They are wrong. Shitty PSU's are inefficient and require stupid amounts of wattage to supply parts properly. More than that what matters most is the rail voltage: which is what your GPU needs, for example. Poorly made PSU's don't have ample voltage hindering your parts, so people wind up buying 750W $60 PSU's thinking they are the shit because the numbers are higher.
No single card setup requires anything above 500W, no matter what you throw in there barring an insane number of components like 6 HDD's and 3 Blu Ray players. You are always better off getting a rock solid, lower wattage PSU as its more efficient and does a better job of giving the important parts the voltages they need.
This is why you can get a 750W PSU for 60 bucks, and a 520W PSU for $120. One is inefficient and cheap, the other is super efficient and rock solid. Theres a happy medium there too, but good PSU's are usually in the 60-100 dollar range for a single GPU setup, barring any special deals or manufacturers being super competitive.
If a PSU is offering 800W for the same price Corsair is offering 450W, something is wrong there.

I've taken everything out of the motherboard and removed the board from the case to rule out a short, but the power supply still cuts out a second after I hit the power button.
It spins right up and runs fine using the paperclip trick, so maybe its only dying when it actually has to pump some power out?
Anything obvious I'm missing? I'm probably RMAing this one and grabbing something locally tomorrow, otherwise.
If a PSU can't give components the power they need it shuts down. This could mean you have a bad PSU or it doesn't have enough power. Otherwise its just dying randomly and is faulty. Either way you should return it if nothing else is obviously causing the shutdowns.
If you are going local you really can't go wrong with anything by Corsair. Everything they make is pretty much perfect. They aren't the only good PSU's but by brand alone they've earned a lot of good will from PC builders for being reliable.
