The first one has a combined current of 36 A on the +12V rails, power o/p on the same is 432 W
The second one gives 40 A total on +12V, but a power of only 400W. It's less efficient.
Also the first one seems to have more power connectors.
So I'd say the first one is the best bet (assuming both are equally priced)
First one is a 64 eura
Second is a 58 eura in Croatia.
Im for first one, just becouse can produce 40A and have 6 Sata, but have one less power connector...
