 This is a very cool product. This is I believe the second fanless power supply that I have unboxed But what's really special about this one is the fact that it achieves its fanless design Not by the use of extremely heavy heat sinks, but rather through incredible efficiency So this is a 400 watt unit from Seasonic, and it is 80 plus gold certified We're starting to see more and more 80 plus gold certified power supplies But this is the first one that uses that incredible efficiency now remember efficiency means How much power it can produce versus how much excess? Random heat that it outputs so it uses that efficiency to output so little heat that it can just run without a fan at all So you can see here. We have a summary of the connectors. Oh, this is also really cool single 12-volt 33 amp rail So this is a single rail design 80 plus gold fanless power supply Let's have a look at the back here, so see Sonic has a Slightly different design for the output Okay, you know what I'll just let you look at the diagram because I haven't really studied it ahead ahead of time But basically what they're able to do is by keeping the amperages lower within the power supply Overall they're able to lose less efficiency that way so they have high current gold plated terminals I guess we can start the unboxing now high reliability 105 degree grade a capacitors conductive Okay, so solid solid capacitors and a five-year warranty on this unit is fanless zero decibels So this would be great for a media PC for You know what this would be great for almost any PC because the reality of it is if you're running a single graphics card like single PC IE 16 or a pin connector and you're running like almost any almost any CPU on the market like if you just need a computer With like good CPU lots of RAM you throw an SSD in there a hard drive in there And you don't need like a high-end video card or anything like that This is like perfect because you can just have perfect silence for your power supply and 400 watts really is enough For almost any PC unless you start throwing like overclocking and high-end graphics cards into the mix So for is that okay and only should operate in a well-designed system chassis that provides good ventilation For modern computer components, so you don't want to throw this in a sealed box is basically what they're saying you need to use a proper case that has Probably at least one fan in it to provide some incidental airflow to your power supply So here's a summary of some of the extra features while special features gets all of two pages in this in this manual out Of eight in English so go ahead and pause the video and read through that if you so desire Here we are a little bit more about it their whole X series So it goes all the way from 400 watt for fanless units all the way up to 1200 watts just incredible and We see warranty and disclaimer some safety notes very nice just some modular power supply to Modular okay cool. So why don't we have a quick look here at what we get in terms of accessories Some see sonic cable ties very nice We get some some zip ties and then we get a nice little see sonic sticker powered by see sonic Alright, let's have a look at the power supply first for a change I normally look at the cables first, but we're gonna do it the other way around nice sticker. It's a very nice sticker Feels like quality okay, so I actually don't have my tripod propped against me today, so Maybe I'll just pause the video for a sec alright as soon as we take the power supply out of the satin e-sleeve that it comes Packed in we see a sticker on top with that says install with the ventilation top cover Facing up and please remove this label before use So let's go around to the side where we also have some more ventilation here at the front we have the modular interface We're gonna go ahead and remove that label on the other side. We have some more ventilation holes So I guess presumably the way this works is simply via convection So as components in here heat up the heat gets Exhausted out here just because of the simple fact that heat does rise and then see sonic cable ties And then see sonic has strategically placed the intake holes which are presumably at the back and Here along the sides so and the front so that the air comes in cools the most critical components first And then once it's heated rises out the top of the power supply, so it's very cool looking you know It's not nearly as heavy as As the other fanless power supply that I had a look at which is kind of kind of refreshing in some ways because it means That your system doesn't already weigh as much as a like wheelbarrow full of bricks before you even start putting other components in it So there's the full specs there I think we already showed this on the side and you can see even at the bottom of the unit There are a few ventilation holes so these are likely strategically placed so they can get a little bit of airflow to some critical Component that needs to get a little bit of cooling done, so let's have a look at the modular cables that are included With the X-series 400 watt fanless power supply Whoa, okay I might have to pause for a second again here Actually here, I'll just get someone else to hold the camera Rumble can you hold the camera for me? Thanks bud Alright so inside here we will find One modular to a 4 plus 4 pin power connector so that's either a 4 pin or an 8 pin depending on what your motherboard requires Then we have a PCI Express 6 plus 2 pin as well as a 24 pin power for your motherboard In the next bag, in the handy dandy cable holding bag, we have, oh okay, we've also got a power cord for the back of the unit And then in here we will find SATA and Molex cables Okay so we've got one single Molex connector, no two Molex connectors And then we have, you know what, let's just crack this open here so I can clearly see what I'm doing Alright what do we have? So this one has two SATA, this one has, this is a Molex to two floppy adapter So you can use that if you still require one of those connectors We have a triple SATA connector and then we have three Molex and a two Molex So that's all the modular cables Now I'm just going to check really quickly if you can actually plug in all modular cables at the same time And it looks like you cannot, so you're going to have to decide which three of these four connectors you are going to want to plug in So you can either have a 5 SATA and 3 Molex or a 5 Molex and 3 SATA So thank you for checking out my unboxing of the Seasonic X Series 400 watt 80 plus gold power supply And I love those gold heat sinks in there, just a nice little accent
