This thing is fucking huge

Probably a hot swappable power supply for a server or something similar

>>59238769
this, but not server, likely some work station like SGI Octane 2

Fuck these components are huge.

>470 micro farad, 450 V caps
>huge individually heat sunk transistors
>relays, fucking relays!

>>59239037
>fucking relays!
how would you turn it off and on programmatically without a relay?
Also google price back in the day for a SGI Octane

Not gonna lie OP, that's a score

Nice caps! I'm jealous!

>Prolly gonna take apart and salvage components
Livestream it, I wanna watch you kill yourself after you don't properly discharge the capacitors.

>>59239432
>>59238757

I wouldn't take it apart

It's way more useful in once piece

Next time you want to run something high power, you'll regret it

>>59239052
>touching huge caps with bare fingers
you're a retard who will meet Darwin in the near future.

>>59239657

It's only dangerous if you are a small child

anyone who isn't retarded knows to short the capacitors with a screwdriver. Big whoop.

>>59239722
>knows to short the capacitors with a screwdriver
confirmed for a retard. never touch electronics again.

This is a power supply for an industrial refrigeration unit. I can't believe you idots think it's for a server.

congrats, you're in possession of stolen property and providing evidence against the impending case against you

Discharge the capacitors with a resistor

dat ass

why is there a headphone jack? to hear the electricity?

>>59238790
Or a sizable network switch.

>>59239948
It's a workstation computer

>>59239948

So multiple content creators in an office setting can listen to their media without disturbing their coworkers. You know, shit employed adults do.

power supply out of an SGI Octane workstation as >>59239797 already said apparently
if it works don't fucking gut it, people will pay for those, shit I'd love a working one for mine

now find the rest of it and get yourself a real computer :^)

>>59238757
Give it back Jamal

>>59239853
there is resistance in a screwdriver

>>59239037
>let's just crack open this PSU

>>59239797
What were they thinking on that fan grill?

>>59243807
It's a handle to remove it, just like how the motherboard also has a handle. You don't open the case, you pull the components out the back.

They had to make it look rad so it'd match the rest of the computer

>>59243856
Shit probably hasn't been powered on in forever. As long as he's not a dumbass he'd probably be alright.

He should still fix it and undercut jewish resellers on Ebay so someone else can save a dead Octane though.

>>59238757
It's a PSU for an air conditioner.

Visual effects, virtual reality, CAD, modelling, just about anything 3D. Their graphics hardware was peerless for a long time, and just about every big-name studio had at least one or two of those boxes somewhere in the production process doing CGI work. They could also do editing just fine but I think they usually gave that work to Macs and Wintel boxes instead.

Scientific types loved them too for their architecture that was closer to a supercomputer than a typical desktop, they had insane memory bandwidth matched with decent FP performance that made them great for a lot of that kind of computing which usually dealt with solving memory-intensive problems using big data sets, plus they had a great operating system and development environment.

>>59246109
Oh, and they also saw a decent amount of use as instrument controllers, usually for stuff like medical imaging but I've also seen them used in semiconductor plants for whatever reason.

More like a server rack.

>>59239037
>>59239052
Those caps are storing mains voltage and may not have discharge resistors over them, so touching them isn't smart.

>>59239743
Using a screwdriver is a valid option.

>>59239853
Using a resistor is only a valid option if you get a properly rated resistor for it, which you probably won't. If it's under rated it will burn up, which is better than shocking yourself but still stupid.

>>59246482
>server rack
It's just a 650 W supply, probably barely even utilized by a typical config anyway. Maybe if you were running a decked to shit config with dual R10/R12Ks, dual MXI/MXE graphics boards and a loaded PCI cage or something.

>>59243685
Sure there is, but in terms of milliohms. Next time use a power resistor.

Holy fuck we had those when I was working at Eurocopter.

>some kind of high temp solder? My gun can't seem to melt it down for some reason. Is this a thing?

The case and fan I will keep off to the side. Will make an amazing project case for something.

>>59247801
That's a heavy board full of copper, your average 30 W iron will be about as effective at heating it as cooling a GTX480 by breathing at it.

OH MY GOD JC

>>59239080
>how would you turn it off and on programmatically without a relay?
Transistors? Are you retarded?

>>59239797
had these in the old graphics and cad work lab in my old mechanical engineering faculty
they threw em in trash containers in 2006 I think

>That faggot who destroyed an xbox devkit to make an case for pc

>>59248127
even worse was the guy who destroyed a pre-release testing xbox model, even rarer than a plain devkit model

>>59247801
Put some solder on your iron before you start to de-solder, will make it super easy. Litterally just have a massive blob.
Also try adding some solder first.

Some old tech got coated in a clear resin like material to stop/prevent shorts and human discharge resistor syndrome.

Also, it may use lead-free solder, which has a higher melting point then regular leaded solder.

If so, grab some lead-free solder and apply that to iron.

>>59247801

>He doesn't know about flux

Neck yourself

>>59248861
Carefully. Quick and dirty way is to short the terminals with a screwdriver. Make the fuck sure you are not touching any metal parts of the driver while you do it. Expect a decent spark.

Better way is to put a 10W 10k resistor across the terminals via some alligator leads for a few minutes.

>>59239037
>>59239052
They really spared no expense when they made that PSU. Wonder how much something like that would cost now.

>>59239743
electronics engineer here, why exactly is this not what to do?
haven't microwave repairmen been discharging the main giant capacitors in them with screwdrivers since the invention of the microwave?

>>59249868
Me >>59249779 again, Microwave caps are about the only ones I would put a dummy load across, typically a 100W globe. I have welded screwdrivers to those things before, they are a whole next level of fuck your day up.

What do you engineer?

>>59249893

your destruction shitlord

>>59249965
Thought so.

>>59249893
I'm in a commercial industry but work with much lower voltages
if somehow the solder got hot enough to reflow while discharging and your screwdriver got stuck to the solder I could see that, but worst case on these PSU caps is mains?
also it's not like touching the top of the cap is going to do anything, and I find it really hard to believe high end supplies like this wouldn't have discharge circuitry to begin with

>>59250015
I'm talking specifically about microwave caps with spade terminals. I've never had a PCB based cap light up hard enough to weld my driver in place.

Who the fuck cares, modern stuff is better anyway

I bet you that a i7 can smoke whatever device had that PSU
