Sometimes amperage capability > watts.
Not always the case thus the "sometimes"
Zens biostar gt7 has proven its worth in overclockability thus far however...especially on 1700x which i suspect is AMD's dumping grounds for crappy r7's 90w chips.
The problem with the internet today is the lack of accountability.
On pc forums User A says no its safe costs users B,C an D $600 to find out he was wrong. User A gets off scot free.
On the race car forums it is no different except $ amount. User A says turn the boost up to 26lbs. User B,C and D lifted a head gasket,cracked a piston ring, melted a piston...or worse just sent a rod through block due to detonation. $3k in damages. User A gets off scot free.
Avoid the A's they will put a hole in your wallet.
