Sony Computers

I am thinking about buying a Sony computer. The model is a VGC-RB35GY.
The problem is finding out the wattage of the power supply. The specs
aren't posted for this particular model, but the ones around it, RB34
and RB36, say they have a minumum of 305 watts. 110-240, 7 Amps.

Would this be a 350 W supply? I want to upgrade the video card to an ATI
9800xxx or nvidia 6800xxx. Can anyone here help? Anyone using this
model or a similar one?

I didn't even know Sony made computers!
Thanks!

Watts = VOLTS x Amps

110 x 7 Amps = 770 watt power supply

That's a lot for a little notebook.

Something is clearly wrong here.

Me thinks, the 7 amps refer to the low voltage side - perhaps 12 to
16v.

The figures are misleading however you look at it. You clearly cannot have 7
amps at both 110 and 240 volts. The 7 amps is probably the total current at
all the low voltage outputs i.e. at the secondary outputs of the
transformer. I would regard it as a nominal 300 watts power supply. :0))

16v x 7 amps = 112 watts


k12bubba needs to check the specs again?

• Power Requirements
Min. 305W 100-240V 7A (50/60Hz)

Cut and pasted from the specs on the Sony site. This is a desktop.

It has me puzzled.

Well, you may be right!
I just checked some PC power supplies from Enermax and they seem to be
in the same ballpark.

or
<http://www.enermax.com.tw/products_page.php?gon=242&Tid=1&Gid=18&Gid2=23>

Look at line 2 under Specifications.

Ok.. I think what's going on here is that we are looking at the minimum
power requirements coming out of the wall into the power supply. But, Min.
305W is weird given that 7 Amps at 100 Volt is 700 Watts... So which one is
the minimum?

The rated power supply wattage is for the DC voltage circuit.

My I offer a suggestion? Why a Sony?... I know they look stylishly cute,
but those little 300 Watt power supplies are just not enough for a modern
computer. Inside the box, all these off the shelf computers buy their parts
from the lowest bidders... and that includes Sony.

Can you find a custom builder to configure computer with the best parts for
the same amount of money? Even Fry's electronics will build your computer
to spec. for free if you buy the parts.

The outside of a Sony may look beautiful, but the inside of my custom is
really beautiful.. and that's what counts.

Here's a link where almost all is explained:-

http://computer.howstuffworks.com/power-supply1.htm

At the root of this is the fact that switching circuits are used to convert
mains frequency to a much higher frequency enabling a smaller lighter
transformer to be used. However, as a result of this high frequency the
transformer will have a much higher loss in the iron core and possibly a
higher magnetising current although I was not a transformer specialist and
am not certain of this last point (the magnetising current is the current
drawn which is independent of load and creates the magnetic flux around the
core). I hope this throws more light on the subject but if not then tough!!
