1000w is pretty overkill for most builds, i would suggest getting a good 500w psu instead

I dont see enough posts after 2 mins of scrolling to call that "lots of faulty 2080Ti", but this is old news. Either they have bad GDDR6 that quickly started to cause artifacting (hence does not affect 16 series with GDDR5) or a bad BIOS flash leads to GPU cores locking to their base clocks and not boost higher. This is a thing at launch, seems to have gone away after a month though and its now as rare as it was before with older cards. Super series does not seem affected either

Keep in mind that a manufacturer's forums are not an accurate representation of a product's reliability. People are going to go there first to say if something is wrong, they dont go there to say they don't have any issues.
 
Same can be seen on every single community forum for a particular company.

At one time, multi-gpu had noticeable benefits and 300-400 watt gpu were a thing.  Back then it wasn't that hard to need 1000 watts.  Now you would need to be building a very special purpose rig to hit that.  Many accelerator(gpu/compute/fpga/ect) cards and or cpu would do it.  Anyone buying i9-9900k and dual 2080 ti for example, or folding at home rig with quad gpu, would need around that wattage.  Single gpu and gpu won't, without hard mods and LN2 at least.

1. Render machines with multiple GPUs
2. Those aiming for best efficiency (on top of the highest 80+ rating)
3. HEDT platform users ($200 a PSU doesnt differ to them as a $100 one) along with multiple GPUs
4. Extreme overclockers (tho they usually aim for more, just in case there's a multiGPU competition going on)

I agree with this
