FSP FlexGURU FSP250-50FGBBI(M)

FSP FlexGURU is a power supply unit of the smallest internal format Flex-ATX, which, by the way, was invented and first implemented by FSP. Only Pico-ATX is smaller than it, but it consists of two parts: an internal miniature module mounted directly on the 24-pin motherboard connector, and an external power supply unit, a la laptop charging.

And if Pico-ATX give out a maximum of 180 W of power, of which only 120 W goes through the main +12 V line, then FSP FlexGURU, including the updated Pro-series, start from honest 250 W and up to 500. Efficiency for the younger 250 The watts of the model are claimed to be 85%. This is not de jure confirmed by the 80 PLUS certificate, but given the impeccable reputation of FSP, its words can be trusted.

FSP FlexGURU, like all other Flex-ATX power supplies, can only be scolded for a noisy fan. A 4 cm impeller is used with a speed of 5000+ rpm and a volume of up to 45 dB. Fortunately, at least the bearing can withstand up to 100 thousand hours of operation. In comparison, the Pico-ATX is fanless and therefore silent.
