750w PSU for r9 280 Crossfire?

[TrancëJay]

Hello!

Quick question:

Will this psu http://www.aerocool.com.tw/index.php...ator-750w-spec

handle a r9 280 crossfire of this http://www.sapphiretech.com/presenta...n=&lid=1&leg=0

?


I made a simulation @ eXtreme and got the following:



But I thought it was to low

I wouldn't worry about the PSU, I would worry about the fact you have stuck such a weak CPU with two medium-high GPUs in Crossfire. Its going to bottleneck your GPUs.

PSU is fine, the extreme psu calc always overestimates on power needed. you could prob to trifire with those and that psu.

despite what scubar says,
even at stock that cpu is more than enough to max out those gpu. but an overclock would help you.

Your PSU will be more than ok with that setup. Check what i'm running on a 650W Corsair TX: FX9370, R9 290, 2 sticks of ram, 1 ssd, 4 hdd's, 2 MCP355 pumps, 10 120mm fans, 2 140mm fans and 2 fan controllers.

PSU calculator says the following:

Minimum PSU Wattage: 841 Watts
Recommended Wattage: 891 Watts

Just to give you an idea of the overestimates of those calculators.

Thank you all.

i3 4130 is just temporary, I have ordered a 4820k + AsRock X79 Extreme4.
