How many amps does the power supply have on its 12 volt rail or rails(multiple rails are treated a bit different.) and what else is in the system?
An example of a multiple rail power supply.

What else is in the system?
CPU
Motherboard
Number of hard drives drives
Fans
Other things in the system.
I would like to take this time to point out that the 300 watt Seasonic unit shown above has just as much power(288 / 12 = 24) as that "450" watt power supply.
What brand is that power supply also please.

I don't know the brand I bought it as a built system, I know only basics and I am picking stuff up along the way, I have 3 spare molex adapters from the psu and was just hoping a molex to 6 pin pci-e adapter would be fine but I read somewhere it could fry my card

You should be ok(the 7770 is a very power friendly card).
It is recommended that you do NOT overclock anything further without looking into a newer power supply.
What brand of power supply is it anyway? That makes a big difference sometimes.

I have no personal experience with CIT
Just remember when comparing it to the newer(modern power supplies give almost all the power to the 12 volt rail then use dc to dc to get the lower rails. This gives lots of 12 volt while still being able to have enough 5 and 3.3 power if it is needed) power supply, It has more in common with a 300-350 watt then a 450 watt power supply. So don't push it too hard and things should be ok.

Overclocking or adding more hard drives would be pushing the power supply harder.
If you are ever curious about computer power consumption, you can also get a power monitor/meter at the hardware store that plugs into the wall then the computer plugs into it. Remember that AC input is ALWAYS higher then computer DC output and new power supplies waste less power then older ones(I am betting yours falls into the older category).

The almost too cheap(for a 600+ watt unit) to be good scares me a bit to be honest.
Most 650 watt power supplies have at LEAST 2 pci-e(at least one is an 8 pin most times) power connectors.
What is even funnier is this "Micro ATX" power supply. Less power then a quality 300 watt AND it is SFX not mATX.
On a budget, this should work for you(it is not rated for higher temps like some more expensive units), if you can get a bit more, Corsair has some better units as does OCZ/Antec/FSP/Seasonic/Silverstone/ect
