I assume a heavy dose of cargo culting and ass pulls is necessary?
You could say that.
You overestimate (550W total is fine in your case) and don't worry about it unless something happens (too bad that it did). If it does, you swap stuff around. If you guessed correctly (and it appears you did), pat yourself on the back and let the thread descend into the usual sort of madness.
Because delving into inner workings is a minefield whereupon you often end up with wrong answers to wrong questions, and your house burns down because of, for instance, standby transient overshoot (or at least that is what you end up believing).

@izzion there's this electric/electronic/techical Polish forum called elektroda.pl. It's known for its extremely strict moderation - something even Jeff never dreamed of. There's a few memes about that site going around in IT circles, the most common being that whenever you make a help topic about anything related to computers whatsoever, if your PSU happens to be one of the brands on their community-maintained blacklist of bad PSU brands, your topic is closed by a mod within five minutes because your problem is definitely caused by bad PSU.

@Gąska Typically processor, GPU will state their power draw in Watts. Hardrives / CDRom drives after that are the biggest power draw.
There are calculators out there which will give you a rough estimate.
-
I usually just shoot for a good brand in the 400 - 500 watt range. Unless you're overclocking and running multiple GPUs, 500 watts is overkill these days.
Although I finally switched to a laptop, so it's a moot point, but it's more powerful than my old desktop, does 4k gaming, and runs under 200 watts.
-
@mott555 I used to have a 450watt on a AMD Athlon XP rig with the legendary 9700Pro. I have a 750 watt which is overkill, but the price between that and the 500-600watt PSU was about £15 so I decided to just get the better PSU.

@sweaty_gammon
To some extent, "overkill" is what you want to shoot for, if comparing to average base load. My understanding is that PSUs are most efficient at about 30% of their rated maximum, so if "normal operation" power draw for your computer is 150W, then you should target a 450W power supply for it, give or take.So I usually just look at the wattage draw of my graphics card, multiply by 4 and by 5, and look for a power supply in that range.
-
@izzion I think back in 2012-2014 there were some crazy cards being released. I am being slighly hyperbolic but I remember some crazy cards being released with two GPUs on a board and the card was like 2 foot long and could barely fit into regular sized ATX case. So when I was buying the PSU I did have in the back of my mind those crazy GPUs and their power draw.
-
@sweaty_gammon My decommissioned desktop has a 1000-watt PSU in it. I have no idea why I got that because that's a few levels beyond overkill.

probably run a mining rig on a bit of kit like that.

@sweaty_gammon dual core GPUs are still being made. Don't know about their sizes, though.

Okay, maybe it was leftover from an old mining rig. I did a little bit of Bitcoin mining back when the stuff was worthless (and I sold it all while it was worthless, too
)

No these were dual GPU. So two GPUs on one board. I think this was a little later than the time period I was mentioning but close enough to what I am referring to.

)I was mining it back in 2014 on an old rig with some AMD cards. I had like 200-300 bitcoin and sold them off for like £3000-£4000. It wasn't a bad investment at the time. If I kept them I would have had like 2-5 million.

Dual GeForce GTX 760 GPUs provide 14% faster game performance
Sounds like money flushed down the toilet. I mean, two GTX760s in regular SLI will give you a bigger performance boost.
-
@Gąska I am sure it is. At the time though there were quite a few cards coming out like this and it looked like the direction the industry would be going.
-
@sweaty_gammon and indeed, 14% faster game performance for twice the money is exactly how the industry went.

I can understand why they wouldn't touch certain brands if this is the quality of components you get:
Closed:
Opened up:
I don't understand moon language, but was this fake component supposed to be a transformer? The way it's built it can't even serve as a ferrite choke.

Reading the translated page, that's exactly what it's meant to be: a "choke" out of a "Take Me" (Out?) power supply.
Seems to me that the snobs have a point.

That's not the most common cause though. The most common is 'This issue was already discussed a thousand times, use the search feature. Topic closed'. Then you try use the search and only get a thousand other topics, all closed for the same reason.

Yep, fake EMC choke. That's an impressive level of fakery though. The usual trick is that your sample units come with all the EMC components fitted and then (as they don't affect the general operation of the product) they're mysteriously missing for the production batch. Had suppliers do that more than once, including a domestic one where they claimed it was a BOM error....we believe you
Someone did a YouTube video where they found some solar garden lights had fake solar panels that looked real but actually ran, briefly, off an internal primary cell. At that point why not just make the bloody product be real.
