What power supply in stock can run 5 280xs?!

I was looking at the 1600w Hercules thats the only available powersupply with high enough watts i can find, but everyone telling my the quality is bad.. i also seen on reddit someone using it to power on 6 280xs and hes doing it successfully.
so if i only do 5 will it work for a long time?

seeing as i wont be getting lepas because theyre sold out everywhere...

any help please

For our 5x 280x rigs, here are our power numbers:

At stock volts (1.13), our rig pulled ~1450W.
After undervolting (1.01), we pulled ~1250W.

You don't need a 1600W. You can get away with a 1500W. We use 2x 750W Rosewill Capstone, and they work wonderfully.

Two smaller PSUs are usually cheaper than one large one; We got our two for $100/each.
