All available protections for consumer grade PSUs are utilized in this unit and the max operational temperature is 50°C. Unfortunately its price is on the high side, for an 800W PSU, but do not forget that the iPower Meter's cost isn't negligible.

There is only one +12V rail which can deliver almost the full power of the PSU, common for units that use DC-DC converters for the minor rails generation. The max combined power of 5V & 3.3V looks rather low at 120W, but you won't need more nowadays from these two rails.

Except the unjustified lack of a second EPS connector the unit has a sufficient number of connectors and all cables are long, so even in large cases you won't face the slightest problem. Also the distance among connectors is 150mm, the recommended length by ATX spec. All connectors use 18 AWG wires, which is the recommended wire gauge by ATX. Nevertheless we would like to see thicker 16 AWG wires on the 24 pin ATX, EPS and the PCIe connectors for less energy losses.

Since this PSU features a single +12V rail we do not have anything to comment about its power distribution.
