you can find french retailer in france from evga their website I think.
Personnally I wouldn't buy a cooler master (I had problem with one) go for corsair, seasonic and other reputable brand (wouldn't go for evga either because they are probably more expensive and you buy mostly the brand... probably the case with corsair too tbh and they probably just rebrand seasonic psu

)
yeah actually go for seasonic, they are building their psu...
I have two Corsair 550W gold that are perfect for 750Ti rigs. But given the 970 prices in France, my next cards are going to need more oomf...
I found a Seasonic 1250W gold for 255 on the same website. It should be fine if I mix the cards. Something like 4 970 + 2 750Ti per rig should do the trick...
