Is 620 Watts enough to dual crossfire 270x's?

guywhoknowsnothing · Feb 24, 2014

Can I crossfire dual sapphire 270xs with an antec 620 watt powersupply? I'm running an FX-6300, 8GBs of RAM.

You will need at least a good 700Watt supply. Take 300 watt for your overclocked system (FX-6300 ... ) to be safe
And + 400 watt for your two R9 270X's (will max consume 350Watt in heavy games, but 400watt with furmark)

So 700 is the minimum (I would take a 750watt

)

My system:

-2x 7870oc or somethimes my GTX 670Amp! (=GTX 770) or GTX 580, .... depends
what i m benchmarking. -i5 3570 @ 4.4Ghz!! stable (idle 28°c and max 40°c in
BF3)-Cooler Master V8 cooling -8GB G-skill RipJaws 1600 @ 1.35V -Cooler Master
Silent PRO M700 watt -Cooler Master 690 II Advanced windowed -Creative Sound
Blaster X-FI Titanium Fatal1ty Professional -SSD 128Gb OCZ vertex 4 -SSD 128Gb
Samsung 840 -HDD 500GB samsung

Since you will overclock that 6300 (or at least you better overclock it since that CPU literally begs to be overclocked) you would need a quality 700w from seasonic, xfx, or certain corsair. If you had a lower power CPU you could use a high quality 650w but amd once over clocked can use quite a bit of power.

Here's a seasonic that will work well:

I have a follow up question, this is my current motherboard http://www.asrock.com/mb/AMD/970%20Pro3/ can this overclock the FX-6300?

guywhoknowsnothing :

You wil to be able to overclock but not at the full potential of your 6300. Easy to reach 4.0Ghz, but beyond that it will be quit harder and temps will go higher. Its a limited board for a good overclock. But no really sense than, cause the turbo-clock is at 4.1Ghz if I'm not wrong. But the 970 AMD shipset will be fine if you consider not to clock above 4.2-4.3Ghz. You will be better of with for example the AMD 990FX shipset like the ASRock 990FX Extreme3 has.
