0:00 when it comes to motherboards everyone wants something different for their PC
0:04 some people are like yeah bring on the USB ports others want support for like
0:09 multiple graphics cards and others just want like sweet Dragon graphics on their
0:13 heat sinks but there's one important aspect of motherboard design that you'd
0:17 be hard pressed to find in a spec sheet from your favorite retailer but is
0:22 extremely important the voltage
0:25 regulator modules or vrm so why are they
0:30 important and how do you know what to look for when choosing a motherboard
0:33 great question and it might help to think of the vrm as kind of like a mini
0:38 power supply just like your actual main computer power supply takes 120 or 240
0:44 volts from the wall and steps it down to 12 volts not to mention DC current the
0:50 motherboard vrm does this a second time
0:53 to provide your CPU with the you know
0:56 like 1 to 1 and 1/2 volts or whatever it needs to operate without cooking like a
1:02 lobster but unlike your power supply the vrm isn't one big bulky thing in a box
1:08 that's easy to spot it's actually made up of a few different components number
1:13 one is mosfets which are often located under those big heat sinks that surround
1:17 your CPU socket indicating that they do give off some heat so the processor
1:22 tells the mosfets yo dog I need 1.2 volts or whatever and the mosfets then
1:27 deliver exactly that much power to to the CPU you also have your chokes those
1:33 blocky things next to the mosfets that stabilize the current as well as
1:38 capacitors which both serve as temporary storage for electricity and protect
1:43 against sudden voltage spikes now admittedly these things aren't as
1:48 exciting as putting in a new $400 graphics card or whatever but the
1:52 quality of your vrms can make a huge difference for your PC for starters
1:57 cheaply made vrms can lead to system instability and crashes even at stock
2:02 speed and very poor quality vrms can
2:05 even mess up the power delivery to the point where they'll damage your other
2:09 expensive components and if you're overclocking uh you won't get very far
2:14 with a poorly engineered vrm since the correct voltages are so important to
2:19 system stability when you're pushing your components beyond their rated
2:23 speeds okay lonus then so how do I know what to look for I've never even heard
2:27 of people talking about VR before well a couple of simple tips can
2:33 help you make sure you don't end up having to make a long trip to the tshi
2:37 station to pick up a replacement power converter one of the easiest things to
2:41 do is just count up the number of chokes on the motherboard you see motherboards
2:46 split up power delivery to the CPU into a number of phases and more phases means
2:51 the power is split more ways lightening the load on each phase which in turn can
2:56 lead to Greater stability each choke on your motherboard corresponds to one
3:01 power phase and usually all but one or two of these around the CPU socket are
3:06 reserved for your CPU cores entry-level
3:10 boards will usually have three or four phase CPU power but higher quality
3:15 boards can have 6 eight or even more
3:18 it's also a good idea to pick up a board with solidstate capacitors cheaper
3:23 capacitors contain a conducting liquid which can cause problems if they're not
3:27 made correctly and even if they are made corre irly they're very likely to bulge
3:31 and rupture or even explode over time which is what happened to a lot of
3:35 people during the infamous capacitor plague of the mid 2000s solid capacitors
3:41 not only largely eliminate these risks but they also have wider temperature
3:45 tolerances and a longer lifespan but are
3:49 these things even going to be a big deal forever I mean CPUs are getting to the
3:52 point where they can do so much more with so much less power I mean for
3:56 example Intel Skylake CPUs don't need as
4:00 many power phases for a solid overclock as previous generations and AMD's
4:04 upcoming Zen architecture looks to be much more power efficient as well
4:09 nevertheless you obviously want to make sure that whatever board you drop your
4:13 hard-earned cash on won't fail more quickly than your attempt to go pro in
4:18 Starcraft and on the subject of going pro why have a shoddy website anymore
4:24 it's not that expensive on squarespace.com you can pick yourself up
4:28 a website the hosting service behind it
4:32 if you pay for a year at a time you can even get your domain thrown in for free
4:36 and you can get the support via live chat and email 24 hours a day to help
4:41 you build a website that functions and looks great whether it's on people's
4:46 phones or their tablets or their computers or whatever else the case may
4:50 be whatever kind of website you want to build a you know company profile website
4:54 with neat little pictures of all your employees or like a blog or like a
4:58 little a little store where you sell arts and crafts Squarespace will have a
5:02 template for you and it's easy to use so
5:06 you start your trial with no credit card required by heading over to squarespace.com then when you decide to
5:11 sign up for Squarespace in the long term use offer code Linus to get 10% off your
5:16 first purchase so that's squarespace.com and go there and do that thing so thanks
5:23 for watching guys if you like the video do that thing if you didn't then do the other thing uh leave a comment with
5:27 video suggestions if you have com with video suggestions don't forget to
5:31 subscribe and follow and if you're looking for something else to watch we had a great video over on our lonus Tech
5:35 tips Channel taking a bunch of different graphics cards and finding out what the
5:40 actual difference in performance from one card to another in spite of them
5:44 being identical can be very interesting stuff
