Have the AC adapter I bought from Ebay (ca 3 years before). Since my computer works perfectly: MB: GIGABYTE LGA 775 CPU Dual Core I3 VIDEO: NVIDIA GTX 470 (only the card 150W). Often played games RAM: 16 GB HDD: 2x1TB RAID DVD Writer
To date, no problem.
PS: Positives: The part is a Active PFC (not passive!) Built -> Storm consumption goes down!
