Thread Details

I have a MSI Radeon RX 480 Gamer X on my Windows 10 PC and I'm concerned about how many watts its pulling down (possible cabling issue). Is there any software that will tell me that can tell me if its drawing enough power?

Not sure you can measure the wattage via a program, but you can get an idea if your power supply is good enough using a calculator like http://powersupplycalculator.net/

Thanks, but I'm using non-standard cable configuration and want to make sure my card is getting sufficient power (linky) from an over-sized PSU

I answered on that thread, btw, but one could easily argue that if your video card is not getting sufficient enough power, it will either not provide video to your monitor or will cause your system to lock up because it's trying to draw too much power than the Thermaltake can provide. With that 850 watt PSU, I think you're fine with ample power to the video card and the rest of your system unless one of those scenarios (no video or power lockups) have occurred.

Ok, good to know about those scenarios and neither have occurred. I'll try to stress the system out and see if I can make it fail with one of those. Thank you for the tip.

you're half right and half wrong. i also posted in that thread :}

it isn't about the PSU being 850watts. it is about the number of amps he is drawing from the rail he is connected to. I think if the GPU hits max draw (225 if i remember him saying was the max), he is pulling like 1amp over the rating (the molex line was 18A). that doesn't mean the card/system will fail but it can stress parts. The GPU takes power from the motherboard and from the 8 pin power input. so he might be fine too. (toms hardware did a write up on it. they used a riser or something to measure it from the Mobo and tapped into the 8pin cable to measure.

OP just buy that cable i linked to. you can probably get one for 5 bucks too on ebay. as we say around here, better to be safe than cw.
