Hi.
I have an old system (i7-870 and AMD 6970) and i need a new psu. Max load wattage according to outervision calculator is ~500 w and minimum recommended ~550 w. Now where i live my choices are limited. I can find a few descent low budget psu's like the ones below
1.Be Quiet System Power 9 600W - Bronze
2. Be Quiet System Power B9 600W - Bronze
3. Be Quiet System Power 9 600W CM - Bronze
4. CoolerMaster MWE 600 White 230V - V2
5. Corsair CV550 - Bronze
6. Corsair CV650 - Bronze
7. EVGA 600 W1 - White
8. Thermaltake Hamburg Pro RGB 550W - Bronze

if none of the above is not recomended, for a few more euros i can also choose one of the
1. Corsair CX550 - Bronze
2. Be Quiet Pure Power 11 600W - Gold

Which one do you think it fit my needs and which you prefer?
Thank you.

Be Quiet Pure Power 11 600W looks good, you must have a killer system if you need 550w! 1080ti gfx?
Some people like a little headroom in their PSU, not to mention lower temperatures from a PSU not constantly running at 90%+ of its maximum output.

Do the people who claim you definitely don't need a more powerful PSU think they use more electricity, or that it has to match the calculated output of their components? Efficiency is much better at lower loads.

The Thermaltake 600w psu in my system is doing fine but if I ever had to upgrade it like for a 3090 video card upgrade I could be in for a problem. Because in my pre built CyberTron midtower pc it appears the psu it encased in a metal cover that's riveted to the frame. It's good you can remove yours easily.

I bought the Corsair TX650M Gold a week ago. It looks like a quality product and makes zero noise. As for the durability, time will tell.
Thank you all :)
