The Battle of PSU and GPU !!

this week I decided to upgrade my GPU with the Sapphire Amd 7750 OC edition
( http://www.sapphiretech.com/presentation/product/?cid=1&gid=3&sgid=1159&lid=1&pid=1501&leg=0# )
and until the last minute,I assumed it was all simply plug and play since I knew my PC had a 450 W PSU installed but then I accidentally discovered that things were more complicated than they seem!! --> http://i.imgur.com/61dN3.jpg (psu specs)

Firstly the system requirements mentioned on sapphire's official website say that their 7750 requires a min. 400 W PSU but they don't say whether I need to connect it to the PSU via a 6 PIN pci cable or not.. because if it does need to be connected then I have a little problem...,my PSU doesn't has a 6 pin PCI .. it only has one Molex 4 pin connector --> http://i.imgur.com/jdbqN.jpg which seems to be shared by the DVD drive too --> http://i.imgur.com/CsaxQ.jpg

I even shabbily ran one of those standard PC power consumption tests,it said my PC uses 257 W out of 450....
So my question to you,is this PSU enough for the mentioned card??plz give me a green signal because if it isn't then I'll have to spend another 50₤ on the PSU :/

My general PC specs
AMD X2 Phenon,3.1 Ghz
1x4gb DDR3 RAM
SATA 7200 RPM 500 GB HDD
1x19" LCD Monitor
No additional coolers or nuclear reactors attached!!

    It will work. That card doesn't need any auxiliary power connectors from the power supply unit.
