My specs are:

Gigabyte 2GB GTX 670
Intel i7 3770k
Noctua NH-D14
Lexa S Case (with 4 built in 120mm fans)
Gigabyte GA-Z77-D3H Motherboard
WD 1TB 7200 SATA 3 HDD
Sata DVD Drive

I used a 650W TX V2 corsair. The fuse blew, so I'm assuming it wasn't powerful enough for my machine.
Could anyone recommend me a certain brand/wattage PSU?

(I am buying from ebuyer.com) :)

Cheers!

Hmm cause my mum took it to PC world, and this guy (who has his own business and is a friend of mum - so diagnosis was free) said that I needed a more powerful PSU? o_O

I am sending it back to ebuyer today. Should I go for a 800W-850W just to be safe?

Arron.
 
I'm with bartholomew.
The TX650 v2 is plenty of power over and above what your rig requires.

I think the fuse might have blown in your PSU due to a power surge / power spike and the fuse blowing probably saved your more expensive hardware from damage.

Nvidia recommendation for a system like yours with a GTX 670 graphics card:

-> 500 W PSU and 2x 6pin PCI-e power connectors.

Hmmm, could you explain to me what a power surge/spike actually is?

I do believe you are correct, my components don't really pass even 550W, so 650W is more than enough.

Also, do you still recommend me buying the same PSU?

Hmmm, if I left my PSU and my mains on, and I unplugged my mains to psu lead. Then I plugged it back in, would that have caused a powr surge?

Yeah, that was my initial thought. The TX 650 V2 is a solid unit.
