Can I run with this PSU?

My first build ever.

Specs.
ASUS M5A78L-M LX PLUS AM3+ AMD 760G Micro ATX AMD Motherboard
Phenom II X4 965 Black Edition
ASUS GT 440 1GB GDDR5 128-bit
G.SKILL Ripjaws Series 4GB 240-Pin DDR3 RAM
2 DVD Write/Burn Combo (can use 1 if needed) (They are from OLD hp I have)

Case:
Rosewill REDBONE Black SECC Steel ATX Mid Tower Computer Case

My PSU:
Can I run on a 300 watt PSU that my REALLY OLD HP has because I can't afford a PSU since I'm not old enough to work?
I can't afford buying a PSU so please tell me even if its running on a 80-95% load.

I also won't be overclocking anything, just if you need to know that.

  1. It's still not a great idea, but it's better than what your original post was planning; how old is the PSU (in years), and how many amps is the 12v supply rated at?
  2. Best answer
    Max power draw of the GT 440 is 65W and Nvidia recommends a 300W PSU..it is definitely worth a try with your old PSU and I'm willing to be that you'll be good to go.

    THANKS A LOT. I really needed this and I would be good to go to build the system since I wasn't sure. Of couse in 2 months or so later I will probably buy a 400 watt power supply but this is what I needed to know. Thanks
