Power requirement calculator

Don't know if there's a power requirement calculater on the forum somewhere already, but I came across this one today and thought it might be useful.

they're all meant to be rubbish and a waste of time.

Oh...

That's just the ones I've heard about thought, this one could be good, you never know

what do you need it for?

if you need to know if a psu if powerful enough just post the build specs here and someone will tell you within a few minutes

I need to know if 400W will be powerful enough for my new build (see details in my sig).

I am looking for a modular PSU with stable voltages and a reasonably "green" footprint, so it doesn't suck down enormous amounts of power unnecessarily.

Having read a few reviews for this thing, I am pretty impressed by it. Just need to know if 400W would enough to power my new build.

no it won't

you will need a 500w psu for that, preferably the corsair 520w or if on a budget the huntkey 550w

a PSU only takes as much power as it needs.

And PSUs are more efficient when they are not working close to their maximum output.

So a 1000W PSU will be more efficient that a 400W PSU if 380W are being used.

Righto, thanks guys.

Did you go for the Enermax in the end? As I would recommend them (Noisetaker range) or the Corsair HX520

I've settled for the Corsair HX520, because the Enermax SATA cables have 4-Pin Molex attached to them. This makes things a bit messy and IMHO defeats the purpose of a modular PSU.

So it's Corsair all the way.
