power suply isnt too expensive and it could help a lotAndy20 wrote:Hmmm says the maximum power output shall not exceed 250 watts, that sucks! I basically need a new Power Supply and Graphics Card and I can't really afford both!! The joys of computers :bad-words:

I wouldn't want to break my new computer!I would suggest you should talk to the people you bought it from regarding your options, so that you don't void the warranty.Andy20 wrote:I'm not sure how a power supply is installed reallyGavNormandale wrote:power suply isnt too expensive and it could help a lotAndy20 wrote:Hmmm says the maximum power output shall not exceed 250 watts, that sucks!

True but I don't use ebay myself and the PC I bought is on a 'buy now pay later' thing where I buy now and pay back 500 within 6 months with no interest so it's pretty cool. It did come with a 20 inch widescreen monitor too.dean1986 wrote:500 quid seems a bit much. Picked up a great pc on ebay for 200 quid.

It most probably would but if you do decide to change the power supply the trick is to take note of how the old one was connected.Andy20 wrote:Yeah that's my worry John, I think if I fiddle with the graphics card and power supply it would no doubt void my warranty. Because if it then went wrong they would put it down to me changing things on it
Is it pretty straightfoward changing the power supply? I'm rubbish at the internal bits of computers.rich0984 wrote:It most probably would but if you do decide to change the power supply the trick is to take note of how the old one was connected.Andy20 wrote:Yeah that's my worry John, I think if I fiddle with the graphics card and power supply it would no doubt void my warranty.

it really is simple, like metioned make note of where every thing went, a few screws hold the unit in place, all wires are just plug and socketsAndy20 wrote:Is it pretty straightfoward changing the power supply?

. The power supply is going to be one big problem (and I thought the minimum these days should be 300watts but there you have it 
).
).. If I recall correctly you say you installed RAM before? That, and installing a new graphics card, are possibly the two most easy things you can do inside a computer .
). The motherboard shown is not yours but the layout is probably very similar. Parts I and E in that image connect directly from the power supply and are the only two that are directly connected to the motherboard . All the other cables you probably see within the case connect to your hard drives, dvd drives and case fans etc. (have a look under the 'power supplies tab' on that website if you want to understand more about the cables ). . The very first thing to do is make sure you have unplugged the cable from the existing power supply to the wall socket!. Then you would need to disconnect every cable that comes from the power supply (i.e cables to the mobo, hard drives, fans etc. Make sure you keep note of what needs to be connected afterwards). You dont need to touch cables that go to the motherboard from the hard drives etc, only the calbes that go to the power supply. Then, on the rear of the case there are probably 3 or 4 screws holding the power supply in place. Simply unscrew them, and the power supply will come out (Make sure you lay the case on the floor so it doesnt drop down!).. Simply place the new power supply where the old one used to be (make sure the fan on the power supply is facing downwards into the case, not the top) and screw it in place with the screws provided. If your lucky, on some prebuilt computers they may use retention 'clips' which simply hold the power supply in place. If so, simply click the psu into place (though I would still use the screws just in case for extra safety). Once done, you can connect all the cables up. Remember, the motherboard needs the 20+4 pin connector (I in the diagram) and two 4-pin connectors (E in the image) from the power supply, which should be labled on the cables. Just make sure you match the pins in the correct order (they should only go in one way). Then its a case of connecting all your hard drives up and the case fans as they where before, using molex connectors for the case fans and serial ATA (SATA) power connectors to the hard drives and dvd drives.
, but if you decide to buy a new power supply, might I suggest something like this? You can have a look around on that site for example but that PSU would easily handle all you have/all you require and comes highly recommended . .
I usually leave the power cable plugged in, but with the power switched off at the socket, when upgrading computers. That way the case is earthed any you can discharge yourself of any static by touching the case.lostandwild wrote: The very first thing to do is make sure you have unplugged the cable from the existing power supply to the wall socket!
I have decided that for the time being I am not going to upgrade the new computer, with christmas coming up I should save my money rather than spending £80-90 on myself!
