Hi,recently I bought a Gigabyte GTX 660 2GB GPU.When I mounted I found that my 400W PSU was not enough,so when I played more graphicly-intense games my computer just shutted down.So it was 10-14 times it did.But after the 10th time the comp started making a very strange noise(rattling).So I changed my PSU to Fortron 650W(very nice) and the rattling persisted.Is the GPU rattling?Or the PSU?Today I used EVGA Precision X to set GPU fans to 100 % precent and heard verry little rattle when the GPU got 100% and then it stopped-fans worked nomally.Interersting is when I play games-BF4,Watch Dogs the rattling is huge and the fan is again 100%(setted to auto from Precision X).The GPu temp idle is 35 degrees and 65-70 under load.
System specs:
Intel Core i3-3320 3.3 Ghz
Asrock H61M-DGS
Gigabyte GTX 660 2GB
8GB RAM
Fortron 650 W PSU
2TB HDD
Otherwise all games run lag-free but rattling is there.
