High wattage power supplies are almost always a bad idea just due to being too
expensive I mean sure that is of course as long as you're not doing some asinine
projects such as seven Gamers or eight Gamers or 10 gamers one CPU and even
then running seven freaking graphics cards two 140 wat TDP CPUs and a small
mountain of ssds does legitimately take some solid wattage your standard gaming
PC does not

video description we have a number of videos about not needing super high
wattage power supplies but it became even more blatantly apparent when our
massively Overkill setup of a high-end enthusias 6850k and dual GTX 1080s Drew
just over a third of the watted dwell under heavy load of a standard Flagship
power supply at 1200 WTS what the SH now
I know I know this isn't a new idea as I already said and I do have a fairly
recent video on it a super craptastic Workshop video that you actually
probably shouldn't bother watching because well it's garbage but be quiet!'s
own Kristoff katzer has an article on this back from 2008 when he used to work
with an nanch which is named debunking power supply myths and is actually a
wonderful read in his final thoughts section he notes that few people if any
need more than an 850 W power supply that's from 2008 components have been
getting progressively more and more efficient this entire time and it
doesn't stop there either power supplies have also been getting more efficient as
well with the increasing abundance of highly rated 80 plus versions across the
board recommended power supply ratings for various computer components have
started to react to this as well which which is great for example Zac's crazy
new amp extreme GTX 1080 featuring an oversized 2 and 1 half slot cooler and
ample amounts of power sorry terrible joke it only recommends a 500 wat power
supply for the whole system and cooler Master's power supply calculator seems
to sing a similar tune an i56600k with
16 gigs of RAM a GTX 1070 an SSD a hard
drive a few USB devices a 240 mm
allinone CPU Cooler additional three fans and gaming peripherals all equated
to an estimated grand total of 344 Watts
at load and a recommended power supply of 394 Watts but as I'm sure a few of
you are acutely aware this isn't the whole story and I wouldn't buy a 400 W
power supp for that computer any day I just wouldn't really be comfortable with
that not only do the capacitors within a power supply degrade slightly over time
as it ages but there is also the efficiency curve to consider and the
overall build quality of the power supply each power Supply's efficiency
curve is more or less unique but let's use the curve of the Corsair 1200i for
example you can easily see the rise and the fall best in the middle worst at
excessively high and excessively low usages ideally if your power bills are
high you'd like to sit the load power of your system at a highly efficient point
in this curve as long as that makes sense to offset the cost of the power
supply for that particular purpose another graph supplied by Corsair and
the reason I chose this power supply as the example is the fan noise graph
people going for absolutely silent systems can greatly benefit from low
power usage components because certain power supplies are able to go into a
zero RPM fan mode below certain amounts
of wattage or usage at 30% a 1200i would
give you 360 watts of zero RPM fan mode
head room plenty enough for a 6850k and
a GTX x 1080 which is a really high-end setup but don't use this video as an
excuse to buy a cheap crappy power supply buy a good power supply skimping
on this component is just fundamentally a bad idea that being said buying a 1200
watt power supply for your system when it will only Peak at like 300 watts and
you don't care about zero RPM mode is just lighting your money on fire there's
no point in doing that if you're worried about your choice of power supply check
out Johnny Guru power Supply reviews I'm
pretty sure he's been reviewing power supplies for longer than I've been interested in computers in total and
that guy knows a lot all right guys if you disliked the video because you're
like I knew all that already hit the
dislike button hit the like button if you liked it and feel free to get subscribed check out power supplies at
Amazon and also Link in the video description is our merch store which I
think will soon have these shirts I'm not entirely sure and the Forum
Community where it's you can discuss things like
the intricate qualities of power supply components as you read them on Johnny
Guru because I'm not going to get into that type of power supply review nope
not happening check out this video whoever is editing this will pick
their favorite video on any one of our three channels actually no pick a tech
quickie video because I'm wearing the shirt there we go
