How many watts does this build need?

[Redneckmilitia]

Hey guys, I would like to know how much wattage my gaming PC build is going to need. I currently have an Antec Earthwatts 500w PSU (stripped out of an old build) and I do not know if that will suffice for this system.

Motherboard: Asus Sabertooth 990FX R2.0

CPU: AMD FX 8350 8-core processor

GPU: Nvidia Geforce GTX 770

RAM: Corsair Vengeance Pro (2x 8GB sticks of RAM)

HDD: 1TB Western Digital Caviar Black HDD

The PSU you have its not enough for the system,you should have at least 600 W or above.

If it were new the antec would just about manage mate - its a 5 or 6 year old model though so I wouldn't risk it either.

Look at a 600w as above for some clear headroom.
