"This "power" control option, doesn't tweak the voltage. It just increases the limit of power from the PSU that the GPU can accept. Which means if the card needs to draw more power for a demanding game, it will be possible to do so if you increase the power limit from this setting. This is totally independent from voltage tweak/ overclocking. It helps your gpu perform better though. If you increase the memory and clock frequencies too you can achieve a good overclocking with default voltages."
Priklad na inej karte ale princip rovnaky:
"The maximum board power roughly 75 Watt however the 7870 is configured at a 140W TDP. By increasing the power slider towards 20% you increase the board TDP 140(W) x 1.20(MP) towards 175 Watt, this gives you more overclocking headroom as the card may now deliver more power throughout the board."
Takze ak by si chcel setrit energiou das to do - cisel (napr. v notebooku a podobne) cim sa ti ale znizi vykon. Ak chces pretaktovat das to do +.
Je to rovnake ako Nvidia Power Limit. Neukazuje to spotrebu ale nastavenie power limitu. Inymi slovami ak nejdes robit OC, nesahaj nato a nechaj 0%
