Hi there I'll try to best be brief with this issue as it has been recurring and as a result a bit bothersome lately.
I originally made my current build with one of your 650w G2 80+ Gold PSUs, and had absolutely 0 complaints up until near 18 months of service in which a bothersome "squeak" sound begun to originate, getting worse with time. I RMA'd to the Lancashire center in UK and was sent a replacement via Germany (Given a 650w  back, thank you for that ).
 
 However, fast forward 10 months service under the same load and frequency and this 650w replacement I was given as a result of RMA has now begun to produce the same "squeak" noise as before. Whether it is a faulty capacitor or the fan bearing I cannot be certain, but with a 7 year warranty on this unit in UK I obviously wouldn't wish to void it just to find out by myself. My only issue is that to have been given a PSU that is a level up and have it display the same 'fault' in a significantly shorter time-span just puts me in a loop of having to RMA once a year until I for whatever reason purchase another PSU altogether, leaving me without a PC for a week or two in the process . How should I go about rectifying this issue a second time with you guys?
 
Many thanks.

Ask evga for a prepaid label. 

Would this be through the usual ticket procedure?

I'll give them a ring then, thanks.
