Cabling Arrangement

Sparkle Computer makes sure that you have all the connectors that you should need for a power supply in this range. The four 6+2 pin PCI-E connectors make sure that you can adequately feed a pair of GPU's, while the six peripheral cables offer up nine Molex connectors, nine SATA connectors, and two FDD connectors. There are actually more modular cables than you can use at any one time. Sparkle Computer gives you six peripheral cables, but there are only five places to connect them on the front of the power supply.

With a total of five 12V rails, you would expect power distribution to be a little complicated, but Sparkle Computer makes it nice and simple. 12V1 feeds the 24-pin main connector and 12V2 feeds the ATX 4+4 connector. The remaining three rails feed the modular cables. 12V3 provides the power for the SATA and Molex connectors. These three rails are limited at 16A a piece.

For the remaining two rails, the SCC-850AF bumps up the output to 18A each. Each of these rails feed a pair of PCI-E connectors. This means 12V4 goes to one GPU while 12V5 feeds a second one if it is there.

A Look Inside

Popping the cover off of the SCC-850AF reveals a pair of anodized heatsinks cooling the inside of the power supply. We've seen better, but we've also seen much worse here.

Taking a look at the primary capacitors, we see a pair of CapXon aluminum electrolytic caps. These are manufactured in China, while CapXon's headquarters is in Hong Kong.

The secondary side of things shows several Taiwanese Teapo capacitors. It would be nice to see Sparkle Computer step things up here and use high quality Japanese caps throughout the entire design.
