Hi all, got the gateway dx4840-03c computer from futureshop. Here's the link for it:

As you can see, it only comes with a 300w power supply. I beleive the motherboard is going to be ok for a long time yet seeing as how I can swap it for the i7-860 but is there a limit as to the amount of power I can replace it with? Can I got a 600w or 700w power supply without surging the motherboard and devices? I plan on replacing the video card in time as well possibly with a 5770. Thanks.

You can not put too much power in a computer, it will only take as much as it needs from the PSU.


BUT

Do not get a PSU from a chinaware brand.

Cosair is always a safe bet.

Why do you want to change your processor? You don't need it for gaming a i5 or even an i3 will fine for almost anything unless your doing a processor heavy task.

You wouldn't have any problems with switching the power supply at all, I don't believe there is any sort of limit that your thinking of.

My second computer is running a 6 year old motherboard with a 550w PSU and it has no problems.

I do use it for gaming. The first thing I want to do to it is replace the power supply to probably a 600w then put in a better video card like the 5770 or a GTX 460 even. CPU wise, the extent that I can go on that motherboard is the i7-860. Anything better than that, I'd have to get a new one that has the 1366 fitting. Currently it has the 1156. By the sounds of it though, the i5-650 that's currently in there should last me for a few years yet. Any harm in doubling the power supply from 300w to 600w?

No. The system will pull just what it needs from the PSU.

That PSU will be plugged in a wall outlet with a 15 - 20 amp circuit breaker. You don't see the house dumping 1.8 - 2.4 kwatts into your PSU, do you? :)

If you game go ahead and upgrade your graphics card *you will also need to upgrade your PSU*


CORSAIR CMPSU-650TX 650W would be a good PSU

Last time I checked the GTX 460 was a better bang for your buck then a 5770 *Make sure to get the 1gig version of the GTX 460*

ok thanks, 6gb of DDR3 ram and the i5-650 chip wouldn't bottleneck the gtx 460 would it?

If you were to put a watt meter on your computers power supply you would probably find that it is drawing less than 150w full load. People often over estimate the size of the power supply that is needed.

I have checked and my graphics card ALONE takes 150w and so does my i7 920
