This reminds of those dark ages when Half life 1 was new and a friend of mine got a weird shady, cheap power supply despite everyone telling him not to. Moments later smoke was rising from his tower. Good times.
I used to work for a company that serviced camera surveillance PC's, and they would always order the cheapest PSUs they could purchase or even salvage, leading to many fireworks displays and fried motherboards. Don't save pennies on PSUs folks.
I still use my 700 watt psu since I bought it new back in 2007. Tagan Dual Engine TG700-U25. Built like a tank, well made, it's heavy, has dual 80mm fans and +12V@56A(4 Rails together). Costed around 1500 SEK at the time ~ 150 euros or 160 usd. This PSU doesn't show any sign of giving up anytime soon.
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.
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.
+Ryan Mattox why do you think we've all started to hate Microsoft increasingly more? Given how ubiquitous it is though, it's a necessary evil nowadays.
As a PCB designer and electronics technician myself with loads of years of experience, I can tell that you have done some good research, although there is much more once can say. But very good job... thumbs up.
I have an IBM-PC 5150. What I found most surprising is that the same exact power cable can be shared between it and my current desktop rig. That must have made at least something easier over the years! :)
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.
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.
I remember changing some of those old at and pre at power supplies. Sometimes you could wind up way down a rabbit hole depending on some of the craps soldered onto the bleeding thing.
We have a HP PC that we wanted to upgrade which also meant using a new case. Not only was the CPU cooler mounted on the case itself but it had a built-in proprietary PSU with very different cables. Even though we supposedly worked the pins out and used the original PSU for a few cables it still didn't boot.
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.
I overdid it with my PSU. I ebay - sourced an unused open-box 750 Watt 80+ Platinum for my home server, plugged it up, and was very pleased by the noise level. Then I hooked up the system to the UPS and queried the UPS and the UPS said "ya, you're drawin' 47 Watts at the wall dude". Well... at least its efficient.
Forgot to mention Flex ATX. It's another ATX derivative, even smaller than SFX and flatter, recently gaining popularity in ultrasmall form factor builds.
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. Please let me be not the only one who understands this...
deggial2005 It's always been there. It's a design defect that cannot be predicted, hardware companies need to redesign those PSU when it happens. Reviews are here to help us with that.
Linus, do a video on the differences of single +12V rail and 2 +12V rails/multi +12Vrails. If I remember right I think the single +12V rail is the best, from what I remember back when building my rig.
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.
To the tech quickie video editor: Please stop showing illustrations of what he's talking about BEFORE he talks about it, its basically adding subtitles that are ahead of the video, it does not work well.
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...)
Ty for bringing up the old 20 pin pcs connector. I rememver when the connector vegan to shift in this direction some psus had 20 and others had 20 with a 4 pin addapter to support the newer pcbs at that time. I had to run out and buy a replacment one time because my old psu was a 20 pin
I remember having and using at school old ibm beige boxes that ran dos and had a hard on off switch and a printer with a long ream of perforated folded paper with tear away edges.
SFX/SF or small form factor power supplies are not irrelevant! A growing number of consumers actually like the mini-ITX profile cases and would prefer to utilize more of the precious little realestate for motherboard components and/or cooling rather than have a power supply hog all the space.
I've gone through a few Antec power supplies in the past. The power supply would just simply die or almost cause the ATX plug to get stuck in the board because it would fry a little...
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
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.
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.
Hey Linus, USB Power Delivery supports up to 100 watts, so why can't we have a new power-supply with slimmer cabling/connectors? That ATX 24 often makes slimmer cases hard to close...
This reminds of those dark ages when Half life 1 was new and a friend of mine got a weird shady, cheap power supply despite everyone telling him not to. Moments later smoke was rising from his tower. Good times.

Similar thing happened to a friend of mine around the same period as well. It was a Q-Tec, IIRC.
