In rebuilding my PC, I'm looking to get an ASRock B85 Pro4 Mobo. However, I've got a Corsair GS800 PSU and am unable to confirm via either manufacturer, whether my PSU is compatible with this Mobo. As neither company include a compatibility table in their specs, it seems like maybe any PSU will work with any Mobo, but that surely can't be the case can it?
Pretty much
Almost any psu will work with almost any mobo.
Thanx Rugnir. What confuses me is that I've also got an OCZ ZX Series 1250W PSU, and on the face of it they seem to offer different power specs. Once again with self build PC's, I'm straying into areas beyond my knowledge!
Is it the case that PSU's have monitors that allow them to provide the required power to any connected components? So the ZX1250 can provide up to 1250W, whereas the GS800 can provide up to 800W? What surprises me is the idea that PC's need such extremes of power! It would take a good half day's research to discover and add up all my current components wattage requirements, but a back of the dearest comrade packet guesstimate comes in at around 100 to 200 watts max. What sort of system could possibly require 1250W? Still somewhat confused, but reassured.
Sorry I was away so long >.<
People use high power psus because power supplies have an optimum efficiency at round about 50-70% load. also, with SLI and crossfire on high end cards, you can rack up to about 800-900 watts usage quickly.
as for how they do it, the components just draw more current and the voltage should stay at a fixed point, which changes the wattage.
current x voltage = watts
so the watts can change as the system want it.
