Everyone will need to buy a new Haswell motherboard. Unless the reports I've read months ago changed, Haswell is going to be on a new socket.
Correct. Haswell is LGA 1150, SB/IB were LGA 1155.

Not likely. The problem is that the PSU will shut down (self protection) if it has less that its minimum current draw. It has to do this because the voltage regulation loop goes unstable if it was designed to have a higher minimum current draw. If the PSU didn't shut down, it would fry things, including itself. Really bad. To test the PSU works at 0.5A would end up shutting down the computer if the PSU didn't work at…
Ah, yes, the other side of the Halting Problem: not only can you not tell if your program will ever halt, but you also can't tell if your program has been externally halted.

WTF is up with this? Is Intel just taking as much money as they can? Or are these legitimate issues that they waited to address?
Couldn't Haswell motherboards automatically test the PSU on bootup?

I consider it borderline negligent to use anything other than ECC RAM in any machine where you care about not corrupting your data with a flipped DRAM bit.
Except it's virtually impossible to find a CPU that supports ECC. I've used ECC in every one of my machines for the last decade or so - except for the very last once since it's was impossible to get without spending a crazy amount of money (xeon processor).

On the contrary to your contrary: the kind of person who builds their PC is the kind who customizes how it works when they're using it . There's no automatic assumption that they also harbor green feelings and want lower power consumption for idle/sleep. Hell, many are proud of their beefy 1kW+ power supplies and the ridiculous power load they draw. Others are proud of their energy-destroying bit-coin mining setups.…
Anecdata, but my current build has been stalled on the availability of the i7-3770T (the 45W TDP part). I'm already using LV-DIMMs and SSDs. My actual, active goal is to build a quad core machine with 16 gibibytes of RAM that can draw IOW, you can't assume that those of us who build our machines are all, "Look how big my electric bill is!" wastrels, either.
TDP is all about cooling capacity and PSU capabilities. If you're worried about saving energy, get the processor that will run at the highest speed while computing so that it can get back into power-saving mode sooner. And you can always under-clock the standard desktop CPUs if you really want to - a 3770 can be configured to behave pretty much like a 3770T by tweaking the base and Turbo multipliers.

It's not virtually impossible. It may be virtually impossible in crappy cheap boards from Taiwan, but if you're buying cheap parts then you're likely not making money off the results that you're producing.
It's not the board that is the problem, it's the CPU. Only xeon CPUs have ECC support, and they are just too expensive.
And as mentioned elsewhere, AMD's consumer CPUs support ECC if the motherboard enables it.

They're really not: http://pcpartpicker.com/parts/cpu/#k=14&f=29&c=4&... And as mentioned elsewhere, AMD's consumer CPUs support ECC if the motherboard enables it.

Looks like the xeon is about $50 more than the equivalent i5/7. It was worse before, when I bought my most recent motherboard.
