Motherboard / PSU confusion

This is a very noob question but bear with me. I'm planning to buy a graphics card for my PC to replace the intergrated "chipset". It's probably going to be a Radeon HD 6570. Since that has a requirement of 400W of power I need to replace my 320W PSU. This raises some questions about connectivity. This is the model I've been looking at: http://products.xfxforce.com/en-gb/Power_Supply/Pro_Series_450W_PSU/P1-450S-X2B9

It's connections are listed as
1 x 20+4-pin ATX
1 x 4+4-pin ATX 12V/EPS 12V
1 x 6+2-pin PCIe
6 x 15-pin SATA
3 x 4-pin molex
1 x 4-pin FDD

My current PSU is connected to the motherboard only via 3 separate connectors, of which I've drawn an artistic rendition:

The circles represent "holes" on the connector. The crossed over circle means there is a hole, but no wire goes through it, thus an empty hole.

The graphics card I'm buying is to be connected to the PSU via a "six pin" connector, which I suppose is similar to the one pictured left. More info about the card here:

This brings me to the question, will the PSU have the proper connectors for both the motherboard and the graphics card? THANKS for your time.

The ATX 2.x standards lays out how the connectors on the motherboard and and any add in cards are connected. PSU's follow the same ATX 2.x standards. Normally, any PSU will have too many connectors and you will have spare, unused cables. Don't sweat it.

The problem is that I don't know what these connectors look like and where they should be plugged (and if my mobo actually has places for them). I'd post a photo of the mobo but I'd need to install some software first and I don't know where the CD is, lol. Please say if you need more information.
FOr reference here's my mobo specs according to Speccy:
Manufacturer Hewlett-Packard
Model 3647h (XU1 PROCESSOR)
Chipset Vendor Intel
Chipset Model Q45/Q43
Chipset Revision 03
Southbridge Vendor Intel
Southbridge Model 82801JB (ICH10)
Southbridge Revision 02

The main reason why I worry about this is because my PC is quite old and it is a somewhat "obscure" model (HP dc8000), so I just want to double check everything..


Bought the PC second hand, no manual included sorry

Google the mobo manual. You can look at the motherboard and the model number will be printed in big, bright, bold numbers and letters.

24-pin? Does it look like this:

There's not a slot like this on the motherboard. Does that mean the PSU is incompatible?

That seems likely... Thanks for the help anyway. Might be best to buy a new PC altogether.
