Manufacturer description
The Thermaltake Smart 500W is a budget ATX power supply built for mainstream desktop builds that need dependable, no-drama wattage rather than headroom for a high-end GPU. It delivers 500W of continuous output at 40 degrees Celsius, so the rating holds up inside a warm case instead of only on a cold bench. The single +12V rail design keeps voltage steady when your CPU and graphics card ramp at the same time, and two PCIe 6+2-pin connectors cover a mid-range card without adapters. 80 PLUS White certification puts efficiency around 80 percent under typical load, with Thermaltake citing up to…
SpecPicks Verdict

Frequently Asked Questions
Is 500W enough for a gaming PC?
It suits a mainstream build: a mid-range CPU plus a card that draws under roughly 200W. The two PCIe 6+2-pin connectors are the practical ceiling. High-end GPUs need more wattage and a 12VHPWR cable this unit does not have.
What does 80 PLUS White certification mean here?
It certifies about 80 percent efficiency under typical load, the entry tier of the 80 PLUS program. Thermaltake lists up to 86 percent efficiency across the Smart series. Bronze and Gold units run more efficiently but cost more.
How long is the warranty?
Thermaltake lists a 5-year warranty on this Smart 500W unit, and rates it at 100,000 hours MTBF. Check the product listing for current warranty terms and registration requirements in your region.
Is this power supply modular?
No. The Smart 500W is a fixed-cable unit, so unused connectors stay attached and need routing behind the motherboard tray. That is typical at this price, but plan cable management in a compact case.
How loud is the 120mm fan?
Thermaltake specifies a 120mm fan tuned for low noise at typical load. Noise is not a common complaint, though any fan gets louder as the unit runs closer to its 500W ceiling.
