I currently have a GTX 760 and I am going to buy a GTX 980 soon. However, I am not going to get rid of my 760, I am going to have both in my computer. I currently use a 600w power supply. Is this enough to support the two cards?

--EDIT--

I am also getting an i7 quad core processor. I am not sure if processors rely on the power supply or not but will a 600w power supply be able to support these 3 things?

Giving this some extra thought... You clearly couldn't SLI these two cards. I'm assuming that the GTX 980 will be your main gaming card and the 760, your physx card. I've never had such a setup, but I'm wondering if running it as only a physx card will limit how much power the card pulls. For example, I seriously doubt simply having the two cards in your system will overload your PSU. The 980 will run at 100%, and even then wouldn't reach TDP unless you were benchmarking.

To be clear, I personally would upgrade my PSU in your circumstance, but I'm just throwing information your way, so you can make your own choice. I seriously doubt the recommendations were developed with your proposed setup in mind. Please let us know what your...

The big question that hasn't been asked is WHAT PSU you have. Because there's a world of difference between what you can run on a high quality PSU and a cheap piece of trash 250W unit that been falsely advertised as a "600W" model (there are plenty of those on the market).

That's question 1: Made and model of PSU please

Question 2: are you sure you want to keep the 760 in there? As rcald says, you can't SLI them and PhysX really doesn't have that big an impact on modern high end cards like the 980. You'd be sucking power and restricting airflow to the 980 for very minimal gain.

No worries and welcome to the forums.

If you're not 100% about the best upgrade option, why not post your full build, and what you're planning on upgrading? You can do that here or alternatively start a new thread. There's a very good chance you'll get some solid advice that could save you bunch of cash, or get you a better outcome for the same budget. Your call of course, but it might be worth taking the extra time to do that.

I shamefully bought a pre-built PC and just threw a new power supply and graphics card in over the years. At the time of getting it I didn't have much money to spend and it was pretty much an emergency buy. I will have to dig really deep to find the full specs but I'll make an attempt.

Don't worry about wonky specs or a pre-built PC. That's all the more reason to post your build because there's likely some real imbalance in the build (e.g. really strong CPU but weak GPU) which can be easily fixed without necessarily a large budget.

Here's an easy way to get PC specs: http://www.wikihow.com/Check-Computer-Specifications

Unless you have email receipts or records, you will have to pop your case open to get the PSU make and model and that's important for upgrade options, so do that one.

I did some looking around and it's a Thermaltake TR2 600W Power supply. Not sure if that's considered quality.

There are a bunch of different TR2 models, there should be some numbers afterwards to help us determine which is which. Some of them are okay, and some are pretty trash.

Given you're about to fork out big money for a GTX 980, why not either take a little time to figure out the exact PSU model, or just replace it with something decent. You don't want to risk an expensive video card like that by *hoping* your PSU will do its job.
