Most compact 180-200w power supply available that works with clevo

I really need to find a better power supply solution. Slim/compact/small.

Only needs to power a gtx 970, 32gb ram, 1 tb ssd, and core i7 47xx or 48xx

Ive seen some really compact power supplies with asus and razer... why cant clevo have something similar.. id be perfectly happy to buy the Asus or razer 180w if the connector will either fit or be modified to fit clevo
