550W Enough?

[TekSeven]

Is An Antec 550W Power Supply Enough For My PC Or Do I Need More?
My PC Specs:

Intel Core i5-2500K Sandy Bridge 3.3GHz (3.7GHz Turbo Boost)
1 GB PNY GTX560 (Not Ti)
CORSAIR Vengeance 8GB (2 x 4GB)
ASUS P8Z68-V LE
COOLER MASTER Hyper 212

Is 550W Enough? Thanks

Should be fine, with some room to spare.
Although a Radeon HD 6850/70 would outperform that 560 for around the same price point.

Will This Video Card Outperform The 560?

Don't know why you linked to an HIS product. There is a reason why it only has 68 reviews vs. this.
SAPPHIRE Radeon HD 6870 1GB 256-bit GDDR5 $170
or if you like dual fans
XFX Double D Radeon HD 6870 1GB 256-bit GDDR5 $190

If you don't believe the 6870 beats the GTX 560, see here http://www.anandtech.com/bench/Product/540?vs=543
The GTX only reaches ahead in Nvidia biased games.
