OCZ fatal1ty 550w

post #1 of 8
Thread Starter 
It says its a 550watt psu. But it has 2 x 12V rails with 25A on each rail, doesnt that mean that its 600 watt?

theres also another 25A on both the 5v and 3.3v rails meaning another 150W of power.

Doesnt that effectively make it a 750W power supply?



Any ideas?

Isnt the wattage determined by Volts * Amps, which would then mean its 600W on the 12v rails (both combined).

and their math skills are pretty bad, according to that image, 450 + 150 is 550.

The Amperage numbers given are for what's known as OCP Set Points (OCP = Over Current Protection.)

In the case of something on your motherboard (or another part) going bad, that 25 Amp limit causes the PSU to go into a protective shut down state incase something tries to draw to much power at once.

Your unit can supply it's labeled wattage just fine though.

The Label is showing what the max amount of power that can be delivered is.

550w is the number that the PSU will be able to output 24/7

Yes, the 12v Amperage on your unit is rather low for a 550w for that matter.

If you were to go SLi with those units, you'd want to look for a unit that can output ~500w on the 12v rail continuously.
