learn more welcome to my unboxing and overview of what might be the most quiet
optimized power supply that we've yet encountered this is the new RM series
from Corsair and it's kind of a replacement for the
txm V2 so that is their TX modular
series so as you might expect it is a modular power supply which means the
cables are not preattached and what you
also might not expect is that it has what Corsair is calling their zero RPM
fan mode so they've brought this down from the ax and axi series to the RM
Series so your fan actually is not even going to spin up at all until you reach
about 40% load so this is your typical power supply fan curve compared to their
zero RPM fan curve now now with all of that said this isn't the first time
we've ever seen this feature in fact it's been around for kind of a while the
power supply in my system doesn't have its fan spin up until it's under a
fairly significant load but it's the first time that we've seen a
manufacturer optimized for silence in a way that goes beyond having the fan not
spin so we've actually got a closed cell foam inside here for packaging and we're
going to go ahead and open this baby up so what Corsair's done is they've
optimized the fan blades on the 135 or
140 mm fan whatever they're calling it they're usually around the same size to
reduce turbulence okay so it's not the first time we've heard a manufacturer
say yes optimized fan design okay uh but
what they've really done is they have hand selected the components inside the
power supply to not only not make noise with the actively moving stuff but to
not make like weird electrical buzzing noises and whining noises which are
often referred to as coil whne even though there's a wide variet of
components inside electronic devices that can cause this kind of noise so
that means and I don't know if you guys have ever seen this before but I certainly have I've seen fanless power
supplies that make annoying noises in fact my power supply which is an XFX
th000 watt Platinum has a ticking noise that is audible even when the Fan's not
spinning at all but I personally appreciate this kind of an optimization
and I'm excited to find out if it actually ends up working so let's take
you guys on a bit of a tour of the product itself they've got a little warning sticker here that says yo the
Fan's not spinning it's okay because
it's designed to do that we've also got a nice open honeycomb mesh at the back
and it otherwise looks pretty much like any other Corsair power supply they've
got a bit of sort of rounded Corner thing going on and those RM logos on the
side are right side up regardless of how you install it in your system on the
front of the power supply or back or whatever you want to call this on this side you find the modular interface so
your 24 pin cable goes here you have five spots for either 4 plus4 pin for
your CPU or 6 plus2 pin for PCI Express so that's four total PCIe and one CPU
connector five peripheral connectors and a Corsair link connector another thing
that's a little bit unique and special about this power supply is the fully
flat modular cables even the 24 pin is
using a flat cable design that is extremely low profile I love this even
going back to Corsair's original HX series power supplies they had the flat
cables on Molex and SATA however this is
the first time I personally seen the flat cable approach taken with 24 pin as
well as with 6 plus2 see nice flat
there's your eight wires and otherwise it's completely flat as well as the four
plus4 pin this makes Cable Management easier even if you don't happen to have
a case that's great for cable management so kudos to Corsair for thinking of that
and implementing it because it's actually not that easy to get factories
to do things like this there's a lot of um there's a lot of ease of assembly
stuff that goes along with color coding things which is why they like to color
code them at the factory and Manufacturing level so there's a little tidbit for you guys in terms of included
connectors we've got two four pin Molex
harnesses each with four connectors on them and then we have three SATA
harnesses that are somewhere in here okay uh two of them have three
connectors on them and the last one has four connectors on it it also has the
Corsair Link cable included remember guys unlike the axi series this is 80
plus gold instead of platinum and it doesn't have quite quite the same degree
of integration with corer link but it will allow you to see things like fan
RPM monitoring and power usage monitoring which is kind of nice and
then finally you've got one CPU cable and four PCI Express 6 plus two pin
connectors and you should be able to pretty much fill this baby up with all
that stuff two Molex two floppy connectors if you really still feel the
need for those a quick start guide as well as some included cable ties of
course our case badge and some included screws last thing I wanted to show you
guys is ah yes sample only so this is a sample power supply is the distribution
of the Rails so it's a single 12vt 70.8
amp rail that is capable of providing the entire 850 Watts that this power
supply can supply so that tells us that the 3.3 volt and 5volt rails are
actually derived from the 12volt rail this is an approach that we've been seeing for quite a while here it comes
with a 5-year warranty something I often forget to mention in my unboxings and I
think that pretty much wraps it up thank you for checking out my unboxing and
overview of the RM series power supplies from Corsair these are silence optimized
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
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
everyone does so I'd like to hear what you
think oh
