we're here at cooler Masters booth at CES 2024 and the amount of engineering
prowess that they have on display here is not what I was expecting at all their
new X series of power supplies are just
mind bogglingly cool this thing right here 1,00 watts and completely fanless
look at this absolutely silent and if
you put a fan on it it can go up to
2800 watts of course you can't do in North America your Breakers would just
blow but if you're in Europe you absolutely can this thing is actually
Bonkers now there's two things that you need to have a fanless power supply
first of all you just need cooling Cooler Master can do that that's not too
hard and also it needs to just be incredibly efficient which is the
particularly difficult part although first let's just have a little talk
about the cooling the first way to dissipate heat is pretty simple you
stick a big old heat sink on top of your components and uh yeah that just gets
the heat away but they've gone one step further than that and the whole bottom
of this power supply case is one great big heat sink so your main Transformer
that goes from your 400 volt down to 12 is right over top of this coal plate and
they have four heat pipes that are going to take that heat and spread it all
across this extruded piece of aluminum right here this cooling solution is
pretty sick but when we look at the actual way they've got the efficiency so
great in this it is incredible just like this incredible segue to our sponsor
thanks to be quiet! for sponsoring our CES 2024 coverage if you're shopping for
your next PC build or just new components in general make sure to check
out be quiet! their premium products include PC cases power supplies Water
and Air Cooling and fans for desktop PCS
with roots in Germany they've been in the industry for more than 20 years and
specialize in making high quality parts that are nearly inaudible this year at
CES they're showcasing their new white PC cas as white fans and even white hard
drive cages step into the world of Silent Computing with be quiet! at the
link Down Below in the past though we have seen fanless power supplies but
they've capped out around 750 watts and
how Cooler Master was able to take this up to that 1100 was with the components
in here so let's go from the wall to your computer and show you it compared
to just sort of like a normal quite high-end power supply the first bit of
your power supply is your dirty wall power comes in right here and needs to
be cleaned up by your power factor correction now if this is not done
properly your voltage and your current might be a little bit out of phase or
the noise that's coming from your wall will cause that to be out of phase and
it can be very inefficient now in a normal power supply you might have your
medium flux chokes and those are pretty good but it's not like they're very
fancy high flux chokes that they've got in this one the main thing is just that
the materials are quite expensive in these ones right here and it makes them
able to really really get that noise down the next step is to take your AC
input and change it over to DC using a bridge diode Well normally you would use
a bridge diode but what they are using are Moss vets for even more efficiency
at that step next we want to step up the voltage to 380 volts now this is
normally accomplished with a single rail in the X Series they're using two rails
this allows you to have less switching losses and just higher efficiency which
also means less heat from there what we have to do is take our 380 volts and
chop it up into AC so that we can take it down to 12 volts using a Transformer
now this is done using mosfets but the problem that they ran into is that they
are switching their mosfets so fast that if they were to use normal traditional
ones where you have like a screw that attaches it to your heat sink they're
having problems with the corona effect and then if that happens your Moss bed
explodes bad time time because their power supply exploding is fairly
undesirable they had to work with their manufacturer to do a special high
temperature press so that their mosfets could be attached to the heat sink here
without using any screws look at that
because 380 volts going to your CPU is undesirable we now have to step it down
with this Transformer to the 12 volts that you need this is typically done
with your Transformer and that's where a lot of the switching losses will occur
in your power supply they now have a multi layer Transformer to help reduce
those losses and reduce that heat even though this is the hottest component in
the whole thing now typically after the Transformer you have a full analog
signal but in this they have an MCU that
turns it into a digital signal and through the PM bus that's right here
it's able to communicate with the server or your computer so it knows exactly
sort of what the power supply is doing what the server is doing they can
communicate together for the maximum efficiency now now we have our 12vt that
is going to power most of the stuff in your computer but because 12vt only
hasn't caught on for some stupid reason we have to also get 3.3 and 5 volt now
this is done quite similarly to how you would do it in a traditional power
supply only difference is just components are bigger and better more
efficiency less heat now with all of that we were able to get our 1100 wats
out of this completely silently completely fanless and it has a platinum
efficiency rating to boot a couple more interesting things about this power
supply we have a USB protocol right here which just allows you to have some
software to see how the power supply is doing how everything's running that sort
of stuff our PM bus which we already talked about for servers and Industrial
things and also a little fan output this is just for if you don't have maybe
enough fan outputs on your motherboard you can have your fans controlled by the
power supply load directly from here you
guys won't be shock to know that all of that technology that the cram in here
will be coming at a price this is expected to be some somewhere between $650 and $700 when it launches later
this month you're looking for something a little bit smaller though they have
their V sfx Platinum now in the US in
spots with 110 voltage it's going to be 1,00 wat but if you're fortunate enough
to be somewhere that has 240 volt you can get 1,300 watts in a power supply of
this size that is absolutely Bonkers like just for context this right here is
a typical ATX power supply and this
thing's 1,300 wats I feel like we've already
nerded out enough in this so I'm not going to go into the details of how they
achiev that but the gist of it is buy very high quality components get very
high quality power supply one final thing that's nice are their new cables
it's just a very simple you know right angle connector into three guys so that
you don't accidentally you know not complete the connection and burn your house down and it's just going to be
awesome for when you're in like a really small computer and you just can't fit
something like this in there just like I can't fit any more really technical
information in this video if you guys are still around thank you so much for
watching this was absolutely brain breaking hit like get subscribed and
just have a fantastic all day see you later
