Random PC Shut off - thoughts?
Recently purchased some new parts...
EVGA 680i LT SLI 775
Intel Core 2 Duo E6750 2.66 Ghz
Corsair XMS2 2GB (2 x 1GB) 240 pin DDR2 800
160 GB Western Digital SATA
To go along with my previously purchased parts
2 EVGA 7900 GT KO
1 Rosewill 550w power supply
Since putting all these together I have experience complete shut downs...
Wondering if I simply no longer have the power to supply all these parts?? or any other thoughts? Have checked all connections, no dust or over heating... just shuts off. Do I need to purchased a larger power supply to meet the damands of SLI for RAM and GPUs?
