Titan
Ambassador
Need power supply details.

A GT210 will be running off the motherboard, but it is still quite low power. A 60W GTX750 or 70W+ GTX750Ti could be pushing it a for a 250W power supply.

I'm trying to think of a core i7 with a 2.66Ghz clock, and I am only coming up with first gen, so this might actually be a higher power system. The actual model of the processor and motherboard would be helpful to know.
