Gigabyte PowerSupply 800W
Power Supplies
Gigabyte 800W ATX power supply — 800W continuous output with standard ATX/EPS/PCIe connectors and protection suite for mid‑to‑high‑end gaming and content builds.
Product Details
Overview
The Gigabyte PowerSupply 800W is an 800 watt ATX-format power supply designed to deliver continuous power for modern desktop PCs. At 800W it provides enough headroom for a mainstream to high‑end single‑GPU system, allowing for a beefy CPU and a discrete graphics card while leaving room for peripherals and modest overclocking.
Performance & technical details
An 800W unit targets systems where the +12V rail must reliably deliver sustained current to CPUs and GPUs. In real terms, that makes it suitable for builds with mid-to-high-end cards (for example RTX 3070/3080/4070-class GPUs) paired with 8‑ to 16‑core CPUs. Good power delivery means lower voltage ripple and stable rails under load — important during long gaming sessions, rendering or streaming. Typical modern 800W PSUs include a 24‑pin ATX main connector, one or more 4+4/8‑pin CPU (EPS) connectors and multiple PCIe 6+2‑pin connectors for graphics cards, plus SATA and peripheral outputs for drives and accessories.
Practical use cases
This 800W supply is well suited to 1440p/ultra settings gaming on a single high‑performance GPU, content creation workflows such as 4K video editing and encoding, and streaming while gaming. It gives sensible headroom over 500–650W units, which helps when you add NVMe drives, multiple case fans, or mildly overclock a CPU/GPU. It is not the ideal choice for extreme dual‑GPU rigs or the highest‑power single‑GPU setups that recommend 850W+ (for example some RTX 4090 systems).
Specs summary
- Brand: Gigabyte
- Rated output: 800W continuous
- Form factor: ATX (standard desktop PSU)
- Connectors: standard ATX 24‑pin, CPU EPS 4+4/8‑pin, multiple PCIe 6+2‑pin, SATA and peripheral connectors (typical for 800W class)
- Protection features: includes standard protection suite commonly found in quality PSUs (OVP/UVP/OPP/SCP/OTP)
- Cooling: internal fan with thermal control for balanced acoustics and airflow
Who this is best for: PC builders upgrading from a 500–650W supply, gamers running single high‑performance GPUs at 1440p, content creators working with 4K editing and encoding on a single‑GPU workstation, and general enthusiasts who want stable power with modest overclocking headroom. Not recommended for extreme multi‑GPU builds or systems explicitly requiring 850W+ recommended power.
