120 W 10 A desktop power supply or PTA-120W-12V Two models side by side: measurements taken by the author in their reviews, and their conclusions. The better value in each row is highlighted.
In brief: Based on review measurements: Efficiency: 120 W 10 A desktop power supply (85.5 % vs. 81); Temperature rise: PTA-120W-12V (92 °C vs. 135).
Model 120 W 10 A desktop power supply 2026 Read review → PTA-120W-12V 2025 Read review → Voltage, V 12 12 Power, W 120 120 Efficiency, % 85.5 81 Temperature rise, °C 135 92 Review conclusion Not recommended With reservations
Only in one review: Current 10 A (120 W 10 A desktop power supply); In test 60 W (120 W 10 A desktop power supply); Ripple 40 mV (PTA-120W-12V).
120 W 10 A desktop power supply: Neatly assembled, but actual power is only about 60 W instead of 120 W, and it overheats at 6 A.
PTA-120W-12V: A budget PSU with good high-frequency ripple and power headroom, but noticeable low-frequency ripple.
Figures were taken from the review text and checked against the quoted passages. Measurement conditions differ between reviews, so read the reviews yourself before buying. Prices at the time of review.
