1
00:00:00,080 --> 00:00:05,359
power supplies haven't changed that much over the years but there's a new

2
00:00:03,600 --> 00:00:10,400
specification that could force you to buy a new one the next time you upgrade

3
00:00:07,040 --> 00:00:13,040
your GPU it's called atx 3.0 and it was

4
00:00:10,400 --> 00:00:17,119
designed by Intel specifically with high performance gpus in mind but what's

5
00:00:15,200 --> 00:00:21,199
different about it let's start by talking about the most obvious part of

6
00:00:18,880 --> 00:00:24,720
the new spec the power connector for your GPU

7
00:00:22,560 --> 00:00:30,320
instead of the 8-pin pci express connector that we've been used to for a

8
00:00:26,320 --> 00:00:32,600
long time atx 3.0 uses a 16-pin

9
00:00:30,320 --> 00:00:38,399
connector called 12vhpwr which is a mouthful that stands

10
00:00:35,440 --> 00:00:42,800
for 12 volts high power any power supply rated for more than 450

11
00:00:40,960 --> 00:00:46,960
watts is supposed to use this new connector which is meant to simplify the

12
00:00:44,719 --> 00:00:51,600
build process instead of having different graphics cards requiring

13
00:00:48,879 --> 00:00:56,800
different numbers of six or eight pin connectors or even custom ones new cards

14
00:00:54,399 --> 00:01:00,879
would instead just need one of these new 16 16-pin connectors

15
00:00:58,399 --> 00:01:05,920
even if a particular card is on the more power-hungry side think of it kind of

16
00:01:02,879 --> 00:01:08,000
like usb-c and that it's one form factor

17
00:01:05,920 --> 00:01:11,920
to plug in but with different power delivery depending on the implementation

18
00:01:10,320 --> 00:01:19,680
the spec recommends that the connector be labeled with how much power it

19
00:01:13,680 --> 00:01:22,159
supports 150 300 450 or 600 watts though

20
00:01:19,680 --> 00:01:25,520
that 600 watt option is supposed to only be used for liquid cooled cards since

21
00:01:24,320 --> 00:01:30,320
that's just wow a lot of power

22
00:01:27,680 --> 00:01:34,000
and remember how i said it had 16 pins well four of those pins are smaller than

23
00:01:32,400 --> 00:01:38,960
the rest and they're there so that the power supply and the GPU can actually

24
00:01:36,799 --> 00:01:43,439
talk to each other specifically the power supply can tell the GPU what its

25
00:01:41,360 --> 00:01:47,680
capabilities are which means that if you have a beefy graphics card but a power

26
00:01:45,840 --> 00:01:52,640
supply that can't quite provide all the power it might ask for the power supply

27
00:01:49,759 --> 00:01:57,360
can tell the GPU hey i'm not actually that powerful and the GPU's power limit

28
00:01:54,960 --> 00:02:00,960
can be lowered to accommodate it this should help prevent unexpected

29
00:01:58,880 --> 00:02:04,880
instability due to a card drawing too much power though it also means that

30
00:02:03,280 --> 00:02:09,280
your GPU's performance could be throttled if your power supply isn't up

31
00:02:06,880 --> 00:02:13,599
to scratch so you'll need to make sure that your power supply is rated for the

32
00:02:11,039 --> 00:02:18,319
amount of power that your GPU requires oh and also the rest of your system

33
00:02:15,599 --> 00:02:22,080
however the 16-pin plug isn't the only thing they've changed and we'll tell you

34
00:02:19,760 --> 00:02:27,200
about the other key features of atx 3.0 after we thank our sponsor see sonic how

35
00:02:24,000 --> 00:02:29,760
appropriate seasonic's focus plus 750

36
00:02:27,200 --> 00:02:34,080
watt gold power supply is a great choice for mid-range systems at a great price

37
00:02:32,080 --> 00:02:39,200
it features an 80 plus gold efficiency rating is fully modular comes with fluid

38
00:02:36,560 --> 00:02:43,519
dynamic fan bearings and has hybrid fan control to limit noise it's all backed

39
00:02:41,280 --> 00:02:47,680
by their 10 year warranty so why wait learn more at seasonic.com or through

40
00:02:45,760 --> 00:02:53,680
the links down below one of the other new atx 3.0 features also aimed at gpus

41
00:02:50,800 --> 00:02:58,800
is better spike resistance the thing is gpus have a normal power draw when

42
00:02:56,560 --> 00:03:03,680
they're under load like playing a game but they can also experience big

43
00:03:01,200 --> 00:03:09,599
momentary spikes in power draw this is a notable issue with rtx 3000 series cards

44
00:03:06,959 --> 00:03:15,280
well atx 3.0 is supposed to alleviate this by requiring any certified power

45
00:03:12,000 --> 00:03:18,239
supply to be capable of providing twice

46
00:03:15,280 --> 00:03:22,239
its maximum rated power for 10 straight microseconds and it has to be able to do

47
00:03:20,560 --> 00:03:26,800
this for 10 of its total running time that means

48
00:03:24,319 --> 00:03:31,200
that power supplies may become costlier due to the better electronics required

49
00:03:28,959 --> 00:03:35,440
don't have a high-end GPU join the club well there are other

50
00:03:32,879 --> 00:03:39,440
changes that still might affect you atx 3.0 should deliver better longevity with

51
00:03:37,760 --> 00:03:44,959
power supplies being able to handle over 175 000 power cycles per year which is

52
00:03:43,040 --> 00:03:51,280
kind of like turning your computer off and back on 480 times a day over its

53
00:03:48,080 --> 00:03:53,120
lifetime and speaking of which atx 3.0

54
00:03:51,280 --> 00:03:57,760
should provide faster system wake up time so i say go for it turn it on and

55
00:03:55,920 --> 00:04:01,120
off as often as you want efficiency should also improve when your

56
00:03:59,519 --> 00:04:06,400
system isn't working too hard as power supplies have to be above sixty percent

57
00:04:03,040 --> 00:04:08,799
efficient at just 10 watts or at two

58
00:04:06,400 --> 00:04:12,560
percent of their rated maximum power the spec also mentions that there will

59
00:04:10,560 --> 00:04:17,680
be a new certification system from cybernetic Labs this is kind of like the

60
00:04:15,599 --> 00:04:22,400
80 plus system that we're all used to but cybernetics raises power supplies

61
00:04:19,759 --> 00:04:26,800
for both noise and efficiency so you should be able to get a quick idea as to

62
00:04:24,320 --> 00:04:30,960
how loud your new psu will be just by looking at the box so should you budget

63
00:04:29,360 --> 00:04:35,440
for a new power supply alongside your next GPU purchase

64
00:04:32,720 --> 00:04:39,840
ah well remember that this is a recently published spec and it may be quite a

65
00:04:37,520 --> 00:04:44,960
while before atx 3.0 power supplies hit the market if we end up seeing them at

66
00:04:42,080 --> 00:04:48,639
all Intel is pushing the spec but it could meet resistance from manufacturers

67
00:04:46,880 --> 00:04:53,440
if the changes end up being too costly to implement so don't go throwing out

68
00:04:50,960 --> 00:04:55,840
your existing power supply just yet i mean

69
00:04:54,240 --> 00:05:00,080
it works pretty hard for you and when's the last time you even told it thank you

70
00:04:58,639 --> 00:05:05,600
and when's the last time you hit the like button and subscribed

71
00:05:01,840 --> 00:05:05,600
hopefully just moments ago
