[QUOTE="youdoofus, post: 8666502, member: 664079"] decks will only pull about 10 amperes even at full tilt, hence why they are fused that way. The yellow ones are usually +12v and the black ones ground. Blue and red are usually 3.3 and 5 respectively. A cheap DMM will help you with determining which are which beyond the color coding i provided Get a fuse container and sum them all up on the post in it, find out what amperage the psu can put out and fuse to a hair below that. E.g. if it says itll put out 4 amps, fuse it to 35. The 500 watt psu should put out around 70 or so, but the diagram on the bottom of the unit should tell you what kind of power it is capable of. The big molex is the only one that has any +12v at all or any worth giving a f*ck about. but seriously, get a plank of wood, or something not metallic to mount the PSU, the fuse bock and a ground coupling block to in avoidance of any variables that could cause you issues [/QUOTE]
