ASUS Poseidon GTX 780 Video Card Review


Temperature & Noise Testing

Temperatures are important to enthusiasts and gamers, so we took a bit of time and did some temperature testing on the ASUS Poseidon GTX 780.

ASUS Poseidon GTX 780 3GB Temps:



At with the boards air cooling solution we got 25C at idle and hit a high of 72C when gaming. GPU-Z shows that the ASUS Poseidon GTX 780 video card had an GPU voltage of 0.875V at idle and 1.158V when at full load gaming. The fan speed at idle was 1028 RPM and 2153 RPM at load when gaming.


Sound Testing

We test noise levels with an Extech sound level meter that has 1.5dB accuracy that meets Type 2 standards. This meter ranges from 35dB to 90dB on the low measurement range, which is perfect for us as our test room usually averages around 36dB. We measure the sound level two inches above the corner of the motherboard with ‘A’ frequency weighting. The microphone wind cover is used to make sure no wind is blowing across the microphone, which would seriously throw off the data.


The ASUS Poseidon GTX 780 was fairly quiet and ran at 39.3 dB when at idle and hit 49.4 dB when gaming.
