Quick question about putting a PC together (Bitfenix merc alpha)

Reaper 392 · 16 Apr 2013 at 16:39

All the bits of the PC have arrived and putting it together is going just fine except for one thing: nothing is telling us which side of each of the cables that go from the case front panel to the motherboard is positive or negative. this is for the LEDs and power buttons and such. Any help would be appreciated

The case is the Bitfenix merc alpha if that helps

I had this issue and went with - White is negative and a colour is positive! Seemed to work for me, unless the cables are both the same colour.

hmm... wiki is also saying that it is usually red for +ve and black for -ve, so swap black for white and that would tie in with what you did and the HDD LED cable that we've been looking at

White or Black is negative.

Thanks for the help. Once i'd found this review it made things a bunch easier and confirmed the above for bitfenix cases: http://www.tweaknews.net/reviews/bitfenix_shinobi_review/index6.php
