AC-DC PSU vs PSU with DC-DC Converter(+5V USB/PS2)
Posted: 27 Dec 2022, 12:38
Greetings
In terms of mouse/keyboard lag, I was wondering would it matter if old AC-DC PSU with three separate rails for +3.3V/+5V/+12V be paired and tested against new PSU with single 12V rail and DC-DC Converter that converts +12V to +3.3V/+5V? I'm not sure how DC-DC Converter works in modern ATX PSU's, but USB mice and PS2 keyboard are both on +5V and on older AC-DC PSU's they had their native power rail. I wonder does it affect USB/PS2 responsiveness and Voltage stability. Could anybody elaborate?
