My System Specs

Default how much power do i need

Hey guys,
I was thinking of getting a new power supply for a future video card. I currently have a Thermaltake 500w power supply but i have been told 500w isn't enough for a high end video card. How much power do i need to run a single high end card such as a GTX 680 or a Radeon 7900 series card. I am looking for any power supply (no preferences) that can run the video card and the rest of my system.

System specs:
Intel Ivy Bridge core i5 3470, 8GB ripjawz x RAM, GigabyteB75M-D3H, Samsung 500gb and a Samsung DVD burner.

500w may be a little on the weak side of things. Especially if you plan to OC. My setup has been great with or without ant overclocking. My system is older and less efficient than yours. But I would still recommend a 750w PSU with as many amps as possible.

I would recommend this.

Can't go wrong with a Corsair 750W power supply either, and they tend to be a bit less expensive (or on sale more often)

With your setup a quality 650w will be perfect. Get a 650w antec, corsair, seasonic, or xfx.

You can run a 680 or 7900 on a Quality 500W unit. The IB takes very little power. However I would not Trust the Thermaltake unit to be up to the task.
Good High quality units would be:

Antec Earthwatts EA550 Platinum 550W 80PLUS Platinum 4X30A Active PFC 120MM DBB Fan Power Supply

Corsair Enthusiast Series TX550M 550W ATX Modular Power Supply Active PFC 120MM Fan 5 Year Warranty

Seasonic M12II 520W EPS12V 20/24PIN ATX PFC 80+ Bronze Modular Connectors 6PIN PCI-E 120MM Fan

XFX 650W PRO650W Core Edition Single Rail ATX 12V 53A 24PIN ATX Power Supply 80PLUS Bronze PSU

Any of those should suffice. Though if you have the cash , the Antec one is the best and newest of the bunch.

I had the XFX 650 Core and it was holding a GTX 460, a 9800GTX+ and a GTS 250 in the same time folding, plus a Phenom II 965 so it is a very capable PSU, Seasonic OEM.
