Will this video card run on a 305 watt power supply?

I have a Dell Dimension E510 and I have heard that you can't install a new power suplly so I was wondering if the radeon hd 3650 512mb will work, if not can u please suggest a decent video card that will work.|||Not without installing a bigger PSU and it is possible to do it in a Dell, just check these official pages from the company:

How much power is necessary for PC systems ?



For your reference, following are details that illustrates approximately how much wattage you will need to run various common components in a PC system ( the components are on the left and the wattage required on the right):



The Motherboard: 15-30

Midrange to high-end CPU: 40-100

RAM: about 7 per 128MB

PCI add-in card: 5

High-End graphics board: 60-100

IDE/SATA hard drive: 10-30

Optical CD/DVD drive: 10-25



So let's calculate a system with a powerful motherboard, a (High-end) CPU, 4 Gigs of RAM, 3 PCI cards (including the 2 (high-end) graphic cards), 2 hard drives and 2 optical drives.



That would be 30+100+224(128MB X 8 X 4 = 4Gigs @ 7 per 128MB)+15(3 X 5)+200(2 X 100)+60(2 X 30)+50(2 X 25) = 679



So compare your computer specs with the list and do your own math, you will then know what PSU you should get.



NOTE: Leave yourself a bit of slack in your calculation for future hardware - Example: As calculated above, I would consider a PSU of at least 800 Watts and get up to 850 Watts if the price difference is slight.





Hope this helps you





Also, go for good build not just cheap price, compare PSUs on cost AND quality.|||most likely no, but i don't see why you wouldn't be able top replace the PSU.|||I don't see why you couldn't install a new power supply. They all use the ATX form factor.|||I'm sure that you can change your PSU. Go for a ATI 4830 or 4850.
