ASROCK PRO-750B
ASROCK PRO-750B
The ASROCK PRO computer power supply powers the individual hardware components in your PC. This component transforms the alternating current from the wall socket into the direct current that the motherboard, processor, and graphics card need to function. The device delivers stable electrical power to all connected components and maintains stable operation of the entire system, even under variable loads. The input AC voltage ranges from 100 to 240V with a frequency of 50 to 60Hz for operation in various electrical grids. The internal systems efficiently distribute power to the individual branches, preventing computer instability during intensive work.

Choosing a power supply
When choosing a suitable PC power supply, the key parameter besides the format is its power output. This indicates the maximum number of watts the power supply can continuously provide to the components in the computer. It is advisable to use a web calculator to calculate the optimal power output based on your chosen components.
ATX 3.1 and PCIe 5.1 standard
The design corresponds to modern specifications required by modern hardware components. The power supply meets the requirements of the ATX 3.1 and PCIe 5.1 standards, enabling it to handle short-term spikes in power consumption. This ASROCK PRO computer power supply can handle a total power excursion of up to 200%. This means the system remains stable even during the sudden power demands of modern processors and graphics cards, which briefly require significantly more power than during normal operation.
12V-2x6 connector with colour indication
A native sixteen-pin cable is used to connect modern graphics cards. The manufacturer uses a special two-tone design for the Classic Green connectors. This allows users to visually verify that the cable is correctly and securely connected to the appropriate port. Correct connector seating prevents damage to expensive components due to poor contact. The green colouring clearly indicates full insertion and simplifies assembly, even for less experienced PC builders.
80 PLUS Bronze certified efficiency
The power supply offers efficient operation, which is confirmed by independent testing. The 80 PLUS Bronze certification signifies high efficiency at various load levels. Efficient energy conversion reduces the amount of waste heat and helps save on electricity costs. At a standard 50% load, it operates with high efficiency, which leads to less heating of the entire system and extends the lifespan of the surrounding hardware components inside the computer case.
Active cooling and low noise
An integrated fan takes care of heat dissipation from the internal parts. The active cooling adjusts the fan speed according to the current temperature and load. The low-noise fan maintains optimal operating temperatures for the internal components without creating unnecessary noise in the room. The special iCOOL MODE stops or slows down the fan at low loads, reducing noise to a low level. The airflow effectively cools key transformers and capacitors.
Safety circuits
The manufacturer prioritises protecting expensive hardware from damage. The power supply includes a complete set of protection circuits against overload, overheating, overvoltage, and short circuits. These systems automatically disconnect the power supply in case of abnormal values in the electrical grid. Specifically, it includes OCP, SCP, OVP, UVP, OTP, and OPP protections, which monitor current, voltage, and temperature. This protects the computer from unexpected fluctuations in the distribution network or in the event of a failure of one of the connected components.
Reliability and lifespan
The internal construction uses capacitors exclusively from Taiwanese suppliers. The mean time between failures is 100000 hours. The use of Taiwanese components extends the overall lifespan and power stability, even under continuous load. The flat, rigid cabling simplifies wire management inside the case and improves overall airflow.

80 Plus certification on the European market
The 80 Plus certification was created to objectively evaluate the efficiency of computer power supplies. This gives users a simple and clear way to compare different models. On the European market (where 230V is used), there are six levels of 80 Plus certification, each with set requirements for computer power supplies. Higher energy efficiency primarily means lower energy consumption.
| PC PSU load | Efficiency at 20% load | Efficiency at 50% load | Efficiency at 100% load |
|---|---|---|---|
| 80 PLUS | 82% | 85% | 82% |
| 80 PLUS Bronze | 85% | 88% | 85% |
| 80 PLUS Silver | 87% | 90% | 87% |
| 80 PLUS Gold | 90% | 92% | 89% |
| 80 PLUS Platinum | 92% | 94% | 90% |
