Power and heat
Finally, let’s take a look at the GTX 1080’s power and thermal results.
The EVGA GTX 1080 consumes quite a bit more power than the GTX 1080 Founders Edition, but that’s to be expected with its beefy overclock, additional fans, and extra 8-pin power slot. That said, even when EVGA’s card is cranked to over 2GHz, it still draws roughly as much power as AMD’s Fury and far less juice than the Radeon R9 390X. AMD’s current cards are absolute power hogs.
It’s worth noting that our power and temperature tests represent a worst-case scenario, pushing graphics cards to their limits. Power is measured by plugging the entire system into a Watts Up meter, then running a stress test with Furmark—which Nvidia calls “a power virus”—for 15 minutes.
That obviously inches our maximum temperature readings upward too, which are taken during that Furmark run using both the software’s built-in tool as well as Speedfan.
It’s worth noting once more how efficient EVGA’s ACX 3.0 cooling solution is. With its out-of-the-box overclock, the EVGA GTX 1080 FTW runs cooler than the GTX 1070 Founders Edition despite drawing 100 more watts. When we manually maxed out the card at 2113MHz, it still ran cooler than the stock GTX 1080 Founders Edition. And again, these numbers are the absolute worst-case scenario. Even at 2GHz, the EVGA GTX 1080 FTW hit 74 degrees Celsius in The Division, and 68 degrees in Far Cry Primal.
This air cooler does its job and does its job well, in other words—though the closed-loop liquid cooling integrated into AMD’s Fury X naturally runs even colder. The EVGA GTX 1080 FTW’s awesome cooling pays clear performance dividends, allowing the card to run at higher clocks much more consistently than the GX 1080 Founders Edition, which starts throttling the second you overclock it if you don’t tinker with fan speeds.
Final page: The bottom line
EVGA GTX 1080 FTW
This is the GeForce GTX 1080 you’ve been waiting for. The EVGA GTX 1080 FTW puts EVGA's personal touch on Nvidia’s beastly card, and it's a winner, from its high base clock and custom cooling to its extra 8-pin power connection.
- Dual 8-pin connections amps up the potential for lofty overclocks
- Efficient ACX 3.0 cooling
- Overclocked in excess of 2.1GHz on air
- Outstanding performance on all benchmarks
- Requires a little more power than the Founder's Edition
