2psu per 8 1080 ti rig
Evga 1000 g3 and some 1800 watt from aliexpress
The one from ali makes more noise,since it's fan have no speed control,but they both are good psus
Aren't you worried about the nonbrand 1800W PSU ? You can afford 1080ti and can't afford decent PSU ? Isn't it like buying nice sportscar and installing the oldest and ugliest rims and tyres ?
