GPU Upgrade need new PSU

[Hi Im Mig]

I want to upgrade my graphic card but my psu only has 6pin PCI-E and i need 1x8pin i want to know a decent one but not to much expensive.

550W PSU

the best budget 550W range psu's IMHO are the seasonic S12II/M12II or the corsair cx550 in gray and black (not the green run from the green cx500)

Any one of these will do you just fine for a good long while
