the computer power supply it's almost as
mysterious as the phrase i'm fine just leave me alone
i mean what does that even mean if i actually leave you alone to go play
video games will i be making a huge mistake and will i pay for it later i
mean if you were fine wouldn't you want to talk to me like you normally do and
if you're not fine when it blows up later will it be your fault for not
communicating clearly or my fault for not understanding please just tell me
what you want anyway so while i'm not qualified to help you understand women i
can help you choose the right wattage power supply for your pc step one is
finding out how much power you actually need for the components inside your pc
this is expressed in the total number of watts that the unit is capable of
outputting and the best way to find all that out is to head over to
coolermaster.outervision.com it's linked in the video description and
enter the stuff you're using or plan to use it's that simple if you run into
anything confusing just post it in the linustechtips.com forum under power
supplies and our awesome community will help you out now that calculator does
add a bit of fudge factor for stuff like the aging of your components over time
so it might err on the side of a little bit too much but it's best not to try to
squeeze under that and use something insufficient that can result in
unexpected shutdowns and wear and tear over time now
some people will naturally go completely the other way and see 400 watts in the
calculator and figure well to be safe i'll just grab a 1200 watt power supply
but that's not necessarily right either first your wallet will be more empty
than it had to be and second your system efficiency will actually be lower than
if you bought something more appropriate a power supply operates optimally above
about 15 to 25 percent of its total capacity that means that your system
will actually draw more power from the wall than it has to and your power bill
will cost a bit more sounds terrible right well
sometimes it makes sense i'm one of those people who went overkill on my
power supply but it's because it has a fanless
zero decibel mode for completely silent operation when i'm not fully utilizing
my pc an example of this is cooler master silent pro hybrid series which
doesn't even turn on the fan until it reaches 200 watts of load so you can
trade a bit of efficiency for quiet if you're into that step two is finding a
power supply that matches the wattage your calculator spat out there are two
ways that the capability of a power supply can be expressed as peak wattage
or continuous wattage now i have a hint for cutting through the bs here if a
power supply is rated in continuous then that's good if it's rated in continuous
with a separate peak rating then that's good too if it only has a peak rating
then don't put it anywhere near your system because there's no real standard
for what peak means can it handle that for an hour a minute a week a split
second before it goes nuclear we don't know if a power supply is rated only in
peak wattage but not continuous don't even consider buying it which leads us
to the final step picking a power supply of sufficient quality it's important and
this isn't one of those used car salesmen moments here guys i get asked
all the time why i don't review the latest power supply with 100
multi-colored leds in an acrylic case from jack tech and the answer is that i
don't care about it at all a power supply is a serious piece of equipment
not a fashion statement and unless it's from a trusted manufacturer with all the
appropriate safety certifications and or gets a seal of approval from johnny guru
or a similarly reputable power supply review site i'm not going to touch it a
power supply can fail spectacularly triggering the premature or even
immediate failure of other components in your system and your warranty will not
cover you being a doofus and relying on a potato to provide safe stable power to
your pc and that's not even the worst case scenario a fire caused by a power
supply can burn down your house on that somber note our sponsor for this episode
is cooler master and the only power supply brand you should ever consider
buying is cooler master because i'm just messing with you guys cooler
master would have to pay me a lot more than they are to pretend that they're the only solid power supply brand that
exists in all seriousness though this video was
brought to you by cooler master and they are one of the solid power supply makers
with options ranging from uh value-oriented solutions like the gn
series all the way up to the v series which includes modular cabling extremely
low ripple and uses only high quality japanese capacitors and
i think we're done here if you guys enjoyed this video and you're shopping
