Would an older Corsair HX650 Power a R9 290X

[Grey M@a]

Just wondering if anyone has one of the older Corsair HX650w PSU's and is powering a single R9 290X, this one in particular:

PSU: http://www.techpowerup.com/img/09-09-15/144b.jpg (Linked to image and not another store, hopefully this is ok, loads an image only not a site etc)

GFX: https://www.overclockers.co.uk/showproduct.php?prodid=GX-330-AS&tool=3

It states it needs a 600W PSU but just wondering if this will be enough with the system I have.

My current specs are:

4790k 4GHz Devils Canyon (Runs at 4.4Ghz at present - slight overclock)
Gigabyte Gaming 7 z97 motherboard
16GB DDR3 Corsair low profile
1TB WD Black
128GB Samsung Pro SSD
Corsair H100i cooler

This is all that is in the machine as its a gaming rig but currently running on a 7870 XFX black edition card with no issues.

Just wondering if its worth getting a slightly higher wattage PSU, was looking at the SuperFlower Leadex GOLD 850W Fully Modular "80 Plus Gold" Power Supply from OcUK.

Thanks for any advice.

I have a TX650 powering my 290x system without issue (though I am using i5 not i7).

A stock 290x would only consume around 230-270W on average during gaming...it is only when highly overclocked that it would peak at 330W from time to time.

Thank you very much Marine.

I would be running it at stock and then maybe 24 months down the line look at the R9 300 series cards if games required it

Thanks again.

I could push my 290x's core clock from 1000MHz to 1080MHz on stock voltage, so you could try the same to see how far you can push yours on stock voltage. Power consumption shouldn't increase too much if you are not raising the voltage.

As for how far memory clock would go, it is really chips lottery. Some 290/290x memory won't go any further than the stock clock 1250MHz, while some would go all the way up 1625MHz. From my experience, raising voltage make next to no difference in stablising overclock for the memory, so it's all down to luck. For example, my 290x the max stable memory clock is 1375MHz and no higher (do note that if you get "black screen", 99% it is a sign of unstable memory clock).

Thanks for the heads up, will have a play with the settings when I get the card in my mits
