Charleaux came by this afternoon. Here's what we did:
I put his mobo/cpu, RAM, vid card, and PSU in his case. Connected everything, except I noticed that the PSU only had one 6-pin PCIe connector. In his initial build, he only plugged in the one connector to his XFX 7850 and left the other one alone. This was the one and only problem.
But, I'm stupid, and did not realize that the DVI connection to my spare monitor was loose and not completely screwed in. So we wasted a good bit of time swapping parts and trying to figure out why in the hell nothing would produce video. Wasn't until my own computer wouldn't display video that I actually had the bright idea to check the damn connection.
The PSU works fine, but it's a pretty cheap unstable PSU with really only 450w continuous output, and the 4-pin atx cable is too short. It's a PSU better suited for a low-end microATX build and not a gaming computer. So instead of getting extension cables and a 6-pin adapter and praying the Coolmax can handle the load when he starts gaming later, I sold him a spare raidmax hybrid 630w from a PC I'm parting out, built entire system, did some minor cable management (the raidmax is modular), then we installed windows and all drivers. He left with a complete system, ready to start gaming.
