00:00:00.040 --> 00:00:06.560
did you know that there are 2,000 watt PC power supplies on the market but very

00:00:04.600 --> 00:00:11.360
few people seem to be buying them I mean they can offer more watts per dollar

00:00:09.120 --> 00:00:14.719
than other high wattage models so why aren't people opting to get something

00:00:13.040 --> 00:00:20.400
for nothing let's start by looking at a big reason having a power supply that

00:00:17.160 --> 00:00:22.080
powerful might put off consumers namely

00:00:20.400 --> 00:00:27.519
it's going to be consuming a relatively large amount of power when the PC is

00:00:24.400 --> 00:00:29.640
sitting at or near idle say when doing

00:00:27.519 --> 00:00:33.239
light tasks like web browsing this is because power supplies tend to be most

00:00:31.439 --> 00:00:39.840
efficient when they're somewhere around 40% load which is 800 watts for a PSU of

00:00:36.920 --> 00:00:44.840
this size but a PC near idle might not even be drawing 200 watts and when power

00:00:42.800 --> 00:00:50.680
supplies are running at less than 10% of their capacity they tend to be really

00:00:48.440 --> 00:00:54.399
inefficient with the result being you're paying more on your power bill than you

00:00:52.520 --> 00:01:00.359
would have if you had just bought a lower wattage power supply but if this

00:00:56.559 --> 00:01:02.879
is the case why do they even exist well

00:01:00.359 --> 00:01:07.720
there are use cases where someone might legitimately need that much power many

00:01:05.840 --> 00:01:11.759
2,000 W power supplies are aimed at people who are into cryptocurrency

00:01:09.799 --> 00:01:16.400
mining which is very computationally expensive and as such sucks down a lot

00:01:14.119 --> 00:01:21.439
of electricity another use case is if you have a very high-powered PC referred

00:01:18.759 --> 00:01:25.000
to as a workstation that can be used for 3D modeling or rendering training and

00:01:23.439 --> 00:01:29.600
artificial intelligence model or even running scientific simulations for

00:01:27.439 --> 00:01:34.200
science some of these machines actually use multiple graphics cards to do all

00:01:31.560 --> 00:01:38.119
this Computing which use a lot of power but here's the thing it might be very

00:01:36.320 --> 00:01:43.479
difficult to run a 2,000 wat power supply in your home or office at least

00:01:41.200 --> 00:01:48.520
if you're in North America even if you could actually use one we'll tell you

00:01:45.600 --> 00:01:52.640
why right after we thank Fatam think of your it infrastructure like a complex

00:01:50.640 --> 00:01:56.840
puzzle with many interconnected pieces servers applications and networks it can

00:01:55.159 --> 00:02:01.280
be challenging to see how all those pieces fit together fatom is an

00:01:59.280 --> 00:02:06.840
agentless application Discovery and dependency mapping tool or 0dm for short

00:02:04.719 --> 00:02:11.120
with Standalone Discovery and 24/7 application dependency mapping it's

00:02:09.160 --> 00:02:15.280
designed to help provide a clear picture of just how your organization's Hardware

00:02:13.040 --> 00:02:19.680
software and networks all interact with each other meaning your business can

00:02:17.120 --> 00:02:23.959
make changes keep it records and handle migrations with maximum visibility even

00:02:22.239 --> 00:02:27.440
better everything can be run offline thanks to the agentless approach meaning

00:02:26.000 --> 00:02:30.879
less messing around with every single server you're trying to map out so get

00:02:33.120 --> 00:02:39.239
the description a huge part of the problem is that in the US and Canada the

00:02:37.200 --> 00:02:44.720
standard voltage for a wall socket is 120 volts if you think back to your high

00:02:41.840 --> 00:02:49.800
school physics watts equals volts time amps meaning to power a 2,000 W power

00:02:47.680 --> 00:02:55.239
supply when it's at full load You' need almost 17 amps of current but most of

00:02:53.599 --> 00:03:00.239
the wiring that's probably in your home or office is only rated for 15 amps

00:02:58.720 --> 00:03:04.040
trying to connect a device that needs more amperage than your wiring can

00:03:02.239 --> 00:03:08.840
provide will lead to the circuit breaker tripping or even a fire in your walls if

00:03:06.360 --> 00:03:13.239
your circuit breaker sucks now some buildings do have 20 amp wiring

00:03:11.239 --> 00:03:17.319
connected to certain Outlets these tend to be in places like kitchens so you can

00:03:15.159 --> 00:03:21.879
plug in multiple hyraw appliances such as blenders or toaster ovens for example

00:03:19.440 --> 00:03:26.280
without tripping the breaker but if you plug your workstation with your 2,000

00:03:23.720 --> 00:03:30.439
watt PSU into an outlet like this and leave it running at load for a long

00:03:28.280 --> 00:03:34.720
period of time you'd still run the risk of the breaker tripping since they're

00:03:32.519 --> 00:03:41.360
often only designed for continuous loads of around 80% which should only be 1760

00:03:38.599 --> 00:03:45.200
watts in our hypothetical and plus you'd have to run it in your kitchen which

00:03:43.080 --> 00:03:48.799
doesn't sound very convenient so unless you want to pay for an electrician to

00:03:46.920 --> 00:03:52.599
come out and install a special circuit just for your beefy power supply because

00:03:50.519 --> 00:03:57.159
you truly need that much wattage it doesn't make much sense to try and run

00:03:54.760 --> 00:04:02.200
one in a typical North American Home in fact some 2,000 W power supplies are

00:03:59.360 --> 00:04:06.519
only designed to work with the 230 volt Outlets used in places like Europe that

00:04:04.480 --> 00:04:11.200
don't require as much amperage While others are labeled 1600 Watts when sold

00:04:09.400 --> 00:04:17.199
in North America since the PSU will limit its maximum wattage if it detects

00:04:13.680 --> 00:04:19.880
it's plugged into a 120 volt outlet and

00:04:17.199 --> 00:04:24.320
even a 1600 W power supply would not likely draw a full load since a typical

00:04:21.959 --> 00:04:30.080
gaming PC setup even if you're rocking a 4090 wouldn't come close to drawing 1600

00:04:27.240 --> 00:04:34.759
Watts additionally multiple Outlets and even entire rooms are often all on the

00:04:32.520 --> 00:04:38.840
same circuit so you wouldn't want the PC itself hogging all that amperage

00:04:37.120 --> 00:04:43.000
especially as only need to power your monitor your lights your vibrating chair

00:04:41.759 --> 00:04:47.720
whatever else you have in your computer room imagine a massage chair anyways
