Good modular power supply

[Rofster]

So I'm upgrading my old computer so I could play games with it. It's Asus k30ad. I'm going to get i5 4460 and r9 380 and if I'm right I should be good with 600w+ psu(?). My problem is that the psu I have right now is 140 x 86 x (130?)mm. I would like to get a modular psu so my cable management would be easier with this kind of case. I thought seasonic 620w m12ii would have been a good psu for me but it is 160 x 86 x 150 so it would probably be too big for my case. So i need help to find a modular psu that is not too big for my case and hopefully less than 100€.
