PS requirements

[GullyFoyle]

Yeah, another one of these...

I will be upgrading my video card and am wondering if I need to upgrase my power supply
Current Hardware:
Intel i5 3570
Asrock z77 extreme 4 MB
8 GB ddr3
Hard drives:
KIngston 64 GB SSD
Samsuing 1.5 TB
Seagate 2 GB HD
Toshiba DVD Writer
Antec True Power new 550 Watt PS

I currently have a mile 4.2 Ghx overclock on the processor
I am adding an eVGa GTX760 ("factory overclocked")video card (~170 Watt)

somewhere in a review of the video card they recommended 550 or higher if you overclock. SInce I have an <small> overclock, will it be an issue?

Your 550w should be, the TP New's are great PSU's. I'm running my overclocked/overvolted spec off a 500W PSU and have measured that when gaming, at most it draws 380w from the wall (350w from the PSU when you take 92% efficiency into account) with Vsync and triple buffering enabled. Your system should draw less than this so long as you use Vsync (d3doverrider can be downloaded to enable triple buffering in everything except OpenGL and x64 bit games to smooth out framerates).

The minimum PSU requirements usually take into account that not all PSU's actually output what they say on the side. Some of the really cheap ones just advertise the maximum output which they can only handle for a few milliseconds. The actual continuous output is sometimes around half this but you don't have to worry about that with your Antec PSU.

Should work great. Running the system in my sig off a 450W Corsair PSU.

One PCIe Graphics Card (single 6 pin OR one 6 pin + one 8 pin) should be perfectly fine with 550w PSU .. You'll need to upgrade ONLY if you decide to go SLI ..
