Practical testing …
We tested the ASRock Taichi TC-1300T in the following system:
| Component | Model |
| Mainboard | ASRock B650 Steel Legend WiFi |
| CPU | AMD Ryzen 7 7700 |
| Graphics card | KFA2 Nvidia GTX 1070 |
| RAM | Kingston Fury 2×16 GB DDR5 6000 |
| SSD | Samsung 850 Evo 500 GB |
| Case | Kolink Observatory Lite Mesh |
The installation of the ASRock Taichi TC-1300T went smoothly in the test and corresponds to the standard of modern ATX power supplies. With a depth of 180 mm, the power supply is slightly longer than simple models, but still fits easily into all standard mid- and full-tower cases with a corresponding power supply compartment. It is important to check the available space in the case before installation, especially for compact builds or if additional cables are to be hidden under the power supply unit.
The fully modular design makes installation much easier: only the cables that are actually required need to be connected, which not only speeds up installation but also ensures tidy cable management. The plug connections on the power supply unit are clearly labeled, snap in cleanly and have a very high-quality appearance overall. The supplied cables are long enough to allow clean routing behind the mainboard tray, even in larger cases. In the test, the plugs were firmly seated in the connections of the mainboard and graphics card and could be plugged in without excessive force.
The power switch and the switch for the semi-passive mode are easily accessible at the rear of the power supply unit. If you want to switch between operating modes frequently, you can do this easily even after installation, as long as the rear is not covered.
Overall, the installation was quick and without any special features. The TC-1300T proved to be compatible with all common motherboard and GPU standards and left a consistently stable and well thought-out impression.
No noise can be heard from the power supply when it is switched on, as the fan does not start up in zero-fan mode. The power supply is therefore operated passively as long as the temperature does not exceed a certain threshold. Even under load, the noise level of the fan remained pleasantly low. The fan curve is well tuned and there was no annoying spinning up.
Let us now turn our attention to the voltages of the power supply unit. A Uni-T Ut71C was used to measure the voltage and a Novkit PM04DE for the power.
Idle:
12V: 12.02V
5V: 5.03V
3.3V: 3.34V
Power: 120W
Under load, the voltage behaves as follows:
Load:
12V: 11.73V
5V: 5.01V
3.3V: 3.30V
Power: 380W
The measured voltages are always close to the specified voltages, which is due to the high-quality components. There is only one value that stands out. Under load, the voltage on the 12 volt rail is too low at 11.730V. According to the ATX specification (including ATX 2.52 and ATX 3.0/3.1), the 12V rail may deviate from the set value by a maximum of ±5% under load. The tolerance range is therefore 11.40 V to 12.60 V, within which our measured value lies. It should also be noted that the voltage remains constant under load.
Now we come to the conclusion.
