I am looking to upgrade my pc so i can play online fps with decent framerate. Ive narrowed it down to this card:

however i found some people saying that a 240W psu wont be enough for this card.

Do i also need to get a better psu for my PC?

240w is extremely close because you have to take away the cpu, hard drive, motherboard, optical drive (if you have one), etc. which you leaves you with a very tight amount for the video card.

I just looked up the Sapphire version of your card ( HD 7750), It has a system requirement of a 400watt PSU.

I would say that it needs at least 400 watt PSU.

No. first of all you will power up the board,CPU,HDD, FANS, and the additional GPU. The PSU will reach its thermal limit and the system will crash. i suggest that you buy at least 400 watts of PSU from seasonic, antec, cooler master, XFX or any known brand.

That psu will be fine for a hd 7750. I currently have the same psu with a hd 7770 (sort of a placeholder until later this year) and haven't had any problems with it at all.

One other thing. Im not 100% certain the 7750 is compatible with my motherboard. Here are the specs:
HP Compaq 6000 Pro SFF - Windows 7 Pro

Intel Core 2 Duo 8400 @ 3.0Ghz
2Gb DDR3 RAM
3048h HP mobo (according to cpu-z)
240W PSU (before I upgrade).

I' have one PCI x 16 slot but i think its 1.0 and I know the 7750 is 3.0.

Any help is welcome.

The PCI Express x 16 slot is backwards compatible. In other words the latest version of PCI Express x 16 is compatible with earlier versions.

So basically i just need to get a decent PSU thats above 400W right? Will a bronze certified PSU be fine for my needs? I just want a cheap and reliable one.

Yes, it will. The one I linked is a gold rated Seasonic 450 watt PSU, but it is only $75.
