Is an R9 270x compatible with a 430w psu?

[Nerderama]

I have a 430w PSU and i plan on upgrading my graphics card to a Sapphire R9 270x. I dont plan on overclocking my gpu but i do plan on overclocking my cpu. I just wanted to know if an overclocked Athlon 760k and R9 270x will run on a 430w power supply?

Minimum recommended is 500w. You might be ok at 430w but why chance it?

The GPU is already expensive by itself so I really dont want to spend more money for 70 more watts or so.

What's the brand and model of the 430W PSU?

It's the PSU's maximum combined +12 Volt continuous current capacity that is what determines if it is sufficient or not. Saying that you have a 430W PSU is pretty much meaningless.

The PSU also needs to have a sufficient number and type of PCI Express supplementary power connectors.

My psu is an EVGA 430w psu.

System Power Supply Requirements for a single Radeon R9 270X
• AMD specifies a minimum of a 500 Watt or greater system power supply. (Minimum system power requirement based on a PC configured with an Intel Core i7 3.2GHz 130 Watt TDP processor.)
• the system power supply must also have a maximum combined +12 Volt continuous current rating of 30 Amps or greater
• the system power supply should also have at least two 75-Watt 6-pin PCI Express supplementary power connectors.

Total Power Supply Wattage is NOT the crucial factor in power supply selection!!! Sufficient Total Combined Continuous Power/Current Available on the +12V Rail(s) is the most critical factor.

Overclocking of the CPU and/or GPU(s) may require an additional increase to the maximum combined +12 Volt continuous current ratings, recommended above, to meet the increase in power required for the overclock. The additional amount required will depend on the magnitude of the overclock being attempted.

EVGA 430W [100-W1-0430-KR]
• OEM: HEC
• maximum combined +12 Volt continuous current rating: 34 Amps <===== Sufficient
• one 150-Watt (6+2)-pin PCI Express supplementary power connectors <===== Insufficient
• Modular Output Cables: No
• Meets Official Intel Haswell Compliance: No
• 80 PLUS Standard Efficiency Certification
• 3 Year Limited Warranty
