Hi
I need help with this PSU: http://www.ebay.co.uk/itm/0JX399-Dell-PowerEdge-2950-750W-Hot-Plug-Redundant-AC-Power-Supply-Unit-Z750P-00-/281038936437?pt=UK_Computing_PowerSupplies_EH&hash=item416f39d975

Can anyone help me with choice of this or any other one which will fit s1.
I had corsair cx500 but price is to high.
