Let’s start with the individual loads and the resulting power consumption in each case. The approx. 12 watts in idle are okay, after all, the fan is also running permanently. The rest is in the gradation as before. With about 230 watts, the card isn’t a costly one, but it’s still within the bounds of what’s bearable and, on balance, more efficient than the new Radeon Pro W6800. This is remarkable in that the Radeons are considered more efficient than most GeForce equivalents in this performance class.
A maximum power limit of 230 watts is stored in the BIOS, which is de facto never exceeded.
Standard compliance at the motherboard slot (PEG)
Now let’s look at the load of the motherboard slot, which is specified by the PCI SIG with 5.5 Amps. This results in a maximum power of 66 watts at 12 volts. You can see very clearly that under normal load exactly 5.4 to 5.5 amps are reached, which is exactly on the maximum limit of what is allowed and does not allow any further leeway. But the balancing here is really optimized to keep the 8-pin connector at least close to the norm.
Power supply load in detail
Before we deal with the load peaks and the power supply recommendation in the next chapter, I have recorded two minutes higher resolution for you, whereby here the interval is at the magic 20 ms, which is already interesting for power supplies (shutdown). The following graphics include a complex CAD 3D loop (Maya 2021) and the Torture Test (Furmark, OpenGL).
