PSU will keep up with the GPU?

[Andrei Haiu]

Greatings mates. Build:
-i5 4670 3.4Ghz
-Gigabyte B85-HD3
-PSU Super Flower SF500P14XE 500W Golden Green
-1TB Samsung HDD
-120Gb Intel SSD
-FullHD Benq Monitor
-2x4Gb Corsair Vengeance Ram

I've been using an Asus R9 290 for about a year and it stopped working, so I sent it in warranty and now I have to choose another GPU near that price. I chose the Sapphire R9 390 Nitro version and I want to know if my PSU can handle it. Since it kept with the 290 it should keep up with the 390 right? I've seen that in load it won't go over 500 but I'm not sure, so thats why I am asking. Help is appreciated.

Mmmmm, you're going to be cutting it very close even at nominal. That's a great unit, but even it will feel the strain if continuously ran at peak.

The power requirements are the same so it should "work" but TBH its 150 watts below recommendation. Luckily thats an excellent quality PSU but you may be under driving the card at max load. It could have even been the reason your other card failed.

I would consider a good 650w PSU

A 650 watt PSU with at least 42 amps on the 12v rail is recommended for that card. I think with a 500 watt PSU, you would be pushing that PSU for all it's got. Normal load for that card is 254 watts, torture is 323. Then add 84 for the processor and whatever else your system is running, your not going to have much headroom left.

Thanks for helping! I will get a better PSU when I'll be able to, but since then I'll run the 390 and try not to peak it at maximum. I appreciate the answers.
