Is a 550W PSU Good for a 500W Maximum Power Usage?

Hello, I was just wondering if the ~50W difference between the PSU (550W) and the max power usage (496W) is good enough.

If it's not, then I have another question: There's this 600W PSU, which I was originally going to get, but I was told by others that it's not very efficient/powerful/durable/etc. and that the above 80+ Gold PSU is a better option. Is this true?

Thanks in advance for any help. I really appreciate it.

That's a bit tight for my liking and personally would be more comfortable with a 600w+ psu. The 750w version here would probably be better for you in the long run.

Ahh, somehow I never even found that PSU! Heck, 750W and an 80+ Gold rating for $60... that's a steal! Thank you very much!

Check the power calculators, they should give you a good estimate of power requirements. I'd like to leave a 25-50 W overhead on top of whatever their already factored overhead is.

From a glance, I'd say a 550W PSU is a little low for your build, even assuming you don't plan on crossfire in the future. You might consider going up to 600 - 650 W. 'Don't go by brand names' seems to be the general consensus around here, just read reviews and compare specifications.

Ah, yeah, I actually already ordered my build with a 750W PSU, but thank you for the help anyways!
