My favorite example of this sort of nonsense was an advertising image I saw when I was looking for a digital microscope. Had some very tiny wires to solder and wanted to get a feel for prices.

And then there is this classic

I immediately thought of this one.

Just listening to the AC DC via soldering iron. Tbh when IA art becomes super believable this is what IA art is gonna look like.

After working in IT since 1999, I can count on my dads lefthand fingers the times I've had to solder a graphics card.

PS: My dad lost his left arm in 1996

[–] ooterness@lemmy.world 7 points 2 years ago (2 children)

He's not using the soldering iron per se, he's threatening to use it. "Nice memory chip you got there, shame if something happened to it."

You don't need it, because thanks to the two power supplies you can run your CPU at double speed!

There's a few tricks you can do in overclocking where you replace shunt resistors. It bypasses power limit protections by making the board think it's drawing less power than it is.

That and replacing dead caps is about the only reason to touch a soldering iron to a GPU.

Only time I manually overclocket a PC was with a leaded pencil in the good ole days of AMD Thunderbird

When I worked at a computer shop if I thought a power supply was iffy I would plug my backup in outside of the case just like that. Was great for diagnosis.

I would also solder some laptops, dc jacks mostly. But not like that.

If you've never run a computer with a PSU hanging out the side powering your extra hard drives have you even lived?

[–] Hamartiogonic@sopuli.xyz 3 points 2 years ago

I’ve used an extra PSU to power a graphics card. Things weren’t properly compatible, so I had to improvise a bit.

When you start the computer, you also need to use a paper clip to start the second PSU, because otherwise the graphics card will scream in terror until you give it the power it demands. It was probably the most ghetto style computer I’ve ever had.

There was a point around the early 2000s where having a second PSU was a possibility for overclocking. I've still got my modified case with a second PSU in the optical drive bays.

From memory, the Pentium 4 would draw something like 120w, the hard drives would draw a bit more, then the graphics card would, and if you were pushing your limits, you'd have loads of fans and maybe a peltier cooler. Now known to be massively inefficient, we thought they were great at the time.

On top of that, you could only usually get low powered PSUs at the time. 350w and 500w were the norm, and you could get 650w if you were lucky. 800w were seen in magazines, but you'd have to remortgage your parents house to get one.

[–] frezik@midwest.social 7 points 2 years ago

And those 350W ones might catch fire if you tried to pull more than 200W. There's an old video of a 300W supply being pulled at its max rating, and it was taking 900W from the wall. That's 600W it's turning into heat.

Johnnyguru may have singlehandedly fixed the whole PSU market. There was so much garbage back then, and few other places were giving them the tests they needed.

[–] Rai@lemmy.dbzer0.com 4 points 2 years ago

I have a server with two PSUs… hahaha

Redundancy though, it’s not a standard desktop

[–] zod000@lemmy.ml 2 points 2 years ago

Spot on. I used to run a second PSU for my peltier cooling back in those days when overclocking. PSUs were also not nearly as powerful as they are now. 300w was average.

[–] Matombo@feddit.de 13 points 2 years ago

At least he is not touching the ouchy part of the soldering iron unlick a famos other stock footage

[–] ThatFembyWho@lemmy.blahaj.zone 12 points 2 years ago* (last edited 2 years ago)

Excellent form, your non-soldering hand must have good contact with the PCB. Then you wave the iron like a wand, and incant "solderus fluxus", pay special attention to your pronunciation, and try not to blink as you envision the tiny components rearranging before you.

[–] fox2263@lemmy.world 9 points 2 years ago (1 children)

I too like to solder a graphics card while holding it in the air. Helps with precision.

[–] DigitalFrank@lemmy.world 2 points 2 years ago (1 children)

Do you also like to solder on the component side of the board?

[–] Antimoon51@lemmy.world 9 points 2 years ago (1 children)

Tbf, I once ran a PC with two PSUs at the same time, because I suspected one to overload, but had no 2nd powerfull enough to run the whole system. It kinda worked, bjt the system broke down due to other reasons...

[–] Wootz@lemmy.world 2 points 2 years ago

I bought a Cooler Master Stacker 810 back in 07 almost exclusively because it could fit two PSUs. All the cool kids over at XtremeSystems were doing so teenage me thought I should as well.

I never got around to needing another PSU, but I did learn to jump start an ATX PSU, and I still have the case.

[–] Anticorp@lemmy.world 9 points 2 years ago (1 children)

What is he even supposed to be doing? Just melting circuits with a soldering iron like Phoebe's brother?

[–] slazer2au@lemmy.world 8 points 2 years ago (2 children)

Seen enough Dawid Does Tech Stuff to know the sign of a good bodge job is a second psu.

Also, yay for holding the soldering iron correctly.

I dont see your point since one of them is just sitting on the bench.

[–] MrPoopyButthole@lemm.ee 7 points 2 years ago

Maybe they just have a 4090

[–] xia@lemmy.sdf.org 6 points 2 years ago

I don't always hold a soldering iron, but when i do... i hold it like a baseball bat.

And you thought dual cpu's was innovation!

More power equals more fast, everyone knows this.

[–] lightnsfw@reddthat.com 4 points 2 years ago

I had a PSU blow out in my server once and troubleshooting looked almost exactly like this. Minus the guy with the soldering iron.

[–] hips_and_nips@lemmy.world 4 points 2 years ago* (last edited 2 years ago)

Yeah, my two main servers use redundant power supplies, my AI GPU server has no less then five, non-redundant power supplies, and my partner’s and my gaming rigs have two each, one for the damn GPUs and one for the rest of the system.

[–] Kanda@reddthat.com 4 points 2 years ago

I have daisy chained two PSUs to power a motherboard with 4 GPUs. Would recommend buying appropriate gear unless you like the smell of melted electrics

[–] Endorkend@kbin.social 3 points 2 years ago (1 children)

The Threadripper rig I'm building has a mainboard with plugs for 2 power supplies.

[–] Albbi@lemmy.ca 2 points 2 years ago (1 children)

Dual redundant? Or does it actually need that much power?

[–] Endorkend@kbin.social 3 points 2 years ago

Doesn't need it, the CPU is only 350W TDP for the 96 core variant, but a rig like that tends to also be loaded with 2-4 GPUs for compute workloads and a fuckton of ECC memory, which tends to use (far) more power than standard dimms.

I'm installing a (1+1 redundant) 1200W PSU for now, as I initially will only have a single GPU and a single DIMM per memory channel to do the platform validation.

In your typical gaming setup, you could perfectly use a single PSU, even an 850W one would probably do just fine as there's no games that'll 100% all the cores anyway and threadripper cores are ludicrously well optimized for power, especially compared to anything Intel offers in the desktop, workstation or server market.

[–] mceldritch@lemmy.world 2 points 2 years ago

I have 3 of that exact video card.

[–] bionicjoey@lemmy.ca 2 points 2 years ago

I run a server with 2 PSUs. If one craps out, the other can keep things running

[–] dotslashme 2 points 2 years ago

To be fair, literally everything in that picture is bizarre or weird.

I have that exact GPU in my closet.

[–] Buddahriffic@lemmy.world 2 points 2 years ago

Is that a Radeon 9500? 9300 maybe? Cooler and board colour looks exactly like the 9800 but the board is smaller.
