Hi! I am building a NAS with some old stuff that was laying around, nothing fancy! My goal is to centralize all my data in one place and periodically make backups to my Western Digital My Cloud EX2 Ultra (one drive only). I also want it to be a media center using Plex. I am not planning to add more HDDs in a near future, 4TB (RAID) is going to be fine for a while, at top I may be adding 2 more drives. If I have to think on how many hours it will be running on a daily basis I guess it would be around 12h but there will also be days running 24/7 when waiting for some download to finish.

What brings me here is that despite having an old PSU that I could use, I don't want to take risks protecting my data and want to make sure that I can get the most suitable PSU within my budget. I am buying from Amazon Germany to deliver in Portugal. My main choices at the moment are the Seasonic Focus GX-550W (84,99€) and the Corsair RM550X (79,90€). 85€ would be my top budget since I still have to handle delivery costs.

I know I won't be needing 550W but I think I can't go much lower with an identical tier unit. I tried to do an extensive search but at the end I got more confused than clarified, maybe for not having a great knowledge about power supplies.

Any opinion would be immensely appreciated.


CPU Pentium Dual-Core E5700 3GHz
6GB DDR3 RAM
Integrated graphics
1x SSD (openmediavault)
1x Hitachi 2.5" 7200rpm (Downloads folder for qBittorrent)
2x 4TB Western Digital Red Pro (RAID)

Both models mentioned are top notch. It would come down to support. Whichever model is easier to get support for, considering your location, would be good information to have in case you do have a problem requiring warranty service. I'd look into that.

Thanks for replying. I also had that in mind and as far as I could understand they are very similar but I will do some searching outside their pages. Thank you for bringing that up.
