Will the 450W SFX PSU run my system and GPU?

[DragoniaBlu]

I'm going to be starting a Mini-ITX build and wanted to know if any one has any experince with any SFX power supplies? I'll be getting the Silverstone 450W SFX12V and the rest of the spec for my computer will now be -

Intel Core i7-4790 3.6GHz Quad-Core
Asus Z97I-PLUS Mini ITX
Corsair Vengeance LP 16GB (2 x 8GB) DDR3-1600
Crucial M550 512GB M.2 SSD
Crucial MX100 512GB 2.5" SSD
Silverstone FT03B-MINI (Black) Mini ITX Tower
Silverstone 450W SFX12V
GPU - R7 260X or R7 265, (Undecided) I'll be using all Adobe software thus the OpenCL performance was recommended to be over the Geforce 750 which I had originally intended to get.

Any thoughts on whether the PSU would be enough?

Which one is it the ST45SF-G or ST45SF? although ether one should be fine for that setup

what case are you looking at?

[DragoniaBlu]

I PSU will be the modular 80+ gold one - the ST45SF-G.

The case will be the Silverstone FT03B-Mini.

I never know how powerful my PSU really needs to be.
on my last build I had a 750W supply and I was just a complete waste lol

You will be fine as the system will consume well under 300W at the wall. I would probably guess at most around 220W.

More than enough power. It has a single 12v rail of 37A giving 444w. It's built by Enhance Electronics and has been getting very good reviews. The 260X and 265 have relatively low power requirements and along with a non clocked cpu will leave you with a decent amount of power spare.

Yes it is more than enough

Awesome guys. Thanks. I was starting to query it cause the gf760 card I had thought of before didn't even need any external power plugged in. The radeon cards will and it just put a little doubt in my head
