Is it safe to upgrade my power supply on my computer?

It's safe, your hardware only pulls as much power as it needa from the power supply. It wont overload anything, if that's what you're worried about.

Yes, that is possible.  Just make sure they are meant to sit beside eachother--they're usually idiot-proof.  The power supply I bought for my system had that setup, so I plugged the 20 pin and 4 pin in next to each other.  I have yet to fry anything in my computer.  With over $4k in parts, you can trust me; I would know.  :)

Sure you can! Just make sure you know your motherboard's socket number so you don't get one that doesn't fit.

You will need to open the case if it is not written on the back of the PSU.  That information is not shared to the computer.  You can check on the manufacturers site but, since Dell is a multi-vendor supplier, your computer and someone else's computer of the same name will not necessarily have the same power supply.  You will not need to do any serious dissembling of your case in order to read the sticker that states what it is.  Just remove the side panel or open the clam shell and it should be visible.  If you have trouble reading it all but can get the product ID number then you can search for its specs online.\n\nMost power supplies are very similar in size (woot stanadards) but it could be an unusual size.  It will be written on the sticker along with what it is rated for.  If you are looking for a replacement or wondering if a system problem is related to your power supply you WILL need to look.  Power supplies are often the first piece of hardware to fail on a computer and adding additional hard drives, cd/dvd drives, memory, or a faster processor will increase the required available power.  Computer manufacturers usually use the bare minimum power supply they can.  You can pretty much pick out a good power supply by its rated wattage and it weight.  A good power supply will be heavier.\n\nSo the short answer is no.  If you have a specific problem related to the power supply post another question.\n\nHope this helps and GL :-)

Its impossible to tell how many watts the computer is consuming by a program, but there are ones out there that can tell you the voltage.  this is what you need to know.  as far as if you power supply is powerful enough, anything of 450 should be more than enough unless you have some kind of huge amazing rig setup.  Mine is 500 and Im powering 3 hard drives with it.

If your power button is bad then yes, you can probably take the button from the old one (if it is the same - not all are).  The old power supply may or may not be the same - you may have an AT supply in one and an ATX in the other.  If the power connectors look the same (the large ones that plug into the mobo) then yes, replace it.  You need not install it into the case first to see if it works, just connect it to the mobo, connect the hard drive and see if it powers up.

Yes it is perfectly safe, The device will only draw the current it requires. So as long as you are providing at least 300mA the device will operate without being damaged.

You should chage your power supply to at least 400W to be able to put a reasonable graphics card. There is no reason why you should stick on with the 108W ps.

If you had power issues then lagging would be the least of your problems. A switching power supply will shut down if overloaded. If you are concerned that your PC may be getting close to pushing the limits of the power supply, You can check the the amperage either on the AC or DC side with a clamp-on amp meter to determine the load the PC is drawing.

Doubtful. Your PC is most likely a 478 or even 423 socket. You will have to replace it with a like socketed chip and one that your BIOS understands. eBay a P4 2.4 same socket is probably the fastest you will get your BIOS to support, check with the motherboard manufacturer on CPU support since you did not give enough information here.

I think you meant WATTS versus volts. You will need to inspect your power supply for that information.\n You need to check out he following website, for more info on what you will truly need 250W sounds a bit low by today's standards - http://www.jscustompcs.com/power_supply/

Just be sure that you are not overloading the UPS. Check the rating on it!

if i were you i would NOT do it.Send it to a computer guy if you still wanna overclock it.

Bro, you may want to go big. Get a 650 watt power supply and you'll be set for a long time

yea forsure you can if you have an open pci expansion port.  here is one you could buy for your pc from amazon.  personally i would go to a local computer store and talk to the salesman to make sure you can use it and ask what would happen if it didn't work (return policy)).  and also read the package carefully.
