Test Setup and Results
I decided to
choose an SLI system, seeing as how two 6800's can cause various power
supplies to crawl. Hopefully, this power supply, which was made
for systems with SLI, will have no problem.
Test System:
Stock
Settings:
Overclocked Settings:
Note: I
noticed the PCI-E connectors did not fit while attempting hook up the SLI
cards. Even the extra PCI-E adaptor for a
Molex connector did not fit. I noticed the bottom center was a different
shape than it was supposed to be, so I broke out a razor and performed
some cosmetic work. I managed to get one to work, but I did not want to
mess with the other one. I ended up using one true PCI-E connector from
the PurePower and one PCI-E adaptor (two Molex's to one PCI-E
connector). Thermaltake did send me a fixed adaptor for the other PCI-E,
but I had already finished installation and testing. However, I applaud Thermaltake for their quick response.
Testing the
power supply is a tedious task. Like cooling products, the "proper"
testing method is long and strenuous. It involves high end
equipment and testing materials that we simply cannot get our hands on.
A simple proper testing method would be to test the wattage draw from
the AC outlet, voltage rail fluctuations, wattage fluctuations under
high operating temperatures, power efficiency, and the power supply's
reaction to low input voltage. But because this site is dedicated more
to overclocking, we'll check for voltage fluctuations in an overclocked
environment. To do this, I utilized a multimeter and positioned
the leads in the respective wires on the ATX connection. For idle
voltage readings, the system was left on the desktop not running any
programs. For full load, the system ran 2 instances of CPU Burn-in,
Prime95 torture test for maximum power consumption, and the Nature test
in 3DMark2001SE. CPU Burn-in is a good program to maximize the CPU
load.
