if you're buying a non-modular PSU because you want a budget PSU then - a different brand. Seasonic doesn't have anything good enough to other than Focus/Prime.
If you're in US, there's a Bitfenix Formula Gold 750W for 65$. It's kinda ugly buy it's a good PSU for the price.
750W PSU for $65?Surely You're Joking, Mr. Feynman!
