80 plus gold 300w can run r7 260X ?

[Le Ba]

Hi all, I am using this KRPW-TX300W/90+ 300W 80Plus Gold , a TFX psu in my custom case. It is running a overclocked G3258 4.2ghz 1.25v and a sapphire R7 250E just fine ~~ whisper quiet. There is r7 260X on sale (~90 USD) so I wana give it a try but I am not sure if my psu is sufficient . Thanks all !

The R7-250E is only a 55W card and runs off the PCIe slot power alone. The R7-260X is a 115W card and requires a 6 pin connector for aux. power. I seriously doubt the 300W TFX PSU would handle it. At least not for very long. If you can post the nameplate specs on the PSU, I'll verify. But I doubt you'll want to use that card and/or that PSU.

You may want to consider the GTX 750. It is as fast as the 260X and needs only the same 55W as your R7-250E.

Recommended PSU for 260X is 450 watts. If you want to use existing PSU get GTX 750 ti as suggested already.

That's a TFX PSU with a pretty decent rating for the +12V rail. But personally I would not use it to power a 115W R7-260X (plus the rest of the system). Especially since you OC the CPU. There's really no need to take the risk since the GTX 750 Ti is slightly faster and is only a 60W card.
