Well, I am afraid I am still confused. You want the inserted plug (which you don't have yet) to physically move a contact in a socket (which you don't have yet either) until it contacts a 2nd contact...

That's an odd question. There are probably many 1000s!!!! Most DC connections are 2 wire and many low voltage AC are two wire. Speakers, microphone, even your everyday table lamp uses 2 wire...

. It "throws" two circuits - hence SPDT. A power indicator should not be lit if power is off.

Yes, you need a rectifier. But a tiny diode can easily fit inside that switch.

A "rocket" switch? What? It takes off when you flip it??? ;) I am assuming you meant "rocker" (really "toggle") switch?

You cannot assume the voltages are just DC just by looking at it, or just...

Well, I'm am not sure the purpose of this post, but sadly, it is not accurate.

Sorry, but that is not correct at all. An electric motor (any motor, not just electric) is used to convert energy...

Well, you can tell by the last line in my sig my position on heat - so I agree about cheap, hot running PSUs.

Overtaxed is a different issue, however, as that is the computer assembler's (or...

Decades? That would be nice, but that is not realistic as a "norm". While I agree fan and cap failures are more common, I would also note I have had a fair share of rectifier failures too.

Because the rest of the components inside are 5 years old too. While 5 may not be old, it is not new either.

By doing the labor yourself, you will save some money - but if you factor in the value...

"Only"??? Well, that's BS! Clearly by a clueless person - or a marketing/PR weenie trying to put a favorable "spin" on the storyline.

@bord - Are you considering recapping just for the experience or challenge? I ask because I don't think recapping a 5 year old PSU would be very cost effective.

Yeah, compared to other ESR testers, I agree the price is "cheap". Plus it has just two "big" buttons and auto-range sensing with no knobs to set. With my eyes at my age, that's a very good thing! ;)

Considering the Honeytek can be found for under $20, not sure I would call the ESR70 "cheap". But I think the price can be justified if you have a need to test caps frequently.

That said,...

Sure it cares - very much. But a quality PSU is likely to be more tolerant than $20 no-name generic.

BTW - a 1200W PSU? That is likely WAY OVERKILL - unless you are running 2 (or 3) MONSTER...

I far as I know, it has been contested, perhaps, but not disproved. But that's really a moot point as again, movies, as shown via projectors at movie theaters, are typically at 24FPS. I note Peter...

I think "10 years+" is a fair statement - at least for a "good" UPS. That said, I have an old APC UPS that is pushing 20 years old. But I also recent tossed an APC UPS that gave out after 6.

The APC SMC 1500 would be the better UPS primarily because the output waveform is a true sinewave. And if money were no object, that is what I would opt for.

But you really don't need that...
