Thermaltake Toughpower GF A3 850W PSU Review

Box & Bundle

The box provides good protection. At its face, we find a quarter-shot of the PSU and a series of badges describing the product’s main features. If you want more details, look at the backside.

All intake and exhaust grilles are punched into the PSU’s chassis. The fan’s grille is too restrictive, hindering optimal airflow. The PSU has compact dimensions that don’t allow for a fan larger than 120mm.


Modular Cables
Description Cable Count Connector Count (Total) Gauge In Cable Capacitors
ATX connector 20+4 pin (600mm) 1 1 18AWG No
4+4 pin EPS12V (650mm+150mm) 1 2 18AWG No
6+2 pin PCIe (500mm+150mm) 2 4 18AWG No
12+4 pin PCIe (600mm) (450W) 1 1 18-26AWG No
SATA (500mm+145mm+145mm+145mm) 2 8 18AWG No
4-pin Molex (500mm+150mm+150mm+150mm) 1 4 18AWG No
FDD Adapter (150mm) 1 1 22AWG No
AC Power Cord (1380mm) – C13 coupler 1 1 18AWG

There are enough connectors, but the two EPS connectors on the same cable, and with standard 18AWG gauges, can be dangerous if you use them both. These connectors should be installed on dedicated cables since they can deliver more power than 6+2 pin ones because they use four total power pins instead of the three that 6+2 pin connectors use.

Cable length is sufficient, although it would be better if the EPS cables were a bit longer, reaching or ideally exceeding 700mm. Lastly, the distance between all peripheral connectors is ideal, at 145 to 150mm.

  1. Hello! I am currently choosing between this model and MSI MAG A850GL PCIE5 850W. As far as I understood, they are pretty much similar in terms of performance. The price is the same as well. The only difference I spotted is the noise level. Am I right? Which one would you choose?
