APC UPS issue

[Sarfrazio]

I bought a new APC-back UPS 600CI few days ago. It works fine under the normal load. But when I play games like battlefield 4 or start rendering 3D models, as I am a 3D modeller (3DS Max only), my UPS starts blinking RED and GREEN. Blinks and beeps every ~4 seconds. Any suggestion is appreciated...

I'd be inclined to think that is your overload indicator light, as in, you're drawing more than 350W from the UPS. What are your complete build specs?

you are right. That should be overload indicator.

My system specs :
Viewsonic VA1913wma 19" monitor
PSU : corsair 550VS
MSI 970 Gaming Motherboard
Zotac NVidia 750 TI OC
AMD FX8350 (Overclocked to 4.5GHz)
2 X 8GB DDR3 1600MHz
Corsair H80i Cooling Kit
APC backUPS 600Ci

Is the monitor connected to the UPS or just the PC? If the monitor is also powered by the UPS, take it off. If only the PC is powered by the UPS, then I'd think you can either dial back your overclock until you're no longer overloading the UPS or replace the UPS with one that can supply 450W or more.
Although I don't think your hardware itself uses more than 350W (even with overclocks), with the efficiency of the PSU, it comes to over 350W from the wall (UPS)

I underclocked my CPU to 3.2GHz. Its working fine now. But I had to sacrifice the performance.

But it's not fixed yet. Same thing is happening again after 15-20 minutes.

Still to much for the UPS. You don't want to run it near max capacity. Even if it's 350, you probably don't want to draw more than 275 from it.

Your UPS' AVR circuit can't handle anything over 360 Watts of AC power draw.

You need a UPS with much greater capacity.

With the CPU overclocked to 4.5 GHz the PSU's AC power draw could reach 440 Watts or more at full system load depending upon how much extra Vcore was required to reach that CPU clock speed.
