Hello guys.
I have a corsair vs 650 watt psu and i am planning to buy g1 980 ti in future. Will my psu be enough to run it?
My configuration is-
I7 4790k
WD 1tb blue hdd
5 cooler master jetflo
Asus bd writer
Cooler master 212x
Asus maximus VII Ranger

I also noted that it need two 8 pin connectors but i have 6+8 pin connectors left. So for that i have to upgrade my psu or the 6 pin to 8 pin connector will work or there is other better way?
Thanks in advance.

Addendum:

Your power supply falls under tier 3 (description below). Technically you have enough wattage to run the card. I'd be cautious when overclocking on that tier of card though. If you decide to purchase a new power supply, consider upgrading to 850 or 1,000 watts if you might one day SLI or CF two Nvidia or AMD cards respectively. I have a personal preference for EVGA G2 power supplies.

Tier Three
Some Haswell compatible, some not (maybe unconfirmed). Still safe to use and stable, just lower quality components. Some capacitors maybe Japanese, but can include the Taiwanese capacitors. Not really ideal in serious overclocking or super-high load situations, such as a Bitcoin mining rig or a high end gaming system. - See more at: http://www.tomshardware.co.uk/forum/id-2547993/psu-tier-list.html#sthash.IBrtuyaA.dpuf

Ah, you did ask that in your original post, and I forgot. Sorry for my oversight. Just out of curiosity, did you watch the recent review by Jay? (below).

In answer to "that" part of your question, I honestly don't know. My knee-jerk response is to suggest purchasing the EVGA 980 Ti reference card, which only requires one 8 pin and one 6 pin. Reference cards keep the inside of your case cooler, the GPU itself is noticeably warmer, but the card is louder than a custom cooler. The Gigabyte card, according to Jay, is much quieter and the GPU remains cooler. Can enough molex connectors be combined to distribute enough power for an 8 pin PCIe power connector? My reference card came with a two 4 pin molex to one 6 pin PCIe connection. By Googling, I see that two 4 pin molex to one 8 pin adapter's exist, but I have no personal experience using them for such a powerful card. My understanding was that each molex supplies 30 watts by spec, so I'm not sure I trust those adapters, but as I said I have no experience with trying to make that jump. Perhaps someone else in the forum will know.

Anyone else know the answer to Kulwant's question?

Sell your VS650/get rid of it and go for a Seasonic S12II or M12II 620W power supply.
The VS650 is one of Corsair's worst PSU's and I seriously doubt will support a 980Ti.
If you're investing 60k+ on a 980Ti, invest some of those on a good PSU.

It will be fine. If you build it via PC Specialist with all the components in your machine, then select the VS 650 it says everything is fine:

Not the ideal way to work it out, but PC Specialist will tell you if you need a bigger/better power supply when you click proceed. FYI, I have a 5820k with a 650 CS and it says it's ok, despite the 5820k using a good 50 odd watts on top of the 4790k.
 
It's not about quantity, but quality. Cheap PSU's supply power which is worse than good quality PSU's, wearing out components and some going so far as to fry motherboards and graphics cards within months. And when one of these components goes out, there's no option but to replace it. Better sacrifice $20 now than sacrifice $1000 in 4 months.
