windows is just as bad as Apple as far as software, if not worse. Just look at secure boot, Microsoft's attempt at locking people into only using their operating system by putting a password on the bios that only Windows can unlock, making devices defective by design.

[@fearmemortals]

Haha that subliminal messaging

[@shooterboss]

That's a good point, but at the same time Apple is also trying to lock people into their software ecosystem. Mobile app development for iOS, for instance, must be done on a Mac device, and the App Store will ban you if you try using a virtual machine to get around that restriction. Also, Apple ensures that no other manufacturer can legally sell a PC with their operating system installed.

[@tacokoneko]

3:34 BTX power supplies are actually fully compatible with ATX standard, at least externally and, as far as my experience goes, electrically; any BTX case will fit an ATX power supply, albeit usually only in the prebuilt/old-fashioned orientation at the top of the case, and vice versa. The connectors are also the same. I do know the Dell at least, while manufacturing prebuilts to the BTX standard, did sometimes put their own spin on it by having a locking clip of sorts at the top of the case and a corresponding slot on their power supplies. This would make ATX power supplies fit somewhat awkwardly, and the clip would press against the top of it and leave scratches and dents. Besides this, though, as far as I am aware there was never any substantial difference.

[@metalheadmalta]

[@vyor8837]

The long and short of it is that the "I" in IPC is essentially how many calculators you can use at once. So you have 2 hands, that's two calculators. So that's 2 instructions you can do at once. The "PC" part is "per clock," 1 megahertz is 1 million cycles in a second, 1 gigahertz is 1 billion cycles in a second. So if you run at, say 1 hertz(aka, 1 cycle a second), you could do 2 calculations a second with your calculators. If you ran at 1 megahertz you could do 2 *million* calculations in a second. Modern processors can do a lot more than 2 calculations every clock cycle of course, but there you go.

[@ganaraminukshuk0]

Voltage (there's no -age equivalent): the amount of "oomph" each charge has Current or amperage: the amount of charge going through a particular point in a wire per second Power or wattage: how much "oomph" is being delivered or used per second, calculated as voltage times current Therefore, 10 watts could be either 10V * 1A or 1V * 10A.

Been building PCs since 1993 and still build retro rigs - Aside from some minor connection differences (single mains vs "black to black" multimain), the ATX standard varies a lot more, with many aux pins here and there, indeed even 20 pin to 24 pin variants. There was no such variety with AT.

You can still buy AT power supplies brand new. They're used in a lot industrial automation stuff, which means they're still needed by businesses for various purposes. Side effect? You can still buy them. Worth knowing if you are into retro computing. (the one I came across was a 300 watt brand new AT power supply - more than enough for nearly any system that could even make use of one... The internal construction may well be closer to modern power supplies, but that really doesn't matter...)

Now I use an Intel NUC computer that is a third the size of an ATX power supply and it runs from a wall wart that looks like about a 30W power supply. I would look but I would have to unplug it, reboot, find this web site again. You know the drill. The bigger NUCs with more cores use a 65W power brick. Mine is the thinner one and is not even as big as the early 5" hard drives. It is so small I have to use an external gigabit USB router which is almost as big as the entire computer to get all the USB ports I want. I guess this it getting close to the end of the road for the TL494 chip they used in all the previous PC power supplies.

Future power supplies should learn a lesson from the AT power supplies with their long-throw hard on/off toggle switches. Old rigs from 1984-1996 lacked the 5V standby rail and the toggle switch is before the bridge rectifier, consuming no power while turned off. My idea for future power buttons is a mix of old and new, with the short-throw acting like any ATX power button, used for waking the machine up and commanding the OS to shut down. This new hybrid power button design features a long-throw toggle switch located before the bridge rectifier on the PSU's circuit schematic. When you shut down your machine with the hybrid power button, the toggle switch is automatically toggled off to eliminate standby power consumption.

Yeah, I've AT PCs and : - All of them have the same pinout - All of the PSUs are the same size I've never seen an AT PSU with a different form factor. Not that they don't exist but if they do, they must be very rare

[@alexatkin]

Exactly, AT IS a standard, just as ATX is another. Heck, ATX PSUs aren't as simple as made out here as there are many generations/revisions when it comes to how the voltage lines are designed to be loaded. During the early Athlon years there were problems with PSUs dying because Intel had moved the CPU regulators onto the 12V line and ATX was revised around that, but Athlon still relied on the 5V. It wasn't always immediately obvious which version of PSU you were buying so you could end up overloading the 5V lines, which at the time most PSUs had poor or no overload protection so would just fry.

[@losttownstreet3409]

In the early AT world where soldering skills pretty much standard: older motherboards had sockets and emtpy location where you could upgrade your SRAM, DRAM, .... Now you had a 6-10 Layer motherboard with 0204 Chips. SOP's are now the bigger Chips. With AT the design was one PSU and not many regulators on the Motherboard. Now you didn't use one big flyback but many buck and boost converters on the motherbords and in the processors itself. Try now to build a low grade motherboard and you are getting in a lot of power delivery problems you had to solve. Back in the AT-world you connect the right rail from the PSU.

[@nqh4393]

Power supplies are just power converter. I've been lied to my whole life.

[@chessprince1164]

The AT-Standard we can find also in Industrial Computers today

[@harshbarj]

AT power supplies did in fact have a standard. The most common was the ones that used the P8/P9 connector. Most AT boards you bought on the market would used this standard. Only some OEM systems decided to used a different connector. Much like in the early days of ATX, companies like DELL would use ATX like power supplies that were not really ATX.
