00:00:00.040 --> 00:00:06.040
High wattage power supplies are almost always a bad idea just due to being too

00:00:03.959 --> 00:00:10.240
expensive I mean sure that is of course as long as you're not doing some asinine

00:00:08.280 --> 00:00:15.599
projects such as seven Gamers or eight Gamers or 10 gamers one CPU and even

00:00:13.759 --> 00:00:21.840
then running seven freaking graphics cards two 140 wat TDP CPUs and a small

00:00:18.960 --> 00:00:26.350
mountain of ssds does legitimately take some solid wattage your standard gaming

00:00:24.080 --> 00:00:35.000
PC does not

tunnel bear is the simple VPN app that makes it easy to browse privately and

00:00:38.960 --> 00:00:44.800
enjoy a more open internet to try tunnel bear for free check out the link in the

00:00:42.800 --> 00:00:49.039
video description we have a number of videos about not needing super high

00:00:46.360 --> 00:00:53.480
wattage power supplies but it became even more blatantly apparent when our

00:00:51.000 --> 00:01:00.359
massively Overkill setup of a high-end enthusias 6850k and dual GTX 1080s Drew

00:00:57.800 --> 00:01:07.200
just over a third of the watted dwell under heavy load of a standard Flagship

00:01:03.719 --> 00:01:09.119
power supply at 1200 WTS what the SH now

00:01:07.200 --> 00:01:13.320
I know I know this isn't a new idea as I already said and I do have a fairly

00:01:11.119 --> 00:01:17.119
recent video on it a super craptastic Workshop video that you actually

00:01:15.119 --> 00:01:22.200
probably shouldn't bother watching because well it's garbage but be quiet!'s

00:01:19.960 --> 00:01:28.079
own Kristoff katzer has an article on this back from 2008 when he used to work

00:01:25.119 --> 00:01:32.200
with an nanch which is named debunking power supply myths and is actually a

00:01:30.200 --> 00:01:38.320
wonderful read in his final thoughts section he notes that few people if any

00:01:35.360 --> 00:01:43.000
need more than an 850 W power supply that's from 2008 components have been

00:01:40.840 --> 00:01:47.439
getting progressively more and more efficient this entire time and it

00:01:45.399 --> 00:01:51.920
doesn't stop there either power supplies have also been getting more efficient as

00:01:49.479 --> 00:01:56.320
well with the increasing abundance of highly rated 80 plus versions across the

00:01:54.439 --> 00:01:59.920
board recommended power supply ratings for various computer components have

00:01:58.240 --> 00:02:05.680
started to react to this as well which which is great for example Zac's crazy

00:02:02.799 --> 00:02:11.360
new amp extreme GTX 1080 featuring an oversized 2 and 1 half slot cooler and

00:02:09.080 --> 00:02:16.519
ample amounts of power sorry terrible joke it only recommends a 500 wat power

00:02:13.879 --> 00:02:22.200
supply for the whole system and cooler Master's power supply calculator seems

00:02:18.360 --> 00:02:25.760
to sing a similar tune an i56600k with

00:02:22.200 --> 00:02:29.319
16 gigs of RAM a GTX 1070 an SSD a hard

00:02:25.760 --> 00:02:31.879
drive a few USB devices a 240 mm

00:02:29.319 --> 00:02:38.480
allinone CPU Cooler additional three fans and gaming peripherals all equated

00:02:34.480 --> 00:02:40.519
to an estimated grand total of 344 Watts

00:02:38.480 --> 00:02:45.480
at load and a recommended power supply of 394 Watts but as I'm sure a few of

00:02:43.319 --> 00:02:49.879
you are acutely aware this isn't the whole story and I wouldn't buy a 400 W

00:02:47.560 --> 00:02:53.760
power supp for that computer any day I just wouldn't really be comfortable with

00:02:51.319 --> 00:02:59.280
that not only do the capacitors within a power supply degrade slightly over time

00:02:57.000 --> 00:03:03.480
as it ages but there is also the efficiency curve to consider and the

00:03:01.959 --> 00:03:07.560
overall build quality of the power supply each power Supply's efficiency

00:03:05.360 --> 00:03:13.000
curve is more or less unique but let's use the curve of the Corsair 1200i for

00:03:10.319 --> 00:03:17.599
example you can easily see the rise and the fall best in the middle worst at

00:03:15.280 --> 00:03:22.000
excessively high and excessively low usages ideally if your power bills are

00:03:20.159 --> 00:03:26.680
high you'd like to sit the load power of your system at a highly efficient point

00:03:24.480 --> 00:03:30.480
in this curve as long as that makes sense to offset the cost of the power

00:03:28.200 --> 00:03:34.120
supply for that particular purpose another graph supplied by Corsair and

00:03:32.319 --> 00:03:38.400
the reason I chose this power supply as the example is the fan noise graph

00:03:36.640 --> 00:03:42.720
people going for absolutely silent systems can greatly benefit from low

00:03:40.879 --> 00:03:48.680
power usage components because certain power supplies are able to go into a

00:03:45.200 --> 00:03:52.239
zero RPM fan mode below certain amounts

00:03:48.680 --> 00:03:56.200
of wattage or usage at 30% a 1200i would

00:03:52.239 --> 00:03:59.239
give you 360 watts of zero RPM fan mode

00:03:56.200 --> 00:04:01.720
head room plenty enough for a 6850k and

00:03:59.239 --> 00:04:07.000
a GTX x 1080 which is a really high-end setup but don't use this video as an

00:04:04.360 --> 00:04:11.680
excuse to buy a cheap crappy power supply buy a good power supply skimping

00:04:09.319 --> 00:04:16.600
on this component is just fundamentally a bad idea that being said buying a 1200

00:04:14.799 --> 00:04:22.280
watt power supply for your system when it will only Peak at like 300 watts and

00:04:19.759 --> 00:04:26.320
you don't care about zero RPM mode is just lighting your money on fire there's

00:04:24.280 --> 00:04:31.479
no point in doing that if you're worried about your choice of power supply check

00:04:28.440 --> 00:04:32.720
out Johnny Guru power Supply reviews I'm

00:04:31.479 --> 00:04:39.039
pretty sure he's been reviewing power supplies for longer than I've been interested in computers in total and

00:04:37.199 --> 00:04:43.759
that guy knows a lot all right guys if you disliked the video because you're

00:04:40.720 --> 00:04:45.199
like I knew all that already hit the

00:04:43.759 --> 00:04:50.880
dislike button hit the like button if you liked it and feel free to get subscribed check out power supplies at

00:04:48.800 --> 00:04:54.919
Amazon and also Link in the video description is our merch store which I

00:04:52.880 --> 00:04:58.880
think will soon have these shirts I'm not entirely sure and the Forum

00:04:56.800 --> 00:05:02.240
Community where it's you can discuss things like

00:05:00.160 --> 00:05:06.160
the intricate qualities of power supply components as you read them on Johnny

00:05:03.919 --> 00:05:10.520
Guru because I'm not going to get into that type of power supply review nope

00:05:08.440 --> 00:05:15.919
not happening check out this video whoever is editing this will pick

00:05:13.639 --> 00:05:19.520
their favorite video on any one of our three channels actually no pick a tech

00:05:17.639 --> 00:05:23.880
quickie video because I'm wearing the shirt there we go
