I have a Dell Dimension 5150 and i am looking to upgrade my computer with a new graphics card and psu. I have found a graphics card you can see it here:http://www.amd.com/us/products/desktop/graphics/ati-radeon-hd-4000/hd-4850/Pages/ati-radeon-hd-4850-... it requires 450w (minimum) to run and my psu is only 305w. I was wondering if anyone knew of any PSUs that would fit my computer.
Also to add i live in Australia so it would be useful for the seller to not be charging allot for postage.
Also will this psu work in my pc?
You might consider a more efficient, newer card like the 7750, which wouldn't require a power supply update.
The 4850 is three generations behind and requires much more power per unit of performance.
It is best not to buy a cheap power supply if your goal is to upgrade your video card for gaming. The one you linked is definitely on the cheap side. Most likely your CPU does not meet the requirements for either of the games. The HD 7750 would meet the video card requirement and the only one that would probably work with your current power supply at this performance level. They do come in single slot versions if that is what you need. I would think that you could use a dual slot also, but I know there are concerns about the heatsink housing on this model. With your BTX case design, the fan will be facing towards the top of your tower so it should not interfere with any card that might be in the PCIe x1 slot right below it.
With the HD 4850s being so old now and in limited supply, I would think that you can get the HD 7750 for less if buying new which offers better performance. However, I would still be concerned about your CPU if you are running an old Pentium 4.
