I have to choose between OCZ PowerStream 520w (with green fan) and Chieftec GPS550 550w AB-A, what is your opinion? Both are some 75eur here.
Chieftec: max out - 550w; +5V - 26A; +3.3V - 28A; +12V1 - 18A; +12V2 - 18A; +12V3 - 18A; -12V - 0.5A; +5Vsb - 2A; PFC - Active; 1x12cm fan
OCZ: max out - 520w (620w for 60sec); +5V - 40A; +3.3V - 28A; +12V - 33A; -12V - 0.5A; -5V - 0.5A; +5Vsb - 2A; PFC - Active; 2x8cm fan
OCZ have only one 12V reil but have adjustable volts, what now? Which one and why? Please explain to me, thanks.
The OCZ is proven a better PSU then a Chieftec PSU (they should just stick to cases). Are you only planning on powering the GPU in your rig now? The OCZ should be enough also Active PFC will lower that electrical bill on the rig as it auto adjust the volts depending on what you are using.
EDIT: I thought Active PFC was a requirment overseas?

Here is what happens, we do have passive pfc psu, like better models are active, you know what I mean, now I bought Chieftec, cause non OCZ remain in shops, wont be here for couple of weeks and my only choise was GPS 550w. It looks good, I can't even hear it and it is cold on touch, realy. I only hope it is good choise and it is made by Delta.
