I'd like to know according to you- What PSU the average enthusiast build with Intel and a R9 290X needs.
Most i5's barely go over 150W total power consumption at stock - You have 300-350W free wich is normally what a 8+6 Pin GPU consumes.
And just because a specific card has junk power management it doesn't mean all 290X peak to 400W sometimes.
You keep saying 520W is not enough,yet provide no proof. "Experience and knowledge" is not proof.
And even if it was,review sites would have by far more credibility.
By the way...don't you think no OEM would put 8+6 pin to power a VGA if it wasn't enough...yet plenty of 550W PSU's have them...
Also i'd take a look at the 280X's power consumption..yep..totally NOT like the 290/290X
Please go read that article I posted and then come back and we'll talk.
Just because a card has an 8 and 6 pin connector doesn't mean it will only ever draw the rated power through it. Look at the 295x2, dual 8 pins on a card with two 290X GPUs. You can do the math. I'm not saying your 290x will do the same, but it can and will (at times) pull more than what those connectors are rated for. It should not be taken as gospel that that is all the power it will ever draw - "because connectors". It doesn't work that way.
There are plenty of lower power cards that use 8 and 6 pin connectors which are totally safe to run on your 520w PSU, that doesn't mean you can run any GPU, regardless, just because it has the same connectors. Again, it's not that simple.
Another thing about all these "reviews" you keep holding up as pure spoken truth; How long do these reviewer actually use and test these cards for? A day? A few hours? That's really about it. Just long enough to gather some number, slap them on a graph and show you where they stack up relative to the other cards on the market. The power consumption numbers are what they are, and again, that equipment is not inclusive of the true power draw characteristics of these cards. You'll also notice they don't use 520w PSUs for testing, they typically use units in the 750w+ range because they don't want anything to interfere with the performance of the components in their test system.
280X - 250w TDP
290X - 290w TDP
On a lower capacity PSU like the one you're using, that 40w difference can be the difference between being close to or on the limit and not.
The 290X doesn't have junk power management. Again, please go read that article. I'm not discussing this further with you until you do so. I don't have time for people who refuse to listen to reason and tell me I'm spouting BS. If you want to use your 520w unit, so right ahead. A number of us here have warned you.

All reviews show systems consuming 400-450 watts under a gaming load, and a tad over 500 in worst case scenarios when overclocking.
520 watts is fine for mild overclocking a 290X and an Intel chip. It's cutting it close, but is definitely OK if the PSU is decent.
When it comes to PSU's, "cutting it close" is not "fine". The PSU is the most important part of a PC. I just don't understand the mentality behind using something that is barely enough and putting the rest of the system/components at risk. You're all certainly free to use whatever parts you wish, but I will hold to the fact that saying this is "ok" is not ok.
