Well since it's still doing it's job, it seems you lost the bet. It's doing everything I expected of it. If I had needed a hard core gaming machine I would've bought one.Yes. Have you tried running Crysis for 6 hrs @ 1080p? Any upgrades you add may overload that PSU, and its a mystery what the rails are rated at, or the ripple figures or the efficiency curve or well anything. And the motherboard - ?
Nevertheless, thank you for your sincere concern.
