- ✓ 700W with 80 PLUS White certification, up to 86% efficiency

- ✗ ATX 12V V2.3 spec, not the newer ATX 3.x with 12VHPWR
Manufacturer description
The Thermaltake Smart 700W is a budget ATX 12V V2.3 power supply built around a single +12V rail, which keeps voltage delivery consistent when a modern GPU spikes under load rather than splitting current across multiple rails. Thermaltake rates it 80 PLUS White certified with efficiency up to 86 percent, so less of the wall draw is wasted as heat inside your case. A 120mm cooling fan handles thermal management and is tuned for low noise, and the compact 86mm x 150mm x 140mm (3.39in x 5.91in x 5.51in) chassis follows the standard ATX footprint that drops into most mid-tower cases without…
SpecPicks Verdict
SpecPicks scored Thermaltake Smart 700W 80+ White Certified PSU using a rating × review-volume × price-fit model applied to published specs and reviews across the power supplies category. Thermaltake's power supplies lineup sits within the broader category mid-tier; price and specs are the deciding factors over brand loyalty here.

Frequently Asked Questions
Is 700W enough for my gaming PC?
700W covers a mainstream build with one CPU and one mid-range GPU, which is the load Thermaltake designs the Smart Series around. Add up your CPU and GPU manufacturer TDP figures and leave 30% headroom; high-draw flagship GPUs will want more than this unit provides.
Is the Thermaltake Smart 700W modular?
No. This is a non-modular unit, so all cables are permanently attached to the PSU. Plan cable-management space behind the motherboard tray for the connectors you do not use.
How loud is the fan?
It uses a 120mm fan that Thermaltake specifies for excellent airflow at an exceptionally low noise level. Larger fans move the same air at lower RPM than the 80mm fans found in older budget units, which is where the noise reduction comes from.
What warranty does it come with?
Thermaltake lists a 5-year warranty on this model. Confirm registration requirements and current terms on the product listing before you buy, since warranty policies vary by region and retailer.
Will it fit in my case?
The unit measures 3.39 x 5.91 x 5.51 inches (86 x 150 x 140 mm), which is the standard ATX PSU footprint. Any case with an ATX power supply bay will take it, though check depth clearance in compact mini-tower builds.
