Some people paint funny logos on their cars.
Well, they had to feed all them cats!
Seriously though, I couldn't care less if someone wants to use a nuclear
power plant to power their PC.
If they can afford it and it's what they want, then it's no ones business.
The OP never asked if he needed a 600w PSU, just which others thought was
best.
I agree, if people want to get a 600 W power supply, they should
go for it. After all, they can't use more power than they use --
meaning, regardless of the rating of the PS, the computer is going
to draw the same amount of power. Having too big a power supply is
like having a V-10 engine and driving around the city at 30 MPH.
I'm wondering when the power supply of a computer will start to
overload a house circuit (when maxed that is). The average circuit
is fused for 1500 W. Seems sort of funny to me if we get to the
point when you can't plug in your toaster and computer at the same
time, or you'll blow a fuse.
