Brand upgrade 4850 graphics card, how to match the power supply?

The power of the graphics card is only 50W higher from 3650 to 4850. It doesn't necessarily mean that your original power supply can't be used ~ Do you know how much your original power supply is?

Supplementary answer: I just checked the 300W power supply of 530 from the internet ~ your configuration is enough ... there is no need to replace it for the time being. ...

Continue to supplement the answer:

First output: 350W means rated 350W. Let's calculate the power: Q8200 70W fully loaded with 90w HD 4850110W+050w fully loaded 150W motherboard 25W optical drive 25W hard disk10w memory 2.5W*2 plus mouse, keyboard and fan. 350W power supply is enough .. Not a brand machine, Q ..

I believe you spent a lot of money on this brand of computer ... save a little. There is really no need to invest any more.
