Hey guys, pairing up an i5 2500K with an overclocked GTX 760 dual fan. Thinking of adding a 1TB solidstate drive. 8GB of ram for gaming. So wanted to know what you all think in terms of wattage? 750watt, 850 watt or higher? Keep in mind this is going to get daily heavy usage. I wanna make sure my system stays cool. Thanks in advance.

I'd go for quality over high wattage.  Unless it's extremely overclocked the whole system (assuming it's one GPU) probably won't draw more than 400w.  For example, an overclocked MSI GTX 760 HAWK card draws around 230w maximum (running Furmark or something), compared to 165w for a reference card.  To allow a good amount of headroom a high quality 600w-700w PSU would be more than enough.  Maybe something like this which is a very good and efficient PSU - http://pcpartpicker.com/part/seasonic-power-supply-ss660xp2 .  If that's too expensive then something like this would also be good - http://pcpartpicker.com/part/seasonic-power-supply-ssr650rm

It is an PNY overclocked 760 500W minimum requirement that almost blew out my previous Computer. So, I'd rather stay farrr on the safe side. 650W kinda concerns me. Lol spent so much money failing on this, I need. 120% safe one because I cannot afford to keep buying..

Almost blew it out?   What happened?  What was the PSU on your previous computer?

 

You can go higher if you like but don't skimp on quality by going for a cheap 1000w PSU or something.  Corsair, Seasonic, Antec are some good brands.  Better efficiency will equal less heat generated by the power supply itself.  The two I mention above are Platinum and Gold 80+ rated respectively, which means they are highly efficient all the way up to their maximum rated loads.

Cpu's shot up to 78C+ the power supply was low.. 460W(made the mistake of listening to Dell claiming I'd be fine.) I was debating going Corsair 850W enthuiast(spellcheck.) bronze lol really trying hard to not make another mistake.

A Corsair 850w PSU would be fine.  What is that, the HX series?

 

The CPU temperature is probably a separate issue from the power supply.  Can be just an insufficient or blocked cooler CPU, bad airflow through the case, bad contact between cooler and CPU etc.

No no no no, SeaSonic has a horrible record of failures. I would suggest CoolerMaster, Antec or Corsair. The 760 PNY should only use about 200-300watts, 400watt PSU would be too low. I would suggest any of those above that provide above 600 watts.

Just for info, Seasonic make PSU's for Coolermaster (V-series), Corsair (AX series) and Antec (various).  Also XFX PSU's are all made by Seasonic.  All I can say is I have not had a problem with them, nor have I heard of an unacceptable failure rate..

I've never heard that before, but whoever makes who, doesn't make it better. iPhones are made in China, but so are plastic bleep, called "toys". All I have heard about SeaSonics are nothing but bad things. :/

Yes, they are one of the OEM's for several other names, as well as units under their own name.  It is relavant that they make parts for these companies I think because they basically use Seasonic's base designs, with their own customisations and label.

 

Here's a few reviews of the items I mentioned above, some of which include strip downs of the PSU to look at individual component quality.  They are mostly good.  It's possible for the odd bad example to get through with any manufacturer.
