Cables from g3 650w / 850w

Recommended Posts

Posted · Original PosterOP

Hello all, 

Quick question before i pull the trigger on buying a new psu. I currently have a 650w g3 psu, will those exact cables work with the 850w g3 model? Can I just unplug and plug in the new psu without rerouting all my cables?


Current System: i7 8700k (OC'd 5ghz), GTX 1070 Ti, Z370 Hero Maximus, 16GB 3000mhz Ram, corsair 460x, 500gb 960 EVO, 750w HXi PSU, 5x ML140 fans, 1440p 144hz Gsync Monitor.

Why are you replacing a 650w G3 with a 850w G3?

Your PC doesn't need 850w. The only reason I would change the PSU is because of the issues inside of the G3, not the wattage. 650w is perfectly fine for your system, even with the 8700k overclocked.

Are you doing VEGA 64 LC Crossfire or what's your plan?
Dual LGA2066??

My pc isnt updated, i apologize. I now have a 2080 ti with my 8700k. That is the reason I want a bigger psu. 650w is hitting the limits. Now... will the cables work between the two models?

You are not going to push a 650W PSU to its limits by powering a ~350W PC with it. You don't need to upgrade.

How often are you running LN2 cooling on your CPU? Because that's the only way you'd be "hitting the limits" of a 650W PSU with a single 2080 ti and 8700k.

My OC on my 8700k and my old 1070 ti was fine, ran perfectly fine. Now with my 2080 ti and my OC on the cpu, when I load up anything intensive, like BF5 after 2-3 minutes I bluescreen. Took the OC off, now running fine.

Sounds like a stability issue with the overclock then. Run Prime95 for a few hours when you set your CPU overclock to test the stability of the system. You may need to lower your clocks or increase the voltage slightly.

Stock 2080Ti is ~250W. 8700k overclocked to 5GHz is ~175W while running Prime95, and way less during gaming loads. There's no way you're hitting >650W. You'd just be wasting your money on a new PSU that won't solve your issue.
