that our Pentium 4 test system draws a lot of power, the Ultra X-Connect
Green UV 500W PSU handled the load very well. The 12V rail only dipped
to 11.99V, which is inconsequential. It's important that the voltages inside the power supply do not fluctuate very
much. If they do then the power supply is delivering bad power to your
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.
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.
testing with a 120W dummy load, the load on the power supply (wattage)
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.

As you can see
here in the Seasonic Load tests, the Ultra X-Connect Green UV 500W is not very
efficient and uses the most electricity of any power supply we've tested recently. What
that means is, it costs more in electricity to use the Ultra X-Connect Green
UV 500W PSU when compared to the other power supplies in this test. Even when
unloaded the Ultra X-Connect Green UV 500W uses the most
Keep in mind that the Ultra X-Connect Green UV 500W can
also deliver more power than the rest of the supplies in this test, so even
though it is not the most efficient, it may still be a better choice for your
complex rig. Also, it's shiny...
buy a cheap power supply, you're putting everything inside your computer at
risk. Does it makes sense to save $50 on a PSU to only have it blow up in the
future and take the rest of your PC with it? Doesn't seem like such a good deal
Believe it or not, the above can happen and will happen. within
my own circle of friends I've seen it three times in the last
two years! Of course that's an extreme case but bad power supplies can also
manifest many other problems from intermittent crashes to data corruption.
Ask around in any computer forum about
power related issues, I'm sure you'll hear some real horror stories.
The Ultra X-Connect Green UV 500W is certainly
one of the most cosmetically innovative power supplies to come around in a long
time. Its modular design means that you won't have to hide those extra power supply
cables behind the motherboard tray or in the 5 1/4" drive bays,
you can simply connect what you need!
UV light the green plastic windows glow a nice neon green while the cables
are cyan in colour. Who says your power supply can't be as pretty as your system?
UltraProducts include enough cables and power plugs for most users; there are eight molex, one
floppy and two Serial ATA power cables as well as the regular
20 pin ATX, ATX12V and Auxiliary lines.
When the Ultra X-Connect Green UV 500W is hooked up to
a system, the rails are rock solid which means system stability shouldn't be
an issue. However, this power supply certainly uses a lot of electricity. The
Ultra X-Connect Green UV 500W uses the most power (idle and at load) of any power
supply we've tested of late and if you pay directly for your electricity, you might
The Ultra X-Connect Green UV 500W is easily the best looking power supply on the market but
this beauty has a pretty steep price in terms of the electricity it can use. Retailing for $154 CDN ($125 US), the PSU is priced
near the middle of its class, but perhaps its best to look past the bling bling and choose another brand which puts its circuitry first.
