The ADATA XPG Cybercore 1300W PSU Review: Advanced From the Startby E. Fylladitakis on March 10, 2022 8:00 AM EST
Cold Test Results (~22°C Ambient)
For the testing of PSUs, we are using high precision electronic loads with a maximum power draw of 2700 Watts, a Rigol DS5042M 40 MHz oscilloscope, an Extech 380803 power analyzer, two high precision UNI-T UT-325 digital thermometers, an Extech HD600 SPL meter, a self-designed hotbox and various other bits and parts. For a thorough explanation of our testing methodology and more details on our equipment, please refer to our How We Test PSUs - 2014 Pipeline post.
Most PSUs only bother to meet the certification requirements for a 115 VAC input, which is sufficient for overall certification regardless whether they meet the requirements for 230 VAC as well. This is not the case for the Cybercore 1300W, as XPG's PSU is capable of reaching 80Plus Platinum efficiency levels regardless of the input voltage. It has an average nominal load range (20% to 100% of the unit's capacity) efficiency of 93.3% when powered from a 230 VAC source, which drops down to 91.8% when powered from an 115 VAC source.
As promised by XPG, the fan of the Cybercore PSU doesn't even start until the load on the PSU exceeds 30%. Due to its very high efficiency, the internal temperatures of the PSU remains reasonably low even with the fan turned off. Once the fan starts, it will be only marginally audible at first, despite its dual ball-bearing engine. When the load is higher than 800 Watts, the fan’s speed will increase exponentially and will eventually reach its maximum possible speed. The end result is that the Cybercore PSU will get loud when fully loaded, but not unexpectedly so for a compact PSU with that high an output.
