Hi, guys. I live in Singapore. I bought an Aurora R7 (850W PSU) from Amazon US. I knew this PC is intended for use in US where household voltage is 120V but the spec sheet says it works in 110-240V range. I wonder does it work in 220V environment. I heard clicking sound from PSU every time I switch on my PC or wake it up from sleep. Is it abnormal? Does it have any switch to adjust voltage or is its voltage auto-adjustable?
The PSU part number is 31T69 with description : LABEL, REGULATORY, 850W, ENVIRONMENTAL PROTECTION AGENCY, JSD2, R7
Thanks for any help.
