1
00:00:00,719 --> 00:00:05,640
this is the Corsair ax850 I've had a lot

2
00:00:03,840 --> 00:00:09,800
of requests to have a look at the ax Series so this is the 850 wat version

3
00:00:08,200 --> 00:00:13,920
from the ax series I'm actually going to check out the 750 as well as the 1200 so

4
00:00:12,320 --> 00:00:17,480
we can talk a little about about what the differences are between these three

5
00:00:15,360 --> 00:00:21,439
models but I haven't seen those ones yet so I won't be able to talk about any

6
00:00:19,119 --> 00:00:24,920
differences today so this is a high performance ATX power supply why thank

7
00:00:23,400 --> 00:00:29,400
you Corsair thank you for telling me that that is so incredibly helpful

8
00:00:27,320 --> 00:00:34,600
what's high performance about it is this is the one one of the most efficient

9
00:00:31,720 --> 00:00:39,800
power supplies on the market this is 80 plus gold okay so that means that it

10
00:00:37,440 --> 00:00:46,399
achieves basically 80 plus gold is almost like 90 plus um because at about

11
00:00:44,000 --> 00:00:51,039
a 50% load which realistically if you're running like a pretty high-end gaming

12
00:00:48,039 --> 00:00:52,280
machine a couple GTX 460s a quad core

13
00:00:51,039 --> 00:00:57,399
that's about what you're going to see you're going to run even at 120 volt AC

14
00:00:55,239 --> 00:01:01,359
you're going to run at almost 90% efficiency okay so okay I exaggerated a

15
00:00:59,719 --> 00:01:05,920
little bit it's not 90 plus but the way 80 plus is measured is that it has to

16
00:01:03,640 --> 00:01:12,920
achieve at least I believe this one is 88 to 89% for 80 plus gold at uh very

17
00:01:10,600 --> 00:01:16,840
low load very high load as well as at medium load so that's pretty cool all

18
00:01:15,320 --> 00:01:21,000
right so here on the back they also talk a little bit about what connectors it

19
00:01:18,720 --> 00:01:25,840
has they talk about the true modular cabling system so all cable cables are

20
00:01:23,799 --> 00:01:30,479
detachable from the power supply now whereas Corsair's power supplies used to

21
00:01:27,920 --> 00:01:36,360
have hardwired 24 pin as as well as I believe EPS pin EPS pin EPS

22
00:01:34,040 --> 00:01:40,840
connectors incredible efficiency so yeah with 90% efficiency and they're talking

23
00:01:38,200 --> 00:01:44,560
about 220 volt for the most part there uh which most people in North America

24
00:01:42,640 --> 00:01:48,640
are not running so the course are Advantage with more than 15 years

25
00:01:46,680 --> 00:01:52,880
experience okay and then the last thing we should probably also say before we

26
00:01:50,159 --> 00:01:59,600
even open the box is it comes with a 7year warranty so Corsair's warranty

27
00:01:56,159 --> 00:02:01,520
service is legendary and with a 7year

28
00:01:59,600 --> 00:02:07,000
with 7 years of coverage from their warranty service you can pretty much

29
00:02:03,159 --> 00:02:08,640
rest assured that if anything goes wrong

30
00:02:07,000 --> 00:02:13,800
they will replace it for you they will get you taken care of and you will be a

31
00:02:11,039 --> 00:02:17,480
happy Corsair customer I've actually personally ARM made something from

32
00:02:15,360 --> 00:02:22,760
Corsair I don't remember what it was but I remember just they got back to me

33
00:02:19,080 --> 00:02:24,680
really fast and uh yeah I think the best

34
00:02:22,760 --> 00:02:28,160
RMA experiences are the ones that you don't really remember because that means

35
00:02:26,599 --> 00:02:32,760
that something went right and nothing went wrong okay so industry leading

36
00:02:31,080 --> 00:02:36,720
protection oh yeah they've got an eup logo on here as well so that's that new

37
00:02:35,080 --> 00:02:40,920
uh that new green thing I don't remember exactly what the requirements are but

38
00:02:38,360 --> 00:02:44,000
it's on there so it uses a different kind of box from Corsair's previous

39
00:02:42,519 --> 00:02:49,239
power supplies you can see we've got a sleeve here and then we have their more

40
00:02:46,640 --> 00:02:54,040
traditional box shape underneath which is sealed again look at that so I get to

41
00:02:51,280 --> 00:02:58,080
unbox more things in this particular episode look at that break more seals I

42
00:02:56,879 --> 00:03:01,920
do like breaking seals I'm not clubbing seals not all

43
00:03:00,480 --> 00:03:07,360
Canadians are into that okay so here is our manual it is in

44
00:03:06,000 --> 00:03:11,159
English France and that pretty much covers all

45
00:03:09,640 --> 00:03:16,560
the ones that I sort of remotely even know how to say maybe a cameraman can

46
00:03:13,360 --> 00:03:20,239
contribute this one for us RI ah there

47
00:03:16,560 --> 00:03:23,239
we go all right next we have the power

48
00:03:20,239 --> 00:03:26,680
cord and Corsair is using a nice quality

49
00:03:23,239 --> 00:03:30,080
flexible power cord with uh let's see

50
00:03:26,680 --> 00:03:33,080
maybe we can even say what the uh no

51
00:03:30,080 --> 00:03:35,120
never mind anyway it's thick there enjoy

52
00:03:33,080 --> 00:03:40,239
that knowledge all right next we have some cable ties as well as a Corsair

53
00:03:37,120 --> 00:03:42,480
case badge we also find four black

54
00:03:40,239 --> 00:03:46,200
screws so if you want to make sure that the back of your case has black screws

55
00:03:44,200 --> 00:03:52,319
holding in the power supply instead of mismatch silver screws then use that and

56
00:03:49,519 --> 00:03:56,239
that will be good okay let's have a look at the power supply itself and then

57
00:03:54,360 --> 00:04:00,959
we'll look at the modular cables so it comes in a nice little baggie here which

58
00:03:58,840 --> 00:04:04,439
you could use to store your gym strip if you're in high school and you still need

59
00:04:02,720 --> 00:04:08,400
a little bag for your gym strip so you could carry it to school in your Corsair

60
00:04:06,120 --> 00:04:13,280
bag and then you'd be the top of the town because realistically once you

61
00:04:11,200 --> 00:04:17,320
unplug this power or once you open up this power supply you're pretty much

62
00:04:14,519 --> 00:04:21,759
going to use it forever because it's pretty darn good okay wow it's actually

63
00:04:19,519 --> 00:04:26,520
surprisingly small for an 850 W unit so they have a 120 mil fan and you can see

64
00:04:24,080 --> 00:04:31,520
that even with only a 120 mil fan it's not a particularly long power supply I

65
00:04:28,759 --> 00:04:34,840
was actually expecting for an 80 plus uh power supply that it would be a little

66
00:04:33,120 --> 00:04:40,440
bit longer because with the well-built quality units unless they're using even

67
00:04:37,720 --> 00:04:44,000
more well-built even higher quality uh components you tend to see them a little

68
00:04:42,240 --> 00:04:48,560
bit bigger to make room for all of the extra uh extra junk inside so here if we

69
00:04:47,240 --> 00:04:52,960
look inside you can see the heat sinks are actually quite small and that's a

70
00:04:50,440 --> 00:04:56,360
product of this being um a very very efficient power supply you don't have a

71
00:04:54,400 --> 00:05:01,120
whole lot of excess heat to get rid of when you're running with it running with

72
00:04:58,919 --> 00:05:04,360
it I meant running it I didn't mean running

73
00:05:02,800 --> 00:05:06,880
with it all right let's have a look at the modular cables that we have included

74
00:05:06,080 --> 00:05:12,280
here so actually no let's finish looking at the power supply change my mind okay so

75
00:05:10,560 --> 00:05:16,160
here we've got our 120 mm fan as I mentioned before we've got our kind of

76
00:05:14,080 --> 00:05:21,600
pretty much industry standard honeycomb Grill on the back with an onoff switch

77
00:05:18,120 --> 00:05:23,800
and a power plug then on the top oh yeah

78
00:05:21,600 --> 00:05:29,720
this is a single rail power supply check that out 70 amps on the single 12vt rail

79
00:05:26,880 --> 00:05:37,160
up to 840 Watts don't do that it doesn't Focus up to 840 WT on that single 12vt

80
00:05:34,039 --> 00:05:38,960
Rail and then uh I think that's pretty

81
00:05:37,160 --> 00:05:41,840
much the highlight of that label you can see there's a bit of a gold color scheme

82
00:05:40,440 --> 00:05:46,160
to the power supply which goes along with its 80 plus gold rating and then

83
00:05:44,080 --> 00:05:50,960
here is the modular interface so let's look at what we would potentially plug

84
00:05:47,840 --> 00:05:55,600
into this okay so this this plug says

85
00:05:50,960 --> 00:05:59,120
750 850 ax only so only plug it into

86
00:05:55,600 --> 00:06:00,440
this so it goes wow 10 10 plugs that's

87
00:05:59,120 --> 00:06:05,280
kind of interesting I wonder why they've gone and done that so it goes where I

88
00:06:02,880 --> 00:06:09,479
don't know where it goes It goes here okay so it looks like we have two plugs

89
00:06:07,000 --> 00:06:13,120
for either 4 plus4 or eight sorry about that my memory card filled up is which

90
00:06:11,360 --> 00:06:18,720
happens a fair bit okay so you can plug in up to two uh 4 plus 4 or 8 Pin uh EPS

91
00:06:17,039 --> 00:06:23,120
connectors so you can see that's what these two right here are for and then

92
00:06:21,240 --> 00:06:26,880
wow there's so many cables in here I mean look at this this is like

93
00:06:25,080 --> 00:06:31,720
ridiculous okay so I'll go through and I'll find everything that is relevant so

94
00:06:29,280 --> 00:06:42,240
here we have this is two 6 plus2 pin PCIe so these ones plug in

95
00:06:34,680 --> 00:06:42,240
here presumably somewhere here no here

96
00:06:43,280 --> 00:06:50,680
no okay yeah okay so you can plug in two

97
00:06:47,520 --> 00:06:52,000
6 plus 2 pin PCIe or you can plug in EPS

98
00:06:50,680 --> 00:06:58,520
connectors here okay and then you can also plug in

99
00:06:56,000 --> 00:07:03,520
6 Plus TW pin connectors

100
00:07:00,560 --> 00:07:11,520
here no wow this is one of the more complicated modular interfaces I've seen

101
00:07:06,879 --> 00:07:14,120
to be uh to be perfectly honest because

102
00:07:11,520 --> 00:07:20,360
I don't actually see how to plug in oh I guess you I guess you can't I

103
00:07:18,000 --> 00:07:27,360
guess you can can't plug in oh wait here we go oh I get it okay here so here we

104
00:07:24,280 --> 00:07:30,080
are this is a 4 plus4 or 8 pin connector

105
00:07:27,360 --> 00:07:41,520
and this one goes here so then then you can either plug in two 6 + 2's * 2 so up

106
00:07:36,400 --> 00:07:45,599
to 4 6 plus2 pin PCIe connectors or you

107
00:07:41,520 --> 00:07:48,720
can plug in two 6 plus2 PCIe connectors

108
00:07:45,599 --> 00:07:50,759
and an additional 4 plus4 so if you have

109
00:07:48,720 --> 00:07:55,400
a board like a rampage 3 Extreme that takes two 8 Pin CPU connectors then you

110
00:07:53,599 --> 00:08:00,199
can plug those in but then you can only run one high powerered graphics card or

111
00:07:57,800 --> 00:08:05,240
you can plug in only one and you can run two high powerered graphics cards yes we

112
00:08:02,759 --> 00:08:09,240
figured it out excellent so then here's some Molex ones each of these has four

113
00:08:07,039 --> 00:08:13,960
molexes on it and that's pretty much the whole top row of connectors here so this

114
00:08:11,240 --> 00:08:19,639
is for Mox and SATA 1 2 3 4 five of those all right so let's uh go through

115
00:08:17,720 --> 00:08:25,319
here and see how many of those we have so this is four SATA this one is four

116
00:08:22,319 --> 00:08:27,319
SATA uh this one is uh oh yeah four pin

117
00:08:25,319 --> 00:08:30,280
Molex to Floppy adapter because really most people don't use those anymore

118
00:08:28,720 --> 00:08:35,159
here's two s and here is another Molex to Floppy just

119
00:08:33,039 --> 00:08:41,839
in case you're running uh Crossfire radon 9700 pros and then we've got a

120
00:08:39,200 --> 00:08:46,760
another dual SATA so you could potentially Run 4 + 4 is 8 so 12 SATA

121
00:08:44,880 --> 00:08:52,200
connections off here and then like four Mo X's uh and then last but not least we

122
00:08:50,560 --> 00:08:56,399
have the 24 pin connector which is broken up into two pieces so you

123
00:08:54,320 --> 00:09:00,839
actually plug that in with one here at the bottom so that's with that last uh

124
00:08:58,760 --> 00:09:05,959
last rank on the the bottom was four and then one here at the top and that is

125
00:09:04,399 --> 00:09:12,320
your 24 pin connector thank you for checking out our very confusing unboxing

126
00:09:09,040 --> 00:09:15,600
