Let’s first consider what the BIOS of this map gives us as corner and limit values:
This results in a maximum power consumption during gaming of 182 watts over 2 minutes of measurement time at intervals of 20 ms. Interestingly, this is 7 watts above the value specified in the BIOS for the card (TBP), which the manufacturer can claim as a tolerance range for the rather inaccurate Inductor DCR. I wouldn’t call it cheaten now, but i’m sure it could have been done more closely if it had been applied to it. The customer is of course happy about this.
I measured up to intervals of 0.5 ms to analyze the load peaks and to get an overview of the behavior of the control. The area relevant for the power supply protection circuits from approx. I have shown 10 ms again in the following table.
| Power Limits according to BIOS: |
125 Watt Minimum 175 Watt Default 175 Watt Maximum 0 Watt overclocking reserve |
| Power consumption (measured) |
14 Watt Idle 25 Watt Multi-Monitor (identical monitors) 134 Watt Workstation Graphics (OpenGL) 182 Watt Gaming 186 Watt Maximum (OC) |
| Load peaks (>=10 ms) |
212 watts |
| Power supply recommendation | proportionally 250 watts to 12 volts for the entire graphics card |
| Motherboard load | < 3,5 Ampere 3,5=””></ 3,5 Ampere> |
| Phase splitting (PEG/PCIe) | 1 + 4 |
| Coil feathers | hardly to not audible |
