[MENTION=38670]mazkraven[/MENTION] If XFX is manufactured by Seasonic then for sure u should buy it
though u dont have a very power hungry setup meaning any decent 500W-600W PSU will suffice

7870 XT REQUIRES A 265W ie 22 AMP LEFT OVER BY MB/ACCESORIES on a single rail supply..PSU's which have over 50AMP ON A single rail can run this card easily,
PSU's having multiple rails ie epsilon 600W or 900W they have pcie1 and pcie3 on different rails means 18AMP on 12v1 and 18 on 12v2 or 12v3 can power this card too..
we prefer supplies that have multiple rails to overcome the load of GPU's and MB/ACCESORIES

Incorrect

265W is the combined System Wattage
Refer to the link posted by Generall for only GPU Wattage

Do note that Maximum Load is under stress tests like Furmark

Under heavy gaming these cards wont even come close to Maximum

7870Xt joker requires 210 under minimum wattage and 265 or 260 on maximum wattage we need a higher amount of amp on a single rail or multiple rails which have their pci e on different 12v rails it will work good :)

"Maximum load: < 210W" means MAXIMUM LOAD IS LESS THAN 210 W. And I don't think it will exceed this huge amount of power even at a GPU Boost frequency of 975 MHz.

210W on Minimum? U cannot be serious

Generall's link and a whole bunch of review website rate the minumum/idle power to be under 20W

    Did y'all see the new Assassin's Creed trailer? They finally made a AC set in Japan & then they put a negro as the male protagonist. Ubisoft is taking cues from Disney, and it isn't gonna end well for them, just like Disney. Go woke, go broke!

    if we are moving towards more and more popular trash across platforms that make billions for companies, I'm happy with all the barriers and exclusivity because at least that brings some pressure to create good stuff.
