Hello, hoping someone from scan will be able to help me. I recently spent over £1000 at scan on my new computer build. It appears that my power supply is faulty as it makes a horrible whiny noise when I play any game. I have got an rma for the power supply and it is being picked up on 17/8/11. However, if it's faulty I would really like to swap it for another power supply altogether and I would pay the difference. They seemed to indicate this would be not possible over the phone. Can someone help me, I'd appreciate it so much and continue my custom at scan if I could sort this issue out. Thanks.
