Nvidia Promises To Fix Excessive GPU Power Use Issue At High Refresh Rates
PC Perspective recently discovered something quite intriguing and somewhat disturbing when it comes to some recent Nvidia GPUs when paired with gaming monitors. While testing out the Asus PG279Q, the guys over at PCP found out that when the refresh rate is set higher than 120Hz, the power usage of the entire system increases considerably without any reason even when idling.
According to the site, their test system with its GTX 980Ti GPU idles at around 75W, however with PG279Q connected to the system, the idle power consumption climbs as refresh rate is increased and goes up to a massive 200 watts. It seems as if the 980Ti clock speed automatically starts increasing as the refresh rate exceeds 120Hz therefore drawing more power.
Nvidia responded to the issue in a statement and acknowledged the issue, which can be a pretty big one if someone is using their PC at a refresh rate of around 165Hz and don’t have a lot of overhead available through their power supply.
The company has assured that they are working on fixing the bug and a future driver release should solve the problem, however, they haven’t clarified the exact reason of the issue.
The full statement from the GPU manufacturer can be seen here and it is best for users to not exceed 120Hz refresh rate until the issue is fixed in order to not only save electricity costs but also protect their expensive GPU.
