System configuration

This GRI gaming desktop ships with an Intel Core i9 12th Gen processor and a GeForce RTX 4070 12GB graphics card inside a Zalman T3 Plus chassis. It includes a Silicon Power 1TB NVMe drive and Windows 11 Pro pre-installed. The system is aimed at enthusiasts who want to supply their own DDR4 memory.

Memory requirement

The motherboard uses a B660M chipset with DDR4 slots and the unit ships without any RAM installed. You must provide compatible DDR4 modules before the PC will boot. This approach lets you choose capacity and speed to match your budget.

Compatibility checks

Verify that your DDR4 modules suit the B660M board and that the 650W power supply covers your planned configuration. The case measures 422x206x355 mm and includes three 120 mm fans plus a Cooler Master or equivalent CPU cooler. Front I/O offers two USB 2.0 and one USB 3.0 port alongside 3.5 mm audio jacks.

Questions about this item

Will the 650W power supply need upgrading if I add more storage or a second GPU later?

The included 650W unit powers the i9-12900K and RTX 4070 12GB as shipped; adding a second high-end GPU would likely exceed its capacity, while extra NVMe drives add minimal draw.

What thermal limit appears first when the i9-12900K and RTX 4070 run sustained loads in the Zalman T3 Plus case?

The air cooler and three 120mm chassis fans must dissipate both the 12900K and 4070 heat; CPU core temperatures typically hit throttle thresholds before GPU limits under prolonged all-core workloads.

How loud are the three 120mm chassis fans and CPU cooler when the system runs all day under load?

The Zalman T3 Plus relies on three 120mm case fans plus a Cooler Master or equivalent CPU cooler; expect audible but not extreme airflow noise during extended gaming or rendering sessions.
