Hello. I bought R9 280x and I have 470W power supply. I will buy 600W PSU but my question is may I connect it to 470W just to try it out, I'll not play any games..I just want to see is it working?

    If not playing any games or doing anything remotely stressful with your GPU it won't for sure exceed the 470w mark.... the problems kick in when you start loading it with heavy tasks, and that's where you really need the extra wattage.

    One manufacturer XFX lists the PSU minimum as 750watts, seems odd as most others say it draws 250 and needs 600 minimum. So I'm not sure what the answer would be on your specific question, who's the cardmaker?

    The 600w unit is most definitely enough, given that it is a good one, from a trusted brand and that he isn't running 27,5 HDDs :P.
  4. I have AMD Radeon R9 280X Sapphire Dual-X 3GB. I just want to test it. Turn on my PC, see would it work, is there any signal and shut it down and wait for my 600W PSU to arrive. Is that good enough to test it?

    Yeah, if that's the case (and you're for sure that you won't get seduced by any game laying around) and testing the GPU is your main concern, go for it.

    EDIT: I meant Wattage not TDP.

    Oh and I don't disagree, however there does seem to be some differences between what one manufacturer says and what another one says, and the AMD site itself is down and can't see what they recommend so I've been going to various retailers to find recommendations. Some say it has a TDP of 250, others say 170. Very strange is all I'm saying. I usually just check 2 and if the information matches, as it usually does, I assume it's accurate, but this is the first card I looked up that had a variety of answers depending on the manufacturer.

    Card manufacturers and different companies will always leave a safety margin, which is bigger for some and smaller for other. Even the most high-end card doesn't usually surpass 500w under full load (e.g. GTX 780ti, at 430w total system).

    Exactly, but that XFX threw me, a single card requiring a 750w solution? Just seemed odd to me.
