Choosing a PSU for a budget 500€ PC
So I'm building a PC for my brother, we already have a 7870 GHz Edition because it was on sale, and the following parts will be:
CPU: AMD FX Series FX-6300 3.5Ghz 6X
RAM: 2x Kingston HyperX Blu Red DDR3 1600 PC3-12800 4GB CL9
MOBO: Asrock 970 Pro3 R2.0
Cooler: Cooler Master Hyper TX3 EVO CPU Cooler
HDD: Seagate Barracuda 7200.14 1TB SATA3
Case: Cooler Master K280 USB 3.0
It's a budget PC like little more than 500€, and I don't know what PSU get him, when my friend build his 500€ PC he got Nox Urano VX 650W with a 7790 OC 2Gb, he says it's good, for the price obviously, other specs were similar. I need a budget PSU so I can't afford buying a AMD certified one for double price. They need to have 2x PCIe 6 pin, the full options are: there is more brand option is amazon.es, but the affordables for me are the same.
I need to spend less than 45€ so I will get one of these, which is better?:
AeroCool Templarius Imperator 550W 80 Plus Bronze 42€
Nox Urano VX 650W 42€
Corsair VS550 550W 45€
There is "Cooler Master E-600 600W" too, but with only one 6+2pin, so I don't know if it worth using an adapter, because it didn't came with the graphics card anyways.
The Nox has 2x 12V with 24A trail, the Aerocool has one 12V with 35A but it's 80+ plus certified if I understood all correctly, and the Corsair by brand seems the most reliable, but the Nox is 650W, also this particular Nox series and Corsair are made by CWT, while Aerocool by Andyson.
Here is link to their products in english: AeroCool Templarius Imperator 550W 80 Plus Bronze, Nox Urano 650W and Corsair VS550 550W I found a website with some information where I found that the corsair can perform Max. Load +12V for 504W, NOX 482W and Aerocool only 420W, but I'm not totally understanding how the 550W for same price can perform better than 650W, all supposedly are 85% efficient.
And also it needs to fit in the case "Cooler Master K280", but I think it should
