Is this 500W power supply enough for the Limited Edition Sapphire RX 580 Nitro+?


I have this Fractal Design 500W PSU:
Fractal Design Essence Black 500W, FD-PSU-ES1B-HV-500W

My question is (as the title says) if this exact PSU is enough for this card.
If you didn't know already, this Limited Edition RX 580 is factory over-clocked to 1450MHz (stock is 1340MHz boost) and I've read about how power-hungry the 580 is.

I've previously tried out RX 480 (MSI Gaming edition) and only had problems with drivers (crashes).
Was able to OC the 480 to something around 1340MHz (don't remember exactly) and it was as stable as on the factory OC.
Except the driver crashes, I've only encountered 2 BSOD, while OCing to the max.

I've already ordered the card and don't really think that it could blow up my whole system.
Speaking of which, here are the rest of my specs...

CPU: Intel i5-6500 @ 3.2GHz ~ 3.6GHz
RAM: 2x 8GB DDR4 2666 MHz
SSD: Samsung 850 EVO 256GB
HDD: WD 1TB 7200 RPM
LED: 3x 60cm (2 have simple color control)
FAN: 2x 140mm, 3x 120mm
Msc: Simple keyboard, RGB mouse (Corsair Sabre Optical)

I did try out the wattage calculators online, but they've only got me to like 343W total. Which I think the 580 OC'd could take a bit more.

I'm not really thinking about OCing the 580 anymore (should be a good bin, but probably not really worth trying for the extra ~40MHz). My CPU has blocked multiplier and I won't be doing cross-fire in the future either.

Also on the side-note, think this purchase is wise? (Vega could have some cheaper variants, Volta might hit the market Q3/4...) I currently run on the integrated Intel graphics card :P

Thanks for all the lovely (and accurate) replies,

silent Tempest

    This card, specs on the Sapphire website, uses two pci-ex connectors, a 6 pin and an 8 pin. The link to Fractal that you gave says the PSU has the two connectors. So it should be fine.

    A couple of things you should know, if you don't already. One, overclocking usually raises the demands on the power supply by a lot, A LOT. If a component needs a 500W power supply, that's for normal operation. If you will overclock anything in your system, you will need more than the minimum amount of power.

    The other thing is not all power is available to all components. The CPU and videocard get their power from the 12V output. If you have a 500W power supply, that does not mean you can supply up to 500W to your CPU and videocard. That Fractal Design power supply is rated for 460W on the 12V. If the card requires 225W and the CPU 65W, you are at 290W just at stock speeds, and just for those two components. So don't think you have lots of power to spare, you don't.

    I think the card is a wise purchase. The truth is that there is always something better or cheaper coming in the near future. So if you will wait for Vega, why not wait for Vega II? Why not wait for Vega III? No, waiting only makes sense if you don't need the part now. If you need the videocard now, you buy the best card in your budget from what's available now.
