Will my PSU do the job?

[Octavarium]

I'm fairly new to building PC's so I wouldn't mind a quick check (so I don't destroy my components!!).

I have just bought a ASrock Dual Series 939 motherboard and a AMD 3800+ X2 Dual Core.

In the short term I will be using my current AGP graphics card until I can afford a new PCI-E one.

How can I tell if my current PSU (about 9 months old) will work with PCI-E?

Secondly, does the dual core processor/motherboard require any special kind of PSU (I think im OK power wise...)

Whats the easiest way to find out exactly what make/model the PSU is?

Hmmm, the PSU was fitted by a friend of mine at short notice when the old one blew so I'm not sure about the Make I think it might be 400W...

Might be easier to just buy a new PSU as the old one can be used in another PC I am making for my Dad.

Any suggestions?

Spec:
AMD 3800 X2
ASRock Dual Series 939
Radeon 9600pro AGP (Soon to be Radeon X850XT PCI-E)
Single DVD ReWriter Drive
120Gig IDE HD
2 or 3 PCI cards (Wireless LAN, Sound card etc)
