Power Supplies

MSI MEG Ai1300P PCIE5 1300W 80 Plus 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.

Transients are very clean here, with the virtually instant transition for the 3.3v, a smooth ramp for the 5v, and while there was a tiny overshoot on the 12v, it was extremely small and quickly corrected out to the desired voltage, reflecting the range seen in the ripple and PFC we saw earlier.

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!
