Can I use this SeaSonic PSU with a new build?

I currently have a 750w SeaSonic 750KM3 ATX 12V

My new build will feature an i5 6600k and a GTX 970. I don't plan on overclocking anything.

Will this PSU provide a safe level of headroom?

Is it generally a bad idea to use a 4-5 year old PSU with a new build?

Hoping to save a few $s if possible. Thank you!
 
Plenty big enough, plenty new enough, and high enough quality to continue using. Even with overclocking, etc this would be plenty. Even if you add a second gtx 970 and overclock this it would be fine. Capacitor aging is real, but it takes a long, long time and this has plenty of overhead.
 
The PSU has probably lost some wattage capacity, but even at 60% capacity (which is a very conservative number), it should be perfectly good for a 6600K+970.

Q: If you don't plan to overclock, why the K at all?
 
Thank you for the replies and peace of mind.

Is the 6600"K" mainly for those interested in OC'ing?
 
Sorry, I mean the 6600K. Amazon search says that the 6600-nonK is quite a bit cheaper than the 6600K.

There is about a 200mhz speed difference aside from the overclockability/unlocked multiplier on the 6600K.

Thanks! I've just started my research here on [H] and elsewhere, I guess I don't know exactly the best components for my needs yet, but it will be in the i5 and 970 combo range.
 
While you are researching, just maybe some additional pointers I guess.

Unless you are itching for a new rig, what you can do with your current is:

1. Overclock your current i5 2500K. This will easily match and surpass a stock 6600K. You will need a $30 cooler. A CoolerMaster Hyper212 will do decently, and the 2500K is a very good overclocker. You can target maybe 4.5Ghz easy.
2. Replace the 560Ti with a 970 or 390?.
3. Upgrade the RAM in case you need more.

You'll probably get the same performance as your proposed build for a lot less $.

The only thing I miss when moving from my [email protected] to my i5 2400@stock 3.2ghz when I need to are the USB 3.0 ports when making large file transfers, as the H67 does not have USB3 ports.

Good enough for SLI 970s. GTX 970s are not particularly power hungry GPUs.

Thanks for the suggestion! I am going to look into this - I could use the build money for a new monitor instead.

I currently have this CPU cooler XIGMATEK LOKI

In your opinion, would that be adequate? If so, would I want to re-set it if I were to OC the CPU for the first time?

If you're going to get a new monitor (above 1080p), you may want to put the CPU/MB/RAM money into a 980 or Ti.

Yes, your current CPU cooler should be good for about 4.5ghz, give or take 200-300mhz. Conservatively overclocked 2500Ks are good for about 4.2ghz at the minimum.
