The Thermaltake Smart 700W is a standard ATX power supply from the Smart Series, which Thermaltake lists as covering 500W to 700W. It is aimed at mainstream PC builds that need a dependable, non-modular supply with a quiet fan.
What the 700W figure and 80 PLUS certification mean
The 700W figure is the maximum continuous output listed. The supply is 80 PLUS certified, which means it meets a minimum efficiency at set loads. Thermaltake lists efficiency of 80-87% across 20-100% load, and up to 86% in its description. A more efficient unit wastes less energy as heat. The listing title mentions the basic White level of 80 PLUS, the entry tier of the programme.
Single +12V rail
Modern PCs draw most of their power from the +12V output, which feeds the processor and graphics card. Thermaltake describes a single +12V rail design for stable, continuous power. A single rail means the full capacity is available to any component, with no split limits to manage.
Active PFC and input range
Active power factor correction improves how the supply uses mains power. The listed input range is 100-240 VAC at 50-60 Hz with a maximum input current of 12A, so it suits different regions' mains, though you should check the plug and the switch on the unit. Thermaltake also lists a hold-up time of at least 16 ms at 60% load.
Cooling and noise
A 120mm fan, listed at 1800 RPM ±10%, cools the unit. Thermaltake describes the fan as ultra quiet and says it delivers excellent airflow at a low noise level. Fan noise typically depends on load and the case's airflow.
Connectors and size
The listing gives PCI-E 6+2 pin x 2 connectors. The unit follows the Intel ATX 12V 2.3 standard, measuring 86 x 150 x 140 mm. Safety approvals listed are CE, CB, TUV, UL and FCC. A five-year warranty is listed.
Who it suits
It suits general-purpose desktop builds, office PCs, and systems with a mid-range graphics card. It is an older ATX 12V 2.3 design, so it does not include the newest high-power graphics connector found on recent supplies.
What to check before you buy
- Total power: add up your parts' expected draw and leave headroom.
- Graphics connectors: make sure two PCI-E 6+2 pin connectors cover your card.
- Cabling: confirm the cable lengths and the number of drive connectors.
- Case fit: confirm the case takes a standard ATX unit of these dimensions.
- Standards: check the motherboard's power connector requirements.
- Local codes and the manual: follow the manual for installation and safe handling.
