Ready-to-game desktop with i7-12700K and RTX 4070

This GRI system ships with an Intel Core i7 12700K processor and a GeForce RTX 4070 12GB graphics card installed. Windows 11 Pro is pre-activated and updated. The 1TB NVMe SSD provides storage for games and applications. It is aimed at builders who want a tested platform but prefer to supply their own DDR4 memory.

BYOR DDR4 on a B660M board with 650W power

The motherboard uses the B660M chipset with DDR4 slots and arrives without RAM, so you install the capacity and speed you choose. A 650W power supply feeds the CPU and GPU with headroom for additional drives. Front I/O includes two USB 2.0 ports, one USB 3.0 port, and separate 3.5mm headphone and microphone jacks. Wi-Fi 6 and WiFi 6E are built in for wireless connectivity.

Air-cooled Zalman T3 Plus chassis under sustained

Three 120mm chassis fans and a Cooler Master or equivalent CPU cooler move air through the frameless tempered-glass side panel. The case measures 422x206x355 mm and uses air cooling rather than liquid. Rear I/O provides six USB ports for peripherals. This configuration suits users who accept fan noise during long sessions; it is not for buyers who want silent liquid cooling or a smaller footprint.

Questions about this item

What thermal limit does the 650 W power supply and air cooling hit first when the i7-12700K and RTX 4070 run at full load?

The 650 W supply and air cooler are sized for the i7-12700K and RTX 4070 combination; sustained full load stays within the unit's thermal and power envelope.

How loud and hot does the Zalman T3 Plus case get with three 120 mm fans and the Cooler Master CPU cooler running all day?

Three 120 mm chassis fans plus the Cooler Master CPU cooler move enough air to keep temperatures stable and noise at a typical desktop level during extended sessions.

Which DDR4 memory kits and how many modules do I need to install before this BYOR system will boot?

The B660M motherboard accepts standard DDR4 DIMMs; populate at least one slot with a compatible kit to complete the build.
