I bought a 450W power supply and just bought the rx580 which requires a minimum of 550W... Am I SOL, do I need to replace the power supply.
What psu is it? Is it the Corsair - CXM (2015) 450W from your lists? Then don't worry its a decent psu and plenty for the 2400g and rx580 combo (if that is your configuration).
yeah, the one on the list is the one that I have. ok great, thanks! yes, that is my combo. Why would the specs of the 580 say that it needs 550, if it didn't?
they always list higher then needed because many people use crap psu's that are rated for example as 550W but in reality only give 450W max realistically (or less).
I guess I will keep an eye on the PSU when I start upgrading stuff!
If you add a RX 580 to your saved part list, you get a estimated Power consumption of 294 Watt.

That's a peak gaming with a RX 580. (card only!)
Average gaming should be less than 200 Watts
So, you have ~250 watts left for the remaining build. And that's a lot!
Thats awesome, thank you! Why do the specs for the 580 say to have a min of 550?
Because the manufacturer of that GPU (and that applies to any other GPU manufacturer as well) doesn't know what kind of components your computer will contain.
So for being sure, he suggest a decent sized PSU that would be able to power your computer safely. :)
The only stupid question is the one you didn't ask, and to answer your already answered non-stupid question: it should be fine.
haha love it!
I always buy a PSU for the long haul and the power must also factor in upgradability of hardware - always buy more than you need. As it is though, 450W PSU is plenty for what you have, you are absolutely fine.
great, thank you!
