I'm using a Cyberpower 550. They new model is 600 or 650.
You need a 1000w if you do heavy OC'ing.
I'll tell you why.
I run my CPU at 3.08 instead of the 2.93 stock setting with no problems.
I never came close to maxing it out.
But if I OC to 3.8 it messes with the 550W USP.
It can not supply enough wattage.
I'm talking about with AC power on not on the battery only.
My system draws 600-650w OC'ed to 3.8 and so maxes the UPS out.
You can only draw what the UPS allows which is 550W it is rated.
Anymore and it will burn out quickly
They don't tell you this in any of the specs but the UPS watt rating is maximum UPS draw allowed ALL the time. Not just battery time.
My PC ran with the 650w draw for a few seconds and I had to shut it down. The alarms were going nuts on the UPS. It won't sustain that output.
Like taking a power supply rated at 6A and the surge rating may be 8A.
Then put a 10A load on it.
For a few seconds surge power will work but it overheats and dies quickly.
If you don't OC heavily you will be fine with the smaller 600-650.
If you OC heavily go with the 1000-1200.
Something I never thought of before I bought mine and found out by experience.
