Can a silverstone 450W Gold certified sfx psu power a Sapphire R9 290? I did a little bit of research and found out its drawing around 300W. Just wanted to make sure everything will be fine. I wont be overclocking the gpu nor the cpu.

Thanks in advance!

I was looking at the same combo (and using the new RVZ01 case to build an HTPC/Gaming box) and I've backed off for the following reason: the 450W PSU SHOULD be enough to power the card and components (I built mine around i5-4670 and R9-290 Tri-OX which comes out to like 410W max draw) however the Gold SFX PSU only puts out 37A on the 12v rail which is below what the card requires (40A).

I think this is a risky solution.

My two cents, I've given up on using the R9-290 in an...

Several websites like anandtech has this graph that shows its drawing below 400W and thats the total system wattage. This card would be great for my ft03 mini (with case mod). Darn you steamboxes.

you can do this but lets say it like this..
i have an r9 280x and had to replace my 530w psu to a 750w psu
so you can go with the 450w but defnitely dont be self confident that itll work perfectly fine

I would recommend a atleast a 750w power supply. You also need to make sure the power supply has atleast 40amps on the +12V rail to power the card. Also if you get a new PSU you can know It's future proof so if you upgrade your PC you won't need to change the PSU again!

Hope this helps

My two cents, I've given up on using the R9-290 in an HTPC purposed box, instead am building around a GTX770 (MSI TF 2GB) and using the Silverstone GD04 case (which allows you to use a normal ATX PSU but restricts your card length to around 11", to short for the Saphire R9 card). Note that the depth of the case is a restriction for me, which is why I am going with the GD04 instead of a GD08 which CAN accommodate the R9 card and a normal ATX PSU.

Just don't overclock the card or remove the voltage limits and you should be fine. But it really depends on your CPU. I wouldn't go with a 450 Watt if you have an AMD CPU, it would be coming in at 444 Watts, which is very close. If you have a non Extreme Edition Intel CPU, then you are fine.

Sorry to revive an old thread, but where did you find that info? I'm currently in the same boat, only I've already ordered the parts and put the system together. It ran fine for a while, but now I'm having problems (roommate knocked my pc off the coffee table).
