I just bought a 2nd Nvidia GTX660 to run in SLi mode. It runs fine until i start up a game, i.e. BF3. I heard a weird sizzling sound coming from my computer, at first i thought it was the new gfx card, but when i put my ear up to the PSU i could tell it was coming from there. Now im wondering if my PSU is able to support my 2nd GPU.
Specs:
Intel core i7 3770k (not overclocked)
Gigabyte Z77X-UD5H (mobo)
16GB(4x4GB) Corsair Vengeance
2xNvidia GTX660 in SLi
700W power supply
3 HHD (1TB, 640GB, 250GB)
1 SSD (128GB)
CD drive
3x220mm case fans, 3x140mm case fans.
Should i get a higher wattage PSU? or just replace current 700w with another comparable new one? My current PSU is probably 2-3 years old, and all the components except for the HDDs are newly bought.
