EVGA 980 ti ACX cooler vs EVGA 980 ti Superclocked ACX cooler?

[JoeyMartin1958]

Hello all,

Just two quick questions here. I have decided that I am going to be selling my GTX 780 and upgrading to a 980 ti. Looking at the different 980 ti models though, I'm left with a debate between two.
The EVGA 980 ti w/ ACX Cooler (Priced at $649.99 on amazon)
And the EVGA 980 ti Superclocked w/ ACX Cooler (Priced at $679.99 on amazon)
Upon looking at the specs, the only real difference I see is a slightly higher clock speed. Is this boost in clock speed worth the $30.00? I know it's not a big price difference but I'd prefer to not waste my money on something that would give be a boost of under 5fps.
My second question involves the PSU of my system.
I currently have this card. Both the 780 and 980 ti have TDPs of 250 Watts. I have a 600w PSU (this one) currently and am not having any issues with it. I still would plan on upgrading my PSU later this year for one of a higher quality, but is it neccesary to upgrade now due to a higher power consumption of this card?

To summarize my questions:

1. 980 ti ACX vs 980 ti superclocked ACX, is the Superclock worth it for $30.00?
2. Would there be an increase in Power consumption when going from the 780 to the 980ti? I currently have a 600W PSU.

Thank you all so much!

Th regular will higher than an SC - they both have the exact same OC ceiling.

The GTX 780 was -- and still is -- a great graphics card. Without checking to confirm, 780 was the Kepler processor. 960, 970 and 980 are Maxwell. Across the board, Maxwell uses less power at its maximum extreme than a Kepler. I am quite sure that a 600W PSU of good quality should be enough to handle either generation and model of those NVidia cards. Add a second card, however, and it would push the power draw higher than the mid-500s of watts. It is so close that I would recommend a 750 or 850 over even a 650. On the other hand, my 650W Seasonic is just fine for handling 2x GTX 970 SLI.

Good power supplies should actually handle wattage exceeding there spec, some known to provide consistent 80-something-% efficiency output to beyond 100W over their spec before the safety circuitry trips the PSU to shut down. I trust this to be reliable for Seasonic PSUs before any other, partly because I've used them a long time, and partly because the test proving maximum sustainable output had been performed on an XFX 750W PSU which was a re-branded or re-badged Seasonic. IIRC, the measured output before shutdown of the XFX was at least 910W. There are other good PSUs; look for tests at Xbit-Labs and Tech Report. Anandtech and Tom's have done revelatory PSU review-writing.

On the angle of the 600W unit, I personally would look at its use or age in comparison to its warranty period. If you chose the PSU because it had the highest of industry warranty periods, that would be "close to 5 years." A $20 hand-held PSU-tester can -- well -- come in handy. If sleep and hibernate operate reliably with the PSU's current deployment, then it's probably a safe bet.

3 months ago, I replaced a system that had been running since 2008 24/7, and only sleeping about half the day for the last three years. It was a Seasonic 650. I might have kept it, because it seemed to be working fine. But I recycled it after trimming the cables for spare parts. I suspect that any extended periodic sleep is bad for a PSU, although the frequency of use was fairly high for that unit. To do over again, I would have implemented a scheduled sleep after 2 hours and a hibernate after 3. 5 years was good enough; 7 years was more than expected.
