00:00:00,000 --> 00:00:06,120
we're here at cooler Masters booth at CES 2024 and the amount of engineering

2
00:00:04,560 --> 00:00:11,719
prowess that they have on display here is not what I was expecting at all their

3
00:00:08,719 --> 00:00:14,559
new X series of power supplies are just

4
00:00:11,719 --> 00:00:22,439
mind bogglingly cool this thing right here 1,00 watts and completely fanless

5
00:00:18,840 --> 00:00:26,800
look at this absolutely silent and if

6
00:00:22,439 --> 00:00:29,240
you put a fan on it it can go up to

7
00:00:26,800 --> 00:00:32,800
2800 watts of course you can't do in North America your Breakers would just

8
00:00:31,000 --> 00:00:38,879
blow but if you're in Europe you absolutely can this thing is actually

9
00:00:36,800 --> 00:00:42,960
Bonkers now there's two things that you need to have a fanless power supply

10
00:00:40,920 --> 00:00:46,559
first of all you just need cooling Cooler Master can do that that's not too

11
00:00:44,440 --> 00:00:50,960
hard and also it needs to just be incredibly efficient which is the

12
00:00:49,160 --> 00:00:54,520
particularly difficult part although first let's just have a little talk

13
00:00:52,800 --> 00:00:58,160
about the cooling the first way to dissipate heat is pretty simple you

14
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

15
00:01:00,359 --> 00:01:07,640
the heat away but they've gone one step further than that and the whole bottom

16
00:01:04,799 --> 00:01:13,240
of this power supply case is one great big heat sink so your main Transformer

17
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

18
00:01:15,759 --> 00:01:22,159
they have four heat pipes that are going to take that heat and spread it all

19
00:01:19,720 --> 00:01:26,960
across this extruded piece of aluminum right here this cooling solution is

20
00:01:24,159 --> 00:01:31,920
pretty sick but when we look at the actual way they've got the efficiency so

21
00:01:29,119 --> 00:01:35,920
great in this it is incredible just like this incredible segue to our sponsor

30
00:02:05,799 --> 00:02:13,280
link Down Below in the past though we have seen fanless power supplies but

31
00:02:09,920 --> 00:02:15,319
they've capped out around 750 watts and

32
00:02:13,280 --> 00:02:20,760
how Cooler Master was able to take this up to that 1100 was with the components

33
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

34
00:02:23,040 --> 00:02:31,000
to just sort of like a normal quite high-end power supply the first bit of

35
00:02:28,239 --> 00:02:34,920
your power supply is your dirty wall power comes in right here and needs to

36
00:02:33,160 --> 00:02:39,560
be cleaned up by your power factor correction now if this is not done

37
00:02:36,959 --> 00:02:43,440
properly your voltage and your current might be a little bit out of phase or

38
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

39
00:02:44,800 --> 00:02:51,840
it can be very inefficient now in a normal power supply you might have your

40
00:02:49,000 --> 00:02:56,400
medium flux chokes and those are pretty good but it's not like they're very

41
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

42
00:02:58,120 --> 00:03:04,680
the materials are quite expensive in these ones right here and it makes them

43
00:03:02,159 --> 00:03:09,799
able to really really get that noise down the next step is to take your AC

44
00:03:06,920 --> 00:03:14,080
input and change it over to DC using a bridge diode Well normally you would use

45
00:03:11,920 --> 00:03:19,159
a bridge diode but what they are using are Moss vets for even more efficiency

46
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

47
00:03:22,200 --> 00:03:28,760
normally accomplished with a single rail in the X Series they're using two rails

48
00:03:27,200 --> 00:03:33,319
this allows you to have less switching losses and just higher efficiency which

49
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

50
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

51
00:03:40,640 --> 00:03:47,319
now this is done using mosfets but the problem that they ran into is that they

52
00:03:44,439 --> 00:03:50,879
are switching their mosfets so fast that if they were to use normal traditional

53
00:03:48,959 --> 00:03:55,360
ones where you have like a screw that attaches it to your heat sink they're

54
00:03:52,720 --> 00:04:00,680
having problems with the corona effect and then if that happens your Moss bed

55
00:03:58,400 --> 00:04:04,439
explodes bad time time because their power supply exploding is fairly

56
00:04:02,519 --> 00:04:08,879
undesirable they had to work with their manufacturer to do a special high

57
00:04:06,640 --> 00:04:14,280
temperature press so that their mosfets could be attached to the heat sink here

58
00:04:11,280 --> 00:04:16,600
without using any screws look at that

59
00:04:14,280 --> 00:04:21,000
because 380 volts going to your CPU is undesirable we now have to step it down

60
00:04:18,840 --> 00:04:24,800
with this Transformer to the 12 volts that you need this is typically done

61
00:04:23,280 --> 00:04:29,120
with your Transformer and that's where a lot of the switching losses will occur

62
00:04:27,080 --> 00:04:33,880
in your power supply they now have a multi layer Transformer to help reduce

63
00:04:31,759 --> 00:04:38,320
those losses and reduce that heat even though this is the hottest component in

64
00:04:35,919 --> 00:04:44,160
the whole thing now typically after the Transformer you have a full analog

65
00:04:40,720 --> 00:04:46,160
signal but in this they have an MCU that

66
00:04:44,160 --> 00:04:50,080
turns it into a digital signal and through the PM bus that's right here

67
00:04:48,240 --> 00:04:54,840
it's able to communicate with the server or your computer so it knows exactly

68
00:04:52,639 --> 00:04:58,400
sort of what the power supply is doing what the server is doing they can

69
00:04:56,160 --> 00:05:02,360
communicate together for the maximum efficiency now now we have our 12vt that

70
00:05:00,720 --> 00:05:07,039
is going to power most of the stuff in your computer but because 12vt only

71
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

72
00:05:09,759 --> 00:05:14,919
this is done quite similarly to how you would do it in a traditional power

73
00:05:13,280 --> 00:05:19,400
supply only difference is just components are bigger and better more

74
00:05:17,080 --> 00:05:23,720
efficiency less heat now with all of that we were able to get our 1100 wats

75
00:05:21,639 --> 00:05:28,720
out of this completely silently completely fanless and it has a platinum

76
00:05:26,520 --> 00:05:32,479
efficiency rating to boot a couple more interesting things about this power

77
00:05:30,120 --> 00:05:35,400
supply we have a USB protocol right here which just allows you to have some

78
00:05:33,759 --> 00:05:39,000
software to see how the power supply is doing how everything's running that sort

79
00:05:37,479 --> 00:05:43,680
of stuff our PM bus which we already talked about for servers and Industrial

80
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

81
00:05:45,120 --> 00:05:52,840
enough fan outputs on your motherboard you can have your fans controlled by the

82
00:05:49,560 --> 00:05:55,199
power supply load directly from here you

83
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

84
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

85
00:06:03,600 --> 00:06:10,160
this month you're looking for something a little bit smaller though they have

86
00:06:07,120 --> 00:06:12,360
their V sfx Platinum now in the US in

87
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

88
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

89
00:06:21,160 --> 00:06:29,720
this size that is absolutely Bonkers like just for context this right here is

90
00:06:26,520 --> 00:06:30,680
a typical ATX power supply and this

91
00:06:29,720 --> 00:06:34,800
thing's 1,300 wats I feel like we've already

92
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

93
00:06:36,720 --> 00:06:44,000
achiev that but the gist of it is buy very high quality components get very

94
00:06:41,720 --> 00:06:48,160
high quality power supply one final thing that's nice are their new cables

95
00:06:45,880 --> 00:06:52,000
it's just a very simple you know right angle connector into three guys so that

96
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

97
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

98
00:06:59,520 --> 00:07:05,199
something like this in there just like I can't fit any more really technical

99
00:07:03,639 --> 00:07:09,039
information in this video if you guys are still around thank you so much for

100
00:07:07,240 --> 00:07:13,280
watching this was absolutely brain breaking hit like get subscribed and

101
00:07:11,160 --> 00:07:15,960
just have a fantastic all day see you later
