1080 msi seahawk hybrid and sorry i meant customer services.
more or less got told its not a fault and doesnt affect performance there isnt a lot i can go as for upgrading the power supply i already own a Corsair HX1000i. i cant really be spending more than i already did for that.
That PSU should be fine, and I bet there have been a fair few people buying new PSUs only to find that it doesn't cure the coil whine.
BTW I think CS? means which retailer's customer services ? You can't mention competitors, but you can say if it was bought from Overclockers.
