동일 모델은 아니지만, 서버 전원을 뽑아보니.. 별다른건 없고 PCI-Ex 슬롯 같은걸로 몇개 핀이 없길래 의아해 했는데
12V 단일 전압을 공급함으로서 전류를 높게 가지지 않아도 되니
PCI-Ex 슬롯으로 여러개 선으로 전류를 병렬로 전송하는 것으로 보인다.
The R320 power supply subsystem consists of one non-redundant or up to two hot-plug AC-DC power supplies. The power supply provides +3.3V/5V/12V and +12Vaux for non-redundant design and provides 12V and 12Vaux for redundant design. There are several voltage regulators in the system to supply different voltage levels needed by different logic devices. The redundant power supplies are managed through a PMBus interface.
