How to Choose a Power Supply for Your PC — Wattage Guide Philippines 2026
Share
The power supply unit (PSU) is one of the most important components in your PC — yet it's often the most overlooked. A cheap, unreliable PSU can damage every other component in your system. Here's how to choose the right one for your build in 2026.
Why PSU Quality Matters
Your PSU delivers power to every component in your PC. An unreliable one can cause random crashes, data corruption, and in extreme cases, damage your GPU, motherboard, or CPU. A quality PSU from a reputable brand with proper protection circuits is non-negotiable — don't cut corners here.
How Much Wattage Do You Need?
Calculate your system's power draw and add 20–30% headroom for efficiency and future upgrades.
Estimated Power Draw by Component (at load)
| Component | Typical Power Draw |
|---|---|
| Ryzen 5 / Core i5 CPU | 65–125W |
| Ryzen 9 / Core i9 CPU | 125–253W |
| RTX 3060 / RX 6600 XT GPU | 100–160W |
| RTX 3080 / RX 6800 XT GPU | 200–320W |
| RTX 4080 / RX 7900 XT GPU | 280–350W |
| RAM (per 16GB kit) | 5–10W |
| SSD (NVMe) | 3–10W |
| Case fans (per fan) | 2–5W |
| Motherboard | 50–80W |
Recommended PSU Wattage by Build Tier
- Budget build (no dedicated GPU or GTX 1650): 450–550W
- Mid-range (RTX 3060/3070, RX 6700 XT): 650W
- High-end (RTX 3080/4070 Ti, RX 6800 XT): 750–850W
- Flagship (RTX 4090, RX 7900 XTX): 1000W+
Understanding 80 PLUS Efficiency Ratings
80 PLUS certification measures how efficiently a PSU converts AC power from your wall to DC power for your components. Higher efficiency = less wasted energy as heat = lower electricity bills.
- 80 PLUS Bronze: 82–85% efficient. Entry level — acceptable for budget builds.
- 80 PLUS Gold: 87–90% efficient. The sweet spot — great efficiency at a reasonable price. Recommended for most builds.
- 80 PLUS Platinum: 90–92% efficient. For power users who run their PC all day.
- 80 PLUS Titanium: 92–96% efficient. Premium tier — significant cost premium for marginal real-world savings.
Modular vs Non-Modular PSUs
- Non-modular: All cables are permanently attached. Cheaper but messier cable management.
- Semi-modular: Essential cables (24-pin, EPS) are attached; extras are detachable. Good balance.
- Fully modular: All cables detach. Cleanest builds, easier installation — worth the premium for windowed cases.
