5 beeps after changing to older GPU

[thekingofcss]

I bought a gtx 590 for 50€ to replace my gtx 650ti that provides less power and vram, but after i swapped cards the pc beeps 5 times and then goes to windows without posting and without detecting the GPU
Specs:
Athlon 860k 4.2GHZ
Asrock FM2A78M-DG3+
2x4GB 1866MHZ Kingston Hyperx Blue
Nox NX750W
Old gpu: MSI gtx 650TI 2GB GDDR5
BX300 SSD 240GB
1 TB HDD
250GB HDD

Here is the link to the Asrock beep code list. https://www.asrock.com/support/faq.asp?id=286

Says that there is no card detected, and since it was used when you bought it its probably bad.

He send me a video of the card working at FurMark so i dont think its bad. Also leds are working fine, no blinking so it can be the mb?

A GTX 590 requires a good quality 700w power supply with 2 8pin power connectors. What power supply are you using?

Yeah looking up a 590 can draw nearly 500 watts at peak so youll need a good 700 or 750 to be on the safe side.

Im using a NOX NX750W that provides to the v12 rail "theoretical" 58 amps and 696W to the rail, i asked to the guy who sold me the gpu what psu was using and he was using a CoolerMaster GXII 750W wich provides 60 amps and 720w so it doesnt make a big difference, tried with all the HDD disconnected and with an A4 5300 that i had from a quite time and still doesnt work, fan spins, gpu leds on and no signal.

Something that looked to me strange was when I changed the cpu to the APU, the motherboard recognizes a gpu hooked to the system and it will try to disable the iGPU but i only get signal in that case from the motherboard, so makes me suspect that the supposed 700W from the 12V rail arent real.

I will try to set up a psu to power only the motherboard and the cpu and the 750w to power up the gpu.
EDIT: Didn´t work so the last thing i can do its to try it with other motherboard, so for now nothing....
