Ultra Products X-Finity ULT-XF600 (600W)
The ULT-XF600 is manufactured by Wintech and is based on the same components as the previous model. The difference between the two is mainly in the cooling system design. For some unclear reason the senior model is cooled with two coaxially mounted 80mm fans rather than with a single 120mm fan.
The steel case of the PSU looks matte in the snapshot but it is steel indeed.
Like the ULT-XF500, this power supply supports input voltages of 110V and 220V. The switch is placed in its traditional location here, next to the mains connector.
It’s easy to see the ULT-XF500 and ULT-XF600 are based on identical PCBs but differ in the ratings of the components (the high-voltage capacitors on the input of the senior model are 1500µF rather than 1000µF now, and the heatsinks are larger). One of the fans is smugly nestled in the gap between the PCB and the panel that was empty in the ULT-FX500; the engineers had to make the case a little longer to fit the second fan.
The load capacity of the PSU has increased according to its wattage. The allowable current on the +12V rail is 3A higher in comparison with the junior model, but the max load on the +5V and +3.3V rails hasn’t changed much.
