Ok so ive got a Packard bell PC. it has a 250W PSU - I have just bought a 300W one to power a new graphics card. However it doesn't fit in the case so - Can i power the HDD and CD drive off the old 250W PSU and just use the new one for the Motherboard and connect it through a gap in the case - or would I have to run everything off the new one - and put all of the wires through the case? The new one won't fit in the place of the old one.

I mean does the motherboard control all the power quantities - or can i just leave the majority of components with their old PSU?

I know having a PSU on the desk isn't exactly safe - but what I mean is - can you run half the PC of a different PSU or do you have to connect the whole thing to one?
 
OK thanks for the info. The Graphics card says it requires a Min 300W Power Supply - the current PC one is 250W. I didn't wan't to take the old one out before it was broken just because, but I don't really need the combined power.

The problem is the PC wants a PSU 130 X 130 X60mm this is unstandardised and don't exist for sale anywhere at all - i haven't tried to fit the standard size one in the case but I don't think it will fit.

WHY DON'T PEOPLE MAKE EVERYTHING STANDARD???? - Oh Yes it because they wan't you to buy a new one rather than upgrade bits - i think this should be made illegal !!!
 
The PC is a Packard Bell imedia S3720 a.k.a. B2521UK

It has an nvidea integrated graphics memory and I wanted either the geforce210 or this Asus 1GB card. They say min 300W PSU. So I looked in the case and it has a 250W PSU.

So I thought to run a new graphics card I should change the PSU to a 355W one to be sure i had enough power

The current PSU is Hipro The one i got as a replacement was a 355W Jeantech PSU
- so is there really a high chance of damaging the entire system?

The PC has 250 currently but is it likely that the graphics card wouldn't need a new PSU - because i was told any dedicated card needs 300W min PSU
 
If you didn't have a high enough PSU in the system for the card and you plugged the card in anyway what would happen? would it crash the system?
 
My System has - 1 X hdd (don't know RPM) 1 X CD/DVD+ - RW drive, 3GB ram ddr2 - 9 in 1 memory card reader, 10/100/1000 internet port, intel cerelon E3300 and i will get an Asus ATWI 1GB card - what total wattage PSU do you think this would need will this need ? with the new card would it still run on the 250W PSU? All the nvidea 215mb graphics card say the system should have a min 300W - so I assumed that a gigabyte one would need the same or more? as its ATI - however is that correct?

I have since found out that the Asus card uses 25W - would this be spare with all the other components ? and would it put the system in danger trying it on the old 250W PSU for a while?

The thing is I have so limited funds if I lose the PC by overloading it or something I won't have the money for a new build for about 5 years - which is why I have such a low capability system as it is

Sorry my posts are a bit un-gramatical

Just done a quick recky on the PSU calculator with your items and this shows a recommended wattage of 212w, minimum 162w.

So you think I should just try adding the card? But what would happen if there wouldn't enough power, would it turn of or something more drastic happen - like fans stop and system burn out?
