I am reeving some part which are an i5 3570k asus p8277-vlx and an r9 290x with 8gb ddr3 ram. I am building this as a stop gap and need to buy a PSU but don't want to spend too much, I am considering upgrading somewhere down the line but I would need to change everything to new gen. Which of these parts should I buy?PSU- ATNG ATM-550FB 550W Power Supply 80 Plus Bronze or Aerocool Cylon 500W 80 Plus Certified Power and for the case AvP Opius Gaming Case - Black or CiT Venom Mesh Gaming Case with Black Interior and 12cm Blue LED Fan. Any other suggestions as well, ideally adding up to £60 max. Thank you
