my current build is a
Intel Core i5 750 (lga 1156)
asus P7H55-M
8gb ddr3 ram
2 hard drives 250gb and a 160gb
2 dual layer burners
Zalman CNPS5X Performa CPU Cooler
2gb asus GeForce GT 610 video card
creative 5.1 sound card (really old one pci, i don't even know why i still have this works perfectly though)


my question is my mother board is an 8 pin but it is working with a 4pin, and im running this current build with a 300 watt power supply, i am going to get a new power supply this week, just cause " i can" but i want to know am i really going to see any difference? cause right now i have no problems at all no blue screens, no random shut offs every thing works fine, if i do get this new power supply will i see any difference? my computer even runs quiet...
