Question Where is problem in my configuration ?

[Iso2002]

My configuration is :
gpu : rx 480 4gb sapphire nitro
cpu : amd fx 8350
motherboard : msi 760gm-p23(fx) (ms-7641)
ram : 12gb ddr 3
psu : 500w lc power LC500H-12 V2.2
but i have problem with fps , recently i bought rx 480 4gb , previously i had r7 240 , and ofc i expected to get better fps but dont know why fps is same , maybe even worse . I think problem is in psu because it have only 1x 6 pin but rx 480 requires 8pin , so want to ask what u think if i buy new psu will my fps improve , because my motherboard have pcie 2.0 maybe this could be a problem .

cpu/gpu temp and usage during the game?
could be the low end psu.

 

[drivinfast247]

The motherboard can't support that CPU and that PSU isn't helping the situation.

Did you say that you aren't using the correct power plug for the GPU? You can't do that!

You just need to build a new PC. That thing isn't worth spending money on.

MB in first place, funny RAM configuration and PSU for sure because of GPU. All together, as much of mismatch of components as I could think of.
