Nope. This will be a HUGE mistake if done. One can source 10-20-50 PSUs, but how about a few thousand of PSUs?

We're out of stock on the SP35.

So next gen soon?
Use a built in psu that's common like the dps2000, and ship without them? let us buy our own, Big savings there

+1/ plus, having the users install the PSU makes troubleshooting more difficult since right now SP-T can verify that the SP3x units are shipping with a working PSU and act as inended. allowing users to dump used PSUs into the unit opens up a big margin for error

also, the DPS2000 would be tough, since its airflow goes ACROSS the PSU, rather than down its legth like the current artesyn/emerson/murata PSU style.

anyways, the PSUs SP-T is using are basically common-slot already. This is visible from the fact that they have multiple power ratings and brand names to choose from when assembling and shipping the SP3x series

max is 288watt/ 6pin connector

official recommendation 16awg, 40cm long

personally i would go with a bit thicker, like 15 or 14awg

The voltage and draw on the SP20, is 3280ish watts per plug or per pin?

Trying to see what 14awg wire will handle

14 awg will handle more than the pins or connectors Housing them.

Lets make things interesting by calculating an average of 3-4% diff jumps every 13 days @ .11 kw/hr. Mined btc drops by 40% in 90 days.

those diff jumps will grind to a halt quickly though. unless the price pushes past $250 its unlikely difficulty will exceed 55B until the next generation of hardware is available.

once spring comes and things warm u, a lot of home miners have to sell or turn off gear to keep cool and save money when summer electricity rates begin

Its not just home miners, big farms and their speeds are impacted by the heat as well.

Remember not all miners are in the northern hemisphere. It's slowly warming up on the top side of the planet, but the bottom side is slowly cooling down.

While that's true, I'd be really surprised if there was much large scale mining going on in the southern hemisphere. Power prices in Australia are outrageous, as well as most of South America. I don't know how power pricing runs in Africa generally.

You do realize that half of the world is in the southern hemisphere. How do you come about your assumptions? Roll Eyes

Because I've built datacenters in Australia, Brazil and Argentina as well as in Europe and the US? Dealing with electricity costs and stability in the southern hemisphere in my experiences have been far more difficult than in the North. Electricity costs for industrial electricity are above $.11 USD in most of South America whereas in China and the US you can find electricity for about $.015 USD for industrial in certain areas. Something else to consider is almost 90% of the world's population lives in the Northern hemisphere.

... I think he is meaning population...

Overwhelmingly, the Northern Hemisphere has the greater population.

Northern Hemisphere: 88-90% of the population
Southern Hemisphere: 10-12% of the population

Greater landmass as well, 68% of land is in the Northern Hemisphere.

Maybe, but the option could be given. I for one own a number of power supplies, so paying $800 more for the sp30 to get new PSU, and the extra shipping weight?
Be a nice savings point
