Hey Guys! I am building a new PC very soon and need a helping hand choosing a 500w PSU. It must be under £45 as I am on a budget and must also provide 2 PCIe Connectors in order to power my GTX660 linked below. I don't mind if the PSU is modular or not although of course it would be nice to have a modular one so I don't get lost in the world of cables! Thanks.
