True 4k Gaming PC (2026) - Classic LTT Build Guide

CPU and Motherboard Selection [00:32]

• The Intel Core Ultra 250 KF Plus is chosen for its value in gaming, featuring 6 performance cores and 12 efficient cores.
• The F variant is selected to save money by omitting integrated graphics.
• ASRock's B860M ProA motherboard is selected for its reasonable price and essential features like solid power delivery and 2.5 gig networking.

Storage and RAM Installation [03:28]

• A 1TB Patriot P300 NVME SSD is installed for fast storage, placed in a slower slot to reserve the faster slot for future upgrades.
• The process involves aligning the NVME drive with the motherboard slot's notch and securing it with a clip.
• 32GB of DDR5 RAM is discussed, with a placeholder kit used due to the original not arriving in time.
• RAM installation requires aligning the notch and pushing down until it clicks, emphasizing consulting the motherboard manual for correct slot placement (typically slots 2 and 4).

CPU Cooler and Case Preparation [06:23]

• The Thermalite Assassin X120 refined SE cooler is chosen for its affordability ($17.90) and ability to handle the CPU's thermal load.
• Installation involves using the LGA1700 mounting instructions due to shared specifications with the LGA1151 socket.
• The process includes attaching the backplate, spacers, Intel screws, and mounting brackets before applying thermal paste and screwing down the cooler.
• The Gambas Athena M4M case is introduced as a budget-friendly option with ample space for components.

Motherboard and Wiring Installation [08:42]

• Motherboard standoffs are checked to ensure correct alignment with the motherboard's mounting holes.
• The IO shield is installed at the back of the case, requiring firm pressure on its corners.
• The motherboard is carefully placed onto the standoffs, aligning the rear IO ports.
• Front panel wiring, including audio, USB 3 Type-A, and USB Type-C connectors, is routed to the appropriate headers on the motherboard.
• Front panel buttons and LEDs are connected, noting that polarity doesn't matter for the power button.

Power Supply and GPU Installation [11:28]

• The CSIC Focus GXV4 ATX3 850W 80 Plus Gold power supply is highlighted for its modularity, reliability, and 10-year warranty.
• Necessary cables (24-pin motherboard, 8-pin CPU, 4-pin CPU, PCIe for GPU, SATA for hub) are connected to the power supply before installation.
• The power supply is mounted in the case with the fan facing the side panel.
• The ASUS Prime GeForce RTX 4070 Ti 16GB GPU is installed, requiring the removal of PCIe slot covers.
• The GPU is seated in the PCIe 16X slot and secured with its power connector.

Final Assembly and Testing [15:27]

• Excess cables are tidied using straps on the back of the motherboard tray.
• The system is powered on, and XMPP is enabled to ensure optimal RAM performance.
• Gaming benchmarks are shown for Cyberpunk 2077 and Forza Horizon 6, demonstrating smooth 4K gameplay with high settings and ray tracing enabled.
• The build is praised for its quiet operation and overall performance, achieving under $2,000 total cost.
