ok so i just ordered the card mentioned in the title after noticing the 750 ti offered the most power for low wattage psu's however after ordering it ive noticed some inconsistencies in published system requirements for this particular card vs the regular 750 ti some sites say 300 watts some say 400 watts. my desktop is an asus i bought at best buy with an a10-6700 8 gb of ram and windows 8.1 300 watt psu, my question is will the pny oc edition be ok for this or do i need to return it and settle on the normal 750 ti, is there a program i can download to determine if i have the spare wattage in my current set up, the a10 apu i read is supposed to be relatively low power and would the cpu not use less power if the integrated graphics are not being used anymore with the dedicated card being added? thanks for any advice
