A power supply is the one component where a bad deal can cost you a whole PC, so this page is deliberately conservative. We track live PSU deals on reputable units only: modern ATX 3.1 designs and proven Gold-rated lines from 650W to 1000W, and we score every listing against its own 30-day price history so you can tell a real discount from a strikethrough game.

Quality power supply deals arrive regularly and quietly, which makes genuine drops easy to miss and manufactured markdowns easy to fall for. The 2026 market rewards patience: the ATX 3.1 transition is complete, the good Gold platforms are mature, and they cycle through discounts every few weeks. Listings refresh throughout the day, ranked by actual savings.

PSU pricing is steady most of the year, then drops in clusters — when one vendor cuts a wattage tier, competitors usually follow within days.

Buying advice

Sizing and choosing a power supply on sale

  • Size for the GPU with headroom: 650–750W covers mid-range builds, 850W suits high-end single-GPU systems, and 1000W+ is for flagship cards and heavy overclocking. Running a PSU at ~50–60% load keeps it quiet and efficient.
  • ATX 3.1 with a native 12V-2x6 connector is worth a small premium for any current GPU — it eliminates adapter clutter and the connector concerns of the previous spec.
  • The warranty is the spec sheet's tell: 7–10 year warranties signal build quality far more reliably than the 80 Plus badge alone.
  • Fully modular is a nice-to-have, not a must. If a semi-modular unit from a top-tier line is meaningfully cheaper, take it.
  • Never stretch to a no-name brand for wattage. A quality 750W beats a questionable 1000W in every way that matters.

When to wait

If your target wattage tier hasn't dipped in weeks, a competitor drop often triggers one. But PSUs are also the part least worth gambling on — a verified deal on a known-good unit is worth taking.

Power supply deal FAQs

How many watts do I actually need?

Add your CPU and GPU's rated power, then double it as a rough guide — that lands the PSU near its efficiency sweet spot at gaming load. For most current mid-range builds that means 650–750W; high-end single-GPU systems are comfortable at 850W.

Is 80 Plus Gold worth it over Bronze?

Yes, and it's the floor for this page. The efficiency saving is modest, but Gold-rated lines from reputable brands are also where build quality, quieter fans, and longer warranties concentrate. Below that tier, quality variance gets risky.

What is ATX 3.1 and do I need it?

The current PSU spec designed around modern GPU power spikes, with the revised 12V-2x6 GPU connector. For a new build with a current graphics card it's the sensible default; for older GPUs a quality ATX 2.x unit remains fine.

Are cheap power supplies dangerous?

The bad ones can be — a failing PSU can take other components with it. That's why this tracker lists established brands with strong warranties only. A $20 saving on an unknown brand is the worst trade in PC building.

Do PSU deals recur if I miss one?

Usually. PSU pricing moves in clusters — when one brand cuts a wattage tier, competitors tend to follow within days. The 30-day history scoring here means you'll see the next genuine dip when it lands.
