00:00:00,000 --> 00:00:03,440
We're here at Cooler Master's booth at CES 2024,

2
00:00:03,440 --> 00:00:08,640
and the amount of engineering prowess that they have on display here is not what I was expecting at all.

3
00:00:08,640 --> 00:00:13,920
Their new X series of power supplies are just mind-bogglingly cool.

4
00:00:13,920 --> 00:00:18,760
This thing right here, 1,100 watts and completely fanless.

5
00:00:18,760 --> 00:00:22,280
Look at this, absolutely silent.

6
00:00:22,280 --> 00:00:27,280
And if you put a fan on it, it can go up to 2,800 watts.

7
00:00:28,280 --> 00:00:31,520
Of course, you can't do it in North America, your breakers would just blow,

8
00:00:31,520 --> 00:00:37,480
but if you're in Europe, you absolutely can't. This thing is actually bonkers.

9
00:00:37,480 --> 00:00:41,040
Now, there's two things that you need to have a fanless power supply.

10
00:00:41,040 --> 00:00:44,880
First of all, you just need cooling. Cooler Master can do that, that's not too hard.

11
00:00:44,880 --> 00:00:48,200
And also it needs to just be incredibly efficient,

12
00:00:48,200 --> 00:00:52,920
which is the particularly difficult part. Although first, let's just have a little talk

13
00:00:52,920 --> 00:00:56,400
about the cooling. The first way to dissipate heat is pretty simple.

14
00:00:56,400 --> 00:01:01,520
You stick a big old heat sink on top of your components and yeah, that just gets the heat away,

15
00:01:01,520 --> 00:01:06,760
but they've gone one step further than that. And the whole bottom of this power supply case

16
00:01:06,760 --> 00:01:12,280
is one great big heat sink. So your main transformer that goes from your 400 volt

17
00:01:12,280 --> 00:01:15,760
down to 12 is right over top of this cold plate.

18
00:01:15,760 --> 00:01:21,480
And they have four heat pipes that are going to take that heat and spread it all across this extruded piece

19
00:01:21,480 --> 00:01:25,480
of aluminum right here. As cooling solution is pretty sick,

20
00:01:25,520 --> 00:01:30,120
but when we look at the actual width, they've got the efficiency so great in this,

21
00:01:30,120 --> 00:01:34,280
it is incredible. Just like this, incredible segue to our sponsor.

22
00:01:34,280 --> 00:01:40,160
In the past though, we have seen fanless power supplies, but they've capped out at around 750 watts.

23
00:01:40,160 --> 00:01:45,680
And how Cooler Master was able to take this up to that 1100 was with the components in here.

24
00:01:45,680 --> 00:01:48,920
So let's go from the wall to your computer

25
00:01:48,920 --> 00:01:54,560
and show you it compared to just sort of like a normal quite high end power supply.

26
00:01:54,560 --> 00:01:57,880
The first bit of your power supply is when your dirty wall

27
00:01:57,880 --> 00:02:02,680
power comes in right here and needs to be cleaned up by your power factor correction.

28
00:02:02,680 --> 00:02:08,080
Now, if this is not done properly, your voltage and your current might be a little bit out of phase

29
00:02:08,080 --> 00:02:11,720
or the noise that's coming from your wall will cause that to be out of phase

30
00:02:11,720 --> 00:02:15,200
and it can be very inefficient. Now, in a normal power supply,

31
00:02:15,200 --> 00:02:19,600
you might have your medium flux chokes and those are pretty good,

32
00:02:19,600 --> 00:02:22,960
but it's not like they're very fancy high flux chokes

33
00:02:22,960 --> 00:02:26,260
that they've got in this one. The main thing is just that the materials

34
00:02:26,260 --> 00:02:32,140
are quite expensive in these ones right here and it makes them able to really, really get that noise down.

35
00:02:32,140 --> 00:02:37,980
The next step is to take your AC input and change it over to DC using a bridge diode.

36
00:02:37,980 --> 00:02:42,060
Well, normally you would use a bridge diode, but what they are using are MOSFETs

37
00:02:42,060 --> 00:02:48,860
for even more efficiency at that step. Next, we want to step up the voltage to 380 volts.

38
00:02:48,860 --> 00:02:54,180
Now, this is normally accomplished with a single rail in the X series, they're using two rails.

39
00:02:54,220 --> 00:02:59,820
This allows you to have less switching losses and just higher efficiency, which also means less heat.

40
00:02:59,820 --> 00:03:02,820
From there, what we have to do is take our 380 volts

41
00:03:02,820 --> 00:03:07,660
and chop it up into AC so that we can take it down to 12 volts using a transformer.

42
00:03:07,660 --> 00:03:11,060
Now, this is done using MOSFETs, but the problem that they ran into

43
00:03:11,060 --> 00:03:14,260
is that they are switching their MOSFETs so fast

44
00:03:14,260 --> 00:03:19,620
that if they were to use normal traditional ones or you have like a screw that attaches it to your heat sink,

45
00:03:19,620 --> 00:03:27,300
you're having problems with the corona effect and then if that happens, your MOSFET explodes, bad time.

46
00:03:27,300 --> 00:03:30,500
Because your power supply exploding is fairly undesirable,

47
00:03:30,500 --> 00:03:34,900
they had to work with their manufacturer to do a special high temperature press

48
00:03:34,900 --> 00:03:38,140
so that their MOSFETs could be attached to the heat sink here

49
00:03:38,140 --> 00:03:41,260
without using any screws, look at that.

50
00:03:41,260 --> 00:03:44,300
Because 380 volts going to your CPU is undesirable,

51
00:03:44,300 --> 00:03:49,020
we have to step it down with this transformer to the 12 volts that you need.

52
00:03:49,020 --> 00:03:53,540
This is typically done with your transformer and that's where a lot of the switching losses

53
00:03:53,540 --> 00:03:58,020
will occur in your power supply. They now have a multi-layer transformer

54
00:03:58,020 --> 00:04:04,220
to help reduce those losses and reduce that heat, even though this is the hottest component in the whole thing.

55
00:04:04,220 --> 00:04:08,500
Now, typically after the transformer, you have a full analog signal,

56
00:04:08,500 --> 00:04:12,980
but in this they have an MCU that turns it into a digital signal

57
00:04:12,980 --> 00:04:18,340
and through the PM bus that's right here, it's able to communicate with the server or your computer

58
00:04:18,340 --> 00:04:21,780
so it knows exactly sort of what the power supply is doing,

59
00:04:21,780 --> 00:04:26,420
what the server is doing, they can communicate together for the maximum efficiency.

60
00:04:26,420 --> 00:04:30,220
Now we have our 12 volts that is going to power most of the stuff in your computer,

61
00:04:30,220 --> 00:04:34,020
but because 12 volt only hasn't caught on for some stupid reason,

62
00:04:34,020 --> 00:04:39,380
we have to also get 3.3 and 5 volt. Now this is done quite similarly to how you would do it

63
00:04:39,380 --> 00:04:43,860
in a traditional power supply, only difference is just components are bigger and better,

64
00:04:43,860 --> 00:04:49,380
more efficiency, less heat. Now with all of that, we were able to get our 1100 watts out of this

65
00:04:49,380 --> 00:04:55,180
completely silently, completely fanlessly, and it has a platinum efficiency rating to boot.

66
00:04:55,180 --> 00:04:59,460
A couple more interesting things about this power supply, we have a USB protocol right here,

67
00:04:59,460 --> 00:05:02,780
which just allows you to have some software to see how the power supply is doing,

68
00:05:02,780 --> 00:05:06,700
how everything's running, that sort of stuff. Our PM bus, which we already talked about

69
00:05:06,700 --> 00:05:10,540
for servers and industrial things, and also a little fan output.

70
00:05:10,540 --> 00:05:14,780
This is just for, if you don't have maybe enough fan outputs on your motherboard,

71
00:05:14,820 --> 00:05:19,700
you can have your fans controlled by the power supply load directly from here.

72
00:05:19,700 --> 00:05:24,200
You guys won't be shocked to know that all of that technology that they've cramped in here

73
00:05:24,200 --> 00:05:29,260
will be coming at a price. This is expected to be somewhere between 650 and $700

74
00:05:29,260 --> 00:05:33,860
when it launches later this month. You're looking for something a little bit smaller though,

75
00:05:33,860 --> 00:05:38,740
they have their VSFX platinum. Now in the US and spots with 110 voltage,

76
00:05:38,740 --> 00:05:43,540
it's going to be 1100 watts, but if you're fortunate to be somewhere that has 240 volt,

77
00:05:43,540 --> 00:05:48,540
you can get 1300 watts in a power supply of this size.

78
00:05:49,100 --> 00:05:52,340
That is absolutely bonkers. Like just for context,

79
00:05:52,340 --> 00:05:56,540
this right here is a typical ATX power supply.

80
00:05:56,540 --> 00:05:59,660
This thing's 1300 watts.

81
00:05:59,660 --> 00:06:03,220
I feel like we've already nerded out enough in this, so I'm not going to go into the details

82
00:06:03,220 --> 00:06:08,140
of how they achieved that, but the gist of it is buy very high quality components,

83
00:06:08,140 --> 00:06:12,820
get very high quality power supply. One final thing that's nice are their new cables.

84
00:06:12,820 --> 00:06:16,180
It's just a very simple right angle connector

85
00:06:16,180 --> 00:06:21,340
into three guys so that you don't accidentally know not completely the connection and burn your house down.

86
00:06:21,340 --> 00:06:24,860
And it's just going to be awesome for when you're in like a really small computer

87
00:06:24,860 --> 00:06:28,340
and you just can't fit something like this in there.

88
00:06:28,340 --> 00:06:31,900
Just like I can't fit any more really technical information in this video.

89
00:06:31,900 --> 00:06:36,700
If you guys are still around, thank you so much for watching. This was absolutely brain breaking.

00:06:36,700 --> 00:06:39,940
Hit like, get subscribed and just have a fantastic old day.

91
00:06:39,940 --> 00:06:40,780
