Done.
Although some hard choices in there.
I didn't actually put 'previous experience' as part of why i would buy another PSU, but if there was a fourth choice, I would look at what Corsair was offering first, as I've found mine to be fantastic. Cool and quiet, with never having a random crash even though overclocked. Only reasons for me to upgrade at the moment are lack of connectors if I went to dual graphics cards that requried 2 pci-e connectors each, or if I intended a mega overclock with a heavily overclocked high-end graphics card.
BTW... Am I still able to get the 8 pin PCI-E connectors for my HX520W?
