Modular vs. Non-Modular PSU – What’s Better for Your Build?
Modular PSUs, like the Corsair RM750x Shift, let you detach unused cables, improving airflow (up to 10% better in compact cases) and simplifying cable management for clean builds. They’re ideal for RTX 4080 setups but cost 10–15% more (~$100–$140). Non-modular PSUs are cheaper (~$80) but clutter cases with fixed cables, potentially raising temps by 2–4°C. Semi-modular PSUs, like the Thermaltake Toughpower GF1 750W, balance cost and flexibility with fixed essential cables (e.g., 24-pin) and detachable extras (e.g., PCIe).
Recommendation for 2025: Choose fully modular PSUs for gaming power supplies supporting RTX 4080 or RX 7900 XTX to ease upgrades and enhance aesthetics. Budget builds can opt for semi-modular like the MSI MAG A750GL.
What Does 80 Plus Gold Really Mean?
80 Plus Gold certification ensures ≥87% efficiency at 20% and 100% load, and ≥90% at 50% load (115V), cutting energy waste by ~15% vs. Bronze units, saving ~$8–$15/year (500W load, 12¢/kWh). This reduces heat output, extending component life. All our picks are 80 Plus Gold, with models like the Seasonic Focus GX-750 hitting Cybenetics Gold (>90% efficiency) and A+ noise (<10 dBA at 50% load). For gamers, this means stable power for RX 7900 XTX, with <100µs transient recovery and minimal noise.
Buying Guide: Choosing the Right 750W PSU for Your Build
