Hi, this is Wayne again with a topic “This is unbelievable… – Cooler Master at CES 2024”.
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 article, if you guys are still around. Thank you so much for watching this was absolutely brain.
