History of Computer Power Supplies

Power supplies are often an easily-forgotten component of a computer build, but they’ve actually changed quite a bit over the years.

A challenge for Techquickie
Explain how VRM’s work.

Pensive says:

I have it pretty simple today

Julius Zietlow says:

I think i shold keep the power supply of an old pc i have laying around. it has atx cables but is triangular. they had to do this to fit it into these small under-monitor-cases which had a dvd drive which were really fat in these times.

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.

in a PSU important to be 80+ certified, dont go cheap. You can get a 650w cheap PSU and after a while you realise on 12v rail only gets to 400w instead of 600 that you need, thats why 80+ certified no cheap and make shure 12 rail is at least 600w.

This guy looks eerily similar to the Linus from LTT… Is it just me that noticed this?

SimonTekConley says:

Have you not worked on a Dell, or Lenovo recently? Not standard on Power supply

L8zin says:

2:46 Lmao look at the background

Shockszzbyyous says:

the amount of electricity is the Voltage, and the Current is the strength of the push. …. or am i completely wrong here ?

antoine morfos says:

Did anyone nottice the apple logo on 2:50?????

Panduka Rathnaweera says:

Anyone else noticed the Apple logo in the background during “proprietaryville”? Ouch.

UrDaddy WingNut says:

2:30– Zoink Zoink

renjith ps says:

Alternative for this snps or atx can convert to this dps-320nb-1a?

numb3r6 says:

I am using my BFG 1200 watt PSU i bought almost 10 years ago and its been on almost 10 years….Sadly the companies out of business and I think it also so uses a Technology that isn’t in anything else that I’m aware of.

kilgarragh says:

i have a nice gpu, no external power works with my mini tower becuse of low profile bracket it cant run vr tho

SirNapkin1334 says:

Uhhh…my PSU only has an on and an off….

Murad Beybalaev says:

You just had to play with his eyebrow.

The history of computer reviews

Andrew Leonard says:

2:47 I see what you did there 😉

Andrew Dupuis says:

now days people are using away to much power

Cain Kamikazi says:

what the hell… did Linus borrow Satan’s Forehead?

Nice apple shadow

That wont explode when you run crysis. Shots fired at RandomGaminginHD before it even happened.

Jed ITS says:

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.

Jeremiah L says:

5:00 Please god don’t call it a “voltage regulator module” it is just a voltage regulator, there are types of voltage regulators, the most used in motherboards is a buck converter (extremely efficient, but complex type of voltage regulator that lowers the voltage by turning the output on and off repetively, then stores the power in a capacitor to smooth it), linear voltage regulators (which is very inefficient because they convert the remaining voltage to heat so if you have 10V at 1A [10W] coming in and you regulate it to 5V at 1A [5W] the other 5W is loss as heat), and boost converters which step the voltage up (eg. 3.7V to 5V, common in phones; like buck converters they are extremely efficient, but complex type of voltage regulator that raises the voltage by shorting out an inductor creating a voltage spike, then stores that in a capacitor and smooths it)

What about the *80 Plus Stalinium* grade power supplies!? IT’S IMPORTANT COMRADE!

S.N. Khamokariya says:

Nice video

jasa_m says:

Forced 20 second add before the video? Addblock on.

Hey It's J says:

Do “80 Plus Certifications as Fast As Possible”

Nmotsch idontwannagivemyrealname says:

Aren’t ATX PSUs compatible with BTX mobos? Why would they make a BTX standard for PSUs?
