EXTERNAL TOUR

The exterior of the Corsair PSUs is not usual. The black/yellow (520) and black/red (620) color scheme is attractive.


Nothing out of the ordinary here.


No vents other than the fan intake and backside exhaust grill.

A single 120mm fan draws air into the power supply from below, blows it across the heatsinks, then out the low-impedance back grill. A wire grill protects the fan while providing a low resistance to the airflow.


Five connectors for SATA and ATA drive power connectors; two for PCIe 12V power.
(Do these connectors look familiar to you, by the way?)


The labels for the PSUs.

We know of course that Corsair is not the manufacturer, but the E307858 UL file number marked on the label does belong to Corsair. Opening the unit up should tell us who actually manufactures these PSUs.

OUTPUT CABLES


The main output cables are sleeved; the rest are black plastic insulated. No color coding here.
