so here it is folks arguably the best
power supply in the world the ax 1500i
from Corsair is winning recommendations and editors choice awards all over the
place including the first ever perfect 10 out of 10 at my favorite power supply
review site johnnyguru.com and the reason goes far
beyond its 80 plus titanium efficiency

but what's 80 plus titanium Linus i've never heard of that before let alone
seen a product with that sticker on the box great question 80 plus certification
showed up back when very little attention was being paid to the
relatively low efficiency of power supplies at the time something that
caused pcs to output more heat and consume more electricity it started out
as a quick and dirty certification that promised a power supply would be at
least 80 percent efficient at low medium and full load so 20 50 and 100
since then even though the atx 2.2 specification only requires efficiency
in the 65 to 70 range performance power
supply makers have continued to strive for greater and greater efficiency 80
plus titanium is currently the highest bar to strive for and requires
efficiency of 90 92 94 and 90
at loads of 10 20 50 and 100 respectively aside from the
debatable importance of titanium versus platinum gold or silver efficiency from
a power bill savings perspective though one amazing thing about this unit is
that due to its efficiency it can actually deliver its entire capacity off
of a normal 15 amp circuit so you don't have to get a fancy high current outlet
installed in your house just to max out your power supply like what we've seen
in the past efficiency isn't the only story when it comes to performance
though some 80 plus power supplies are efficient but suffer from poor voltage
regulation and excessive ripple which can cause instability and damage or even
destroy your other components in the long term not an issue here though even
though low ripple and strong voltage regulation are more difficult to achieve
with higher capacity power supply units Corsair's use of a state-of-the-art dsp
allows the ax1500i to dynamically manage its own performance to achieve a no
compromises experience for its users and you also get to use Corsair link to
monitor power in power out efficiency although i suppose they just derived
that from the first two fan speed temperatures and even send yourself
emails if any of those things go out of whack neither physically the first thing
i noticed taking the unit out of this box is how large it is at 224
millimeters long it's the biggest power supply that i've ever used and one of
the biggest i've ever seen make sure if you're planning to buy one that there's
room in your case for not only the unit but also the modular cables that need to
stick out at the end of it the sides are unadorned save for the Corsair ax
branding and on the top you won't find much of anything other than a simple
sticker with a breakdown of how much of the unit's total capacity can be
delivered on each of the main rails as well as the usual safety certifications
of note here is that the entire 1500
watt capacity can be delivered on the 12 volt rail set sail for graphics card
city am i right the fan on the bottom is a custom 140 millimeter unit with a
fluid dynamic bearing and a blade design that is optimized for maximum airflow at
low noise levels i mean honestly though i don't know why anyone bothers putting
this on their fan packaging anymore isn't that about like saying a car is
optimized for maximum power with great fuel economy i mean who is optimizing
their fans for minimum airflow at maximum noise levels
anyway that's not the main selling point of the fan for me anyway i'm more
interested in the fact that it doesn't even turn on
until around 30 percent load so your power supply can be kicking out 400 plus
watts of power and be running completely
fanlessly silent neat at the back is a honeycomb grille a
standby switch and that unusual larger c19 power cord socket and then finally
on the opposite end we've got the modular interface with a whopping 19
connectors with varying levels of usefulness the normal stuff is here 24
pin connector six peripheral connectors that can be used to connect a total of
24 SATA and molex devices with five quad
data cables and three quad molex cables included in the box we've got two spots
for eight pin CPU connectors and what wait a minute
that's ten eight pin sockets that can be used to
connect up to ten pci express eight pin
connectors and two eps eight pin connectors at the same time more on that
in a moment uh wrapping things up back here we've got a self-test button a usb
port for Corsair link software monitoring and another monitoring port
all right so back to those PCIe connectors Corsair includes a great
variety of ribbon style flat black PCIe cables to accommodate almost any kind of
configuration you've got four standard length single six plus twos two longer
single six plus twos and then two double six plus twos which are fine for most
cards that have two connectors to reduce cable clutter so you're just running one
cable but don't try to use those ones on
an r9 295 x2 you'll want to run two
separate cables for that because it consumes so much power now
i wouldn't have minded Corsair mixing things up a little bit in terms of the
variety of the other included cables maybe a couple of dual satas or like a
variation or two with tighter spacing between the connectors or something like
that but this is a very minor complaint and overall the modular cables included
give you a lot of flexibility in terms of cable management when building your
pc no matter what kind of case you're using and they look absolutely fantastic
with every single one of them not just the pci express ones but even the 24 pin
being that flat ribbon style with all
black wires very very nice now
i'm going to break tradition a little bit here and do the conclusion of this
video before the actual end so stay tuned to find out why but here it goes
do you need this power supply no of
course not whatever it can do there are other less
expensive ways to do that's it that's all there is to it but
do you want this power supply
the fact that you're still watching this video would indicate that perhaps you do
and not entirely without cause yes there
are other ways to deliver 1500 watts of power to a pc but they lack the elegance
sex appeal and sheer technological wow factor of this one so there you have it
it's the best and it comes with a price tag to match but at least you get a 7
year warranty this sweet cloth bag and
a case badge that you can stick to your case with pride because you officially
have a 224 millimeter epeen
you can't even see what i'm doing but i think you guys know what it is but of
course you didn't come to Linus tech tips to hear about my decades of
experience as an electrical engineer and see a detailed teardown of the power
supply nope we're going to be doing a packaging test as a follow-up to my ever
popular test on the ax 1200i where i threw it out of a moving vehicle but
this time we're upping the ante this is the aptly named 400 yard water balloon
launcher from bam launcher picked this up on amazon and uh
we are going to be flinging a power supply with it so i've got my lovely
assistants luke and nick the power supply is in here we are going to show
you the power supply when we're done with this but uh the point of this
exercise is uh let's just we haven't tried this before
so you'll have to just bear with us we're on the roof here
are you guys good yeah
oh that's unfortunate
so it's not really designed for power supplies and more for water balloons but
i think still think it performed admirably
given the circumstances
you can see that the uh folded over marketing flap didn't actually fare that
well in the in the fall and the oh wow yeah the outer carton in
general is just kind of coming apart here in fact the inner carton
is having a little bit of trouble here as well but
let's go ahead and so the point of this is
you know what you're going to spend a bunch of money on a super you know
high-end power supply you want to make sure that when it arrives you're actually going to be powering up your
rig with it as opposed to dealing with shipping damage rma so
you can see here the cables themselves
immaculate
the power supply in it's okay my cat chewed on it but other than
that pristine soft foam
totally not damaged capable of handling
multiple falls and the power supply itself
once again Corsair's packaging exceeds
no loose parts my expectations in fact a lot of the internals of this power
supply if you even check out in there are actually like glued in or siliconed
in so i was i was pretty confident it was gonna survive but of course
falling from this kind of a height or wherever it fell from eyes there's no
guarantees all right guys so if you enjoyed that kind of goofing around then i've got
great news we have officially named our

there our first video firing actual
water balloons with our launcher will be coming soon and we've got lots of great
stuff lined up including an automatic gumball machine some sweet rubber band

so be excited for that or or don't
but if you're not excited for it then probably don't subscribe or maybe
subscribe anyway and then give us a chance to win you over and if you don't
