Quick Answer

For most video editing builds, a quality 750W 80+ Gold PSU handles a Ryzen 9 or Core i7 paired with an RTX 4070 comfortably. Step up to 850-1000W if you are running an RTX 4080/4090 or planning multi-GPU rendering.

Calculating Your Editing Rig's Real Draw

Video editing is bursty. Timeline scrubbing in Premiere or DaVinci Resolve might pull 200W, but the moment you hit Render or run a GPU-accelerated NeatVideo denoise, your system spikes to 80-90% of peak. A typical RTX 4070 plus Ryzen 7 7800X3D editing build pulls around 480-520W under full export load. Adding capture cards, extra NVMe drives, and monitor backlight all chips away at headroom. The smart play is sizing your PSU so peak draw lands at 60-70% of rated output, that is the sweet spot for efficiency and silence.

Recommended Wattage by Build Tier

For a R25,000 entry editing rig with an RTX 4060 and Ryzen 5, a 650W 80+ Gold unit is plenty. The R45,000 mid-tier RTX 4070 Ti Super build wants a 750W. Top-tier RTX 4090 workstations need 1000W minimum, with 1200W recommended if you are running ProRes hardware acceleration cards alongside. Loadshedding is a real factor here too, a quality PSU rides UPS switchover transitions far better than a cheap one. Browse our PSU range filtered by 80+ Gold or higher only.

What Editors Often Get Wrong

Stop sizing PSUs by adding spec sheet TDPs. GPU transient spikes can hit 1.8x rated TGP for milliseconds, and a borderline PSU will trip its overcurrent protection mid-export. Pick ATX 3.0 / PCIe 5.0 ready units if you are on a 40-series or 50-series GPU, the native 12V-2x6 connector is tidier and avoids melting adapter risk. Modular cabling makes cable management in render-heavy builds far easier and improves airflow during long timeline exports.

Frequently Asked Questions

Is 600W enough for editing 4K footage on an RTX 4060?

Yes, a quality 600W 80+ Gold PSU handles an RTX 4060 plus Ryzen 5 7600 editing build with around 30% headroom for spikes.

Do I need a higher wattage PSU for AV1 encoding workloads?

Not specifically. AV1 encode uses GPU media engines which are very power efficient. Your existing PSU sized for gaming will cover it.

Will an undersized PSU damage my editing rig?

A good PSU shuts down safely under overload. A budget unit may push dirty power into your components, which over time can degrade your motherboard VRMs and shorten SSD life.
