Best Modular Power Supplies 2026

Aktualisiert 2026

Fully-modular PSUs have become the default in 2026 — cable-management aesthetics, easier builds, and easier upgrades. We tested 50 power supplies for sustained load efficiency, ripple suppression, coil whine, fan noise, and warranty terms. These are the ten best modular PSUs for 2026.

So bewerten wir

Modular PSU scoring measures sustained load efficiency at 50% (the real-world operating range), 80 Plus certification accuracy in real testing (not just sticker), ripple and voltage stability at full load, fan noise profile across load curves, cable quality and length, ATX 3.1 compliance for current GPUs, and warranty length. We penalise PSUs with proprietary connectors.

Häufig gestellte Fragen

What is the best modular PSU in 2026?

The MSI MAG A750GL 750W ATX 3.1 leads our 2026 ranking on value at $49 — 80 Plus Gold efficiency, full modular cables, ATX 3.1 compliance for RTX 50-series. For higher-wattage builds, the Corsair RM850e or NZXT C 850W Gold deliver flagship reliability with 10-year warranties.

How many watts do I need?

RTX 5070 + Ryzen 7: 750W is the comfortable floor. RTX 5080 + Ryzen 9: 850W. RTX 5090 + high-end CPU: 1000W minimum, 1200W safer with peak transients. Don't over-buy — a 1500W PSU running a 300W system wastes efficiency since most PSUs are most efficient at 40-60% load.

80 Plus Gold vs Platinum vs Titanium?

For most home use, Gold is the sweet spot — Platinum saves 2-3% efficiency at 30-40% load price premium, Titanium another 1-2% at significant cost. Worth Platinum only if you run the PC 24/7 or pay >$0.25/kWh electricity. Gold suffices for 95% of builds.

Is ATX 3.1 important in 2026?

Yes for RTX 50-series GPUs. ATX 3.1 handles the high transient spikes (up to 200% rated power for milliseconds) that modern GPUs draw. Older ATX 2.x PSUs may trigger over-current protection on RTX 5080/5090 even when total wattage is sufficient. Look for ATX 3.1 + 12V-2x6 connector.

Fully modular, semi-modular, or non-modular?

Fully modular wins on cable management and upgrade flexibility — only use the cables you need. Semi-modular saves $10-20 with fixed motherboard and CPU cables (always-used anyway). Non-modular saves another $20 but creates cable clutter that affects airflow. Fully modular is worth the upcharge in 2026.
