Testing
Our testing consists of a main PC, and then another two slave PC’s. This is our most extreme testing that we’ve done to a power supply thus far, so if this unit makes it out of the other side, it’ll get my seal of approval.

The main PC has everything powered by the Mach 1, and the slave PC’s have everything bar their motherboard being supplied by the Mach 1.
| Main PC | Slave PC uno | Slave PC dos | |
| Processor | Intel Core 2 Duo E6600 | AMD AM2 X2 3800+ | Intel Pentium 4 Northwood 3.2Ghz |
| Motherboard | MSI P6N-Diamond | Abit AN-M2HD | GA-8IPE1000-G R. 4 |
| RAM | 2GB OCZ FLEX XLC 6400 | 2GB OCZ 6400 | 1GB DDR OCZ 400 |
| GPU | ATI X1900 | Sapphire 2900XT | Sapphire X1950 Pro |
| HDD | 37GB Raptor 80GB SATA |
160GB SATA | 80GB SATA |
| Other | BFG Physx card | Asus Physx card |
All of the PC’s were powered up and then left for 30 minutes to allow the rails to stabilise, and then the motherboard reading of the rails was taken, and backed up by a multimeter from a spare (but hard to find) molex connector.
Then the heat was turned up, and all of the machines had to run full screen (1280×1024) RTHDRIBL, the main PC had a instance of S&M running on both cores, an instance of folding@home and the Physx Cloth demo running with the Space bar held down (shoots balls and gives the Physx card something to sweat about). The slave PC uno also had the Physx Cloth demo running.
This setup was left for another 30 minutes and the rails taken with their highest and lowest recorded. If the setup fails then the power supply can’t take the pressure cap’in.
