How to compare power supplies for video editing in DaVinci Resolve without

The power supply is the one component that protects everything else, which makes the cheap unrated units a genuinely risky saving.

Quick Answer

To compare options for video editing in DaVinci Resolve without chasing hype, line up the few specs that change your day-to-day and ignore the marketing numbers. Match wattage to the GPU: a single mid-range card is happy on a quality 650W to 750W Gold unit, while a high-end RTX-class build wants 850W to 1000W. A trustworthy 650W to 850W 80 Plus Gold unit in SA runs about R1,400 to R2,800; cheap unrated 'XXXW' supplies near R500 are a false economy.

Efficiency, Noise And Warranty

The 80 Plus rating tells you how much wall power becomes usable DC and how little is wasted as heat; Gold is the value tier for most builds. A longer warranty (often 7 to 10 years on good units) signals the maker's confidence. A semi-passive fan mode keeps the build quiet at idle, which matters for late-night use.

Why Cheap Unrated Supplies Are A Trap

A R500 'XXXW' unit with no 80 Plus rating often cannot deliver its claimed wattage cleanly and skips protection circuitry. When it fails it can take other components with it, turning a saved R900 into a ruined GPU. A reputable 80 Plus Gold unit with full protection and a long warranty is cheap insurance for everything connected to it.

Buying It Right In South Africa

A good PSU protects everything connected to it; the efficiency rating and the warranty length tell you more than the headline wattage. South African buyers should confirm local stock and Evetech's carry-in warranty before checkout, since cross-border RMA on a faulty part is slow and expensive.

FAQ

Are cheap unrated power supplies safe?

No — a R500 'XXXW' unit often cannot deliver its claimed wattage cleanly and skips protection circuitry. When it fails it can damage other parts. A reputable 80 Plus Gold unit is cheap insurance for everything connected.

Should I worry about PSU noise for late-night gaming?

A semi-passive fan mode keeps the unit silent at idle and low load, which suits quiet late-night sessions. Quality Gold units run their fans slowly under typical gaming load. Pair it with a quiet cooler for a near-silent build.

Does the 80 Plus rating matter?

Yes — it tells you how efficiently wall power becomes usable DC and how little is wasted as heat. Gold is the value tier for most builds. A longer warranty also signals the maker's confidence in the unit.
