I want to buy the newly released version of RX 460 4GB from msi
https://www.msi.com/Graphics-card/Radeon-RX-460-4G-OC.html#hero-overview
But currently I have a normal commercial power supply (500W) which is capable of running my old card GeForce GTS 450
Because It does not have a direct 6-pin power connector, I am using a 2x4pin molex converter
I do not want to take any risk with the new card but since It does not require an external power connector, Will my PSU be enough for It ?

Hello... You will be on the "edge" with the q6700... @15 amps and within Spec... Basically heat kills any thing electronic, so make sure the fans in PS and Case are clean and clear for Air Flow... and your Room temperature is not excessive Hot or humid B )

I would suggest planning on getting a NEW/different Power Supply when you do your next future system upgrade/Gaming machine. Pay attention to the +12Vdc ratings on the label for your Planned GPU and CPU needs.

Make sure your MB has the BIO's update needed for MB comparability for the q6700 too B /

Hello... 1) Open up your case and take digital of the PS electrical spec label and upload to IMG poster and post the address here for us... we need to look at the +12VDC Output current or wattage rating to do the Math.
2) What CPU are you using? this needs power from the +12 V rail too.

Basically it is only a 75 watt LOW power card... and I Don't see any power connectors on it... B / the power will come from the MB PCIe x16 connector B )

Hello... Great Pic THX B ) your Label states having 18Amps @+12Vdc or 216 watts available for CPU/GPU/? use...

Well now the math... (CPU e7400) 65 watts + (GPU RX460) 75 watts = 140 watts from +12 Vdc rail 140/12= ~11.7 amps needed.

(CPU Q6700) 105 watts + (GPU RX460) 75 watts = 180 watts from +12 Vdc rail 180/12= ~15 amps needed.

You can see now that some Stated "500 watt PS" are not really what they say they are when it comes to powering a CPU and GPU in a "Gaming system" As a consumer you need to always look at the label and do the Math to make sure you get what you need B )

So according to this calculations, I think It is sufficient right ? (for the q6700 and the RX 460)
because the GTS 450 requires 106 W and It is working just fine with e7400
