Power Supplies

XPG CYBERCORE II 1000W Platinum Power Supply Review

Transient Loads

These results measure the power supply from 0% load to 100% load on various rails to simulate a power spike from your system. Typically, we would like to see as small a spike as possible relative to the requested voltage. With modern GPUs being notorious for power spikes, this is becoming more relevant in modern PSU design.

The specifications for ATX 3.0 were released in February 2022. It includes the new 16-Pin 12vHPWR connector that can deliver up to 600 W to graphics cards. These incorporate data lines for components to negotiate power capabilities with the PSU so they do not draw more power than the PSU is capable of delivering. The specification also has more strict requirements for handling spikes, two times the nominal output for 100 microseconds.

0-100% +5VSB

PSU is left in standby mode and then loaded to deliver max output on the +5VSB.

0-100% 12V

The PSU is left in standby mode, and that receives the maximum 12v load.

Mains Power Off-100% 12V

The PSU is physically switched off using its rear power switch, the full 12v load is then applied, and then the PSU is physically switched on.

As a child still in my 30's (but not for long), I spend my day combining my love of music and movies with a life-long passion for gaming, from arcade classics and retro consoles to the latest high-end PC and console games. So it's no wonder I write about tech and test the latest hardware while I enjoy my hobbies!
