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 Gigabyte GeForce RTX 3050 Gaming OC now plays in the league of small cards, which gives the all-clear because the card is (almost) fully utilized even in Full HD. If you now add up the power consumption in Full HD, which I measured in all games over the entire runtime, then everything is back to a very ample 130 watts for the TBP. First of all, the respective average over all resolutions, games and graphics cards:
The slightly worse voltage converters also result in a slightly worse efficiency of the card, which does not look quite as good as that of the GeForce RTX 3060 FE in the launch article at the time. In turn, MSI’s Gaming X can do that much better, while the Palit RTX 3050 Dual OC scores even slightly worse.
There are actually no big secrets when it comes to the power consumption in the individual scenarios, because what NVIDIA specifies as TBP for the GeForce RTX 3050 is also largely adhered to and even undercut during gaming. With plenty of 12 watts at idle, it is still within a usable range. It is certainly also due to the RGB of the board partner card and Holtek’s ARM processor that it is not less. The partial load ranges are still adequately realized, which could also be due to the slightly increased clock rate. However, the card still reaches around 134.2 watts during real full load in WQHD and full heating, which is a bit more than specified 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 the maximum and minimum values. A maximum of 164 watts power limit is allowed instead of the 130 watts for the board partner card, instead of the 140 watts at MSI and the 150 watts at Palit, which can be accessed with the appropriate software, but is also completely pointless since it hardly changes anything in terms of performance. Then, unfortunately, the card fails in itself.
Let’s now look at the load of the motherboard slot, which is specified by the PCI SIG as 5.5 amps. This results in a maximum power of 66 watts at 12 volts. You can see very clearly that this limit is undercut very significantly under full load with 3.1 to 3.4 A, even if you exhaust the maximum power limit. The fact that the 8-pin connector is only routed to three and the PEG to one phase of the GPU is thus completely sufficient and the balancing is also completely okay.
The slightly more detailed curve for gaming and torture looks like this, although the intervals with the long 20 ms are still very granular.
