The "ugly case" is actually really great looking. Especially compared to those boring black cases.

[@MarcoGPUtuber]

It's not ugly, it's aesthetically challenged.

[@tony359]

It must be the lighting ;)

[@wimwiddershins]

Need a few beers, then it will start to look, ok.

[@horusfalcon]

That's a thermosetting plastic heat pad on that Athlon. They are actually very good in applications where high heat tends to make paste migrate. At initial powerup after application, the material melts, flows, and fills voids between the sink and the CPU die. This one was misapplied. It can be completely removed by carefully scraping it up, but be careful of the SMDs on the CPU board. I have a Dell Dimension 3000, which is somewhat later but very similar to the 2400 you have here. They are beastly rugged little machines, and can be put to good use with MS-DOS, WinXP, and Linux. Enjoy these finds and make good use of them! I like your style, man. Have a subscription!

[@tony359]

ah interesting. I wonder whether I should have warmed it up a bit before attempting to remove it? Interesting. Oh yes, the Dell is very rugged. I just don't like it personally but it's a nice well-built machine. THanks for watching!

[@DjMarik78]

Hi Tony!, All cheap half bridge ATX power supplies and most of the good ones ( if not all of them as well ), have the controller IC on the secondary side! That's mandatory because they all use a driver transformer, both for controlling the power transistors, and for current measuring ( it's a combination between a driver and a current transformer ), it uses one turn in series with the primary of the main transformer to measure current. You did not say what controller is on the psu but judging from the fac that you mentioned it has it's supply voltage on pin 12, i am guessing it's a variant of TL494 or KA7500 ( most ATX units that uses half bridge as the main converter, are based on this IC, it's very simple to use and very flexible, and quite suited for a ATX power supply. If it is 494/7500 and you measure 7V on pin 12 then it cannot work, it cannot start due to it's UVLO. When you get an ATX power supply you are not sure of, you never just power it up and see what it does! You always open it up and after dust cleaning, take the board out, measure the fuse, if it's gone then most likely so are the power transistors ( either on the main converter or on the auxiliary unit ). So, you then measure all the power transistor, both on the half bridge side and on the auxiliary flyback. If all of them are ok then most likely the supply is easy to fix, it would only have capacitor issues. Most of the times, the auxiliary output capacitor dies out, and that kills the auxiliary converter, thus killing the entire unit. So after all measuring and checking and part replacing, the first thing you do is check if you have the 5Vsb output. If it is there, then you check if the controller IC receives it's proper voltage ( for 494/7500 you should read just over 12V on pin 12, sometimes a bit more is just fine ). Only after all of this, you cand put the green wire to ground thus try to power the main supply. PS: ATX power supplies are my thing, i have played and experienced with hundreds of them, cheap of expensive, that is why i felt i needed to say something here. All the best!

[@tony359]

Thank you so much for the detailed comment - I'd like to take a look at that PSU anyways so I'll keep your comment in mind when I do! Thanks for watching!

[@DjMarik78]

@@tony359 you are welcomed as always! If you do try to fix the PSU, then if you find that the half bridge's BJT's power transistors are gone then you should also check the driver transistors on the secondary side of the driver transformer ( the EE19 or something like that, near the main transformer ). That pulse transformer is driven by 2 small BJT's ( usually C945 ), sometimes when the main power BJT's fail they do affect the two driver transistors, and if any of them is damaged in any way, then by default without any other checking, you change the controller IC with another new or known to be working one. The driver transistors are always measured out of the board, either with the component tester or with the multimeter on the diode function ( i still chose the multimeter way, it's more accurate and trustworthy ). After taking out the driver transistors you always measure the four 4148 diodes connected to them, both the CE ones and the emitter series ones, just to be sure, because sometimes they do fail and you find the supply does not work even after replacing the transistors. And, of course, you replace by default all the electrolytic caps, either with new ones, or with good tested ones. In fact, the two 10uF ( or something like that ), near the bases of the power BJT's on the primary side, is mandatory to be replaced with new ones, they often fail and... Good luck, and let us know if you do succeed in fixing that ATX power supply! All the best! PS: I told you, i always watch all your vids, religiously i might say 😂

[@tony359]

thanks again - if I try to fix that, it'll be on camera! Magic Smoke is better when on camera! ;)

[@DjMarik78]

@@tony359 Indeed, sometimes the magic smoke release is quite spectacular :))

[@tony359]

Hi! I'm trying to fix the PSU - can I pick your brain? As you suggested, I only have 6/6.5V on pin 12 of the 494 (you guessed it right). I scoped it and it's only "pulses" at around 50KHz. I found what looks like the capacitor for that line, 2.2uF. I removed it, the capacitance tested ok but the ESR was 18Ohms. I replaced it with a 3.3uF (I don't have a 2.2 right now) but nothing changed, I still have pulses on pin 12. I do have 5.1VSB. Right now the PSU is idle so I guess there is no point in worrying about anything else but I haven't found shorts or so. Any ideas? Is VCC for pin 12 derived from the same little transformer which supplies 5VSB? Thanks for your help!

[@tony359]

ahah indeed, many have said the same :) Thank you!

[@FireballXL55]

The main failure with ATX PSU's is the 5VSB rail the cap for it I believe I saw with a bulge in it. This is why people very often say my computer was working fine until we had a power cut. The cap is on the output of the small transformer and feeds the IC you looked at but you did not look at the ripple on it's supply. But as you say, it's not worth the time other than for curiosity.

[@tony359]

absolutely but I think I'd like to give that a go on a separate video - it's really not worth but I'm curious. I'll keep your suggestion in mind, thanks!

[@bitsundbolts]

I like the Radeon 7000 due to its PCI connector - it will be quite useful for socket 7 systems. I don't mind the aesthetics of the first case - it is something a bit different from the other "office" PCs. Although, I do like the overall IBM package. I am not a fan of the DELL machine. Overall, you got a lot for 5 pounds! Nice video Tony!

Really do love these IBM machines. I daily drive an old ThinkCentre A60 which was a late '08 version and was surprisingly Socket AM3, and bares both Lenovo and IBM's logo on the front bezel. It came with a Phenom, but I was successfully able to modify the Phoenix BIOS to support the AMD FX series (required some AGESA module swaps). With VRM's capable of *just* handling the 8370, that's what I went with (no overclocking since the BIOS has no controls for it). Surprisingly stable, it's never really crashed. Runs Windows 11 with a 1080 Ti. Both retro and modern, a kind of bridge machine from a bygone era and still able to handle most modern software. I did however replace the HD with an SSD, and replaced the LED for the SSD, card reader, and optical drive all with yellow LED's, as it reminds me of PS/2's which also had yellow activity LED's, really just the only cosmetic touch I did to it, otherwise it looks stock.

It was the same with Slot 1 and socket 370 boards. Some would toast but the more expensive models had their own sensors. Boards that had SiS chipsets were usually the cheapest ones. Also those old boards that got those sensors depend on the RAM somehow because if there is no RAM inserted the sensor will not work either and you can kill the processor if there is no heatsink on it but if the RAM is inserted they will quickly shut off.

[@arnlol]

I did that same mistake over a decade ago with one of these AMD CPUs putting the heatsink improperly. CPU died instantly, I was confused why the PC wouldn’t POST. I also had one where the corners got chipped, and it was extremely unstable and did all kind of random strange stuff due to the damage. Back then these machines were basically worthless and I had gotten all that stuff for free so I didn’t really care that much. One of the cool things about modern PCs is that is is very difficult to actually mess it up, if you power on a CPU with no heatsink it will just throttle and/or shut down. Back then the CPUs would just burn to death.

[@tony359]

Yes, there are more sensors than core nowadays! Back then you needed to know what you were doing. I kind of remember a system which was supposed to protect itself from overtemperatures - but the sensors would not come up online until the board had posted so the CPU could toast in those few seconds... Interesting times!

[@gorjy9610]

These old PSUs are junk, but... :)) Old platforms require more power on 5V rail than any new, modern and high quality PSU is made for. Also, anything made in the last cca 10 years lack negative rails needed for some old soundcards. So some of these junk PSUs can be actually useful. Of course full recap is needed as most of them was from cap plague era (high voltage caps also need to be replaced). Btw, in case of this one problem is voltage for the main IC. It need over 15V to start (forget about datasheet, it can be used in many things and for some use cases 7-8V is probably enough but in a PC PSU it need more), there is cap next to it (usually 22/47uf@50V) that need to be replaced. But as I said all of them should be replaced if you decide to fix it.

[@tony359]

Very good point, I was thinking already to try to repair it - I didn't notice the -5V though @bitundbolts made a -5V adaptor which is very handy. Thanks about the heads up about the voltage!

The Sempron got *Semproasted* but I'm glad that *ahem* "WinFast" motherboard still works. These systems are a bit gross, I appreciate the need for disposable gloves.

[@SobieRobie]

Geforce 256 DDR was even a little bit faster that GF2MX400 so 7000 is really low end but... thanks PCI connector you can use it with S7 motherboards with now AGP slots and then this card can can be really useful.

[@tony359]

Yes indeed! Remember my "PC update from hell"? I would have loved to have a PCI card to rule out the AGP quickness :)

[@smada36]

Oh no! Foxconn. I have a Foxconn mobo from a prebuilt I bought brand new before I knew anything about computers. It's an H77M and I replaced it with an MSI Z77 after I got fed up with it fighting me every step of the way. All I did was upgrade the graphics card, and even putting the original card back, it still had gremlins in the system from then on. The BIOS would do some very weird things, like if you were using Display Port, you couldn't even enter the BIOS. I tried with a third graphics card and it was still the same, so I put the second graphics card back, and it wouldn't even post. Nothing to do with drivers because it wasn't even getting to an operating system, but resetting the BIOS did nothing either. A very odd problem and hard to explain it to people to get help. Being a prebuilt it has a seller specific BIOS and flashing the chip to anything else just made a dead system. Now all the websites are gone so finding anything for the motherboard is a fight in itself. Not a fan of Foxconn 😬

[@tony359]

sounds like a nightmare - similar to what I recently had when I went upgrading my Retro Machine - two weeks of gremlins! The video is on the channel if you fancy seeing me struggling with all sort of issues :) Thanks for watching!

[@collectingretrotech]

I can’t see clearly in the videos but have you been trying to start up these motherboards without the CPU 4pin power cable plugged in?!

[@tony359]

I'm sure at least one doesn't have that - anyways the Winfast works :)

[@Shmbler]

I'd not throw away the cheapo ATX PSU. It has -5V, which more modern ones typically don't provide anymore. And there are early ATX boards that do require -5V.

[@tony359]

You're right, others have mentioned that. I won't - I'll make a video where I try to fix it! Thanks for that!

[@Shmbler]

@@tony359 It's the same thing with the 6 pin AUX connector. They used to be omnipresent in ATX PSUs around 2000. But when I recently got two boards that needed them, I only found a single one in my stash of ~30 old PSUs.

[@tony359]

@@Shmbler Is that white connector that looks like an AT PSU main connector? I saw that and was wondering what that was. Cool, so I guess a fixing session is due for that PSU :)

[@Shmbler]

@@tony359 Yes :-)

normaly it boots with agp ,and then the inbuild grapics kard you going for a pci card then it can be hard to find but can also be a setup in bios

I use to Dumpster dive got some ok hardware highest was 6600K with 8Gb Ram GTX 780 this was few months back in london it still play todays Games on it, but it seems people and companies throw it away because once something reaches near 10 years they either recycle or bin it such a shame many families haven't even got a basic machine should be donated

[@tony359]

a shame indeed - companies usually don't do that because 1. it takes too much time 2. there is liability involved: if you take home an object and you get hurt by the object (or it catches fire etc) then you could sue them. I know of a business purchasing and opening appliances to make sure their technology was not being used inside - those appliances were then immediately DISPOSED OF because "tampered with by an unauthorised person" hence they were not "safe" anymore.

[@asanjuas]

if there is a micro atx mainboard first test with the integrated video and see if posts if not maybe a mainboard problem test the processor in another mainboard and see if it works.

[@SobieRobie]

OK, I was too fast with the comment and I didn't win ;) BTW Winfast is a name for Leadtek products. These cards were quite good, I did sold a lot o Rivas from Leadtek back in the days.

[@tony359]

ahah - no worries, I do that too very often! Great to hear then!

[@edgkenny]

The first CPU was probably an AMD Sempron 2400+ (1667 MHz).

[@tony359]

I think you are right, I need to check that. RIP :)

[@cybergarri]

be aware that this athlon motherboard need the power in the 5v rail and don't work with modern psu if you check the cheap psu in the video you can si 35A in 5v / 17A in 12v, there is a way to convert to 12v with a mod I saw in youtube and looked fun to do sadly my old motherboard was dead and I couden't try. By the way did remember some mb with chipset sis had the problem that went they shoutdown bad the pc the mb reseted the FSB to 100 and the people end using that athlon slower than default (133-200 fsb) a shame becouse thats chipset were cheep and reliable

[@tony359]

yes I remember those CPUs were fussy with the PSU! I guess it would not work with that small one I used for testing! Weird about the SIS chips - though my Motherboard (B550 AMD) also resets the whole thing with BIOS updates. If you don't realise, your RAM will run at lower speed (I normally enable whatever is called to make it run faster)

[@blakecasimir]

Loving this mid 00s archaeology. Don't bother with that Q-Tec PSU it is utter garbage! This era of system isn't super interesting any more imho. Even though I have nostalgia for that era, the lack of ISA means they are less compatible with DOS games, and the lack of CPU perf means a Core 2 XP build would run rings arounnd them. Thoroughly enjoyed the video though Tony.

[@djdoo]

For the poor Sempron CPU if you look closely someone must have tried to put new paste on the die and placed the heatsink the wrong way around not contacting and burning the CPU probably after a minute or 2. Ask me how I know as Americans say... The IBM case looks wonderfull and very modern! Also 2Gigs of Corsair 400 RAM is a nice plus, too bad you cannot use the Athlon XP, which was way better, in that case and you have to stick with that boring Celeron. The Dell case looks as boring as its internal parts, completely uninteresting as most of the Dell PCs... The black generic case is cheap but looks OK The white "Ugly" one looks so strange for its era that I can call it interesting as a design and definetely not ugly I believe you were harsh on that poor old case. Winfast is a nice motherboard and being Full ATX is a plus and has AGP and CNR which is a pretty rare slot. Gigabyte is a standard MB Very nice video Tony as always, cheers from Grecia. Jim Great 5 pounds investment!

[@tony359]

Hello - thank you! Yes, maybe I was a bit harsh with that poor case! It was cheap though, really thin metal, very light. And too big :) Thanks for watching!
