PRODUCT PICTORAL AND WALKTHROUGH
For your motherboard, both 8 and 4 pin plugs are included by way of a modular plug. This is an unusual setup. Usually you have both connectors, but Ultra chose instead to allow the plug to split in half. When both plugs are used as a single 8-pin connector, it also runs off of two different 12v rails.
The main power plug is the now-standard convertible 20/24 pin affair, which doesn't require an adapter.
The final three plugs are for the AST feature of the XPro. One for a case fan, one for the CPU fan (two plugs, one power and one monitor) and a PSU fan RPM monitor.
All good specs, so let's fire this baby up and see what she can do.
PRODUCT INSTALLATION AND TESTING
I'll be using my usual test bed, consisting of:
Intel P4 2.8c processor @ 3.2ghz
Chaintech 9CJS motherboard
1x 300gb Maxtor HDD, 2x 200gb Maxtor HDDS
Pioneer DVD burner
M-Audio FireWire 1814 sound
Thermaltake Kandalf LCS liquid cooling system
Testing was performed running Prime95 in a continuous loop, while I monitored voltages with my trusty PSU tester.
Starting voltages were a bit on the high side, with the 12v rails running anywhere from 12.2v to 12.3v. Not excessively high, and well within spec. However, under testing, the voltages did not vary at all, even under heavy load. And, despite the two 80mm fans, the XPro ran virtually silent, only spinning up the fans under the highest load.
Another neat trick is what Ultra calls AST, or AfterSpin Technology. When you use those three cables provided, the PSU will keep your CPU fan and attached case fan spinning for a few minutes after you shut your computer down, thus allowing your components to cool down slowly, instead of just having your cooling solution stop dead after a heavy workout. This is a neat idea, and one that I'd like to see other manufacturers include, if even just for the CPU fan.
All in all, though, the XPro 800 is an impressive product.
