Hi all

I am looking for a new graphic card, to get nice frame rate, for gaming. Do not want to spend too much. But I also do not want to buy a new PSU to use it. Build is:

  • * Intel Core i7-4790
    * Kingston ValueRam KVR16N11/4, 4GB, DDR3-1600
    * ASRock H87M
    * Corsair VS450
    * Seagate Barracuda ST1000DM003, 1TB/1000GB
    * LG GH24NS95, 24x SATA
I looked at the Gigabyte GeForce GT 740 (GV-N740D5OC-2GI), and I see on the website it said it need 400W.
http://www.gigabyte.com/products/product-page.aspx?pid=5093#ov

According to PC Part Picker (http://pcpartpicker.com/) my system with this graphic card only needs an estimated of 233W.

Therefore, my PSU should be fine, and I do not need to upgrade my it. So the Question is when I look at these graphic card's website, why do they lie me? And how can one know what the True Power Consumption of a graphic card requires?

Thank bccorrupt, this cart can help me in my search. And thanks for the recommendation. But you think the manufacture's website would have Power Consumption details.
 


The manufacturers can only estimate because they don't know the rest of the parts you are using or the quality of the power supply you pick. Pcpartpicker or another online power supply calculator will work better.
