I have been looking at 3 cards for my system, although I am not sure whether I completely understand what these cards could mean for my monthly power bill. Here are the cards and the respective peak watts of the system under load (and in idle state).
MSI 7970 Lightning
- Load: 412 (Idle: 164)
MSI 680 Lightning
- Load: 363 (Idle: 155)
MSI 670 Power edition
- Load: 329 (Idle: 155)
These numbers were taken from Hardware Canucks. All three cards were tested in an identical system:
Processor: Intel i7 3930K @ 4.5GHz
Memory: Corsair Vengeance 32GB @ 1866MHz
Motherboard: ASUS P9X79 WS
Cooling: Corsair H80
SSD: 2x Corsair Performance Pro 256GB
Power Supply: Corsair AX1200
Monitor: Samsung 305T / 3x Acer 235Hz
OS: Windows 7 Ultimate N x64 SP1
My system is different, as you can see in my sig rig; I assume my system uses less power when running either one of these cards.
Now, can anyone help me understand how the difference in power consumption of each of these cards affects my monthly bill? I have also read that the 7970 is a power hungry card but does it really make a big difference if the card uses 49 watts more under load (see above 680 vs 7970 Lightning)?
Please, bear in mind that I am not asking for advice on choosing a video card; I simple want to get a better understanding of what the difference in power consumption means and how much it possibly could affect my wallet.
