Power consumption and compliance with standards
The maximum values of a very demanding scene are not the whole truth, because the power consumption of fast cards is actually very resolution-dependent. However, the new GeForce RTX 3060 is known to play in the league of smaller cards, which gives the all-clear when it comes to CPU bottleneck. What this means in detail, I had already analyzed when it came to the combined power consumption with the CPU and their individual listings. If you also add up the power consumption in WQHD, which I measured in all games over the entire runtime, then everything is back at the stated (just under) 170 watts for the TBP, so precision landing, because the CPU does not limit here. First of all, the respective average over all resolutions, games and graphics cards:
There aren’t really any big secrets when it comes to power consumption, because what NVIDIA specifies as TBP for the GeForce RTX 3060 is largely adhered to. With approx. 12 watts in idle one lies in the usable range, it is surely also due to the RGB of the board partner card. The partial load ranges are realized relatively sparingly, which could also be due to the moderately regulated cycle. However, the card reaches around 175 watts at real full load in Control with Ultra HD and full warming, which is 5 watts more than predicted and stated in the specs.
Which brings us to the specifications, because in the end it is clearly regulated by firmware what is possible as well as maximum and minimum. A maximum of 170 Watt power limit is allowed for this board partner card, more is not possible anyway because of the power supply.
Transients and power supply recommendation
As I have already demonstrated in detail in my basic article “The battle of graphics card versus power supply – power consumption and load peaks demystified”, higher loads in the millisecond range do exist for short periods of time, which can already lead to inexplicable shutdowns in the case of poorly designed or improperly equipped power supplies. The TBP (Typical Board Power) measured by the graphics card manufacturer or the reviewers is not really helpful for a stable system design.
Peaks with intervals between 1 and 10 ms can lead to shutdowns in very fast reacting protection circuits (OPP, OCP), especially in multi-rail power supplies, although the average power consumption is still within the norm. For this card, I would therefore calculate a graphics card load of at least 230 to 260 watts proportionate to the total system power consumption on the secondary side, in order to have sufficient reserves for the worst case scenario.
