So, what power supply should be used for these items to get maximum efficiency and reliability? Money no object, especially during these 'Covid-19' rip-off, wallet gaping times.
Quite late, sorry m8.

For the best efficiency and reliability at that wattage rating and money being no object, I would most definitely pick the Seasonic PRIME TX-650(or Prime 650 Titanium, they're basically the same). Kind of the only choice really.

Just bought the Cooler Master 550W bronze. Don't have too many choices nowadays and the price was good. Only worry I have is that the motherboard that I will be using comes with 1x8pin cpu and 1x4pin, power supply only comes with 1x8pin. Will this be an issue?

Not unless you're heavily overclocking a top op the range processor(10900k or 3950X for example), you only need to plug in the 8 pin for normal operation.

You won't be close to maxing out a single 8pin even with a heavily OCd 3950X. :)

It draws about 265W through the 8pin EPS cable at 1.35 volt, which exceeds the 235W continues power rating. While its probably not enough to cause damage or instability with a decent motherboard/power supply, it isn't within spec.

If you're going to correct someone, you might want to be sure you have your facts right... :)

Don't know where you got that number from but the 8 pin is rated up to ~600W depending on the power supply. Simple math, really. 4 12V wires x 7-13A = 336W - 624W.

Thanks guys! What about quality of the PSU. Its pretty damn old but for $60, I thought it was worth it.

Its a decent enough unit for $60, at that price point for a 500-600W psu, you're not going to find much better these days.
That's what I figured so I just went with it.

I need me a as cheap as possible PSU for a simple office rig and I am totally not familiar with low power PSU's and quality of those.

What would you guys recommend for a i5 4670, 2x4GB DDR3, no GPU, a single 64/128GB SATA SSD and a simple case with a single 120mm fan and a cheap-o CPU cooler or stock cooler if I can find one lol.

Or should I just get a secondhand old M12II 520w or a Earthwatts EA600 or something as you see those float around for like 20 bucks here and there.

The Seasonic S12III is the cheapest thing i would recommend even for an office machine

Has anyone gotten a really high quality 10 year warranty SFX Power Supply in 2021?

Interested knowing whom are making decent SFX PSUs worthy of buying, because the current range of models don't exactly excite me with confidence or trust here :( .
