Measurement Methodology & Graphical Illustration
The measurement and analysis software we're gradually transitioning to, PresentMon, integrates a whole host of sensor data with the frame time measurements. We’re including the reader-friendly version of our oscillography measurement graphs as well, of course.
The measurement intervals are twice as long. There's also a hardware-based low-pass filter and software-based variable filter in place (the latter is a feature of the software used to analyze data; it's designed to evaluate the plausibility of very short load peaks and valleys). The resulting curves are a lot smoother than the old ones; we hope you derive more value from them as a result.
You'll find more information about our power consumption test methodology in The Math Behind GPU Power Consumption And PSUs.
You'll find a larger number of bar graphs, and higher-resolution versions of our power consumption charts that you can expand by clicking on them. We restructured our topic sections, added more comparison bar graphs, and, finally, added different scenarios to our measurements. In addition to power consumption, we also examine current to determine whether the graphics card stays within all of its relevant specifications. Our test equipment doesn't change, though:
|Power Consumption Measurement|
|Contact-free DC Measurement at PCIe Slot (Using a Riser Card)|
Contact-free DC Measurement at External Auxiliary Power Supply Cable
Direct Voltage Measurement at Power Supply
|2 x Rohde & Schwarz HMO 3054, 500MHz Digital Multi-Channel Oscilloscope with Storage Function|
4 x Rohde & Schwarz HZO50 Current Probe (1 mA - 30 A, 100 kHz, DC)
4 x Rohde & Schwarz HZ355 (10:1 Probes, 500 MHz)

Power Consumption at Different Loads
In addition to our usual measurements, we're also including some additional games, rendering paths, and quality settings. With the sole exception of Metro: Last Light, resolution is being limited to 1920x1080. These entry-level graphics cards just aren’t meant for any more than that.
This time around, we're using the values from our highest sustainable overclock to represent peak power consumption (we went as high as 1911 MHz). Nvidia's 75 W power target didn't seem to be a limiting factor; we increased the target by 25% and didn't see consumption rise at all. In other words, the 1050 Ti hit its limit at that frequency.
Let’s take a look at how total power consumption evolves during the warm-up pass.
It’s plain to see that consumption stays about the same, which tells us that there are no significant losses all the way up to the GeForce GTX 1050 Ti Gaming X 4 GB’s operating temperature.
Power Connector Load Distribution
Now we can examine power consumption more closely by looking at its distribution across two 12V rails (the motherboard slot and six-pin connector) during a realistic gaming load and a stress test.
Registering just 36 W during the stress test and 21 W while gaming, the motherboard slot is barely used. This is due to the fact that just one of the GPU power supply’s three phases (the memory modules) and the board components (fans and LED) draw from it. The other two GPU power supply phases are routed through the six-pin connector instead. And that's why MSI includes it. The 70 W that the GeForce GTX 1050 Ti Gaming X 4 GB draws at stock settings are already higher than the 66 W maximum you can see through the motherboard slot, according to the PCI-SIG’s specs.
Here are the corresponding graphs for gaming and our stress test. Click on them for a larger version.
The PCI-SIG’s specifications only apply to current, meaning power consumption results on their own don't tell the whole story. Our readings put the motherboard slot well below 3 A. Given a ceiling of 5.5 A, the card has plenty of room to spare. This is hardly surprising in light of our low power consumption measurements for this connector. The 5.5 A figure would have been slightly exceeded if it wasn't for that six-pin connector, though.
We also have larger graphs for the current measurements.
We would have loved to test GeForce GTX 1050 Ti and vanilla 1050 cards without power connectors as well, since those are the ones flirting with the motherboard slot's ceiling. But as we explained on page three, the launch sampling just wasn't what we hoped it'd be.
Power Consumption Comparison with Other Graphics Cards
Finally, we’d like to know how GeForce GTX 1050 Ti stacks up against other cards. We're using the peak power consumption numbers for this comparison because that's what we presented previously.
It’s interesting that GeForce GTX 1050 Ti Gaming X 4 GB has a high possible power target at 75 W plus 25%. However, it doesn’t use it. Due to the maximum stable clock frequency of 1911 MHz, the card starts throttling just under 75 W.
