GTX 770 takes 230 Watts and needs 550watt reliable supply like corsair. It needs 1x 6-pin + 1x 8-pin Connectors. The PSU mentioned will work fine because i'm using it.

I can not see that card needing more than 250-300 for it self. You should be fine with a power supply that has 600 watts on its 12 volt rail.

Please note that power supply is rated for 30c temperatures so ensure you have decent case air flow and a case with a bottom mounted power supply would be recommended.

The problem with the caps is heat more than anything.

For this reason alone Corsair recommends no more than 30c in the case.

The problem is just because a cap is rated for 105c does not mean it will take it forever. In fact they are also rated in hours of operation at this temperature. Some as low as 1000 hours(maybe lower if you look hard enough) and others much higher and 105 rated cap with 1000 hours may not last as long as an 85 degree cap rated for 5000 hours in a computer supply because they never get to these higher temperatures(lets use 50c all day). Now the 105 despite the 1000 hour rating does not fall that far behind the 85c capacitor(because the higher rating last longer at lower temperatures), but the 85c 5000hr rated cap would last about 15000 hours longer in this case(assuming 16 volt caps. 25 would last longer and 35 even longer).

For this reason alone. let the power supply deal with its own cooling(so have enough air flow to remove other heat from the case. bottom power supplies may be even better) and it should be ok.
