every one today we're taking apart two EVGA GTX 1650s both of which have power connectors this first card is the one we reviewed so we're gonna take this one apart it's a dual fan cooler EVGA has done some new things to bring cost down both for them and then obviously for the consumer as well so this is one of the cheaper dual fan cards EVGA is made in a while and we're gonna see why that is what what did they do to get it cheaper and did EVGA sacrifice anything in the process of so doing so we're gonna take this one apart and we just got this one in today as well which is a single fan card that's pretty fat it's too it's it's like three slots for 1650 so that's what we're gonna look at today and hopefully we can learn something despite a lot of people not really particularly caring about the six pin power connector 1650s but we'll look at it anyway before that this video is brought to you by deep pools captain 240 pro closed-loop liquid cooler the new captain 240 pro comes with the RGB illuminated fans and a pump easily synchronized to each other for color matching in your system the captain 240 pro radiator also uses a unique elastic pressure relief bladder in the water tank as a leak prevention mechanism it expands and contracts based upon liquid temperature to counteract a IO leak concerns the cooler is available now and you can learn more at the link in the description below this is the EVGA 1650s c ultra it's a 90 watt card as opposed to 75 watts and will just you get me a bigger one alright so we're just gonna take this apart this will be fast probably this one is the one we reviewed and it did well like as far as as as well as a 1650 can do the appeal of these cards is generally used without a power connector but this one does have one at overclock it's pretty darn well we hit twenty one hundred megahertz sort of and then 2115 very briefly about how that 20 85 which is a good place to be and it's only four screws holding down the cooler itself evj does put a sticker covering one of the screws but it is not a warranty void if removed sticker it's actually just a tamper sticker so they can tell if you've if they need to replace the paste or something when they are ma it there we go so very easy to open up and a couple of things this card that we have is a PBT model so this is like a test production run before mass production for consumers so it doesn't go through some of the processes that a card you would buy would go through like some of the automatic optical inspection or Aoi machines that we've shown in the past would catch this issue for example so there's a quality control issue that should not make it to production or mass production because it would be seen by either a person assembling it or by the machine but these are more or less hand built for getting them to the press as quickly as possible because Nvidia didn't give anyone enough time for this product launch so anyway yeah part of the inductor like cover is missing but that doesn't affect performance or anything that's basically irrelevant and then this is an example of what it should look like where it's got the full cap but that cap doesn't do anything functional that's affecting performance here it just covers the inductor coil so the rest of this card pretty simple fan goes in there you got a big blank area of PCB but need something they had to put something there anyway especially for the fan coverage the heatsink was gonna be that size EVGA has done some down cost in unique ways we'll show you one of those so here is an example of creative def costing this is an EVGA 1070 you'll notice that the PCIe slot is fully populated with pins whereas both of these cards the 1650s are missing pins and that brings cost down a bit this pins aren't all that useful with something that's got the bandwidth of a 1650 are you not high so that's one way of down costing but otherwise it's it's really so it's for one gigabyte memory modules these are micron memory modules and the GPU itself we might as well look at so everyone knows what that looks like all right good enough there's a GPU so that is a Tu Tu 117 - 300 - a 1 that last a one signifies that its production run product GPU from Nvidia and our belief is that this is not a full fully enabled t1 17 so there might be a 1650 ti if they wanted to do one in the future really depends on if there's anybody it feels pressure or a reason to but that's the GPU it's very small we can measure the die size in a second and if you want one of these mod maps that I'm working on these are our mod Maps we design these so this one's a GPU teardown mat it's got things like capacitor labels on the GPU under here so you can see we've labeled the the inductors the MOSFETs capacitor is all that kind of thing I say you can learn as you go when you do this assembly projects also protects the service you're working on and it's got anti-static grounding that goes actually to ground unlike some of the products out there then we have the grid for GPU screw placement so let's let's measure the GPU that's on stored out gamers nexus net if you want to pick up the medium sized little e back in stock in the next few days and shipping immediately you can back order now it'll ship out or the large size is restocking as well which is the one under the one I'm working on roughly fourteen and a half millimeters wide roughly fourteen and a half millimeters tall so the VRMs over here we have three inductors got the power stages next to it another inductor over here ignoring the damaged one and on the shunt resistor side we so we've got one chunk resistor right here and one down here this one will run to the 12 volt line and the PCIe slot and the shunt resistor will probably run to this PCIe connector so if for some reason you wanted to short these which would raise your power limit then you could short this one if you really want to do it seems a bit odd but that'd be what you do and if you want to validate this you just get a multimeter you check the shunt leg versus the 12 volt line and that would tell you which one goes to which power connector and then we do on these mats if you need it have a GPU power pin out actually talk about medium matte as well but there's a six pin and an eight pin PCIe power right there so you'd match it to the 12 volt which is that yellow block and that would tell you the correct chunk resistor so for the back of the card there's almost certainly not anything there but we'll just take the back plate off anyway give a J didn't put a metal backplate on this one it's $20 more than MSRP so that's part of that cost and I will note that originally when we took this apart these three of these screws were loose which wasn't really that exciting to discover but like before I got them they release but it's pre-production it's not mass production so we'll give EVGA the benefit of the doubt that that was just because it didn't go through the same quality control steps as usual so you should be good on the consumer side in theory while we're on that topic too this was taken apart after the review was completed all the tests were done and all the numbers were published so so this is we don't disassemble before testing so the back of this is basically blank there's really nothing going on here in fact the GP is pretty obvious but this card is very straightforward so we can move on from the PCB and look instead at the cooler so what's happening here well this is a cheaper one as I said it's down costed in a few ways instead of having a typical aluminum fin stack EVGA has a black out matte color still aluminum sort of fin stack fins are very a few and far between but they're good enough but actually this card cool is pretty damn well so when we overclocked it it was still in the sixty is the part power target seems to be about sixty degrees Celsius so the fans just spin up to meet that target but the point here is that it's able to do that with less cooling solution because that GPUs not really doing more than 90 watts for the most part on this card so you can go six percent above that but 90 watts about the limit which doesn't really take a whole lot of cooling power there's a single heat pipe this is an eight millimeter heat pipe you can see that it's a fat cylindrical pipe which is more effective than the flat ones but flat ones are often used for GPUs for surface area or just fitment reasons to make sure it fits in the smaller spot but this one is is only squared in some areas so it's not a not a flat pipe like you would see on some of the other cards eight millimeters for that that goes straight across the middle of the GPU so you get some contact there that's your evaporator and then the liquid will the water pure water will evaporate go up the pipe condense come back down capillary action all that stuff we've described before and then the cold blade itself is an aluminum cold plate the copper pipe is soldered to it and there's a bit of like small kind of imperfection right here all the way down it's covered with their own paste in that area right now but that is probably a PBT defect as well but either way it cooled fine for the GPO the memory is a little bit more concerned but not that much because this card's still low end and there's a lot of airflow above it even though most of it can't get through the card except right there but the memory will be a for-sure a bit hotter than we typically like to see and that's because there's no direct contact between the memory and the cold plate but that does also mean that the cold plate can cool and dissipate more of the heat from the GPU itself so as long as the memories within spec then it's fine it's it's not running as hot as the GPU is so these don't sink directly to the cold plate is actually we would like to see some better contact to these for sure but it's a low-end card and you make cut corners somewhere and that corner is not particularly important with the model like this so let's look at the next one this is the next one this is the XC don't think it's called ultra much sure anymore keep it yeah it does a lot of different things their names it's an XC so this card is a three slot design or basically maybe 2.8 I think it's no it's three they just committed to it this time so this is actually three slots that's good to see him three slot design single fan it's larger heatsink will allow it to obviously pull some more of the heat away without needing quite as much active cooling power so it can keep the fan off for a little bit longer this is the tamper seal but it's not a warranty void sticker that's something we've confirmed a lot it's already loose so only four screws to get these off which means there's no base plate once again okay there's a little closed on the throne paste at the edges but so anything of note is this the same PCB yep Oh actually there's a great comparison we're talking about that damaged in dr earlier if you didn't believe me there's your evidence but again this is just this card at the top is a mass production model that's what you would buy there's a pre-production model so hopefully that's the only difference there but either way same PCB same vrm layout same component placement the difference is the cooler primarily and let's just clean off the GPU to see if there's anything interesting to reveal but I don't think there will be so still tu 117 300 a1 nothing new there it's still made in Taiwan yes sir they both in Taiwan they're both made in Taiwan so that's gonna be TSMC and then this one has four micron modules as well so it's all the same no back plate for this model and then the cooler is very fat so there's the aluminum heatsink versus the two slot card with two fans this one does not have the heat pipe in it and still doesn't contact the memory but it does have a bigger aluminum fin stack it's just that these I mean this is typically this is what you see on these lower end cards where instead of like a proper aluminum heatsink like maybe this one would have for example right there where the fins are either this way or that way instead of a proper big aluminum heatsink like that with heat pipes inside of it you know with just the aluminum heatsink with no heat pipes in it and they just do black out so it looks a bit better but that's the design on that one one fan the assembly is pretty straightforward if you wanted to disassemble it to replace the fan you would pull these screws out actually I don't think you even need to do that there's a screw right down here so there's a screw there there and over here you can pull those out and replace the fan and then the cable would just be routed out through these channels and then you can separate the shroud from the heatsink by disconnecting the screws right there so that is the XC and the other one is the SC ultra so that's the two EVGA 1650s that we have we're probably not going to look into sixteen fifties too much further they're not particularly interesting there's not a lot to learn because we already know the architecture at this point so it's just a matter of maybe looking at a 75 watt model if we get one but it's not a very high priority for us but that's the two EVGA cards if you would like to pick up the mod map that I worked on during
