Ultra Products XVS Modular 600W ATX Power Supply
October 27, 2006

Testing:

To test the idle and load voltages of the Ultra Products X-Connect VS, I installed it in a system with the following equipment:

AMD X2 4200 AM2 processor
Asus M2N32-SLI Deluxe
2GB (2x 1024MB) OCZ Special Ops Elite DDR2 800 (PC2 6400)
2x 80GB Hitachi Deskstar SATA 3Gbps hard drive in RAID 0
2x 160GB Seagate 7200.9 SATA 3Gbps hard drive
Memorex DVD/CDRW
10-n-1 Media Card reader
1x eVGA 7900GTO PCIe card SLI
Fans: 2x120mm LED
Cooler Master CoolDrive IV
1x Hauppauge 350 PVR

The idle condition was established by powering the system at default speeds and voltages with no applications running for a period of at least 30 minutes. The load condition was established by running Folding@Home and SiSoft Sandra 2005's Burn-in Wizard for a period of at least 60 minutes. In addition to these stressful applications running, the loaded system was overclocked and overvolted to add more demand to the power supply. The processor was overclocked to 2750 MHz (250x11) and the memory was given 2.1V. These voltages were taken using a Craftsman Auto-Ranging Multimeter (Model 82139), and checked with the Asus Probe II motherboard monitoring tool.

Here you can see both the idle and the load voltages of the Ultra Products XVS power supply. As you can see, during the idle conditions the 12V rail was putting out exactly 12V. The 3.3V and 5V rails were putting out slightly more than the official rating, however they were well within the +/- 5% tolerance. Under the load conditions, each of the rails dropped slightly, with the 12V and 3.3V rails dropping less than 1%, while the 5V rail dropped about 3.5%.


The next chart compares the load voltage readings of the Ultra XVS 600W against three other power supplies; the Enermax Galaxy 1000W, OCZ GameXStream 700W, and Cooler Master iGreen 500W.

As you can see they are all within the generally accepted +/- 5%, with the Ultra XVS being the highest on the 3.3V rail, and the lowest on both the 12V and the 5V rail.
