What are the chances of getting 3 different psu's DOA

[Dominicanfrieza]

2 750 watts and an 850 watt havent powered my system at all but my old 500 watt psu does fine?

Extremely unlikely. 

Would help to know what your system is, what the 3 power supplies are that didn't work, what exactly happens when you try to use them, and what the power supply that does work is.

Are you sure everything was plugged in properly?

That the power switch at the back of the PSUs was turned ON ? 

That it actually was plugged in the wall (easy thing to forget) ?

 

Because 3 DOA is highly unlikely.

Mixing a CPU and PCI power cable maybe?  This would keep a system from booting.

Hmm I'd say the chance is about 0.00000001%.

No, there's something wrong, and you need to find the problem.
