Signature Series
ZTK Obsidian Black Model
Blacked-out, purple-lit 1440p.
On the bench — building now
A blacked-out, purple-lit RGB showcase in the ASUS ROG Strix Helios — a Zen 5 Ryzen 5 9600X and an EVGA RTX 3070 FTW3 Ultra tear through high-refresh 1440p with ray tracing and DLSS, on the future-proof AM5 platform (DDR5-6000, PCIe 5.0, Wi-Fi 7). Liquid-cooled by a 360 AIO with a 4-inch live display and lit edge-to-edge by infinity-mirror ARGB behind smoked tempered glass. Hand-built in Cutler Bay — currently on the bench.

Anatomy of the build
Every part, chosen on purpose.
No filler, no leftover stock. Here's exactly what goes into the ZTK Obsidian Black Model — and why we picked it.
The chassis
ASUS ROG Strix Helios GX601 RGB
The Obsidian's shell is the ASUS ROG Strix Helios — a premium aluminum-framed showcase in brushed black, with 4mm smoked tempered glass across the front and both sides for a full, unbroken view. The Aura Sync RGB front panel glows the ROG cyber-text in purple to match the build, GPU support braces hold the 3070 dead level, and it swallows up to a 420mm radiator. Four 140mm fans come pre-installed on a built-in hub. A genuine flagship case — built to be seen from every angle.

Graphics
EVGA RTX 3070 FTW3 Ultra
The engine — an EVGA RTX 3070 FTW3 Ultra, one of the best-cooled 3070s ever made. 8GB GDDR6 and Ampere RT cores deliver high-refresh 1440p with ray tracing and DLSS, while the iCX3 triple-fan cooler stays cool and quiet. ARGB across the top edge glows purple to match the build, with a full metal backplate for rigidity.

Power
Rosewill VMG 750W · 80+ Gold
