Maybe a better question would be ... was it that hard to add a 20 cent LDO regulator inside the thing, to convert 5v to 3.3v?

You'd make your product more compatible for a minimum of an investment.

Sigh...

Capacitance of the "hold cap" or primary capacitor or high voltage capacitor is supposed to be big enough to sustain the power supply at its maximum output for at least one AC cycle (1/60...

It's in a sealed package... it can last months, maybe more. But once you open it, it should be used soon.

Once applied it needs about 15-20 minutes at ambient temperature to skin over (form a...

Sadly, there was a lot of controversy about this video... the guy faked the thefts ... all of the recorded stuff is with friends stealing the package from his house.

He claims the package was...

You can unscrew the case, and solder wires where the 12v and ground wires are ... or just splice them to exising 12v and ground wires.

Here's an example adapter cable you can buy for 3.5$ : ...

In a lot of circuits, the leads must be as close as possible because the leads can affect the circuit.
The extra wire adds resistance to the circuit and can even add inductance (super small value,...

Feels like a "just ok" 350-450w power supply ... the three fan thing makes me think of PC Power and Cooling power supplies but i guess in the past there were multiple manufacturers using two fans.
...

Estimate how much your computer will require, then add around 20-30% (just in case you'll add hard drives, or a more powerful/power hungry processor or video card)

If that's still below 400-500w,...

46c-50c ambient temperature is not a significant amount, the only components that may have issues with this are mechanical drives. Anything else can handle such temperatures.

If they boot the...

You could use a desoldering gun. Even with desoldering gun, ADD solder to the joints. Then apply desoldering gun, and wiggle the tip (make circles around the lead) until the solder is melted and suck...

SSR-430ST Bronze should be fine, though it's a bit light on 3.3v and 5v - for the boards that use 12v to power CPU it would be fine.
EVGA W1 is kinda crap, BR is a bit better if I remember...

There's also the issue of Intel pushing Thunderbolt into USB 4.0 which would further complicate things and require companies to redesign chips
...

Maybe it's a poor translation of "industrial power supply" ... maybe it's designed for higher temperature range, maybe has some dust filters ...

Outdated topology with very poor efficiency ... let's say around 70-75% efficiency at 50-100w where most computers idle in desktop
You can tell it's old design by presence of voltage switch...

They're 25$ on Newegg, after 15$ mail-in rebate... not a bad psu for 25$, for cheap low end systems. Newegg link : https://www.newegg.com/Product/Product.aspx?Item=N82E16817151226

The video card may not start without both connectors plugged in.

Yes, the video card is power hungry when you're gaming.

The average maximum power consumption is 245w, with peaks up to 300w...

Modern power supplies should not have voltage on the heatsinks. I had older designs that had high voltage on the main heatsink.

These days most power supplies have mica or other insulators...

and how efficient would the 90v AC .. 250v AC to 12v be?
how efficient would conversion from 12v to 400..450v be? how much current you pull from those caps?
also supercaps often have low max temps,...

All modern processors will survive if you start the pc without a cooler.

Back then, AMD processors burnt out because they had no metal heat spreader on them and because they had fewer internal...

If you upgrade the CPU, you're gonna have to upgrade the motherboard as well. Also, both CPUs would require a good cooler, ideally water based.

I don't see how you say you're gonna pick one cpu...

I should add, as long as it's feedback / bug report time, the url rewrite is kind of bad as there's still the ? in the url ... removal is done for seo purposes and easier indexing by search engines,...

The website tells the browser that the language code is ISO-8859-1 but then the forum sends everything using UTF-8.

Have to agree.

Try something like PT Sans : https://fonts.google.com/specimen/PT+Sans (play with the default size)
Even Roboto looks better: https://fonts.google.com/specimen/Roboto

You'd still need 5v for sata but they could make cable strips with dc-dc converter on them
You could have a bunch of 2x2 connectors (2x12v and 2xgnd) ...
