learn more welcome to my unboxing and overview of what might be the most quiet

4
00:00:18,240 --> 00:00:24,519
optimized power supply that we've yet encountered this is the new RM series

5
00:00:22,640 --> 00:00:29,640
from Corsair and it's kind of a replacement for the

6
00:00:26,240 --> 00:00:32,239
txm V2 so that is their TX modular

7
00:00:29,640 --> 00:00:36,840
series so as you might expect it is a modular power supply which means the

8
00:00:33,840 --> 00:00:39,280
cables are not preattached and what you

9
00:00:36,840 --> 00:00:44,680
also might not expect is that it has what Corsair is calling their zero RPM

10
00:00:42,840 --> 00:00:50,280
fan mode so they've brought this down from the ax and axi series to the RM

11
00:00:47,399 --> 00:00:55,680
Series so your fan actually is not even going to spin up at all until you reach

12
00:00:53,039 --> 00:01:00,879
about 40% load so this is your typical power supply fan curve compared to their

13
00:00:58,160 --> 00:01:05,040
zero RPM fan curve now now with all of that said this isn't the first time

14
00:01:03,280 --> 00:01:09,320
we've ever seen this feature in fact it's been around for kind of a while the

15
00:01:06,920 --> 00:01:14,600
power supply in my system doesn't have its fan spin up until it's under a

16
00:01:12,040 --> 00:01:18,640
fairly significant load but it's the first time that we've seen a

17
00:01:16,119 --> 00:01:23,680
manufacturer optimized for silence in a way that goes beyond having the fan not

18
00:01:21,159 --> 00:01:28,119
spin so we've actually got a closed cell foam inside here for packaging and we're

19
00:01:25,759 --> 00:01:33,240
going to go ahead and open this baby up so what Corsair's done is they've

20
00:01:29,600 --> 00:01:34,960
optimized the fan blades on the 135 or

21
00:01:33,240 --> 00:01:39,159
140 mm fan whatever they're calling it they're usually around the same size to

22
00:01:36,920 --> 00:01:44,000
reduce turbulence okay so it's not the first time we've heard a manufacturer

23
00:01:40,520 --> 00:01:45,880
say yes optimized fan design okay uh but

24
00:01:44,000 --> 00:01:50,320
what they've really done is they have hand selected the components inside the

25
00:01:48,000 --> 00:01:54,920
power supply to not only not make noise with the actively moving stuff but to

26
00:01:52,360 --> 00:01:59,000
not make like weird electrical buzzing noises and whining noises which are

27
00:01:57,079 --> 00:02:02,520
often referred to as coil whne even though there's a wide variet of

28
00:02:00,200 --> 00:02:06,119
components inside electronic devices that can cause this kind of noise so

29
00:02:04,880 --> 00:02:11,000
that means and I don't know if you guys have ever seen this before but I certainly have I've seen fanless power

30
00:02:09,080 --> 00:02:16,200
supplies that make annoying noises in fact my power supply which is an XFX

31
00:02:13,239 --> 00:02:19,680
th000 watt Platinum has a ticking noise that is audible even when the Fan's not

32
00:02:17,959 --> 00:02:23,440
spinning at all but I personally appreciate this kind of an optimization

33
00:02:21,360 --> 00:02:27,080
and I'm excited to find out if it actually ends up working so let's take

34
00:02:25,800 --> 00:02:33,440
you guys on a bit of a tour of the product itself they've got a little warning sticker here that says yo the

35
00:02:30,319 --> 00:02:35,120
Fan's not spinning it's okay because

36
00:02:33,440 --> 00:02:38,640
it's designed to do that we've also got a nice open honeycomb mesh at the back

37
00:02:37,040 --> 00:02:41,560
and it otherwise looks pretty much like any other Corsair power supply they've

38
00:02:40,200 --> 00:02:45,519
got a bit of sort of rounded Corner thing going on and those RM logos on the

39
00:02:43,879 --> 00:02:49,080
side are right side up regardless of how you install it in your system on the

40
00:02:47,560 --> 00:02:55,120
front of the power supply or back or whatever you want to call this on this side you find the modular interface so

41
00:02:52,360 --> 00:03:00,599
your 24 pin cable goes here you have five spots for either 4 plus4 pin for

42
00:02:58,000 --> 00:03:05,000
your CPU or 6 plus2 pin for PCI Express so that's four total PCIe and one CPU

43
00:03:02,959 --> 00:03:09,080
connector five peripheral connectors and a Corsair link connector another thing

44
00:03:07,560 --> 00:03:14,840
that's a little bit unique and special about this power supply is the fully

45
00:03:11,319 --> 00:03:16,760
flat modular cables even the 24 pin is

46
00:03:14,840 --> 00:03:21,760
using a flat cable design that is extremely low profile I love this even

47
00:03:19,680 --> 00:03:28,760
going back to Corsair's original HX series power supplies they had the flat

48
00:03:24,200 --> 00:03:31,120
cables on Molex and SATA however this is

49
00:03:28,760 --> 00:03:38,000
the first time I personally seen the flat cable approach taken with 24 pin as

50
00:03:34,439 --> 00:03:39,840
well as with 6 plus2 see nice flat

51
00:03:38,000 --> 00:03:43,439
there's your eight wires and otherwise it's completely flat as well as the four

52
00:03:41,599 --> 00:03:47,519
plus4 pin this makes Cable Management easier even if you don't happen to have

53
00:03:45,519 --> 00:03:52,799
a case that's great for cable management so kudos to Corsair for thinking of that

54
00:03:50,720 --> 00:03:56,560
and implementing it because it's actually not that easy to get factories

55
00:03:54,560 --> 00:04:00,159
to do things like this there's a lot of um there's a lot of ease of assembly

56
00:03:58,439 --> 00:04:03,000
stuff that goes along with color coding things which is why they like to color

57
00:04:01,920 --> 00:04:10,200
code them at the factory and Manufacturing level so there's a little tidbit for you guys in terms of included

58
00:04:06,599 --> 00:04:12,159
connectors we've got two four pin Molex

59
00:04:10,200 --> 00:04:16,759
harnesses each with four connectors on them and then we have three SATA

60
00:04:14,439 --> 00:04:20,560
harnesses that are somewhere in here okay uh two of them have three

61
00:04:18,479 --> 00:04:25,360
connectors on them and the last one has four connectors on it it also has the

62
00:04:22,960 --> 00:04:29,080
Corsair Link cable included remember guys unlike the axi series this is 80

63
00:04:27,639 --> 00:04:33,039
plus gold instead of platinum and it doesn't have quite quite the same degree

64
00:04:30,680 --> 00:04:36,560
of integration with corer link but it will allow you to see things like fan

65
00:04:35,120 --> 00:04:40,600
RPM monitoring and power usage monitoring which is kind of nice and

66
00:04:38,280 --> 00:04:45,240
then finally you've got one CPU cable and four PCI Express 6 plus two pin

67
00:04:43,759 --> 00:04:49,240
connectors and you should be able to pretty much fill this baby up with all

68
00:04:47,080 --> 00:04:53,080
that stuff two Molex two floppy connectors if you really still feel the

69
00:04:50,680 --> 00:04:57,720
need for those a quick start guide as well as some included cable ties of

70
00:04:55,000 --> 00:05:02,000
course our case badge and some included screws last thing I wanted to show you

71
00:04:59,919 --> 00:05:08,400
guys is ah yes sample only so this is a sample power supply is the distribution

72
00:05:04,840 --> 00:05:09,960
of the Rails so it's a single 12vt 70.8

73
00:05:08,400 --> 00:05:14,720
amp rail that is capable of providing the entire 850 Watts that this power

74
00:05:12,479 --> 00:05:18,600
supply can supply so that tells us that the 3.3 volt and 5volt rails are

75
00:05:16,840 --> 00:05:23,720
actually derived from the 12volt rail this is an approach that we've been seeing for quite a while here it comes

76
00:05:21,759 --> 00:05:27,919
with a 5-year warranty something I often forget to mention in my unboxings and I

77
00:05:26,360 --> 00:05:33,039
think that pretty much wraps it up thank you for checking out my unboxing and

78
00:05:30,120 --> 00:05:36,759
overview of the RM series power supplies from Corsair these are silence optimized

79
00:05:35,680 --> 00:05:41,560
that's the biggest thing you need to remember don't forget to subscribe to L tchp for more unboxings reviews and

other computer videos like this video if you liked it dislike it if you disliked

81
00:05:43,039 --> 00:05:49,120
it and let me know in the comments do you even care if your power supply is silent I do but that doesn't mean

82
00:05:47,479 --> 00:05:51,280
everyone does so I'd like to hear what you

83
00:05:58,639 --> 00:06:01,919
think oh
