More about 400w bottlenecking
  1. It's definitely not good to run an ElCheapo POS PSU, but it will not cause any bottlenecking. The causes for bottlenecking can be traced to 2 things: CPU, and GFX card (what res are you playing at?).

    Dynex is not a good PSU. Look for: Enermax/Lepa, Silverstone/Seasonic, Antec, Corsair, XFX, newer OCZ units, and PC P&C.

    I'd look first to upgrade that vid card (even a 550Ti would be an improvement for $125), after getting a better PSU (look for a 450W-550W).
  2. Most defiantly get a better PSU. That is a Best Buy only cheapy with a very low efficiency especially under load. Your system will pull 300-350w so a good quality 450-550w PSU would do fine and give you plenty of headroom.

    Absolutely a poor PSU can take the rest of the computer with it. Ontop of the poor efficiency your 12+ rails are on the low side (14a and 15a) so just upgrading your GPU could send you over the amps it can provide.
