Does one really save money? given that they can get bulk pricing.

Who makes the best pre-built desktop PC systems; I had in mind

Lenovo
HP
Dell
Acer

and am not at all keen on the use of non-standardized parts or systems
that are glued shut, so dropped...

Does the noise certification take into account the frequency? the human ear has different sensitivities at different frequencies, and there is also the trick to spread the noise over several...

Concerning coil whine, why are not more inductors potted

* Cost?

* Cooling issues?

A small camping stove to make coffee might be the best bet.

You are not concerned about material being in the cloud, and so vulnerable to access by hackers?

Would this be sleeve, like

Ceramica - Ceramic Bearing Fans (ceramicafans.com)

or ball?

Perhaps someone here can tell us how good is the backup feature in Windows 10; of course even this isn't good enough against a fire.

I really wanted a fan-less video card and the GT 1030 fit that bill.

The default options are

1920 x 1080 and frame rate limited to 30

Also the problem that cores can age

My Son's computer is way below the minimum for Ancestors: the Human Odyssey; it needed a 3GB video card (his was only 2GB), but it was on sale for $5 so I took the risk. Plays wonderfully.

Thanks, I thought the ripple was at the switching frequency.

Seems to me that mains ripple could be eliminated with better switch mode feedback rather than larger capacitors.

I meant a water pump for a house boiler, that the winding insulation can take it.

Didn't know the transformer core material had such a low temperature sensitivity; this is the Curie point?

The windings of a heating system pump probably run at above 100°C and some electronics can run at 250°C

What are high temperature electronics? - TWI (twi-global.com)

Gallium Nitride is up there...

Why don't PC power supplies use multi-phase? that would reduce the smoothing burden.

Inductance would reduce loses from using capacitors alone.

Primary caps rarely fail; it is strange that you are replacing them.

Is it possible that the future moves to capacitive based voltage transformation rather than inductive? by this I mean capacitors as part of the voltage transformation, and not just for smoothing.

I'm not about to purchase a 3 star power supply.

Are Ong Hua fans the same as Hong Hua?

When almost 30% of the reviews are 1 star I get concerned.

It's a trade off and not as simple as one thing is good no matter what.

Another issue with low ESR capacitors
Notes on the Troubleshooting and Repair of Small Switchmode Power Supplies...

Water based electrolytes may be used for lower ESR, but this could lower the maximum operating temperature and life. What is higher RC?

As the Guru points out, its not so simple



Anyhow, I'm...

What is 'chassis certification' and why is it needed on top of noise level certification?

Low ESR is a must for the secondary capacitors, one can't just use standard electrolytic capacitors. Temperature is not an issue if one designs things right, namely to have the capacitors sit in the...
