• Beneficial: 2TB NVMe PCIe 4.0 SSD
• Prime picks: Samsung 990 Professional, WD Black SN850X, Essential P3 Plus (funds)

Conventional HDDs are nonetheless helpful as secondary storage for archiving video games not presently being performed — 2–4TB HDDs price $50–80 and supply low-cost bulk storage alongside a quick NVMe major drive. For extra element see our greatest SSDs information.

6. PSU (Energy Provide Unit) — The Energy Supply

The PSU converts wall energy to the DC voltages your elements want. An undersized or low-quality PSU causes crashes, instability, and in excessive circumstances can harm elements.

Key issues to test:

• Wattage — match to your GPU’s energy necessities. For mid-range builds (RTX 5060 Ti/RX 9060 XT) a 650W PSU is adequate. For top-end builds (RX 9070 XT/RTX 5070+) goal for 750–850W.
• Effectivity score — 80+ Bronze minimal, 80+ Gold really useful for effectivity and element longevity
• Modular vs non-modular — modular PSUs solely embrace cables you want, considerably bettering cable administration
• Model — Corsair, Seasonic, and EVGA are dependable manufacturers. Don’t low-cost out on the PSU.

7. PC Case — The Housing

The case homes all of your elements and determines airflow high quality, construct problem, and aesthetics. Key issues:

• Kind issue — should assist your motherboard measurement (ATX, mATX, or ITX)
• Airflow — search for mesh entrance panels and good fan mount positions
• GPU clearance — test most GPU size vs your GPU’s bodily size
• CPU cooler clearance — test most CPU cooler peak
• Cable administration — good circumstances have routing channels behind the motherboard tray

Prime mid-tower picks in 2026: Fractal Design Pop Air (~$90), Lian Li Lancool 216 (~$100), Corsair 4000D Airflow (~$100). For extra element see our PC case information.
