I'm looking at buying an EVGA GeForce GTX 760 graphics card. At Newegg the power requirements are listed as "500 watt or greater power supply with a minimum of 30 amps on the +12 volt rail." My power supply is 550 watts but I'm unsure whether the amperage is sufficient. Here are the specs:
• ATX12V V2.2
• Modular
• 80 PLUS Certified
• 100 - 240 V 47 - 63 Hz
• +3.3V@28A, +5V@26A, +12V1@22A, +12V2@22A, +12V3@25A, -12V@0.5A, +5VSB@2.5A

(It's this one... http://www.newegg.com/Product/Product.aspx?Item=N82E16817371016)

I see each 12v line is less than 30 amps. Do these need to be over 30 to work with this card, or should I be ok without a new power supply? Any input is appreciated!

Nah, you don't need 30+ amps on each 12V rail, it's the combined rating that matters most.

The 12V rails are limited to 384W combined, which means the limit is 32A. So the power supply is sufficient for a GTX 760, even going by the official requirements (which can be exaggerated to provide a safety margin for low-quality power supplies).

Of course, the rest of your system does matter too. But it should be fine with most normal systems.
