XfX pro750m or Corsair Profesional Series AX750. I kinda think that AX is better but it costs much more. But does these two have a BIG difference? Or I can take the xfx and wont regret that? Need some opinion, thanks.
Neither Corsair nor XFX make their own power supplies. Both PSUs listed are outsourced to Seasonic to make them. Seasonic is arguably the most reputable and reliable PSU OEM and is perhaps the best PSU OEM as of today. So pick whichever is cheaper. Both are excellent power supplies.
