hi all! i'm building a gaming pc soon and wanted to know how much wattage i need for mild to moderate overclocking. i'm going with a slightly overclocked xfx 7870 ghz edition, intel core-i5 3570k, z77 motherboard and will be running an cooler master hyper 212+ cpu cooler. is 550w enough for my needs, or should i only get 600 and above? any input helps!

Here is Guru3D's power supply recommendation: Radeon HD 7870 - On your average system the cards require you to have a 550 Watt power supply unit as minimum and 700 Watt if you go with two cards in Crossfire mode.

If you are going to overclock the GPU or processor, then we do recommend you purchase something with some more stamina. http://www.guru3d.com/articles_pages/amd_radeon_hd_7850...

i'm looking at this:
Ultra Limited Edition 600W Power Supply, is ultra a decent brand? it's not 80+ rated but it does have a lifetime warrenty, after promo code and rebate it's $14.99 on tigerdirect.com worth it?

well, ive never heard of it, maybe its a tiger direct house brand, i dont order from them. and i would never trust a power supply $15 power supply. it will most likely blow out, and take some system parts with it.

the antec unit mentioned earlier is a great deal and will last you through future builds.
