Enermax PlatiGemini 1200W PSU Review (ATX 3.1 and ATX 12VO)

There is no doubt in my mind that the Enermax PlatiGemini 1200 is an excellent power supply with a very impressive and unique design implementation. Enermax's cooperation with RSY has yielded a power supply right at the top of the chain.

Technically this is a very capable design in a variety of areas. Noise suppression scores well, as does load regulation with only some droop showing via the +3.3V rail. Cross loading didn't cause any major issues for the power supply, and noise levels are quite low until the upper end of power delivery after 1,000 Watts demand.

Efficiency of the unit is class leading, hitting over 94% between 40% and 60% load demand. Cable quality rates very highly, as does the build quality of the power supply itself. The fully modular design will tick boxes for system builders wanting the cleanest system build possible.

My only concern would be an unusually high triggering point for the OCP protection elements of the design. I didn't push the unit all the way to a breaking point, but at 1,750 Watts the temperatures were rising and OCP still hadn't kicked in. This could be rectified with some minor adjustments.

Another great feature of this particular supply is the diminutive physical depth of 150mm – one of the smallest 1200W power supplies on the market. This means that this unit will fit into a wider variety of chassis designs than many competing units in a similar power sector.

The Enermax PlatiGemini 1200W is priced around £225 in the United Kingdom, although availability right now is patchy at best. Enermax always send us Amazon links for these reviews, but right now the Amazon link for this product (HERE) is showing ‘currently not available'. We asked Enermax about this and they said the first batch of supplies have already sold out, and they expect new stock to land in May. USA availability seems quite good right now, priced at around $250.
