Antec High Current Gamer HCG-520M 520W Power Supply Review

Testing results (Regulation & Ripple)

Antec definitely improved the base
Seasonic design as the HCG-520M now delivers exceptional filtering, with the
maximum recorded voltage ripple barely hitting 22mV on the 12V line, nearly 6
times lower than what the design guides dictate as the operational limit. On
the other hand however, the voltage regulation circuit could use an upgrade.
Even though the 12V line is tightly regulated, a difference of over 4.5%
between 20% and maximum load occurs on both of the minor voltage lines, nearing
the acceptable limit of 5%.
