1
00:00:00,080 --> 00:00:06,080
the computer power supply it's almost as

2
00:00:03,120 --> 00:00:09,200
mysterious as the phrase i'm fine just leave me alone

3
00:00:07,520 --> 00:00:12,480
i mean what does that even mean if i actually leave you alone to go play

4
00:00:10,800 --> 00:00:15,920
video games will i be making a huge mistake and will i pay for it later i

5
00:00:14,320 --> 00:00:19,760
mean if you were fine wouldn't you want to talk to me like you normally do and

6
00:00:17,920 --> 00:00:22,880
if you're not fine when it blows up later will it be your fault for not

7
00:00:21,199 --> 00:00:27,920
communicating clearly or my fault for not understanding please just tell me

8
00:00:24,960 --> 00:00:31,840
what you want anyway so while i'm not qualified to help you understand women i

9
00:00:30,080 --> 00:00:36,960
can help you choose the right wattage power supply for your pc step one is

10
00:00:34,800 --> 00:00:41,840
finding out how much power you actually need for the components inside your pc

11
00:00:39,440 --> 00:00:46,399
this is expressed in the total number of watts that the unit is capable of

12
00:00:44,160 --> 00:00:50,000
outputting and the best way to find all that out is to head over to

13
00:00:47,680 --> 00:00:54,320
coolermaster.outervision.com it's linked in the video description and

14
00:00:51,840 --> 00:00:59,160
enter the stuff you're using or plan to use it's that simple if you run into

15
00:00:57,039 --> 00:01:03,120
anything confusing just post it in the linustechtips.com forum under power

16
00:01:01,039 --> 00:01:08,400
supplies and our awesome community will help you out now that calculator does

17
00:01:06,080 --> 00:01:13,040
add a bit of fudge factor for stuff like the aging of your components over time

18
00:01:10,799 --> 00:01:17,920
so it might err on the side of a little bit too much but it's best not to try to

19
00:01:16,080 --> 00:01:22,880
squeeze under that and use something insufficient that can result in

20
00:01:20,159 --> 00:01:26,640
unexpected shutdowns and wear and tear over time now

21
00:01:24,720 --> 00:01:31,200
some people will naturally go completely the other way and see 400 watts in the

22
00:01:29,119 --> 00:01:36,400
calculator and figure well to be safe i'll just grab a 1200 watt power supply

23
00:01:33,920 --> 00:01:40,960
but that's not necessarily right either first your wallet will be more empty

24
00:01:38,400 --> 00:01:45,360
than it had to be and second your system efficiency will actually be lower than

25
00:01:43,600 --> 00:01:51,920
if you bought something more appropriate a power supply operates optimally above

26
00:01:49,280 --> 00:01:55,920
about 15 to 25 percent of its total capacity that means that your system

27
00:01:54,079 --> 00:02:00,560
will actually draw more power from the wall than it has to and your power bill

28
00:01:58,240 --> 00:02:04,799
will cost a bit more sounds terrible right well

29
00:02:01,920 --> 00:02:08,560
sometimes it makes sense i'm one of those people who went overkill on my

30
00:02:06,719 --> 00:02:14,160
power supply but it's because it has a fanless

31
00:02:11,200 --> 00:02:18,560
zero decibel mode for completely silent operation when i'm not fully utilizing

32
00:02:16,000 --> 00:02:22,800
my pc an example of this is cooler master silent pro hybrid series which

33
00:02:21,040 --> 00:02:27,760
doesn't even turn on the fan until it reaches 200 watts of load so you can

34
00:02:25,040 --> 00:02:31,920
trade a bit of efficiency for quiet if you're into that step two is finding a

35
00:02:30,080 --> 00:02:35,760
power supply that matches the wattage your calculator spat out there are two

36
00:02:33,920 --> 00:02:41,760
ways that the capability of a power supply can be expressed as peak wattage

37
00:02:38,800 --> 00:02:46,239
or continuous wattage now i have a hint for cutting through the bs here if a

38
00:02:43,519 --> 00:02:50,879
power supply is rated in continuous then that's good if it's rated in continuous

39
00:02:48,640 --> 00:02:56,080
with a separate peak rating then that's good too if it only has a peak rating

40
00:02:54,160 --> 00:03:00,400
then don't put it anywhere near your system because there's no real standard

41
00:02:58,160 --> 00:03:05,040
for what peak means can it handle that for an hour a minute a week a split

42
00:03:02,879 --> 00:03:08,959
second before it goes nuclear we don't know if a power supply is rated only in

43
00:03:07,440 --> 00:03:13,440
peak wattage but not continuous don't even consider buying it which leads us

44
00:03:11,120 --> 00:03:18,560
to the final step picking a power supply of sufficient quality it's important and

45
00:03:16,319 --> 00:03:23,040
this isn't one of those used car salesmen moments here guys i get asked

46
00:03:20,879 --> 00:03:27,040
all the time why i don't review the latest power supply with 100

47
00:03:24,800 --> 00:03:32,000
multi-colored leds in an acrylic case from jack tech and the answer is that i

48
00:03:29,760 --> 00:03:36,480
don't care about it at all a power supply is a serious piece of equipment

49
00:03:34,319 --> 00:03:41,360
not a fashion statement and unless it's from a trusted manufacturer with all the

50
00:03:38,640 --> 00:03:46,159
appropriate safety certifications and or gets a seal of approval from johnny guru

51
00:03:44,080 --> 00:03:51,280
or a similarly reputable power supply review site i'm not going to touch it a

52
00:03:48,480 --> 00:03:55,599
power supply can fail spectacularly triggering the premature or even

53
00:03:53,120 --> 00:04:00,239
immediate failure of other components in your system and your warranty will not

54
00:03:57,680 --> 00:04:04,799
cover you being a doofus and relying on a potato to provide safe stable power to

55
00:04:02,879 --> 00:04:09,680
your pc and that's not even the worst case scenario a fire caused by a power

56
00:04:07,120 --> 00:04:14,879
supply can burn down your house on that somber note our sponsor for this episode

57
00:04:11,920 --> 00:04:19,120
is cooler master and the only power supply brand you should ever consider

58
00:04:16,799 --> 00:04:22,560
buying is cooler master because i'm just messing with you guys cooler

59
00:04:21,040 --> 00:04:26,479
master would have to pay me a lot more than they are to pretend that they're the only solid power supply brand that

60
00:04:25,520 --> 00:04:30,320
exists in all seriousness though this video was

61
00:04:28,560 --> 00:04:34,720
brought to you by cooler master and they are one of the solid power supply makers

62
00:04:32,800 --> 00:04:38,960
with options ranging from uh value-oriented solutions like the gn

63
00:04:36,800 --> 00:04:43,600
series all the way up to the v series which includes modular cabling extremely

64
00:04:41,520 --> 00:04:47,919
low ripple and uses only high quality japanese capacitors and

65
00:04:46,160 --> 00:04:51,360
i think we're done here if you guys enjoyed this video and you're shopping

66
00:04:49,360 --> 00:04:54,720
for a power supply it is definitely worth checking out the sponsor link in

67
00:04:53,040 --> 00:04:58,000
the video description to see if they have anything that floats your boat
