A buyed a Back UPS ES 550, but I cannot find a PSU which is compatible with it :S
Can you send me a short list of compatible products?
I need product names like this: "CHIEFTEC CTG-450-80P 450W BOX " not like this: "every PSU with passive PFC"! :S
I have already read the whole internet, but hadn't find anything yet...
