OP's leaky capacitors are the CPU caps, they are actually required for console to function. It's only the clock capacitor which can be outright removed on most motherboards.
Thankfully this is a pretty easy fix and not remotely expensive. Xbox is going to be the Turbo Duo of the 6th generation as far as repairs go but it's worth it, it's a great box.
A good quality electrolytic cap is rated for 30 years but some of these trash Chinese ones used in Xboxes had a lifespan of more like 3 years. Even so it depends on a lot of factors and many can and are still working well past 30 years. But usually as anon said the big PSU caps are the most likely to fail as they run hot and are under a lot of stress.
Different electrolyte formulation. In the 80s, we figured out how to make water-based electrolyte solutions for caps in order to reduce the cost. This is fine, so long as you don't have a bad run (like with the plague) or set your cap somewhere so hot that the electrolyte begins to literally evaporate.
In olden days they had caps made of oil wrapped paper. These were rather different from the modern type of electrolytic and would tend to dry out from non-use. Regular application of power was necessary to keep them working.
well capacitors are based on hours of duration,sitting the capacitor next to the heat disipator was a bad idea,it was heating the capcitor all the time.
so bad design per se along shitty quality capacitor and you get why they don't last.
for example old capacitors of chine had 50k hours to 150k hours,japanese ones had a minimum 100k hours (loved the ibm new capacitors with over 300k hours of duration),then you had american ones with 5k hours to 20k hours top normally used on xbox.
hours
i will rather grab some unused ones from other electronics due to old capacitors made with 100k hours or 50k hours.
The reason they fail is due to how the xbox work (being next to heat disipator) this is similar to having a PC with the PSU right over the GPU and CPU so the heat will go straight to the PSU.

they're necessary to ensure stable, smooth power to the components in the console
God, PCs of that era were absolute shite in this regard. Bad capacitors everywhere. The worst of the worst was the Dell Optiplex GX270. Literally about 50% failure rate at the time.
Whenever I come across one I replace it rather than just leaving the holes unoccupied.

>haunted by my attempts to repair those caps only to mount one on backwards and destroy a perfectly good Xbox

I lost two PC motherboards to 2000s capacitor plague. And they were little caps not those big PSU ones which are the most likely to fail.
Those big electrolytics are easy to deal with
got lucky enough to get one that was in great condition, basically perfect other than the dead dvd drive
It won't be for long.

I've known boomers with guitar amps from the 70s that still have the original capacitors.

It's called a heatsink
The caps used in the Xbox were ether Nichicon or Sanyo, both are Japanese companies, moron.
All asians are the same.
No they aren't the Sanyo caps used in the Xbox were ultra low esr, the only thing comparable today are the polymer caps.
okay billy bob
Replace them with chemi-con 15000 hour caps APSC6R3ETD152MJB5S

hour
so I can replace them again in 2 years? no thanks
trivial fix
get a soldering iron and replacement caps.

The funny part is they're not even necessary. You can just pull them out and your electronics will work just fine.

Just move somewhere with clean energy
The bigger, the more useless, yeah. Rip em out with your teeth anon.
There's a few ee's around anon.
Replace them with ceramic caps
>ceramic caps
>here's your 1.5 picofarads don't use them all in one place kid
Kek, you think anyone on this board is smart enough to understand that joke?
explain pls
Ceramics don't use chemicals so they last basically forever but their capacitance is orders of magnitudes lower than electrolytic capacitors.
graphene will fix it
its an easy fix so whats the big deal?
>"Xbox" and "capacitor." Two words you never want to hear in the same sentence.
"I opened up my Xbox and replaced the faulty Capacitor"
Replace all the capacitors, add ram, a faster CPU then sell the Xbox for $800.
>a faster CPU
Anyone here actually done that?
Doing BGA soldering by hand seems like an absolutely massive pain in the ass
I have done 1ghz cpus with just hot air and a pre-heater, it's a lot of prep work but the soldering is pretty easy
these caps are for the clock right? do you have to replace them if you don't give a shit about the clock?
Those are CPU capacitors, they are needed for the Xbox to work.
clock cap is right at the front of the board
They are made to fail and should not exist.
I like these caps, easy to remove
I fricking hate the ones that are mounted to the board
This happened to me as a kid. One day it just wouldn't turn on anymore. Thankfully GameStop warranty so I just took it in and they gave me another.
