Cpu power consumption

I want to buy an FX-8350... it says that its avreage of Power Consumption is 125w which i think isn't true i saw alot of reviews where on idle it runs on about 80-90w and on full load around 200-300w anyway since i will be getting a graphics card which is R9 280x that consumes around 240 combined with the 8350=230+240 will a power supply of 500w be enought because i will be gaming on my rig and i'm not sure if it will be enough

    8350 stock will definietly use 200w at full load. if you overclock it with a liquid loop up to like 4.8 or 5.0 ghz, then it will eat up 300w at full load.

    you'll be ok with a good name brand 500w if you're buying a stock reference 280x and planning to leave the 8350 at stock speeds with stock cooling unit. a cheapo 500w will probably have issues.

    but considering a 700w is probably only $20-$30 more... get the 700w so you have some room to grow and do some overclocking at some point

    I don't know if you're trolling or what, but the 200-300W on load means the power consumption of the entire system, not just the CPU. There is no way the CPU could use much more than 125W on load, why would AMD give false numbers?

    UPDATE: With these specs: http://www.bit-tech.net/hardware/2012/11/06/amd-fx-8350-review/2

    The entire system uses this much: http://www.bit-tech.net/hardware/2012/11/06/amd-fx-8350-review/7

  3. I would go for a quality 550watt but if you already have a quality 500watt it will run it since system load is going to be around 400watts. http://anandtech.com/show/7400/the-radeon-r9-280x-review-feat-asus-xfx/20

    Have a look at Eduello's post. He is 100% correct. You need to rethink your numbers for sure. They are WAY too high.

    That's what i was looking at as well since i will be gaming i will probbably stress my cpu by 80-90% so i saw that on full load the 8350 consumes 213 that's not what amd said it sais 125 watts... that is a big difference but anyway the 213w + the r9 280x that consumes around 239 watts means i that i have to get a minimum 600 to 700 w psu right?
  6. This is measured with a 6 core intel which is power hungry http://www.anandtech.com/show/7400/the-radeon-r9-280x-review-feat-asus-xfx/20 a quality 550watt like XFX will handle it fine and better than a budget 600watt.

    The CPU doesn't take 213W to run at full load, the entire test system does! The wattage draw is recorded from the power plug so it is the entire system. Also, that system has a GTX 690 in it, which uses a lot more power than your card.
