I have a Corsair AX760 Watt PSU which is still new in the box but is an older model. So it was never used. It was meant to be build in a high end gaming PC but that never happened. I see that this one is still available in some shops but I wonder how the price relates to the quality after three years.
Which new generation power supply will be a mentionable replacement? Like the old model it is for a high end gaming PC too but should meet the requirements/standards for a modern gaming PC (see below). If new models have some benefits over this older one, what are those benefits and is it worth it spending the extra money while I have this unused PSU?
Some background: I expect to build a new PC somewhere in October just for gaming, including Core i5 or i7, gaming motherboard, DDR4 memory, higher end graphics card and SSD (that's all it will contain). Everything I don't have to buy can be spend on the GPU hence my question. A complementary question: The old model was intended to power two graphics cards, I'm not sure if I'm going that route this time but if I do would that influence the answer? Take into account SLI and Crossfire as I've not made any decision yet what to buy.
