Cooler Master GX1050 GOLD fully modular power supply with peace of mind, even when testing the RTX40 series graphics card burn-in, as it is designed for the new generation ATX 3.0

Table of Contents

ATX 3.0 new generation, with RTX40 series graphics cards, no worries about burn-in!

Following the release of the NVIDIA RTX40 series graphics card, the graphics card connector was changed to a 12VHPWR connector, and the specification was upgraded to ATX 3.0. This new specification improves the power supply’s ability to tolerate high power peaks. It allows for an instantaneous peak power consumption increase to 200% of the rated power, lasting for 100μs, particularly when under a load.

Cooler Master has launched its first ATX 3.0 power supply product, the GX1050 GOLD, which boasts a gold medal for its full modularization. The entire series has passed the 80PLUS gold medal certification, with a high conversion efficiency of 90%. Customers can choose from two wattage options: 1050W and 1250W. The power supply uses all Japanese electrolysis capacitors to provide high-quality power output, and its 12V power supply has a single-channel design that ensures a stable graphics card power supply, without any need to worry about the shunt problem.

The GX1050 GOLD power supply employs a 140mm FDB liquid dynamic bearing fan that operates quietly and has a long lifespan. The smart heat dissipation control system (STCM) ensures that the fan does not rotate under 40% of the load, resulting in zero noise. It operates safely in any environment. The security mechanism offers OCP, OVP, SCP, OPP, OTP, and Inrush Protection, giving players peace of mind. The power supply’s fully modular design, except for the 12VHPWR wiring, uses flat black wires that allow players to complete the line and maintain the case’s appearance inside. The warranty provides an extra-long 10-year service. Overall, the ATX 3.0 new generation Cooler Master GX1050 GOLD fully modular power supply offers excellent performance.

Test

The testing platform comprises an AMD Ryzen 9 7950X CPU, an MSI MEG CORELIQUID S280 cooler, an ASUS TUF GAMING B650-PLUS motherboard, and a Neo Forza DDR5-7200 32GB Kit running at DDR5-6400. It also includes a PNY GeForce RTX 4080 16GB XLR8 EPIC-X RGB graphics card and a WD Black 1TB NVMe SSD for storage. The power supply unit used is the Cooler Master GX1050 GOLD. The operating system installed is Windows 10 Professional 64 Bit.

The test time is 30 minutes in total, idle for 5 minutes -> burn-in for 20 minutes -> idle for 5 minutes.

**When using the OCCT test, the total power is about 686.03 watts**.

**The 3.3V performance standby voltage is 3.345V, and during testing, the voltage fluctuated between 3.33-3.345V. The average voltage was around 3.3375V, with a voltage drop of 0.22%.**

**The 5V performance standby voltage fluctuated between 4.9775-5.0225V, while during testing, the voltage remained stable at 4.9775V without any fluctuations.**

**The 12V performance standby voltage is 12.08V, and during testing, the voltage remained stable at 12.08V without any fluctuations.**

Summary

The Cooler Master GX1050 GOLD power supply boasts excellent performance, delivering a peak of around 686 watts while undergoing burn-in with an AMD Ryzen 9 7950X and NVIDIA RTX 4080 under pressure. The voltage drop for 3.3V was only 0.22%, while the 5V and 12V voltages remained stable throughout the burn-in process without any fluctuations. The fan-generated a bit of wind noise during testing, and the temperature of the shell was slightly higher than the room temperature. However, the power supply can accommodate numerous devices, and its cable connectors are more than sufficient, with cables long enough for most needs. The Cooler Master GX1050 GOLD fully modular power supply is ideal for power upgrades or gaming console users, and it comes with a 10-year warranty to put players’ minds at ease.
