need help choosing between
Thermaltake is better all the way. But they are both weird choices. Where are you buying?
The SeaSonic has better ripple suppression and voltage regulation
The Thermaltake uses DC-DC conversion on the secondary side, while Seasonic is a 7 year old design with group regulation. It's ancient in comparison, not really suitable for modern computers.
does the rgb really worth it? kinda pointless because no rgb header to mobo for syncing whole system. it in similar price on my local reseller. this is the last part of my build so kinda tight on budget.
What is your build and what are the other power supplies in your reseller's offer?
