Power it up, cool it down, power it up, cool
it down, power it up, cool it down! Hey there! I’m Trisha Hershberger and
you’re watching DIYin5, the show where we
make complex tech seem simple. This episode is part of our ‘build your
own pc’ series and today we’ll be focusing on power and cooling options. To see the other videos in the series, be
sure to subscribe to the channel and check out all
our other tech breakdowns. Whether we’re talking PCs, business or the
ability of hoverboards to zoom over water, most people would argue that more power is
better, but that’s not necessarily true! You’ll want to size your PSU
appropriately for your system. Too high of a load into a basic system actually decreases your efficiency and costs you more
money over time. When it comes to your power supply unit, or
PSU, the wattage listed is the maximum amount of energy it could possibly supply. A great tool I like to use to determine how
many watts you might need is the OuterVision Power Supply Calculator and it’s linked in the description below. Your’er welcome! After determining the amount of power,
then you need to determine if you want a modular
or semi-modular PSU. A full modular PSU has
no cables pre-attached whatsoever. This is the most expensive way to go but it
allows you to only attach the cables you need for better airflow
and less clutter. A semi-modular PSU has the essential cables
pre-attached and is a bit less expensive. A non-modular PSU has all necessary cables
pre-attached, including some you may not even use, and may lead to a cable management nightmare
– or not – totally up to you. Each power supply unit will have an efficiency
rating – which is the amount of power provided to the components divided by the amount of
power drawn at the wall. For example a 50% efficiency gives 50W to
the system but takes 100W from the grid. A better efficiency rating means less waste
and waste is bad for heat and can potentially
damage other components. Remember back when we covered choosing the
right case for your build? Some cases come with a PSU already mounted
inside and while this definitely makes the overall build a little easier, it also can
limit your options. Something to think about… Speaking of heat, heat is the ultimate enemy
of any system and must be eliminated at all costs! Where there is heat, there must be a way to get rid of it,
hence the importance of cooling methods in your PC. Different components will come with their
own cooling means directly from their manufacturer, and these stock options
will get the job done. But if you really wanna cool things down,
and do so quietly and with a bit of pizazz, then here’s where you can get fancy. You can cool your system down with aftermarket
coolers – either using air or liquid. Whoo! It’s a little hot in there! Let’s get some liquid cooling up in this piece, hu? Whoo! Much better! No, don’t ever do that! Yep, I did just say liquid
as in putting liquid in your PC. We’ll get to that. Air is the cheaper of the two options and
you can choose the size, speed and look of the fan you want to install. Some fans are designed for high airflow while
others are designed for static pressure. High airflow fans are great for cases, moving
the air from front to back and bottom to top, while static pressure fans are great at pushing
air in a stronger way toward a specific component, or for a case that has small vents or something
blocking the airflow. Whether it’s for funky aesthetics, less
noise, or the incredible cooling results achieved, you may be considering liquid cooling. Liquid cooling can be 2-10 times more effective
than air cooling, it’s super quiet and it makes your whole system look like a science
experiment in a good way. People used to homemake systems using things
found around the house like aquarium pumps to get these results, but I’m happy to say
that it’s a bit more standardized now. You can either purchase the parts needed individually
– water blocks, pump, radiator and fan, water reservoir – or you can purchase a starter kit or even All in One
system to make things a bit easier for your first time. If you are up for the challenge,
liquid cooling can be a ton of fun. Alright, if you’ve been following the series,
we’ve now covered all the major components required to build your very own PC!!! Other things I’ll quickly
mention are an optical drive. These are not really
used anymore but they’re cheap and a real pain in the butt when you need one and don’t have it. A wireless card if your system doesn’t have a direct line you can get an external USB connected wireless card or an internal component with better antennas
for better reception. A Bluetooth USB adapter,
another inexpensive external option. A sound card, when
on-motherboard audio isn’t enough. And of course, peripherals – your
command center to navigate your system. Ok, that about does it! Please, please, please let us know in the comments how
your build is going and if you have any questions. I’m excited for you and
cannot wait to see what you come up with. Building your own pc is not only grade A bragging
rights, it’s also the best way to get the ultimate performance
bang for your buck. If this video helped you out in anyway, please
give it a like and a share. My name’s Trisha Hershberger and I’ll
see you back here soon with more DIYin5.

    I've built a few small power supplies myself (for smaller circuits) and it's true about the efficiency not being good for larger supplies running smaller loads. The buck/boost switching converters have to be run in the load range they're designed for. I've literally looked at hundreds of Efficiency vs Load graphs when designing power supplies to find the perfect chip, otherwise I'd end up with really poor battery life. It could mean the difference between say, 45% efficiency or 93% efficiency.

    I'm personally already quite far along knowledgewise when it comes to building, customization, and overclocking. At the same time I watched you're videos just for curiosity sake and you do present things in a very straight forward and pragmatic manner. Great job! If anyone has questions on the enthusiasts side of things I typically am a confirmed amd overclocker as a hobbyist. I do have decent intel information but just happen to have more experience with amd gpus and cpus, socs, etc. Feel free to ask about things. No spam intended just happy to offer experience. I have knowledge with everything from cpu overclocking, cpu undervolting, fx series, ryzen series, old intel quad 2 core, ram overclocking and voktage including timings guides from ddr2 ddr3 to ddr4. Cheers all

    Over sizing a PSU should not cause a lack of efficiency. Modern switching mode power supply use a PWM (pulse width modulation) control IC, to change the rate at which the power is feed into the snitching transformer, based on feedback. Now power supplies have multi voltage outputs, but by the nature of the PC the largest current draw is on the VDC line for the processor and other logic devices. This is the output voltage that the PWM compaitor uses to regulate it output width. This should properly regulate the power efficiency With the small cost difference between various wattage of power supply, over sizing a PSU should actually be go for the system stability, since the PSU has to put out less effort.

    I build my first PC 2 years ago and it is both rewarding and nerve-wrecking at the same time. I saw through your last few videos. I would mention in selecting cases about the availability of drive bays (if wanted), the airflow of the case and how modular some of these cases can be (removable hd cages or ssd caddy in back). Also when discussing the pros/cons of air vs liquid cooling, it is worth mentioning that the only thing likely to fail on air-cooling is the fan which is easily replaceable (and cheaper).
