00:00:00.000 --> 00:00:06.120
we're here at cooler Masters booth at CES 2024 and the amount of engineering

00:00:04.560 --> 00:00:11.719
prowess that they have on display here is not what I was expecting at all their

00:00:08.719 --> 00:00:14.559
new X series of power supplies are just

00:00:11.719 --> 00:00:22.439
mind bogglingly cool this thing right here 1,00 watts and completely fanless

00:00:18.840 --> 00:00:26.800
look at this absolutely silent and if

00:00:22.439 --> 00:00:29.240
you put a fan on it it can go up to

00:00:26.800 --> 00:00:32.800
2800 watts of course you can't do in North America your Breakers would just

00:00:31.000 --> 00:00:38.879
blow but if you're in Europe you absolutely can this thing is actually

00:00:36.800 --> 00:00:42.960
Bonkers now there's two things that you need to have a fanless power supply

00:00:40.920 --> 00:00:46.559
first of all you just need cooling Cooler Master can do that that's not too

00:00:44.440 --> 00:00:50.960
hard and also it needs to just be incredibly efficient which is the

00:00:49.160 --> 00:00:54.520
particularly difficult part although first let's just have a little talk

00:00:52.800 --> 00:00:58.160
about the cooling the first way to dissipate heat is pretty simple you

00:00:56.359 --> 00:01:02.640
stick a big old heat sink on top of your components and uh yeah that just gets

00:01:00.359 --> 00:01:07.640
the heat away but they've gone one step further than that and the whole bottom

00:01:04.799 --> 00:01:13.240
of this power supply case is one great big heat sink so your main Transformer

00:01:10.360 --> 00:01:17.600
that goes from your 400 volt down to 12 is right over top of this coal plate and

00:01:15.759 --> 00:01:22.159
they have four heat pipes that are going to take that heat and spread it all

00:01:19.720 --> 00:01:26.960
across this extruded piece of aluminum right here this cooling solution is

00:01:24.159 --> 00:01:31.920
pretty sick but when we look at the actual way they've got the efficiency so

00:01:29.119 --> 00:01:35.920
great in this it is incredible just like this incredible segue to our sponsor

drive cages step into the world of Silent Computing with be quiet! at the

00:02:05.799 --> 00:02:13.280
link Down Below in the past though we have seen fanless power supplies but

00:02:09.920 --> 00:02:15.319
they've capped out around 750 watts and

00:02:13.280 --> 00:02:20.760
how Cooler Master was able to take this up to that 1100 was with the components

00:02:18.239 --> 00:02:25.519
in here so let's go from the wall to your computer and show you it compared

00:02:23.040 --> 00:02:31.000
to just sort of like a normal quite high-end power supply the first bit of

00:02:28.239 --> 00:02:34.920
your power supply is your dirty wall power comes in right here and needs to

00:02:33.160 --> 00:02:39.560
be cleaned up by your power factor correction now if this is not done

00:02:36.959 --> 00:02:43.440
properly your voltage and your current might be a little bit out of phase or

00:02:41.360 --> 00:02:47.120
the noise that's coming from your wall will cause that to be out of phase and

00:02:44.800 --> 00:02:51.840
it can be very inefficient now in a normal power supply you might have your

00:02:49.000 --> 00:02:56.400
medium flux chokes and those are pretty good but it's not like they're very

00:02:54.080 --> 00:03:00.560
fancy high flux chokes that they've got in this one the main thing is just that

00:02:58.120 --> 00:03:04.680
the materials are quite expensive in these ones right here and it makes them

00:03:02.159 --> 00:03:09.799
able to really really get that noise down the next step is to take your AC

00:03:06.920 --> 00:03:14.080
input and change it over to DC using a bridge diode Well normally you would use

00:03:11.920 --> 00:03:19.159
a bridge diode but what they are using are Moss vets for even more efficiency

00:03:16.519 --> 00:03:24.440
at that step next we want to step up the voltage to 380 volts now this is

00:03:22.200 --> 00:03:28.760
normally accomplished with a single rail in the X Series they're using two rails

00:03:27.200 --> 00:03:33.319
this allows you to have less switching losses and just higher efficiency which

00:03:31.200 --> 00:03:38.120
also means less heat from there what we have to do is take our 380 volts and

00:03:36.080 --> 00:03:42.920
chop it up into AC so that we can take it down to 12 volts using a Transformer

00:03:40.640 --> 00:03:47.319
now this is done using mosfets but the problem that they ran into is that they

00:03:44.439 --> 00:03:50.879
are switching their mosfets so fast that if they were to use normal traditional

00:03:48.959 --> 00:03:55.360
ones where you have like a screw that attaches it to your heat sink they're

00:03:52.720 --> 00:04:00.680
having problems with the corona effect and then if that happens your Moss bed

00:03:58.400 --> 00:04:04.439
explodes bad time time because their power supply exploding is fairly

00:04:02.519 --> 00:04:08.879
undesirable they had to work with their manufacturer to do a special high

00:04:06.640 --> 00:04:14.280
temperature press so that their mosfets could be attached to the heat sink here

00:04:11.280 --> 00:04:16.600
without using any screws look at that

00:04:14.280 --> 00:04:21.000
because 380 volts going to your CPU is undesirable we now have to step it down

00:04:18.840 --> 00:04:24.800
with this Transformer to the 12 volts that you need this is typically done

00:04:23.280 --> 00:04:29.120
with your Transformer and that's where a lot of the switching losses will occur

00:04:27.080 --> 00:04:33.880
in your power supply they now have a multi layer Transformer to help reduce

00:04:31.759 --> 00:04:38.320
those losses and reduce that heat even though this is the hottest component in

00:04:35.919 --> 00:04:44.160
the whole thing now typically after the Transformer you have a full analog

00:04:40.720 --> 00:04:46.160
signal but in this they have an MCU that

00:04:44.160 --> 00:04:50.080
turns it into a digital signal and through the PM bus that's right here

00:04:48.240 --> 00:04:54.840
it's able to communicate with the server or your computer so it knows exactly

00:04:52.639 --> 00:04:58.400
sort of what the power supply is doing what the server is doing they can

00:04:56.160 --> 00:05:02.360
communicate together for the maximum efficiency now now we have our 12vt that

00:05:00.720 --> 00:05:07.039
is going to power most of the stuff in your computer but because 12vt only

00:05:04.680 --> 00:05:11.639
hasn't caught on for some stupid reason we have to also get 3.3 and 5 volt now

00:05:09.759 --> 00:05:14.919
this is done quite similarly to how you would do it in a traditional power

00:05:13.280 --> 00:05:19.400
supply only difference is just components are bigger and better more

00:05:17.080 --> 00:05:23.720
efficiency less heat now with all of that we were able to get our 1100 wats

00:05:21.639 --> 00:05:28.720
out of this completely silently completely fanless and it has a platinum

00:05:26.520 --> 00:05:32.479
efficiency rating to boot a couple more interesting things about this power

00:05:30.120 --> 00:05:35.400
supply we have a USB protocol right here which just allows you to have some

00:05:33.759 --> 00:05:39.000
software to see how the power supply is doing how everything's running that sort

00:05:37.479 --> 00:05:43.680
of stuff our PM bus which we already talked about for servers and Industrial

00:05:41.120 --> 00:05:47.800
things and also a little fan output this is just for if you don't have maybe

00:05:45.120 --> 00:05:52.840
enough fan outputs on your motherboard you can have your fans controlled by the

00:05:49.560 --> 00:05:55.199
power supply load directly from here you

00:05:52.840 --> 00:05:58.759
guys won't be shock to know that all of that technology that the cram in here

00:05:57.199 --> 00:06:05.280
will be coming at a price this is expected to be some somewhere between $650 and $700 when it launches later

00:06:03.600 --> 00:06:10.160
this month you're looking for something a little bit smaller though they have

00:06:07.120 --> 00:06:12.360
their V sfx Platinum now in the US in

00:06:10.160 --> 00:06:16.599
spots with 110 voltage it's going to be 1,00 wat but if you're fortunate enough

00:06:14.720 --> 00:06:24.080
to be somewhere that has 240 volt you can get 1,300 watts in a power supply of

00:06:21.160 --> 00:06:29.720
this size that is absolutely Bonkers like just for context this right here is

00:06:26.520 --> 00:06:30.680
a typical ATX power supply and this

00:06:29.720 --> 00:06:34.800
thing's 1,300 wats I feel like we've already

00:06:33.360 --> 00:06:39.560
nerded out enough in this so I'm not going to go into the details of how they

00:06:36.720 --> 00:06:44.000
achiev that but the gist of it is buy very high quality components get very

00:06:41.720 --> 00:06:48.160
high quality power supply one final thing that's nice are their new cables

00:06:45.880 --> 00:06:52.000
it's just a very simple you know right angle connector into three guys so that

00:06:50.319 --> 00:06:57.120
you don't accidentally you know not complete the connection and burn your house down and it's just going to be

00:06:55.360 --> 00:07:01.800
awesome for when you're in like a really small computer and you just can't fit

00:06:59.520 --> 00:07:05.199
something like this in there just like I can't fit any more really technical

00:07:03.639 --> 00:07:09.039
information in this video if you guys are still around thank you so much for

00:07:07.240 --> 00:07:13.280
watching this was absolutely brain breaking hit like get subscribed and

00:07:11.160 --> 00:07:15.960
just have a fantastic all day see you later
