# Power supply
Board has two supply rails.
`0.95` and `3.3` volt.
## `0.95` Core Voltage.
Voltage is made by a `Richtek RT8120A` Buck converter.
0.95V must be within 3%.
## `3.3` Voltage
Voltage is crated by a `TMI3244T` Buck converter.
3.3V must be within 4.5%.
Chip can deliver up to 4A and the sweetspot is at 1A.
So higher power SFP-modules should work.
