Power:
The majority of the Enermax Infiniti’s 720W of power is of course delivered through the +12V rails which can delivery up to 672W of power in total. This is done through only 3 separate +12V rails which can deliver a massive 28/28/30 Amps down each one respectively. This is much higher than the latest official ATX (ATX12V and EPS12V) standards which state that if the 12V rails produce more than 18 Amps they must be split, however having more power down each rail allows more devices to be run on each rail without threat of being underpowered, so it’ll be great for SLI systems and systems with heaps of drives.
With the Enermax Infiniti, each +12V rail handles the following tasks:
- +12V1 – Drives + Video Card (GPU)
- +12V2 – Drives + Video Card (GPU) + (4+4)Pin Motherboard Power
- +12V3 – Main Motherboard Power + (6+2)Pin Video Card (GPU)
In operation the Enermax Infiniti showed very stable voltages across the board, we recorded the following voltages with our multimeter (not from motherboard sensor) at idle.
- +3.3V -> 3.31V
- +5V -> 5.07V
- +12V1 -> 12.14V
- +12V2 -> 12.15V
- +12V3 -> 12.15V
- +12V4 -> 12.13V
These are reading at idle, we tested the Enermax Infiniti under load (our test system running 3DMark06) and we recorded a maximum difference of around 0.03V increase across all the 12V rails, so voltage stability will not be a problem with these power supplies.
The Enermax Infiniti makes use of Universal Power Input, so any AC voltage around the world from 100-240V is accepted, and there’s no risk of forgetting to switch to the correct voltage and having something go pop, as there is no switch to forget, it’s all automatic. Active Power Factor Correction (PFC) is of course included as standard along with protection for almost every kind of overload you could think of (Voltage (over/under), Load, Temperature, Short Circuit) so your components and the power supply itself will stay nice and safe.
