Why you should NEVER buy a no-name power supply!

it's it's i wish i could put smell-o-vision because now there it goes again new build time ouch so pointy i mean it's pretty light but anyways you ever get to the end of your pc part picker list you're all ready to buy a new pc and you got a really good deal on the graphics card and you got the next level up but maybe you're spending a little bit more money on it than you thought you would you start getting to the end and you're like well i'm gonna need a few things you know sst you need a case i need a power supply and you start thinking maybe i could just skimp on the power supply a little bit i mean they're all good these days right it's 500 watts should be fine no no i did such a thing sort of for a you know more budget build that i would sell about this the coolmax technologies incorporated 500 watt power supply off new egg and oh my god is it ever a turd so today on the program i'm going to show you why you shouldn't be skimping on the power supply that's for sure and how i've come to discover i could i couldn't consciously put this in a build and sell it because it's really that bad so i don't know we're gonna fool around with it uh maybe even talk about why you should buy a good brand a power supply so cue an intro and then an ad spot and we'll be right back and we're gonna do things this cool max power supply should never be doing ever for fun [Music] the purebase 500 dx by be quiet is optimized for high cooling performance and is designed for those who seek low noise and high airflow all in one budget budget-friendly chassis the high airflow mesh intake allows the three included pure wings 2 140 millimeter fans to silently cool your pc components while the argb light strips at the front and interior of the case give your build that look you've been looking for more information on the purebase 500 dx in the description and thanks to be quiet for sponsoring this video so we've got this thing all set up here get her plugged in got the 2600k and i put the arctic uh with liquid freezer 2 on here it actually goes to 5 gigahertz now so the tdp on a 2600k is only 95 watts but when you overclock it it gets up near 250 from at least my watt meter here so that's not going to saturate this thing of course and i was trying to think of some combination of hardware but i'm actually legitimately worried about putting this on like my newer stuff um if i lost this this motherboard or this cpu or this graphics card it would be terrible but it would not be terrible like losing my uh 10 700k system or something like that or a rising system of lying around so this is the guinea pig for today 2600k five gigahertz and my fury x that has a uh fury uh the sapphire or xfx um cooler on it and that's a 275 watt tdp so we're definitely pushing the limits of things here like and so much so that i've got to do something really interesting here we've got to um use some molex connections because of course this only has one eight pin connector this 500 watt power supply so definitely not supposed to be doing what we're doing here today and i know a lot of you are going to be like don't do it timmy joe i could use that group that graphics card i could use that motherboard it's all for science guys so molex just to six pin one uh molex to six pin two i think yeah those are two different wires and then uh a sata on the other rail here we go uh there we go and uh there we go so we've got sat of the six pin that's plugged into a six pin to eight pin adapter that also needs uh these two molexes that go from that to a six pin that go into this so we're just feeding the power off of the uh you know sata rails and stuff like that on this power supply which is going to be detrimental for it i i've already made sure it kind of works so i don't anticipate two too many problems but uh we'll need a sata connector for my uh ssd here and then we'll get the thing fired on and we'll start playing around with it so give me a second here i'll get this all fired up and we'll see um just how many how many watts we're pulling here uh there we go all right pow road wait power on there we go all right so we got unigine heaven open here and we'll do a low resolution something it can uh it can handle because i don't think it's gonna handle much once we get going here um so uh 960 by 540 not full screen uh yeah we'll see will it run that low of a resolution um if not i'm probably gonna have to underclock the cpu from five gigahertz because i already kind of figured out that this thing just as it sits here there we go we're getting 450 and you hear it listen to this thing here i'll turn the music off in unigen it's it sounds like a vega graphics card with the coil whine it's not this that's making the noise it's this this has the worst coil noise coil wine i've ever heard out of a power supply it's it's actually crazy so what are we running 450 watts 450 watts 420 okay so dipping down a bit though let's step up the resolution here and uh see can we get this thing to blow up i wanted to i want to run it at like a pretty good it's starting to smell bad no word of a lie there's an electronic smell coming out of the power supply oh coil whine it is man jeebus all right i'll up the resolution here oh no she gaffed it wasn't even anywhere near 500 watts oh let's turn it back on beep here oh i'm gonna i'm gonna bring her down to 4.5 gigahertz i think that might be enough oh my goodness it stinks all right back into windows at 4.8 gigahertz let's see can we run it might just be the graphics card and the way i have it set up here it might not matter how much i down clock the cpu but we'll see what happens loading it up again at that real low resolution see the power coming out of the wall is now 405 okay so it's definitely a lot lower but this thing's making all kinds of noise again we're 430 watts okay i'll see how long it'll actually last with this going on 400 watts now not doing too bad can we up the resolution maybe we'll just we'll just go straight to 1080p see if it'll do it would you want that in your system [Music] it shuts off at 1080p right away 720p how many watts 489 500 watts what the hell yeah it did not like that we were over 500 i don't know what was going on there we were over 500 right away i will blow this power supply up even if it's smart enough to shut itself off when it's doing stupid stuff all right we're at a much lower 75 watts 72 watts idle on the desktop here that's gotta be better it's i wish i could put smell-o-vision because oh there it goes again it really stinks after a while something's getting too hot in there okay so i've uh downloaded msi afterburner and i'm going to underclock the video card a little bit this will give us some granular control to get the wattage we want to see on the screen here we're at 444 watts there power supply is smelling worse than ever yep this seems like a decent place to leave it so i'm gonna let this happen i'll leave the cameras rolling just in case it explodes 1000 megahertz pretty good coil wine 425 watts 440 so she's staying under 450 watts that should be good 468 watts why is it go so high 70 78 78 on that heatsink it keeps getting hotter you hear that you hear that i blew it up and it can't even start anymore do you hear the crackling oh it's powering the computer back on it's crackling it's probably so bad it smells very bad in here it's crackling i didn't think that would be the result of this okay keep in mind this power supply is brand new all i ever did was use it one time to test the 10 900k system just to grab a quick power supply just to see if it would boot with like no video card or anything like that i wasn't and i turned it on and once i got you know just kept making this noise once i did get stuff working it's like there's this is the worst power supply i've ever heard of full bore is it dead shut it off for a second see if it'll nope the switch won't even go off anymore the switch is like melting or something the switch melted whoo it it's dead i'll let it sit there for a second but i think it's actually dead i killed it in like 45 minutes it's dead it's totally dead all right i want to take it apart that's so loud i guess i should make sure that this the system's not dead power on now that's a power supply nice corsair tx 750 from a few years back it's a little loud but it certainly isn't screaming and the computer turns on okay let's just make sure it gets into windows load back into five gigahertz here and we'll uh see with this thing running full tilt what kind of watts we really get out of the system with a proper power supply i just want to see you know what the difference is maybe this is more efficient and it will actually run at a lower wattage because it knows what it's doing i don't know we'll see all right so i set everything back up with this corsair tx750 power supply it's actually the power supply that originally ran this 2600 and motherboard and everything i kind of bought the whole lot from the guy really good power supply i got a good deal on it i think i paid 70 dollars for it so for 750 watts like yeah and it's clean but hooked up on this thing i overclocked the cpu back to five gigahertz i overclocked the uh graphics card uh 25 megahertz higher to 11 10.75 that's 25 over its stock but remember we were running it at like 975 to get that other power supply to start exploding and what's really interesting is look at the watts that it's running right now 300 and what uh 375 max maybe it's like 325 to 375 it never breaks 400 doing even more work than the system was with this crappy power supply oh my god it's still actually a little bit warm that's crazy i'm gonna they can see it's all working i'm glad that my didn't blow up uh you know this set of hardware that would have been kind of gross but uh you know never hit never hit while i hit 400 watts there just me closing it so but it wasn't going anywhere near the like 450 watts 475 watts this thing was reading with lower overclock settings than i just had on this this thing so i'm gonna go ahead and get this all cleared out and then i just want to open up the power supply and see what it looks like inside this thing you know we'll just check it out all right open it up you know it doesn't look too too bad nope there isn't a whole lot of evidence as to what went on in here i do have a power supply tester even though it's really just a measure of does it work or not just says fail yeah it's done that's awesome so no evidence except for the clickily clacks when this thing tries to so this actually did test the power supply that's pretty sweet i wasted 50 bucks on this so what is the conclusion what is the moral of the story always by a name brand power supply there are lower quality versions of 500 600 watt power supplies from thermaltake corsair cooler master stuff like that it is always better to buy a name brand power supply they're not gonna sell something like this because it will really sully their name a lot of them have like at least some sort of 80 plus rating on them you know go with something like that even if it's gonna cost you twenty dollars more or fifteen dollars more because cool max or anything like i mean i've seen these in pre-builds before man they fail they just fail imagine a year's worth of dust in this and you're putting a pretty heavy load on it oh man it's just gonna spell disaster it was literally sparking itself and i know i wasn't using it the way it was intended uh you know i had the molex and the sata branching off to power a graphics card this thing had no business trying to power but at the same time imagine you used all of the molex and uh the sat on this for hard drives and then you had like a you know just a lower end core i5 or something you know you're using it as a nas or something like that there's all the connectors on there you think you could use them but no i i would have wager you should really never use this power supply maybe you could get away with using it in some like office just you know onboard graphics situation uh and you'd get away with it and it would last forever but uh any sort of graphics card any sort of load on this thing there's no way it's lasting a year and it could take your components with it so that's the morale of story buy a name brand power supply like from our sponsor be quiet they make good power supplies i'm out watching me joe instagram and twitter i hope you'd enjoyed watching me blow up a power supply basically just set 60 on fire by the time taxes and shipping were involved and uh yeah i i destroyed it it's broken now have a good day guys see you later always by name brand power supplies [Music]
