previously on dawid does tech stuff: it's not firing up with the 1070 in it either
oh no i killed it it's the 3080ti was too much for it and the power supply just committed hara
caring which brings me to today's video where i got my hands on a beefier power supply for the
msi system all the way from japan so that i can do everything in my power to get that 3080ti to
run terribly in this msi system even if it costs me my fingers ah but before that it's time for a
word from today's video sponsor today's video is sponsored by be quiet and their pure loop aios
now it goes without saying that the pure loop aios are easy to mount come in a variety of sizes and
with its unique pump design is surprisingly quiet for an aio but what i like most about these aios
is their minimalist aesthetic i think they look real sexy with that brushed metal faceplate and
that diffused white led and considering that you don't have to pay ridiculous rgb tax on these
they are surprisingly affordable and they have a fill port on an aio which i think is really cool
so if you like the look of these check out the pure loop aios using the link in my
description below and thank you again be quiet for sponsoring today's video
now a lot of you are probably thinking darvit that is just a 600 watt power supply which
really is not a great pairing for an rtx 380 ti but the main reason i got it is because i really
like triggering garys so for the type of person that gets offended by this power supply choice
look at it look at it no actually the real reason is this was just the best option i could get
fsp does make an 850 watt flex power supply but it's got the same problem that i think is going to
be the issue for the silverstone power supply that we'll discuss in a little bit and it's longer than
the power supply that came in the msi system and i didn't want to risk it not fitting in the case now
another interesting thing about this silverstone power supply is that it's got a cybernetics
platinum rating which may just sound like a kirkland brand 80 plus rating but cybernetics
actually has a more comprehensive test suite that the power supply needs to pass in order to get the
rating so i actually think this is better than 80 plus okay so let's have a closer look at the
power supply we're going to use to torture an rtx 3080 ti with wow that is not super well packaged
now it comes with quite a standard japanese power cord here with the little extraneous ground cable
pull that off and oh it's so cute and little now on the back we have a worryingly small fan
i think this is gonna just be inappropriately noisy but we'll see how that goes
and then uh we've got a non-modular power supply now the msi system does actually have
some proprietary connectors on the motherboard for power but i did get an adapter off of amazon so we
should still be able to use this power supply now this power supply does have a 50 amp 12 volt rail
on it which i'm hoping will be able to handle a bottlenecked 3080ti uh but we'll see how it
goes you know we'll see what happens all i hope is that it doesn't explode under any form of load
so that we can like underclock and underpower the gpu that it in a way that it does work but now
that we've had a very brief look at this little power supply let's drop it into the msi system
and just hope that when the previous power supply died it didn't just take the whole system with it
now if you have a closer look at this motherboard you can see that it looks like it's just a
slightly extended standard itx motherboard which means that if the previous power
supply did kill this motherboard we may be able to just replace it like if you drop
an itx motherboard over it you can see the the screw holes do actually line up for it
oh yeah don't you just love a nice proprietary connector
now you can see here that the silverstone power supply board is actually smaller
than the one that's in here hopefully i can get it mounted decently do this
okay well that's not ideal now after evaluating various options i think the ghettoist solution
is going to be the best i'm just going to kind of leave it resting like this because with the
pc the right way up it's just going to be wedged down by that plate which there's very little
clearance so it is actually going to kind of hold it in place yeah why not let's let's sort the
cables out and then see if the system runs which went well oh it's such a small hole please ah
come on oh that's just one ah
now considering that we have the predictably inconvenient proprietary motherboard power
we're gonna need this adapter which is a 24 pin to 10 pin cable in order to get that uh
that silverstone power supply to work in here okay well that all looks fine to me
so let's close it up and find out if that power supply took its family with it on its way out
i think it killed the whole system on its way out ah well that's a shame i'm i'm pretty sure
the actual core system in here has died the next step is to replace it with a newer itx motherboard
now i think if we can remove this hard drive cage it'll make it a whole lot easier to get
that motherboard out now i do think that it is removable because i've already undone a
couple of screws holding it in place but it's not coming undone yet uh so maybe
there are a couple of more screws under here that we need to get out wait so under this top panel
which i didn't even realize was removable there's a hidden hot-swappable ssd caddy
who designed this case why did they hide two hot-swappable hard drive caddies
under the dvd drive that's hidden under the top panel
this is such a ridiculous pc holy crap because of all of this proprietaryness this is definitely
not going to be a clean transplant but you know you never know until you try
okay so after about two years of struggling here is the slightly deformed itx motherboard you can
have a closer look at all of the proprietary connectors we've got the 10 pin over here
we've got some proprietary fan connectors over here at least all of the sata was standard but
here we've got a bunch of like front panel connectors and stuff now i quickly want to
test this motherboard outside of the case with a known working power supply just to make sure that
it did actually suffer death by 3080ti because i don't see any obvious signs of motherboard failure
like scorch marks around the power delivery or anything like that a few moments later no it did
that's actually not the driest looking thermal base okay well there's a big problem uh
msi you just yeah couldn't have made this harder could you because of the fact that
the cpu socket is oriented differently on this motherboard and you can see
that it's actually further away from the rear i o because of those factors it means that this cooler
it can't fit on that because even if you have less obstruction over here and you can actually
get the cooler to mount it actually overhangs the back of the motherboard so it's not gonna work
so long story short our options are getting more limited here and i think our best bet is probably
going to be to use a motherboard with just like a standard cooler on it something like this
stock amd cooler which actually is lower profile than this coolers high point the problem is that
this cooler is just going to be asphyxiated by the back of the gpu so the temperatures are
going to be horrendous in here but i i don't know what other options i have at this point
would you look at that at least the screw holes line up so the pcie bracket actually
plugged in which is good uh although we do not have a whole lot of clearance as you can see
my finger can barely fit between the bracket and the top of the fan and not
only that but the rtx 3080ti founders edition card has a rear blowing fan
which is very possibly just gonna be dumping a bunch of heat into the cpu cooler so hopefully
we don't cause some silicone fusion today but let's reassemble the system and see how that goes
okay now this is some real satan level design decision making here because
they take a standard connector right this connector is what a front panel connector
looks like in a case like an nzxt one uh so you think like oh that may actually fit
but what they've done is they've just shrunken it ever so slightly down from standard so that
it looks like a standard connector but it doesn't actually fit on anything useful now
the reason that this whole power button fiasco is so irritating is that once we have a graphics
card in here we're not just gonna be able to screwdriver savage power on the system because
there's a graphics card in the way now what i've done in order to get around msi's evil ways
is i just stole the power button from a different case so that i can position this somewhere more
easily accessible inside this pre-built case i don't know i feel like that isn't looking
too bad so yeah let's just drop the graphics card back in here and then test it i guess
hey would you look at that the cpu cooler actually has a bit of room to breathe that's enough right
nice that sounds good you can see things are spinning in there yay success
oh it shot down again well the battlefield 5 menus are clearly just way too much for
these flex power supplies but considering that we've got some some motherboard rgb
still going i think that the power supply didn't die this time so that's a good start
okay nice there we go it's not dead this time which is a genuine improvement over
the previous configuration so now now we can start playing around with the power limits on that gpu
and then maybe we can get it to a point where it can run battlefield
5's menus which really would be the dream that power supply is really annoyingly loud so all
i'm going to do here is take the power limit slider and just kind of just do that with it
i mean i could if i wasn't a complete savage under vault of the gpu uh but let's see if this works
and then we'll we'll take it from there so as you can see it is drawing a whole lot less power
oh come on it's crashed again what the hell okay well let's just do that okay there we go
it's drawing 110 watts now like it the power supply has to be able to handle this right
okay well at 110 watts the system's not crashed yet so that's good that's a step in the right
direction our rtx 3080 ti is drawing just 110 ish watts and we're getting 210 megahertz of core
frequency going uh but we're we're still getting about 60 frames per second in battlefield 5 which
interestingly enough battlefield 5 is actually performing worse now than it did with the 1070
but that's not the point of this video we've got we've got a bigger graphics card name number in
the system that's the only thing we care about and um the system's actually running so i think
what i'm going to do now is slowly pull up that slider in msi afterburner until the pc crashes
oh that's made a considerable performance difference and it's not increased our power draw
that much so that's interesting going from 110 ish to 140ish has given us more than double the fps
okay so the power draw to performance metric of the rtx 3080 ti is definitely not a linear graph
and i think now it's actually running better than it did on the 1070 if i'm not mistaken
okay so that's made quite a big difference to our power draw figure but our frame rates it's
a little bit better it's not much better though now clearly the reason we're not
getting more performance is because that 5300 g is a bottleneck here i'm not quite sure why
it's drawing so little power in this situation but either way let's replace the cpu in there
and see if we can get more performance out of the system holy that is glued on there oh whoa
oh there we go wow that thermal paste is dry as hell that is definitely one of the reasons
the temperatures were struggling even with a low power draw that all makes sense now
now even with that new cpu in there and just a 58 power draw limit on the rtx 3080 ti
we've had to bump up the resolution from 1080p to 4k just so that we don't run into a cpu bottleneck
but now that we are at 4k ultra settings uh we're still getting about 110 frames per second and it's
it's running well everything seems to be okay so let's let's bump up the power draw a little
bit and see how it goes oh yeah we're actually already getting to a point again at 4k where the
3600 is a bottleneck so that's wow that is crazy the the 3080ti even when heavily kneecapped is
still a complete monster where the power supply is gonna tap out so let's see when we hit that
oof that that cpu is not having a good time anymore
there's someone with me oh there we go 75 is just too much for it at this point so at the end of the
day i think the reason why flex power supplies crumble neath the mighty tread of an rtx 3080 ti
is because the ones that i've found only have a single pcie power cable
that splits off to dual eight pins making it easy for the graphics card to overdraw the
cable and lead to power supply death which brings me to the end of the video bye you
