How much power would I need for an i5, 8GB of ram and a GTX 760?

post #1 of 10
Thread Starter 
Hey guys and gals,

Just want to check this with you guys. I'm building a new rig for a friend and I'm not sure what size power supply to go with.

We're throwing in an i5 4670k, a GTX 760, 8GB of ram and putting them on an Asus Z87 Pro. I was thinking 750Watts or more but not quite sure. What do you guys think?

P.S. I do plan to OC it. Let me know what you guys think.

Thanks smile.gif

750W is overkill and plenty of power

Grab a good 550W unit like an XFX or a Rosewill Capstone and you're set.

This^ We have other members powering it with 450w with no issues. Just depends if you ever plan to expand on the computer in the future

My sig rig runs on a 450 watt capstone no problem. With my overclock of 4.2 on the cpu and 1150 on the gpu.

450 watts is more then enough for that system

Even with two of those cards you could power them with a 650 watts

I'm soon gonna be gambling an OC'ed 4670K, 8GBs of RAM and a GTX 770 with a Corsair CX500M.. I'm pretty sure it'll work fine but the question is for how long? With factors like heat and capacitor aging anything can happen. A reputable unit with a good warranty and a little bit more wattage than your system will be drawing really helps down the road. Try using eXtreme Power Supply Calculator Lite, it'll help you determine roughly how many watts you'll be drawing.

Just last month I had to RMA my Corsair HX750 (in sig), it died after four years of mild usage and my system only draws around 500 watts. bigeyedsmiley.png Gotta love that 7 year warranty.

I hope you get your HX750 back, the CX500 is pretty average
