1
00:00:07,040 --> 00:00:16,960
today we will be doing an upside down unboxing of the fsp AUM series gold 400

2
00:00:13,360 --> 00:00:19,640
power supply so personally I'm a big fan

3
00:00:16,960 --> 00:00:24,279
of Highly efficient reasonable wattage power supplies and the reason for that

4
00:00:21,720 --> 00:00:29,359
is actually outlined in a recent edition of NC Tech tips that I did and uh you

5
00:00:27,920 --> 00:00:34,520
you should check that out it's called power supply y power consumption system

6
00:00:32,079 --> 00:00:39,480
power consumption or something like that and um what we basically do is we take a

7
00:00:37,440 --> 00:00:42,719
system we upgrade it from a very very basic configuration all the way through

8
00:00:41,200 --> 00:00:47,360
all the steps up to a very high-end machine and then we discover as we go

9
00:00:45,039 --> 00:00:51,879
along how much power it consumes so what we found out was we plugged in a 1200

10
00:00:49,559 --> 00:00:55,879
watt 80 plus gold power supply and power consumption sucked the efficiency was no

11
00:00:54,199 --> 00:01:01,000
good because we were consuming so little power from it whereas if we'd taken a

12
00:00:57,879 --> 00:01:02,960
400 watt 80 plus gold power supply we

13
00:01:01,000 --> 00:01:07,680
would have actually consumed less power as a whole so it's got kind of a neat

14
00:01:05,119 --> 00:01:11,080
finish on it it's got a 5-year warranty it's recommended for gaming and

15
00:01:09,400 --> 00:01:14,920
workstation remember you can power a decent gaming machine off a 400 wat

16
00:01:12,920 --> 00:01:20,280
power supply here's the overall specs which we'll see as we open up the unit

17
00:01:16,880 --> 00:01:22,920
itself fsp Maya IC multiple intelligence

18
00:01:20,280 --> 00:01:26,640
ability chipset okay uh what else have we got here constant holdup control

19
00:01:25,040 --> 00:01:31,400
performs continuous adjustments according to the output load in order to

20
00:01:29,560 --> 00:01:34,920
achieve the best possible efficiency so this is all about efficiency as I

21
00:01:32,799 --> 00:01:40,360
mentioned before it is 80 plus gold let's just go ahead and start opening up

22
00:01:38,560 --> 00:01:45,640
the unit itself so the first thing we find inside is a quick start guide which

23
00:01:42,600 --> 00:01:48,840
pretty much tells you not a whole

24
00:01:45,640 --> 00:01:50,119
lot English is the fourth language in

25
00:01:48,840 --> 00:01:54,920
here if I can even find it shows you the connectors and whatnot we've also got

26
00:01:52,680 --> 00:02:04,200
four black thumb screws nice little touch an FSB case badge as well as uh

27
00:01:59,159 --> 00:02:07,280
three velcro cable ties power cable is

28
00:02:04,200 --> 00:02:09,239
included and then the power supply

29
00:02:07,280 --> 00:02:14,720
itself uh wrapped in my favorite kind of foam so the Clos cell foam that is

30
00:02:11,640 --> 00:02:17,040
really very very durable and you can see

31
00:02:14,720 --> 00:02:20,239
right here this is a 400 W power supply so it doesn't have a whole lot of cables

32
00:02:18,560 --> 00:02:26,720
attached but let's look at the unit itself first so it's got a goldish

33
00:02:24,239 --> 00:02:30,040
blackish darkish this is a really neat powder coat finish this is actually very

34
00:02:28,280 --> 00:02:34,800
similar to the finish that I have on my tj07 case my personal case I had it done

35
00:02:33,000 --> 00:02:39,720
by Mountain mods it's they call it black wrinkle it's very durable completely

36
00:02:37,400 --> 00:02:43,720
fingerprint proof almost scratch proof and looks outstanding it's like a matte

37
00:02:42,280 --> 00:02:47,280
black but it has a little bit of shine to it almost like it has brush Strokes

38
00:02:45,400 --> 00:02:51,680
in it like it was painted piece of plastic in there we've got a 120 mm

39
00:02:49,680 --> 00:02:55,280
cooling fan covered by a grill it's covered by a little piece of plastic

40
00:02:53,480 --> 00:03:00,360
here that'll protect that go ahead and remove that there you go now you can see the full shininess at the back we have

41
00:02:58,599 --> 00:03:03,840
kind of an arrow design to The Back Grill that looks like it should provide

42
00:03:02,040 --> 00:03:09,440
pretty unrestricted air flow through the back of the power supply uh Power input

43
00:03:07,040 --> 00:03:13,319
power switch on both sides of the unit we

44
00:03:10,239 --> 00:03:16,319
find oh hold on what's that oh that

45
00:03:13,319 --> 00:03:18,640
comes off okay we find fsp branding as

46
00:03:16,319 --> 00:03:22,560
well as that nice uh black wrinkle finish on the top we find the overall

47
00:03:20,959 --> 00:03:27,159
specs of the unit so let's have a look here you can see it does have dual 12vt

48
00:03:24,879 --> 00:03:32,560
rails that are together capable of providing up to 384 watts of power so

49
00:03:29,959 --> 00:03:36,959
that is almost the full 400 wat capacity of this power

50
00:03:34,439 --> 00:03:39,840
supply and then we move around to the other side of the unit where we find

51
00:03:38,239 --> 00:03:45,120
more fsp branding you can see what they've done is if your Windows on the

52
00:03:42,439 --> 00:03:48,760
normal side of your case no matter oh no okay it will be upside down if you go

53
00:03:46,560 --> 00:03:51,959
this way so the fsp will be right side up if you install it this way around

54
00:03:50,840 --> 00:03:57,760
we've got a few more of those ventilation arrows here on the front of the unit and now let's have a look at

55
00:03:55,599 --> 00:04:04,519
the sleeving as well as the cables that come preattached to the r from 400 wat

56
00:04:02,079 --> 00:04:09,319
so here we are we have our 20 plus 4 pin power connector you can see that uses a

57
00:04:07,000 --> 00:04:13,360
a pretty decent quality sleeving on it so you can't really see the color of the

58
00:04:10,760 --> 00:04:18,759
wires too much through that okay next we have our 4 plus 4 pin EPS power

59
00:04:16,680 --> 00:04:21,160
connector so this is quite a long cable which is good because if you have a

60
00:04:19,880 --> 00:04:27,600
bottom mounted power supply you're going to want to be able to reach the top left corner of the motherboard where that's

61
00:04:23,960 --> 00:04:30,160
usually situated here we have a 6 plus2

62
00:04:27,600 --> 00:04:34,840
so 8 Pin PCIe power adapter I would have liked to see an additional one of these

63
00:04:31,960 --> 00:04:38,160
but you can always use adapters so we do have three Molex connectors and one

64
00:04:36,639 --> 00:04:42,680
floppy connector so you could use a couple of those to get another PCIe 6

65
00:04:40,600 --> 00:04:46,280
pin out of it remember this will power a decent machine right guys so even with

66
00:04:44,440 --> 00:04:51,919
like a GTX 560 you'll have no problem using a 400 wat power supply and then

67
00:04:48,520 --> 00:04:53,400
finally four SATA power connectors so

68
00:04:51,919 --> 00:04:57,880
all of those are sleeved and then terminated individually so it looks

69
00:04:55,520 --> 00:05:01,240
quite nice so let's just see if there's anything else we missed here before we

70
00:04:59,199 --> 00:05:05,800
wrap it Up acoustic noise they're claiming it's whoops they're claiming

71
00:05:03,120 --> 00:05:09,479
it's quite quiet even up to 100% load most power supplies you see on their

72
00:05:07,520 --> 00:05:14,160
noise charts they usually kind of ramp up like this near 100% load this one

73
00:05:11,520 --> 00:05:20,680
does not and in terms of efficiency because it is 80 plus gold it is peaking

74
00:05:16,919 --> 00:05:22,880
up at around 90% efficiency so thank you

75
00:05:20,680 --> 00:05:27,039
