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 MSI GeForce RTX 3050 Gaming X 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, everything comes back to just under 130 watts for the TBP. First of all, the respective average over all resolutions, games and graphics cards:
The slightly better voltage converters also result in a visibly better efficiency of the card, which now even looks a bit better than the GeForce RTX 3060 FE of the launch article at that time. This is because the gaming performance even increases slightly with slightly lower power consumption.
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 11 watts at idle, it is within a usable range. It is certainly also due to the board partner card’s RGB 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 133.6 watts under real full load in the stress test and full warming, which is only slightly 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 140 watts power limit is allowed for the board partner card instead of the 130 watts ex-factory (Palit 150 watts), which can be accessed with the appropriate software, but is also somewhat pointless since it hardly changes anything in terms of performance. MSI has still delivered the slightly faster card with a 10 watt lower limit. Chapeau!
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 3.3 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.
