550w psu enough for system?

[shea300]

Hi , Im just at the tail end of upgrading my gpu from a GTX 650ti to a EVGA GTX 980 Superclocked ACX 2.0. I was wondering if my psu would be able to handle my current system specs.
CPU: Intel i7 4790 (stock)
GPU: GTX 980 SC ACX 2.0
MOBO: MSI z97 Gaming 5
Case: Zalman Z11 plus ( 5 fans)
2x HDDS
RAM: 2x4gb Gskill Ripjaws @1600mhz
550 psu ( Have no idea what the brand is , I'm assuming is fairly old , stole it from my old rig).
I know the minimum required for the card is a 500w psu , just wanting to know if its a safe gamble running that close to the minimum. Thanks Guys.

I would not risk it if it is an old PSU that you do not know the name of. Pick up an Evga 600b, just to be safe.

550W would be fine if it is a very good quality unit, but that is unlikely. Get at least a tier two unit from THIS list. And since you need to get a new unit, best to get a bit extra for future possibilities.

This is a better PSU, for less. B2's are better than B1 or G1.

Yup, great PSU at a better price.

Unfortunately they didn't have evgas in stock for like 5 days and I wasn't about to wait that long for a psu so instead I opted for the Corsair CX 750 , I only bought this because apparently it is built better than the lower CX psu's which are listed as tier 3 on your list , so I am hoping that my psu hopefully falls somewhere in between tier 3 and 2. Thanks for the help.
