Not necessarily XFX, depend on price in your country and what you need. Some other like "be quiet!", super flower, lepa are also good but not all series.
I am not fan of any PSU just usually take best price/performance, but currently in my PC is XFX 650W that I bought for 65€ and I was running my CPU, HDD, RAM, so all devices and also 1* 280X and 1*270 (mining ofcourse but 1 year ago) both overclocked to 1150/1500 for 280X and 1210/1450 for 270 and hadn't any problems.

Yes I misread. But actually this changes nothing. 280X stil uses the same, 550ti uses ~110W so total consumption is again over 350W and that is too much for 12V of your 550W PSU.
And by the way XFX is seasonic OEM so uses same parts.

Unlike other PSU vendors even the entry level range is Seasonic.
So even the cheapest XFX is same as seasonic not like lame Corsair that uses cheap materials for budget versions of PSUs and let buyers think that they made a good deal but actually bought "same shit" as LC Power.Thanks for the tips m8
at least i learn something 
so the next ps should be XFX!!!

So this is exactly what I wrote. Max consumption per GPU alone is ~250W in their test it is 243W.
Try buying for example XFX 450W, that has 34A on 12V, so much better than this crappy never heard of Heroichi.

Sorry for telling you, but this is crap PSU.(http://www.e-shop.gr/heroichi-hc550te-550w-green-80plus-retail-p-PER.700118) Only 28A on 12V, so it can only give out 336W so no wonder that under full load (GPU 250W+ CPU and other devices 100+W, together 350+W, but this PSU can give only 336W) it will restart your PC.

GPU's powered with a 650Watt Heroichi power supply. I assumed you misread the above. The fact you have never heard Heroichi doesn't mean anything. i've never heard XFX .... i'm familiar with thermaltake-hec-corsair-seasonic.
GPU's PS http://hecgroupusa.com/products/switching-power-supply/80-plus/ZEPHYR-MX-650/
Also those 2 Hec are leftovers from previous pc's.

R9 280X can draw power from PCI-E (about 75W) and from 6pin + 8pin (175W) or 8pin +8pin (200W), so max consumption is somewhere around 250W.

let me tell you my system configuration for this rig

Power consumption Radeon R9-280X DirectCU II TOP
System in IDLE = 119W
System Wattage with GPU in FULL Stress = 352W
Difference (GPU load) = 231W
Add average IDLE wattage ~10W
Subjective obtained GPU power consumption = ~ 243 Watts
1x Asus Nvidia GTX550Ti http://www.bit-tech.net/hardware/graphics/2011/03/15/nvidia-geforce-gtx-550-ti-1gb-review/10
System Wattage with GPU in FULL Stress = 248W
GPU's powered with a 650Watt Heroichi power supply. Using a 550w supply system restarts. So here is my proof that i'm not making assumptions.
Both power supply's are gold plus 80.
Wattage tells you nothing. You can have quality 450W PSU with ~450W (be quiet, XFX, super flower, seasonic, some Corsair series...) on 12V or you can have crappy 450W PSU (Lc power, energon...) with 300W on 12V. So quality PSU with 450W could be enough, but crappy can't.
Actually the 450watts is enough, but you can only run stock clock.
I have ASUS R9 290X taking 350-390W @ WALL with mobo/ram/cpu/hdd
R9 295X2 taking about 670-790W @ WALL with mobo/ram/cpu/hdd
Most likely your power supply does not provide enough power on 12 rails.

If the card is not getting enough power then the fans will be 100%
Put your ear to the fans and listen.
As soon as you start your computer fans will go to 100%, means low power or no power.

R9280x consumes 350W so 290 needs more to work and hash properly.
sorry, just not true, I have one... 
people should start to look at the spec. rather than making assumption
i'm using Asus R9280x-DC2T-3GD5 gpuclock:1080 gpumemclock:1600 using catalyst 14.6RC2. so MY card consumes 350W, dunno about yours. 24A at 12Vrail
That card btw had ROI in 3 months and since then all is profit. Was the days were doge had met moon! Epic days!!
(and 350W is probably the power drawn by the rig and not the card itself...)

If its not working try headless in Linux.
Maybe the card is damaged.

Depends on your 12v rail(s). Feed the 290X anything less than 25-30v and you'll get nothing.

450w and 290x is not a good combination to run.
