Hum Tom mate I would stick with the HX 650 or go the 750 - I have the 650 in my Sandy Bridge (Coolermaster Centurion II) and it is a real nice PSU and if possible the case if you can go the HAF XM is going to knock spots off the 890 for space and the number of fans that that you can fit mine has 1 x200mm front 2x 200mm top and 2 x 140 mm - side and 1 x 140 mm back and just makes t so quiet to operate. But it is your budget mate but from past experience I always wished afterwards I had gone the extra mile with the gear (especially the case) when building the Sandy.
