Hi guys,

I have an HTPC build with a 300W micro-ATX PSU. The brand name is circle and it was built in the case when I had purchased it.

My processor is the intel i5-4430 3.00GHz. I don't have another GPU as I only use the built in iGPU.

I am looking to purchase this graphics card:

http://www.newegg.com/Product/Product.aspx?Item=N82E16814500402&cm_re=gtx_1060_mini-_-14-500-402-_-Product

I have benched the peak load for my processor and it seems to be about ~90W. This leaves about 210W for the 1060.

I have seen the results where the max load for 1080p gaming is about ~90W. This leaves me about 120W free for the system to use.

I was wondering if my calculations are relevant and I should go ahead with the purchase?

The total system power consumption with i5 + GTX 1060 is 200-250 watt under load depending on the exact CPU model, MB , RAM, number and type of storage, fans and whatever else you have in the system.
A 300w of EXCELLENT PSU would be sufficient.
I'm not sure it's the case with your PSU. it supposed at least have the close to 23-25A on 12V on the label. And even if it does, it supposed to be designed to work under such high capacity.
I'm not aware of any micro ATX PSU that is rated even for 20A on 12V. Not to mention that it's better to have at least 20-30% headroom.
