00:00:00.080 --> 00:00:06.759
if you're a seasoned PC Builder or tinkerer you can probably rattle off a

00:00:04.440 --> 00:00:11.480
few different connectors and headers on your motherboard in your freaking sleep

00:00:09.360 --> 00:00:17.039
especially if you dream about RGB heat sinks like I do but what about all those

00:00:14.320 --> 00:00:22.400
other little tiny components for instance the capacitors and resistors

00:00:19.720 --> 00:00:27.519
that fill up all the extra space what exactly do they do well a big part of

00:00:25.080 --> 00:00:32.360
the reason you have so many electronic components on your motherboard's PCB is

00:00:30.279 --> 00:00:38.440
that your computer parts like CPU graphics card memory Etc typically can't

00:00:35.640 --> 00:00:43.280
use electricity directly from your power supply for example most of those 650

00:00:41.879 --> 00:00:49.120
Watts or whatever your power supply promises are delivered on the 12vt rail

00:00:47.000 --> 00:00:55.399
but imagine what would happen if you put 12 volts through a modern CPU which only

00:00:52.039 --> 00:00:58.120
needs like a tenth of that to run you'd

00:00:55.399 --> 00:01:04.680
fry it faster than an egg on a hot radi uh sidewalk so because everything in

00:01:01.359 --> 00:01:07.040
your PC needs a very specific amount of

00:01:04.680 --> 00:01:11.759
power your board has lots of capacitors on it those are the cylindrical looking

00:01:09.400 --> 00:01:17.280
things that poke out of your motherboard like little tiny water towers in a

00:01:13.799 --> 00:01:19.159
little miniature City H they even serve

00:01:17.280 --> 00:01:25.079
a somewhat similar function to the aformentioned water towers they store

00:01:22.000 --> 00:01:27.119
energy then release it in a controlled

00:01:25.079 --> 00:01:32.880
fashion you see the power that comes into them doesn't flow completely smooth

00:01:30.079 --> 00:01:37.799
ly and has small variances in voltage that could make it useless or even

00:01:35.600 --> 00:01:42.560
damage your components so these small capacitors clean up the power and

00:01:40.320 --> 00:01:47.439
deliver the silky smooth constant voltage that your internal Electronics

00:01:44.600 --> 00:01:53.360
need and if you open up a decent power supply make sure it's unplugged first

00:01:50.759 --> 00:01:58.159
you'll probably find some much larger capacitors that serve a similar function

00:01:55.920 --> 00:02:03.280
keeping a constant DC voltage for your computer and filtering out no noisy AC

00:02:00.840 --> 00:02:08.319
interference also called Ripple but although capacitors help to clean up the

00:02:05.479 --> 00:02:12.720
power resistors do much of the heavy lifting when it comes to controlling

00:02:10.599 --> 00:02:18.440
what voltages your components actually get as you can probably guess a resistor

00:02:15.959 --> 00:02:23.360
resists the flow of current ensuring that your components won't get so much

00:02:21.040 --> 00:02:27.360
power that they'll be damaged although many hobbyist who have worked with

00:02:24.760 --> 00:02:32.040
simple circuits might be familiar with resistors that look like this with

00:02:30.080 --> 00:02:37.599
colored bands that indicate strength measured in ohms most resistors on

00:02:34.480 --> 00:02:40.440
Modern motherboards are more understated

00:02:37.599 --> 00:02:45.680
in appearance looking like little black and silver rectangles okay then but what

00:02:43.400 --> 00:02:51.280
about all those blocky things near my CPU they don't look like capacitors or

00:02:48.480 --> 00:02:55.519
resistors and okay well you'd be right these are called chokes which and okay

00:02:53.640 --> 00:03:00.640
don't get too excited they're a type of inductor similar to how a capacitor will

00:02:58.080 --> 00:03:05.840
smooth out voltage and an inductor will smooth out current important considering

00:03:03.319 --> 00:03:11.560
how much power a typical desktop CPU can draw you can learn more about CPU power

00:03:08.799 --> 00:03:15.680
delivery right up here and speaking of power delivery we would be remiss if we

00:03:13.760 --> 00:03:20.760
didn't mention our old friend the transistor you might know that there are

00:03:18.280 --> 00:03:26.159
millions or even billions of tiny transistors in your CPU and chipset that

00:03:23.920 --> 00:03:31.080
act as logic switches that allow your computer to function but there are

00:03:28.560 --> 00:03:36.280
larger ones on on your motherboard close to the chokes that I mentioned earlier

00:03:33.640 --> 00:03:41.959
called mosfets since transistors can both change voltages and have logic

00:03:38.720 --> 00:03:44.000
gates your mosfets and CPU actually talk

00:03:41.959 --> 00:03:49.200
with each other to figure out the correct amount of voltage to deliver to

00:03:46.000 --> 00:03:51.720
the CPU at any given time then the

00:03:49.200 --> 00:03:56.760
mosfets take the electricity from your power supply adjust the voltage and pass

00:03:54.519 --> 00:04:00.920
it through the chokes and onto your processor so obviously the engineering

00:03:59.079 --> 00:04:06.560
that goes into making all of these parts work together properly is quite complex

00:04:04.159 --> 00:04:11.519
but hopefully now you have a better idea of why all those random bits on your

00:04:08.519 --> 00:04:13.439
motherboard are even there and if not

00:04:11.519 --> 00:04:19.759
you could always just buy one of those new fangled boards with the nice looking

00:04:16.440 --> 00:04:22.600
shroud and RGB lights and forget

00:04:19.759 --> 00:04:28.880
everything that I just said it's not like you'll hurt John's feelings or

00:04:25.560 --> 00:04:30.320
