Hi I'am new to pc building.And my parts are:
Gigabyte f2a68-ds2 MoBo
A10 7870K
2 4gb ddr3 Hyper x
Wd 1tb hdd
18.5 asus monitor
Normal mouse and keyboard

I dont have graphics card
The problem is I dont know what power supply should I use, they say 500w is an overkill to this build. The pc shop were I went wants me to go for a 230w bysuo (a chinese brand) power supply and I dont want to because that power supply looks pretty lame even though they say its "true rated" other shops only have 450-500w they dont have a 230w psu. What should I do? Is there any other options? PS. I dont really want to add a graphics card because thats what they said that if I want to go for a 500w I should have a graphicd card hope you guys can help me out :)
