So my PC, 2 years old has an ATX-500 500 W power supply and a GeForce 9500GT graphics card in a PCI express x 16 Gen 2 slot.

What nvidia card would you recommend to improve gaming experience up to around £100 ?

Currently it runs Guild Wars 2 OK although not brilliantly

Thanks !

Thanks for that link ! It's a PCI 3.0 card but I understand that's compatible with PCI 2.0 ?!

Yes it should be.

That's a great comparison chart !

Wondering if fact that my PC is a Phenom Six Core 1055 (?! ) makes an AMD card any better bet ?

No not really, if you are a fan of AMD's "Fusion" software then you will need an AMD card.

Just opened up my case and I can't see a 6 pin power lead that the 550TI needs, my current card doesn't have any extra power input .

Hmm is this an issue?

It raises concerns....although you may be alright with adapters, i prefer not to use them though.....

What is the make and model of your PSU?

Depends, how old is your PSU and does it have any unused Molex's?

PSU is about 2 years old, it's an ATX-500 500 W

It does seem to have 2 spare 4 pin connectors /plugs ( with red 2 blacks and yellow wires in )

These are tucked away at the top of my case and I think I'd need an adapter and some kind of 6 pin extender !!

That will most likely be bundled in with the card.

If this is the power supply you have then you need to think about replacing it immediately. Even though it's listed at 500W it's really a 300W PSU, based on providing 22A on the 12V rail.

I don't know anything about the build quality of that unit, but given its price I wouldn't assume it's very high. Keep in mind that if that power supply fails it could take out your entire system.

Yep that seems to be it - it is rated at 22A on the 12V rail

What would be a reasonable replacement ? This is getting more complicated !!

I looked at the PSUs offered by Scan and TBH I'm not familiar with all of them. The one that seems the best option is:

XFX P1-450S-U2B9 Pro Series Core Edition 450W Power Supply (PSU)

It's OOS right now, but it looks like they were expecting a shipment on Thursday so it could be available next week. Maplin does have that model in stock but it's a bit more expensive.

One of my motherboard power connectors is a 4 pin square thing . Is that a P4 ??

The board picture in my manual has code letters A880G+

That square 4 pin is just extra power. Many modern motherboards have an 8-pin aux power connection. Good power supplies (like the one I linked above) come with a 4+4 pin power connector so it can be used with either type. You'll just have to look carefully at the pattern of round and square pins to figure out which half of the connector to use with your motherboard.

The 880G on your motherboard probably refers to the chipset that it uses.

Thanks everyone for advice and help - mulling over my options now !! Learned a lot about connectors and so on that I was n't aware of before :)

Can't select a best answer as I asked 2 questions.
Have successfully installed a GTX 550i and a modular 500W power supply .
Poking around inside also helped me discover various leads that the local PC shop I bought it from had not finished properly , like DVD drive lead half hanging out and a broken wire on the USB connectors grrr . Thanks again all for excellent advice
