I wonder if there is anyone smart out there that has invented some sort of adapter to power multiple PCs with one power supply,
in that case a 1000W would be useful

Great deal! I paid about the same for my RM650x a few years ago.

https://www.corsair.com/corsairmedia/sy ... -table.pdf for spec table - this unit is on page 3.

Efficiency at 115V:

10% load (100W) - 86.33%
20% load (200W) - 90.39%
50% load (500W) - 91.13%
100% load (1000W) - 87.94%

I'm actually shocked how efficient it is throughout the power band!

For comparison, here is the same charge for the RM650x... you don't lose much efficiency with the 1000W model:
10% load (65W) - 90.58%
20% load (130W) - 92.76%
50% load (325W) - 92.16%
100% load (650W) - 87.66%

You mean like this device?

Phanteks even makes the Evolv X case that supports dual systems in a single case.
Some people just don't get that online forum posts shouldn't always be taken seriously.

My Xeon, watercooler, 390X and the dozen fans needed to keep it from catching fire run up to 650w under load. I use a 950w PS but 1000 isn't overkill like some people are saying.

Unless ur doing benchmark test 99% people are not running max load 99% out of time. That being said, when ur browsing internet, watch video, using word excel, ur using 10-20% Max load; gaming, probably 50-80%. I have 8700K water cooled + 1080Ti, 70% my time is just idle or browsing internet about 120w, and rest 20% gaming time only 250w ish, video editing rendering is about 300w.

Probably this PSU is for those top 1% user or miner(which is currently dead).

In my opinion, long sustained loads include gaming. You would want a good reliable PSU when you are using your PC to its capabilities. Would you want a PSU run to 90-100% loads for hours at a time, or a PSU running to, let's say, about 60% loads for hours at a time?

600w seems like plenty for the average guy and 700w to 750w for the guys overclocking or throwing in a bunch of hard drives seems reasonable. Thoughts?
In addition to all the great comments above, capacitors also degrade over time. 1000w means you can use the PSU for a long, long time.

This is pretty much as close to buy it for life as you can get for computer components. I can see it lasting more than a decade easily.

Yes, they've done it. It's called buying a second power ribbon to attach to this modular power supply . Each computers just need power, they wouldn't need a special adapter.

I have EVGA T2 and paid more than double this price...not worth it.

Never has there ever been a chasm wider than the one between those that say you should a psu that provides at least twice as much power than you need, and those that say you should get one that is as close to how much power you actually need...

Just had coil whine with my last PSU after I bought a new GPU. I've tested around and it narrows to the psu. My old pc's psu which is 750w has negligible whine. I then tried underclocking my GPU with my 550w, whine goes down more i underclock it.

Conclusion: get more watts. Contacting the manufacturer said the same thing. Though I was annoyed because I used their bloody calculator to determine my PSU and they wouldn't RMA because whine isn't considered a manufacturer defect.
