WEBVTT 00:00:00.000 --> 00:00:03.440 We're here at Cooler Master's booth at CES 2024, 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. 00:00:08.640 --> 00:00:13.920 Their new X series of power supplies are just mind-bogglingly cool. 00:00:13.920 --> 00:00:18.760 This thing right here, 1,100 watts and completely fanless. 00:00:18.760 --> 00:00:22.280 Look at this, absolutely silent. 00:00:22.280 --> 00:00:27.280 And if you put a fan on it, it can go up to 2,800 watts. 00:00:28.280 --> 00:00:31.520 Of course, you can't do it in North America, your breakers would just blow, 00:00:31.520 --> 00:00:37.480 but if you're in Europe, you absolutely can't. This thing is actually bonkers. 00:00:37.480 --> 00:00:41.040 Now, there's two things that you need to have a fanless power supply. 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. 00:00:44.880 --> 00:00:48.200 And also it needs to just be incredibly efficient, 00:00:48.200 --> 00:00:52.920 which is the particularly difficult part. Although first, let's just have a little talk 00:00:52.920 --> 00:00:56.400 about the cooling. The first way to dissipate heat is pretty simple. 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, 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 00:01:06.760 --> 00:01:12.280 is one great big heat sink. So your main transformer that goes from your 400 volt 00:01:12.280 --> 00:01:15.760 down to 12 is right over top of this cold plate. 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 00:01:21.480 --> 00:01:25.480 of aluminum right here. As cooling solution is pretty sick, 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, 00:01:30.120 --> 00:01:34.280 it is incredible. Just like this, incredible segue to our sponsor. 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. 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. 00:01:45.680 --> 00:01:48.920 So let's go from the wall to your computer 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. 00:01:54.560 --> 00:01:57.880 The first bit of your power supply is when your dirty wall 00:01:57.880 --> 00:02:02.680 power comes in right here and needs to be cleaned up by your power factor correction. 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 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 00:02:11.720 --> 00:02:15.200 and it can be very inefficient. Now, in a normal power supply, 00:02:15.200 --> 00:02:19.600 you might have your medium flux chokes and those are pretty good, 00:02:19.600 --> 00:02:22.960 but it's not like they're very fancy high flux chokes 00:02:22.960 --> 00:02:26.260 that they've got in this one. The main thing is just that the materials 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. 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. 00:02:37.980 --> 00:02:42.060 Well, normally you would use a bridge diode, but what they are using are MOSFETs 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. 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. 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. 00:02:59.820 --> 00:03:02.820 From there, what we have to do is take our 380 volts 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. 00:03:07.660 --> 00:03:11.060 Now, this is done using MOSFETs, but the problem that they ran into 00:03:11.060 --> 00:03:14.260 is that they are switching their MOSFETs so fast 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, 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. 00:03:27.300 --> 00:03:30.500 Because your power supply exploding is fairly undesirable, 00:03:30.500 --> 00:03:34.900 they had to work with their manufacturer to do a special high temperature press 00:03:34.900 --> 00:03:38.140 so that their MOSFETs could be attached to the heat sink here 00:03:38.140 --> 00:03:41.260 without using any screws, look at that. 00:03:41.260 --> 00:03:44.300 Because 380 volts going to your CPU is undesirable, 00:03:44.300 --> 00:03:49.020 we have to step it down with this transformer to the 12 volts that you need. 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 00:03:53.540 --> 00:03:58.020 will occur in your power supply. They now have a multi-layer transformer 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. 00:04:04.220 --> 00:04:08.500 Now, typically after the transformer, you have a full analog signal, 00:04:08.500 --> 00:04:12.980 but in this they have an MCU that turns it into a digital signal 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 00:04:18.340 --> 00:04:21.780 so it knows exactly sort of what the power supply is doing, 00:04:21.780 --> 00:04:26.420 what the server is doing, they can communicate together for the maximum efficiency. 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, 00:04:30.220 --> 00:04:34.020 but because 12 volt only hasn't caught on for some stupid reason, 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 00:04:39.380 --> 00:04:43.860 in a traditional power supply, only difference is just components are bigger and better, 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 00:04:49.380 --> 00:04:55.180 completely silently, completely fanlessly, and it has a platinum efficiency rating to boot. 00:04:55.180 --> 00:04:59.460 A couple more interesting things about this power supply, we have a USB protocol right here, 00:04:59.460 --> 00:05:02.780 which just allows you to have some software to see how the power supply is doing, 00:05:02.780 --> 00:05:06.700 how everything's running, that sort of stuff. Our PM bus, which we already talked about 00:05:06.700 --> 00:05:10.540 for servers and industrial things, and also a little fan output. 00:05:10.540 --> 00:05:14.780 This is just for, if you don't have maybe enough fan outputs on your motherboard, 00:05:14.820 --> 00:05:19.700 you can have your fans controlled by the power supply load directly from here. 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 00:05:24.200 --> 00:05:29.260 will be coming at a price. This is expected to be somewhere between 650 and $700 00:05:29.260 --> 00:05:33.860 when it launches later this month. You're looking for something a little bit smaller though, 00:05:33.860 --> 00:05:38.740 they have their VSFX platinum. Now in the US and spots with 110 voltage, 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, 00:05:43.540 --> 00:05:48.540 you can get 1300 watts in a power supply of this size. 00:05:49.100 --> 00:05:52.340 That is absolutely bonkers. Like just for context, 00:05:52.340 --> 00:05:56.540 this right here is a typical ATX power supply. 00:05:56.540 --> 00:05:59.660 This thing's 1300 watts. 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 00:06:03.220 --> 00:06:08.140 of how they achieved that, but the gist of it is buy very high quality components, 00:06:08.140 --> 00:06:12.820 get very high quality power supply. One final thing that's nice are their new cables. 00:06:12.820 --> 00:06:16.180 It's just a very simple right angle connector 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. 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 00:06:24.860 --> 00:06:28.340 and you just can't fit something like this in there. 00:06:28.340 --> 00:06:31.900 Just like I can't fit any more really technical information in this video. 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. 00:06:39.940 --> 00:06:40.780 See you later.
