Closer Look: Cables and Wiring
Each and every cable on the ULT33185 has received full nylon weave cable sleeving. Each sleeved cable group on the Ultra X-Pro 800W Aluminum PSU ULT33185 is sealed with shrink wrap over either ferrite chokes or a terminating ring. This extra effort provides excellent durability for these wires, and should provide years of worry-free service.
The table below describes the quantity and length for each cable group. For a native cable (non-modular) product, it strikes me as very conservative that Ultra would include such a Spartan amount of connections.
Ultra knows how to design power supply units better than I do, but I have to wonder what they were thinking when they decided on only two PCI-Express connections. This is an SLI certified power supply, but you should expect to have some adapters on hand if you try to power anything bigger than the GeForce 8800 GTX in an SLI set.
Seeing so many dedicated wires for fans is something new to me, but Ultra's ULT33185 800W PSU has three of them. Two of these connectors are specifically designed for the AST feature.
What is AST (After Spin Technology)? After Spin Technology is used to quiet the system and aid in prolonging the life of your components. Connectors for chassis fans are thermostatically controlled; internal fan speeds are reduced when temperatures inside the case are low. PSU, chassis and CPU fan connectors remain spinning several minutes after the PC is powered down allowing the system to gradually cool down after use.
The grommet protecting the native cable group at the chassis entry point is very heavy duty, and does an excellent job of maintaining the cables and sleeves. The Ultra X-Pro 800W PSU really is shaping up to become a very rugged power supply, which is probably very well suited for harsh environments. System builders for the niche markets should see some potential here, especially in the automotive diagnostics and outdoor terminal industries which incorporate PC components; i.e. SMOG machines.
By remaining non-modular with the cables and wiring, the Ultra X-Pro 800W PSU can become a mess once it is installed into the computer chassis. The image below is an excellent example of the many cables and connections the Ultra X-Pro 800W Aluminum PSU ULT33185 offers, but it also depicts the numerous cable groups which you will have to find a home for.
Ultra has designed the PCI-Express connectors on the Ultra X-Pro 800W Aluminum PSU ULT33185 1200W PSU with only the 6-pin connections. Which means that future products using the 8-pin design will require an adapter. One of the biggest shortcomings I have found thus far is the scalability of this product to work with emerging technology components.
