The rule of thumb that most gamers use is to take your wattage consumption and multiply by 1.5. 578 x 1.5 is 867 watts you could probably save some money by buying a 900-watt power supply. The power supply you have currently I wouldn't recommend using as any up serge of the base if above 22 watts could potentially fry the northbridge then you would have to get a new motherboard. I would buy the power supply first then the graphics card. This could potentially save you a lot of money if the mishap did occur. It is your choice though.
Sorry, there was a problem. Please try again later.I've seen lots of answers to the power supply questions. I'll give you a few facts to think about and make my point. First, the enemy of electronics is heat. If you read your power supply docs you will see they are most efficent right around 50-60% load. Note that on my PS it is 4% more inefficient at top load. That is 4% of 1000 watts turned directly into heat!!! Not what I want. So if you "use" 500 watts, highest efficiency to have a 1000 watt PS. Notice in your PS docs also that the fan noise dramatically increases as you near 100% load. That means it is working as hard as it can to cool the transformer and capacitors (etc). So, now you might run at 578 watts on a 600 watt power supply. But then, you have to worry about do I really have good airflow to cool the PS? Heat will eventually breakdown the physical materials in the transformer and it will die. I hope it does not catch fire. Another item that is important is that while you might see the system using on 578W at a given time, there are initial startup or "rush currents" that can draw higher power when things are turned on say from Windows desktop to running Crysis at 4K! You ase firing up disk load and graphics load and cpu load and you have a high demand on the PS. I always recommend to try to have a PS that 2X what your normal load is to give you margin on startup and best efficiency.
Sorry, there was a problem. Please try again later.Is it recommended? No. Will it work??yes. Will it be stable?? Only time will tell. I would do 700 plus with rtx 3070 and beyond. Right now I have a new build with a Seasonic 850w, waiting for the rtx 3080 or 3090... haven’t decided yet if I want to splurge on the 3090 or save my money and get a 3080 plus a big Navi for my other build.
