Step by step guide for assembling a maxed-out 5090 build in the Lian-Li A4-H2O. As seen on YouTube.

This guide can be used as a reference with any 2 slot GPU that fits into the A4-H2O.

Parts List

Tools

I use the Xiaomi Electric Precision Screwdriver as my go to for all my builds - Amazon (affiliate)

For this build, I also recommend the iFixit Mako set - Amazon (affiliate)

Thermal Paste

I recommend Thermal Grizzly’s Duronaut thermal paste - Amazon (affiliate)

It has excellent performance and it’s easy to apply and clean.

Custom PSU Cables

I use custom cables from Cablester, which feature per-wire lengths for perfectly sized cable runs.

I recommend going for either “Teflon” or “Debossed” cables in a color of your choice.

The set pictured in this guide is the black debossed variant and was provided by Cablester.
