MSI GTX 750 Ti Gaming OC
MSI´s GTX 750 Ti Gaming follows Nvidia’s reference design, forgoing an auxiliary power connector. But it does include an oversized cooler, which probably could have cooled the 60 W GM107 GPU passively.
Even still, MSI’s configuration doesn’t have to get very loud to do its job well; the card never gets hotter than 51-52 degrees Celsius, and fan speeds top out between 32 and 33 percent. That also means noise under load is barely louder than at idle. In fact, our acoustic measurements don’t even appear plausible because the differences fall within the tolerances of our hardware.
As usual, GPU-Z provides us an overview of the card’s specifications:
Gigabyte GTX 750 Ti Windforce OC
Here’s Gigabyte’s GTX 750 Ti Windforce OC. The company similarly leans on Nvidia’s reference PCB. However, it also exploits the solder points for a six-pin auxiliary power connector, yielding potentially better overclocking headroom.
Zotac GTX 750 Ti OC
Zotac’s GTX 750 Ti goes the same route as MSI’s, forgoing the six-pin power connector in favor of a design driven exclusively by a 16-lane PCI Express slot. It is built on the same reference PCB though, and is the only model employing a single-fan cooler.
