Solved how to upgrade an hp p6540d 250w

Specs: Windows 7, Pentium Dual Core E 6600
I want to upgrade my HP 6540 PC but am not sure if a higher W PSU will not harm my board and other peripherals since the original PSU installed is only 250W. I want to do this because I also want to install a graphics card to add up to the Intel G41 onboard GMA. Please give me advise. Thank you very much.

Consider how much your complete upgrade will cost you over the coming months and compare that cost to the price of purchasing or building a new system. You probably would find that there is not that much difference really. Consider starting over if the cost is close.

You can upgrade the power supply without worry. You could use a 1000Watt unit but if your combined draw is only 200Watts, that is all that will flow into your system. Practically, the 1000w watt unit would not be cost effective for you, but a 500Watt or 600Watt unit might make sense. It is important to purchase one with a single 12 volt rail and 80% efficiency rating, and to shop for your graphics card first to see the requirements as far as Wattage AND Amperage on the 12 volt rail.

Remember that if you upgrade your PS, Your MB, your GPU, you will end up adding to or replacing your RAM, and you still only have a Pentium E6600. Would you then think about upgrading that??? Probably! You really should consider a fresh build, something brand new, modern, and fast, that you would be happy with for a number of years rather than dumping more money into each month or so without ever really achieving that really fast system you are craving.
Look at the 2nd generation i-3 or better and a reasonable socket 1155 board (Gigabyte has some with nice features at a decent price range), DDR3 memory, etc..

You have to be a little bit crazy to keep you from going insane.

Thanks for the early reply Fingers, I appreciate it very much. Well I'm really new on these matters that's why I'm taking it slowly but surely. I'm Just planning at least a 600 or 500W since all I want is just to improve my graphics to play some games then to load images a bit faster. My Board's processor highest upgrade would be a quad core & RAM is a 2GB DD3 with 1 more slot vacant. My system is just 32 bit so if I add 1 more 2 GB RAM the est. memory would be 3.3GB only. Anyway my main concern is the PSU and graphics card. What would be the ideal and compatible PSU and graphics card if I upgrade for this kind of system? For your easy reference here's a Brief Description of my PC:

HP p6540D
Pentium E6600 (w) 3.06 Ghz. (65w)
1333 mhz front side bus
socket 775
Chipset: Intel G41 Express
Motherboard Name: H-IGI41-uATX
HP/Compaq motherboard name:Eton -GL6
Power Supply 250W
Memory 2GB max. allowed 4GB (2x2)
Speed supported pc310600mb/sec Type 240 pin DDR3 SDRAM
Hard Drive 320GB SATA 3G(3.0 GB/sec.), 7200 RPM

Your advise on upgrading at a higher end, for now I don't think I can cope with it due to some financial constraint also that's why I said I'm just making it slowly but surely. But rest assured that I am considering all your advises. Hope to hear from you again.
