What's the maximum amps available on the +12 V rail?
I've been thinking about purchasing a GTX 750 Ti video card. It requires a minimum of 20 amps on a +12 V rail would this power supply be sufficient to run it?
It depends on the rest of the system. The Dynex 400w PSU, if you dissect it, is only rated for 250w continuous power. See this review:

If the rest of the system has anything more than basic components, then the answer might be no. Best Buy carries a Thermaltake 430w PSU that would be better, and is only $5 more:

Alternatively, you could go for the Corsair taht is only a little more and is a really great PSU in terms of quality:

It will also allow further upgrades down the line, and would easily go into your next system.
