Cheers. That means 8x50 = 400A at best for Gaming 7, while Asrock goes for 8x60 = 480A at best.

Taichi has a heatpipe going to it.



And I agree Asus has even a fan to actively cool it (both boards), while we know EK is going to release monoblock for the Zenith.

Gigabyte is using some foam between the heatsink and the chokes, which more isolates them instead of transmitting heat:

Also the author claims that those extra heatsinks connected by a heatpipe don't really help a lot.

Hi everybody !

I'm currently torn deciding between ASUS ROG Zenith Extreme & ASRock FATAL1TY.

Given their Power Phases & CPU Pin, which would you think will be the best overclocker for a 1950X under custom Watercooling ?

Asus : 8+2 PP & 8+8 Pin
ASRock : 11 PP & 8+4 Pin

I'm sorry if my question is a bit blunt, but my VRM knowledge is very limited. frown.gif

Thank you for your help smile.gif

For the ASRock it's 8 phases for VCore too.
At the moment I don't know about what the ASRock VRM is capable off under real conditions but according to OC3D the Zenith VRM is able to output 550W continuously (?) without 'getting really hot at all'.

Zenith Extreme: 8x IR3555M 60A (VDDCR_CPU), 3x TI 97374M 25A (VDDCR_SOC).
Both loops driven by their dedicated custom (ASP1405) Salem-series (IRF) controllers.
