Haven't built a PC in a while and getting somewhat paranoid over it.
Since my last big upgrade is about 3 years old (minor parts since then), planning to upgrade from a Dual Core, Nvidia 7950GT and wanted some advice on weather my PSU will be able to handle this;
Intel Core i5-2500 3.30GHz (Sandybridge) Socket LGA1155 Processor - Retail
Asus GeForce GTX 560Ti DCII/2DI/1GD5 DirectCU II 1024MB GDDR5 PCI-Express Graphics Card
Gigabyte GA-Z68X-UD3P Intel Z68 (REV B3) Socket 1155 DDR3 PCI-Express Motherboard
Corsair 8GB (2x4GB) DDR3 1333MHz XMS3 Memory Kit CL9 1.5V unbuffered [CMX8GX3M2A1333C9]
Salvaging my HDD's (3) and using them too (Hard drive prices are INSANE at the moment)..
currently i've a Hiper 550W PSU, do i need to upgrade? I don't really plan on OCing, hence no K after the i5.
Cheers in advance.
