I want to play light games like Team Fortress 2 and CS:GO, and I've been looking for a processor. After everything, I've looked for one that could work on a 220W psu, that's low-profile, and that's affordable. I found either the SAPPHIRE HD5450 or Asus 5450. I don't know which one to get, but first I need to know which, if either, will work better on a 220W psu.
Here are my calculations if interested:
~~~~~Computer Wattage-Gateway SX2851-09e~~~~~
Intel Pentium G6951 - ~73w
Intel H57 Express Chipset - ~5.2W
6 GBs DDR3 SDRAM - ~8W
SATA 3GB/s Hard Drive - 15W
Variable Spindle Speed - ?
Keyboard + Mouse - 2.5W
Current Graphics - 15W
Case Fan - 2W
Safety Zone - 20W

All together - ~138.7W
Power Supply - 220W
Safe Extra for Graphics Card - 79.3W
Hd 5450 - 19.1W
Extra - 60.2W
