Been using an external brick for my build the entire time.
since i want to provide info to our community, please note what's being discussed below, is the same exact item [ black color ENP-7660B ] ,and its poster has a good customer service reputation :
That black power supply batch has been scheduled and I think it will be ready in December. They will come without the AC power cord.
They will have the following cable lengths, which will work in the Velka 3, 5, and most other cases that accept Flex ATX power supplies. It's roughly a 40% reduction in cables compared to stock.
24 pin: 1x 250 mm
4+4 pin EPS: 1x 350 mm
6+2 pin VGA: 1x (250 + 50 mm)
4 pin peripheral: none
SATA: 1x (200 + 150 mm)
Since there will only be two SATA connectors, a splitter will need to be used if three or more 2.5" drives are used.
