Go to solution Solved by Luke,

Yup you'll be fine. I ran a R9 290 off that exact same PSU and the 290 apparently consumes more power than 270 crossfire - http://www.ocaholic.ch/modules/smartsection/item.php?itemid=1359&page=14

 Hi, I have a Sytem that is running off of 2 r9 270's with 2 gb of gddr5 each without any overclocking. 

Yes, I know that 2 r9 270's in crossfireX is a weird choice, but I had reasons. Anyway, I have run

this through every psu calculator I know of, and since both cads only draw power from 1 6 pin pcie

connector, my 550 watt PSU should be perfectly suited to the task, with several watts of headroom. 

But then I read a couple of things about unstable voltages off the PSU frying cards! I know I have the wattage 

to handle both cards, but I was worried about the voltages.

     Can anyone tell me if my system will be stable at bare minimum? Thanks in advance, And

I will be upgrading the PSU ASAP anyway. Thank you, and here are the specs:

 

1 Asrock normal motherboard,

1 AMD A-86600k APU at 100 watt TDP

4x 2gb sticks of ddr3 1333,

1 seagate barracuda 7200RPM 1tb Hard drive,

2x r9 270's in crossfireX ( Powercolor turboduo model),

and the PSU is a SeaSonic S12ll-520 bronze. (it does have 2 6 pin headers.)

 

Once again Thanks for your help!

What the hell is an AsRock normal board, and can someone Photoshop this for me? I would, but I am working on something else.

 

As for the system, it should be fine. Your PSU is sufficient.

Really? I couldn't even run a 280 off a 550W. ThermalTake really must suck.

Thermaltake has so many different manufacturers that make their PSU's so it really depends on the specific model. Some are pretty decent while others are garbage - http://www.tomshardware.com/reviews/power-supply-psu-brands,3762-9.html

Yeah, I had a SMART 550W, couldn't handle my current system with any overclocks at all.
