00:00:00.240 --> 00:00:08.000
so here it is folks arguably the best

00:00:03.679 --> 00:00:10.160
power supply in the world the ax 1500i

00:00:08.000 --> 00:00:14.799
from Corsair is winning recommendations and editors choice awards all over the

00:00:12.320 --> 00:00:17.720
place including the first ever perfect 10 out of 10 at my favorite power supply

00:00:16.560 --> 00:00:24.160
review site johnnyguru.com and the reason goes far

00:00:20.960 --> 00:00:26.420
beyond its 80 plus titanium efficiency

00:00:24.160 --> 00:00:31.439
rating

00:00:31.439 --> 00:00:38.000
a global leader in tech recruiting is celebrating geek pride by giving away 10

00:00:35.600 --> 00:00:44.559
amazing tech prizes for more info visit the modis facebook page or modis.com

00:00:41.680 --> 00:00:48.559
but what's 80 plus titanium Linus i've never heard of that before let alone

00:00:46.480 --> 00:00:53.440
seen a product with that sticker on the box great question 80 plus certification

00:00:51.680 --> 00:00:57.840
showed up back when very little attention was being paid to the

00:00:55.680 --> 00:01:02.320
relatively low efficiency of power supplies at the time something that

00:00:59.600 --> 00:01:06.960
caused pcs to output more heat and consume more electricity it started out

00:01:04.960 --> 00:01:11.920
as a quick and dirty certification that promised a power supply would be at

00:01:08.960 --> 00:01:17.439
least 80 percent efficient at low medium and full load so 20 50 and 100

00:01:15.200 --> 00:01:23.680
since then even though the atx 2.2 specification only requires efficiency

00:01:20.240 --> 00:01:25.759
in the 65 to 70 range performance power

00:01:23.680 --> 00:01:31.840
supply makers have continued to strive for greater and greater efficiency 80

00:01:29.040 --> 00:01:35.360
plus titanium is currently the highest bar to strive for and requires

00:01:33.520 --> 00:01:41.520
efficiency of 90 92 94 and 90

00:01:38.960 --> 00:01:46.720
at loads of 10 20 50 and 100 respectively aside from the

00:01:44.479 --> 00:01:50.479
debatable importance of titanium versus platinum gold or silver efficiency from

00:01:48.560 --> 00:01:55.280
a power bill savings perspective though one amazing thing about this unit is

00:01:52.880 --> 00:02:01.360
that due to its efficiency it can actually deliver its entire capacity off

00:01:58.880 --> 00:02:05.520
of a normal 15 amp circuit so you don't have to get a fancy high current outlet

00:02:03.360 --> 00:02:09.679
installed in your house just to max out your power supply like what we've seen

00:02:07.360 --> 00:02:13.040
in the past efficiency isn't the only story when it comes to performance

00:02:11.039 --> 00:02:17.520
though some 80 plus power supplies are efficient but suffer from poor voltage

00:02:15.440 --> 00:02:22.560
regulation and excessive ripple which can cause instability and damage or even

00:02:20.560 --> 00:02:26.879
destroy your other components in the long term not an issue here though even

00:02:25.040 --> 00:02:31.680
though low ripple and strong voltage regulation are more difficult to achieve

00:02:29.520 --> 00:02:36.640
with higher capacity power supply units Corsair's use of a state-of-the-art dsp

00:02:33.840 --> 00:02:41.360
allows the ax1500i to dynamically manage its own performance to achieve a no

00:02:38.879 --> 00:02:44.959
compromises experience for its users and you also get to use Corsair link to

00:02:43.040 --> 00:02:48.720
monitor power in power out efficiency although i suppose they just derived

00:02:46.800 --> 00:02:52.319
that from the first two fan speed temperatures and even send yourself

00:02:50.800 --> 00:02:56.400
emails if any of those things go out of whack neither physically the first thing

00:02:54.959 --> 00:03:01.599
i noticed taking the unit out of this box is how large it is at 224

00:02:59.519 --> 00:03:06.480
millimeters long it's the biggest power supply that i've ever used and one of

00:03:03.680 --> 00:03:10.640
the biggest i've ever seen make sure if you're planning to buy one that there's

00:03:08.159 --> 00:03:14.959
room in your case for not only the unit but also the modular cables that need to

00:03:12.959 --> 00:03:19.599
stick out at the end of it the sides are unadorned save for the Corsair ax

00:03:17.440 --> 00:03:22.959
branding and on the top you won't find much of anything other than a simple

00:03:21.040 --> 00:03:26.560
sticker with a breakdown of how much of the unit's total capacity can be

00:03:24.560 --> 00:03:32.319
delivered on each of the main rails as well as the usual safety certifications

00:03:28.879 --> 00:03:34.640
of note here is that the entire 1500

00:03:32.319 --> 00:03:39.519
watt capacity can be delivered on the 12 volt rail set sail for graphics card

00:03:37.360 --> 00:03:43.519
city am i right the fan on the bottom is a custom 140 millimeter unit with a

00:03:41.680 --> 00:03:49.200
fluid dynamic bearing and a blade design that is optimized for maximum airflow at

00:03:46.799 --> 00:03:52.400
low noise levels i mean honestly though i don't know why anyone bothers putting

00:03:50.720 --> 00:03:57.680
this on their fan packaging anymore isn't that about like saying a car is

00:03:54.799 --> 00:04:02.239
optimized for maximum power with great fuel economy i mean who is optimizing

00:03:59.840 --> 00:04:05.680
their fans for minimum airflow at maximum noise levels

00:04:04.000 --> 00:04:09.040
anyway that's not the main selling point of the fan for me anyway i'm more

00:04:07.360 --> 00:04:13.280
interested in the fact that it doesn't even turn on

00:04:10.799 --> 00:04:19.759
until around 30 percent load so your power supply can be kicking out 400 plus

00:04:16.560 --> 00:04:22.079
watts of power and be running completely

00:04:19.759 --> 00:04:27.759
fanlessly silent neat at the back is a honeycomb grille a

00:04:25.280 --> 00:04:32.160
standby switch and that unusual larger c19 power cord socket and then finally

00:04:30.560 --> 00:04:36.800
on the opposite end we've got the modular interface with a whopping 19

00:04:35.199 --> 00:04:41.919
connectors with varying levels of usefulness the normal stuff is here 24

00:04:39.680 --> 00:04:47.440
pin connector six peripheral connectors that can be used to connect a total of

00:04:43.600 --> 00:04:49.600
24 SATA and molex devices with five quad

00:04:47.440 --> 00:04:54.560
data cables and three quad molex cables included in the box we've got two spots

00:04:51.759 --> 00:04:58.320
for eight pin CPU connectors and what wait a minute

00:04:56.639 --> 00:05:03.680
that's ten eight pin sockets that can be used to

00:05:00.560 --> 00:05:06.400
connect up to ten pci express eight pin

00:05:03.680 --> 00:05:11.199
connectors and two eps eight pin connectors at the same time more on that

00:05:08.880 --> 00:05:15.199
in a moment uh wrapping things up back here we've got a self-test button a usb

00:05:13.520 --> 00:05:20.080
port for Corsair link software monitoring and another monitoring port

00:05:18.400 --> 00:05:25.360
all right so back to those PCIe connectors Corsair includes a great

00:05:22.400 --> 00:05:30.240
variety of ribbon style flat black PCIe cables to accommodate almost any kind of

00:05:27.840 --> 00:05:35.840
configuration you've got four standard length single six plus twos two longer

00:05:33.199 --> 00:05:40.080
single six plus twos and then two double six plus twos which are fine for most

00:05:38.240 --> 00:05:45.039
cards that have two connectors to reduce cable clutter so you're just running one

00:05:41.840 --> 00:05:48.160
cable but don't try to use those ones on

00:05:45.039 --> 00:05:49.600
an r9 295 x2 you'll want to run two

00:05:48.160 --> 00:05:55.199
separate cables for that because it consumes so much power now

00:05:52.479 --> 00:05:59.120
i wouldn't have minded Corsair mixing things up a little bit in terms of the

00:05:56.880 --> 00:06:04.800
variety of the other included cables maybe a couple of dual satas or like a

00:06:02.560 --> 00:06:08.639
variation or two with tighter spacing between the connectors or something like

00:06:06.319 --> 00:06:12.240
that but this is a very minor complaint and overall the modular cables included

00:06:10.560 --> 00:06:15.680
give you a lot of flexibility in terms of cable management when building your

00:06:13.759 --> 00:06:20.080
pc no matter what kind of case you're using and they look absolutely fantastic

00:06:18.479 --> 00:06:26.240
with every single one of them not just the pci express ones but even the 24 pin

00:06:22.720 --> 00:06:29.280
being that flat ribbon style with all

00:06:26.240 --> 00:06:30.479
black wires very very nice now

00:06:29.280 --> 00:06:34.800
i'm going to break tradition a little bit here and do the conclusion of this

00:06:32.639 --> 00:06:40.639
video before the actual end so stay tuned to find out why but here it goes

00:06:37.120 --> 00:06:41.840
do you need this power supply no of

00:06:40.639 --> 00:06:46.319
course not whatever it can do there are other less

00:06:44.319 --> 00:06:49.199
expensive ways to do that's it that's all there is to it but

00:06:47.759 --> 00:06:52.479
do you want this power supply

00:06:50.880 --> 00:06:57.600
the fact that you're still watching this video would indicate that perhaps you do

00:06:54.479 --> 00:07:00.080
and not entirely without cause yes there

00:06:57.600 --> 00:07:06.000
are other ways to deliver 1500 watts of power to a pc but they lack the elegance

00:07:03.039 --> 00:07:10.880
sex appeal and sheer technological wow factor of this one so there you have it

00:07:08.800 --> 00:07:14.240
it's the best and it comes with a price tag to match but at least you get a 7

00:07:12.960 --> 00:07:19.440
year warranty this sweet cloth bag and

00:07:17.440 --> 00:07:22.520
a case badge that you can stick to your case with pride because you officially

00:07:21.520 --> 00:07:26.880
have a 224 millimeter epeen

00:07:27.039 --> 00:07:31.680
you can't even see what i'm doing but i think you guys know what it is but of

00:07:30.160 --> 00:07:35.199
course you didn't come to Linus tech tips to hear about my decades of

00:07:33.280 --> 00:07:39.360
experience as an electrical engineer and see a detailed teardown of the power

00:07:37.280 --> 00:07:44.720
supply nope we're going to be doing a packaging test as a follow-up to my ever

00:07:41.840 --> 00:07:48.160
popular test on the ax 1200i where i threw it out of a moving vehicle but

00:07:46.160 --> 00:07:53.280
this time we're upping the ante this is the aptly named 400 yard water balloon

00:07:51.039 --> 00:07:58.000
launcher from bam launcher picked this up on amazon and uh

00:07:56.319 --> 00:08:01.840
we are going to be flinging a power supply with it so i've got my lovely

00:07:59.680 --> 00:08:05.919
assistants luke and nick the power supply is in here we are going to show

00:08:04.400 --> 00:08:10.560
you the power supply when we're done with this but uh the point of this

00:08:08.080 --> 00:08:14.400
exercise is uh let's just we haven't tried this before

00:08:12.479 --> 00:08:19.039
so you'll have to just bear with us we're on the roof here

00:08:15.840 --> 00:08:19.039
are you guys good yeah

00:08:19.840 --> 00:08:22.960
oh that's unfortunate

00:08:25.360 --> 00:08:32.800
so it's not really designed for power supplies and more for water balloons but

00:08:30.960 --> 00:08:37.839
i think still think it performed admirably

00:08:34.800 --> 00:08:40.719
given the circumstances

00:08:37.839 --> 00:08:45.839
you can see that the uh folded over marketing flap didn't actually fare that

00:08:43.519 --> 00:08:50.480
well in the in the fall and the oh wow yeah the outer carton in

00:08:48.480 --> 00:08:55.279
general is just kind of coming apart here in fact the inner carton

00:08:53.600 --> 00:08:58.240
is having a little bit of trouble here as well but

00:08:56.640 --> 00:09:01.200
let's go ahead and so the point of this is

00:09:00.000 --> 00:09:05.120
you know what you're going to spend a bunch of money on a super you know

00:09:03.440 --> 00:09:10.080
high-end power supply you want to make sure that when it arrives you're actually going to be powering up your

00:09:08.080 --> 00:09:13.839
rig with it as opposed to dealing with shipping damage rma so

00:09:12.320 --> 00:09:18.959
you can see here the cables themselves

00:09:16.240 --> 00:09:18.959
immaculate

00:09:19.279 --> 00:09:25.120
the power supply in it's okay my cat chewed on it but other than

00:09:24.320 --> 00:09:31.760
that pristine soft foam

00:09:28.560 --> 00:09:33.519
totally not damaged capable of handling

00:09:31.760 --> 00:09:37.640
multiple falls and the power supply itself

00:09:39.360 --> 00:09:45.440
once again Corsair's packaging exceeds

00:09:42.959 --> 00:09:48.560
no loose parts my expectations in fact a lot of the internals of this power

00:09:46.640 --> 00:09:52.480
supply if you even check out in there are actually like glued in or siliconed

00:09:50.880 --> 00:09:56.320
in so i was i was pretty confident it was gonna survive but of course

00:09:54.320 --> 00:09:59.680
falling from this kind of a height or wherever it fell from eyes there's no

00:09:58.480 --> 00:10:06.560
guarantees all right guys so if you enjoyed that kind of goofing around then i've got

00:10:03.279 --> 00:10:09.360
