[SOLVED] Which psu should i choose?

[Damfino]

Hi, I'm from Argentina, first time i write even though i have used Tom's Hardware as a reference page before buying any computer part for years. This is the situation, I have an old computer (from 2010, my first pc), although now I no longer use it to play games (the last game I played was Deus Ex: Human Revolution in 2015) I use it every day for many things, up to 16 hours a day. A few days ago the power supply a Seasonic S12II 520W stopped working, (all the other components are fine).

After looking at what psu are available in my country, and considering how much I can spend, I chose two psu and I can't decide which I should buy.
I am between the Corsair CX550 and the be quiet! System Power U9 500W.

My specs:
Motherboard: Intel DG41TY
CPU: Intel Core 2 Duo E7500
RAM: Kingston DDR2 2x2GB
Storage: WD 500 GB Blue
PGU: MSI GT730 2GD3 V3 PCI-Express 2.0
DVD+RW Dual Layer LG GH22NS50
4 fans (3x80mm and 1x120mm)

As a reference, other power supplies that are currently in the Argentine market within the price range of those mentioned above are:
Corsair CV 450W 550 W and 650W
Corsair VS 500W and 600W
Thermaltake Smart 500W 600W and 700W
Gigabyte P450B P550B and P650B
Seasonic A12 500W 600W and 700W
Asus TUF 550B
