Man, listen. I have an
Asus GT 730-2GB-DDR5. I used it with a
Mercury third class crap PSU 450W and this psu has shoved a lot of headache to me, like black screen flash, flickering, slow boot, etc.
And this crap psu died after 6 months. Ya 6 months after purchase! I mean, it was 450w psu with 10% efficiency! What a crap!
So, I recommend you to buy a good psu like Corsair to run that GPU or
you can check this and select your favourite.
I'm going to buy a Corsair VS450 next month. Btw, Which is your psu?
i use http://www.coolermaster.com/power-supply-calculator/ to calculate the wattage i need to power my whole pc
and the result is :
load wattage : 124 W
recommended psu wattage 174 W
Man, I have:
Core 2 Duo E7500
2gb ddr3 (4gb will replace it)
G33 Mobo
Samsung 500gb hdd
GT 730 2gb ddr5
Still I will go for a good psu with 80% efficiency rather than my old Mercury crap. I never heard about any 230 watt psu. Corsair's entry level psu's in Asia is VS series and in West it's CX series. There is no 230w psu's of Corsair. VS350 is least priced psu of Corsair in Asia. Don't know about what's in West.
