2 PSU for Extreme Overclock

[Cristian Dobre]

Hi ,

My setup :
CPU : FX 8350
128 gb ssd + 500 gb hdd
DDR : 2x4gb
GPU : Asus Matrix r9 280x
PSU : 650 W Nox Urano

I want to overglock the GPU from 1100/1600 to 1260/1925 it will consume 550 Watts in overclock mode.

Now is cheaper to buy a second 500 W PSU and conect only the GPU to the old one and the rest of the PC to the new one.
How i start them in the same time ? It is safe?

The R9 280X won't take 500W overclocked. At most it may be 250-270 Watts on its own.

The person who did the review is wrong. A decent quality 550W psu will be enough like XFX 550W even with overclocking.
A R9 280X matrix has two 8 pin PCIE. The total power that it can draw is up to 375W. It will not take anything higher than that.
