Right now I have a 7970 ghz edition which is overcloked to 1120 mhz and my psu is: http://www.newegg.com/Product/Product.aspx?Item=N82E16817139027

I can run it pretty well on all benchmarks, but im planning to move to nvidia and it is the asus gtx 770, so my question is, will it run it? on nvidias site it says min. 600w but benchmarks shows otherwise: http://www.techpowerup.com/reviews/ASUS/GeForce_GTX_770_Direct_Cu_II_OC/25.html

According to the review I should be able to run it better than my 7970 ghz edition? and im not going to oc the 770 even further that it is from ASUS.
 
Solution
Moving to gtx 770 is not at all a upgrade they have similar performance in games if you want an upgrade then go for gtx 970 4gb its 329$.

Plus the gtx 770 requires 42 amps and a minim of 600 watt of PSU so not suitable for your PSU.

On the other hand the gtx 970 requires 28 amps and a 500 watt PSU and has a max TDP of 145 watt compatible with your PSU.

gtx 970 is even faster than the gtx 780 and similar to gtx 780 ti in performance.

What CPU are you using but by the sounds of things your 7970 would use a lot more power so I would be very surprised if you couldnt especially if your not planning on overclocking a factory overclocked should be more than fine.

The GTX 770 uses less power than the HD 7970 GHz edition (230W compared to 250W).
You have a very heavily loaded power supply and the quality isn't that great to start with.
If you are considering the GTX 770, you should really look at the GTX 970.
The prices are similar, the GTX 970 is much faster, has more VRAM (4GB compared to 2GB) and uses less power (145W compared to 230W).

Really neither of these cards is a substantial upgrade from your current card.
In fact, with 2GB VRAM on the GTX 770 and 3GB on the 7970 GHz, this is a downgrade.
The usual rule of thumb is at least three tiers in the hierarchy:
http://www.tomshardware.com/reviews/gaming-graphics-card-review,3107-7.html
The GTX 970 will slot in with the GTX 780 and Titan, one tier above the HD 7970 GHz edition.
The GTX 980 will slot in with the GTX 780 Ti and Titan Black, two tiers above the HD 7970 GHz edition.

If all you really want to do is move from AMD to Nvidia though, the GTX 970 is the best choice.
 
gtx 770 draws less power but requires 42 amps compared to 31 amps on hd 7970 and the gtx 770 and gtx 970 price are not similar there is about 50$ difference but getting the gtx 770 instead of gtx 970 just for 50$ is a foolish thing to do.
 


i dont know why are you switching your card to a same card which will give you same fps in games actually lower in some games compared to hd 7970 (r9 280x)
 


He said he is swapping the card, not buying new.
Where do you get 31 amps from for the HD 7970 GHz edition? That isn't nearly high enough to run a system with this card.

Celil, Don't swap the GTX 770 for your current card. It has similar speed and less video memory.
 


I thought swapping means changing it for a new one anyways not that good in English.

watch this site the hd 7970 requires same amps as r9 280x.

I will switch it because of nvidia psyx and better drivers. I just want to know if my 500w corsair can handle it? it has 38A and the 770 req. a 42A or? so will it damage the card?
 


No pls dont use that PSU with gtx 770 either get another PSU or keep the GPU .
you PSU can burst and along with it other components can get damaged.
 




Recommendation from Nvidia is for a 600W supply, but this is a generic recommendation not taking in to account your other components or the quality of your power supply.
Your system will draw about 350W at full load, mostly on the +12V rail.
This is about 77% of the rating on your power supply, anything under 80% is fine.

If you do exceed the rated current for any reasonable power supply, it will simply turn off. You don't have to worry about other components being damaged.
You will be fine if you want to use this video card.

Am sure 42amp is a recommendation for the whole system not the card itself from Nvidia which is normally far from what it requires I mean obviously better safe than sorry but I believe this has been discussed before hand in this previous forum http://www.tomshardware.co.uk/answers/id-1991675/question-gtx-770-amps-required-12v-rail.html & http://www.tomshardware.co.uk/answers/id-2159471/evga-770-amps-12v-rail.html which is the reason I asked your cpu as an AMD bulldozer with this card might be abit much but an i5 or i7 should no problem provided there not overclocked.
 


Don't use this list as a reference, it is rubbish.
It shows the GTX 780 with a minimum 42A.
It shows an R9 290X, which has the same 250W TDP as the GTX 780 and typically uses more power with a minimum of 33A.
With a 125W CPU in a typical system, both these cards require a supply with a +12V rating of 44A (good quality 550W power supply).
 


As explained earlier, this card uses less power than the one you have.
There are no guarantees on how long your power supply will last. The CX series use cheap capacitors and isn't expected to last as long as a better power supply.
Eventually you should consider getting a better quality model at least 550W, but for now you will be fine.
