did you know that there are 2,000 watt PC power supplies on the market but very
few people seem to be buying them I mean they can offer more watts per dollar
than other high wattage models so why aren't people opting to get something
for nothing let's start by looking at a big reason having a power supply that
powerful might put off consumers namely
it's going to be consuming a relatively large amount of power when the PC is
sitting at or near idle say when doing
light tasks like web browsing this is because power supplies tend to be most
efficient when they're somewhere around 40% load which is 800 watts for a PSU of
this size but a PC near idle might not even be drawing 200 watts and when power
supplies are running at less than 10% of their capacity they tend to be really
inefficient with the result being you're paying more on your power bill than you
would have if you had just bought a lower wattage power supply but if this
is the case why do they even exist well
there are use cases where someone might legitimately need that much power many
2,000 W power supplies are aimed at people who are into cryptocurrency
mining which is very computationally expensive and as such sucks down a lot
of electricity another use case is if you have a very high-powered PC referred
to as a workstation that can be used for 3D modeling or rendering training and
artificial intelligence model or even running scientific simulations for
science some of these machines actually use multiple graphics cards to do all
this Computing which use a lot of power but here's the thing it might be very
difficult to run a 2,000 wat power supply in your home or office at least
if you're in North America even if you could actually use one we'll tell you
why right after we thank Fatam think of your it infrastructure like a complex
puzzle with many interconnected pieces servers applications and networks it can
be challenging to see how all those pieces fit together fatom is an
agentless application Discovery and dependency mapping tool or 0dm for short
with Standalone Discovery and 24/7 application dependency mapping it's
designed to help provide a clear picture of just how your organization's Hardware
software and networks all interact with each other meaning your business can
make changes keep it records and handle migrations with maximum visibility even
better everything can be run offline thanks to the agentless approach meaning
less messing around with every single server you're trying to map out so get

the description a huge part of the problem is that in the US and Canada the
standard voltage for a wall socket is 120 volts if you think back to your high
school physics watts equals volts time amps meaning to power a 2,000 W power
supply when it's at full load You' need almost 17 amps of current but most of
the wiring that's probably in your home or office is only rated for 15 amps
trying to connect a device that needs more amperage than your wiring can
provide will lead to the circuit breaker tripping or even a fire in your walls if
your circuit breaker sucks now some buildings do have 20 amp wiring
connected to certain Outlets these tend to be in places like kitchens so you can
plug in multiple hyraw appliances such as blenders or toaster ovens for example
without tripping the breaker but if you plug your workstation with your 2,000
watt PSU into an outlet like this and leave it running at load for a long
period of time you'd still run the risk of the breaker tripping since they're
often only designed for continuous loads of around 80% which should only be 1760
watts in our hypothetical and plus you'd have to run it in your kitchen which
doesn't sound very convenient so unless you want to pay for an electrician to
come out and install a special circuit just for your beefy power supply because
you truly need that much wattage it doesn't make much sense to try and run
one in a typical North American Home in fact some 2,000 W power supplies are
only designed to work with the 230 volt Outlets used in places like Europe that
don't require as much amperage While others are labeled 1600 Watts when sold
in North America since the PSU will limit its maximum wattage if it detects
it's plugged into a 120 volt outlet and
even a 1600 W power supply would not likely draw a full load since a typical
gaming PC setup even if you're rocking a 4090 wouldn't come close to drawing 1600
Watts additionally multiple Outlets and even entire rooms are often all on the
same circuit so you wouldn't want the PC itself hogging all that amperage
especially as only need to power your monitor your lights your vibrating chair
whatever else you have in your computer room imagine a massage chair anyways

power supply go watch this video next
