Do I need to buy a better power supply for this setup?!!

[plotgee]

Hi friends!
This has been causing me a whole lotta stress and confusion considering the wide selection of computer hardware.

I have a stock 380W power supply. I am wondering if it will support what i plan to install or will i have to buy a more powerful supply?

my specs next week will be,

MOBO: M4A78LT-M
PROCESSOR: AMD Phenom II x2 565 80w
RAM: DDR3 2 Sticks 2x2GB
GRAPHICS CARD: Asus radeon HD 5450
HARD DRIVE: SATA 1 TB
DISK DRIVE: DVD+R DL
FRONT BAY CARD READER
And 4 cooling fans not including heatsink.

Will my 380w power all this? I also plan to over clock my phenom.

Please i already tried the power supply calculator and they all tell me something different, so any of your opinions will be highly appreciated thank you!!

Well the 5450 needs 400w or greater.

First we need to know WHICH 380watt power supply. Some are good some are crap.

Ideally you'd want more than that.

Rick is right in asking what specific brand PSU you're using, but I think even with an Antec or Corsair (top quality) PSU, you'd be pushing it.

Good luck
