I'm going to be upgrading my GTX 660 at some point, and I think it's time I finally go all the way with getting a powerful GPU this gen.

However, the required wattage for the GPU (Which is 500) bothers me a little bit. Currently I have a Corsair TX650w PSU, which, btw, is around 4-5 years old, and has held up well with my constant upgrades so far.

I don't plan to overclock or SLI in the future until I get a better PSU, but I'm just asking: Will a single GTX980 (without OCing) be able to run on this PSU? These are my specs:

MOBO: ASUS Sabertooth 990FX R 2.0
GPU: EVGA GTX 660 3GB Edition
CPU: AMD FX 6350 6 Core 3.9GHz
PSU: Corsair TX650w
RAM: 8x2(16) GB Team Elite 1600mHz Dual Channel

Should be fine. Most of those ratings are inflated a bit.

GTX660 is rated at 140W stock, GTX970 is rated at 165W, GTX980 is rated at 185W. So not too much of an increase. Just need to make sure you have a pair of 6-pin PCIe connectors.

My PSU comes with only 1 6-pin, unfortunately. Most cards will come with an adapter to connect two psu cables into a 6-pin, right? If I recall, anyway.

Yeah, but you shouldn't use them. TX650W from that era doesn't have the best reputation.

Why wouldn't it? The thing lasted for 4-5 years, and it was used previously to power a EVGA GTX 560 Ti. What do I have to fear?

Are you sure? Isn't the TX range the non modular version of the original HX series?

Sorry, I read that as thermaltake TX2, my brain is playing tricks on me.

TX650W should be fine, it is a tier 2 supply. (I still wouldn't use an adapter with it)

Why wouldn't I use an adapter with it? It's not going to catch on fire or something, is it?

I'm still using adapters on my 660's just like I did with the 560's and it's the same PSU.
