Seasonic Load test and conclusion

Power Jitter Observations

Voltage jitter is read by accessing the power options displayed in the motherboard BIOS, with the system obviously in an unloaded state. All voltages were read from the Motherboard BIOS of a DFI LANParty NF4 SLI/DR .

PC Power and Cooling Turbo-Cool 510 SLI

Listed Voltages Lower Voltage Upper Voltage Jitter
+3.3V 3.25V 3.27v 0.02v
+5.0V 4.99v 5.02v 0.03v
+12V 12.02V 12.09V 0.07v
-12V -12.12V -12.12V 0.00v
-5.0V -5.01v -5.01v 0.00v
+5.0Vsb 5.05v 5.05v 0.00v

In the voltage jitter observations, the Turbo-Cool 510 Express/SLI showed extremely steady voltages. The 0.07 jitter from the +12V rail was a little larger than we'd normally like to see, but since the voltage numbers are so accurate to begin with, this is pretty much irrelevant. Note the rock steady +5V rail.

Seasonic Load Tests Source: Seasonic

When looking at the Seasonic Power Supply test results we see two values, wattage and volt-amps. Since it might not be clear what they measure, here's a brief overview.

The volt-amp (VA) value is how much real power is being consumed by the power supply being tested to provide the wattage (W) value. The higher the VA value is, the more electricity is being used by the power supply. Because no electrical device is 100% efficient, there will always be some loss when converting AC to DC. The closer the volt-amps and wattage figures are to each other, the more efficient a power supply is. This is called the Power Factor: wattage / volt-amps = PF.

Since we're testing with a 120W dummy load, the load on the power supply (W) should be as close to this figure as possible. Anything above this load in apparent power describes the overhead and wasted energy (given off as heat) for the particular power supply being tested.

For the unloaded tests, the Wattage and Volt-Amp figures should be as close as possible to one another. The lower the figures are, the less power is being used. For the % Efficiency values, 100% is the best, and 50% or less is quite poor.

As the only Active Power-Factor Correcting (A-PFC) power supply in the test results besides the Seasonic SuperTornado and S12-430, the PC Power and Cooling Turbo-Cool 510 Express/SLI turns in an excellent power efficiency from the point of view of power conversion. Active PFC really does make a huge difference in the amount of energy wasted by your computer, and consequently how much you end up paying in power bills later on.

In terms of actual power consumption though, the Turbo-Cool 510 Express/SLI is a bit of a hog. Its unloaded power consumption was 29W, and loaded power consumption was slightly higher than the rest of the field as well at 200W. It's not going to bankrupt you, but its worth noting that this PSU is better turned off when you leave for summer vacation.

Stable as a rock, heavy on the power

Once the heavyweight PC Power and Cooling Turbo-Cool 510 Express/SLI was pulled out of its packaging, we were expecting good things from it and it did not disappoint.

This power supply proved to be extremely solid and accurate in terms of the voltage it delivered across its various rails. As one of only four PSU's specifically approved by nVidia for use with SLI videocard systems, you'd expect solid power performance and the Turbo-Cool 510 Express/SLI delivers.

The PC Power and Cooling Turbo-Cool 510 Express/SLI is completely nondescript in appearance, though its nicely wrapped cables and the 14AWG duty AC power cable it ships with are both good indicators of the build quality PC Power and Cooling has put into this unit.

In terms of power use, the Turbo-Cool 510 Express/SLI takes a bit more for itself than most of the PSUs we've tested, especially when not under load. In light of its Active-PFC inspired 99.0% power efficiency and excellent voltage stability though, voltage regulating potentiometers for fine adjustments in overclocked settings, and twin 6-pin SLI power cables, that one small disparity is easily forgiven.

PC Power and Cooling offers a five year warranty on the Turbo-Cool 510 Express/SLI. Considering that power supplies are the most common cause of computer failure, this indicates a comforting degree of confidence in the product by the manufacturer.

At a price of $265CDN ($215 US) for the 510 Watt model, the PC Power and Cooling Turbo-Cool 510 Express/SLI power supply is anything but cheap. For hardcore overclockers and SLI enthusiasts, or anyone investing serious amounts of money into their computer hardware, the price of the Turbo-Cool 510 is well worth it for the performance delivered.
