Our load tests utilize a couple of FAST ATE active load testers, and a variety of other equipment such as an oscilloscope, power conditioner, temperature probe, and a power consumption meter. You can read more about our standard testing approach here.
The tests performed are based around six conceivable setups that are out there, and progressively load down the PSU up to the power supply's limits, or 1000W; whichever comes first. Since our test equipment's limits are higher than that of the Xigmatek Vector P700 700W power supply, we can test it to the maximum.
The above tests represent typical loads that we have measured from various systems, and are meant to give a rough idea of where your computer might fall in line with our tests. Please keep in mind that each system is different, and actual loads can vary greatly; even with similar hardware.
Let's start by taking a look at the voltages, to see how well this unit did during testing. Starting with the 12V1 rail, we see 3% regulation from start to finish, with a total drop of .26V. 12V2 showed very similar results with 3% regulation from start to finish, and a total voltage drop of .28V. The 5V rail managed to stay within 3% of specification, with a total drop of .14V from start to finish. Moving towards the 3.3V rail, we see that regulation was within 3% of specification, with a total voltage drop of .10V.
DC Output quality for the Xigmatek Vector P700 700W was good, and well within specifications. During Test One, we saw 22mV of noise on our scope. When we increased the loads in Test Two, the ripple climbed to 28mV at a little under half load. During Test Four, under a load of 700W, the oscilloscope showed a maximum of 47mV on noise on the 12V rail.
The Xigmatek Vector P700 700W is rated for 80 PLUS Platinum efficiency. This means that the power supply must perform at 90% / 92% / 89% efficiency, at 20% / 50% / 100% loads respectively. As you can see, P700 passed on our bench, and wasn't close to failing at any point.
The Xigmatek Vector P700 700W power supply is the fourth unit that we've reviewed from Xigmatek. Up until this point, we've not found anything exciting about their units, and have had no reason to recommend them either. However, the Vector P700 does not fit in with those, and it most certainly stands out, if nothing more than from the perspective design. Many don't see the need for any style in a power supply; however, they often don't see how many can consider their computer a work of art, nor do they see the care that enthusiasts often put into them.
All of that side, the Vector P700 700W has some good performance numbers. All of the rails for the Vector P700 managed to stay within 3% of specification for the voltage regulation. The DC output quality isn't bad either, as everything was under 50mV. We've had much better results, but considering things aren't out of spec until it reaches 120mV, there is nothing to worry about. Finally, we have the efficiency, and the Vector P700 does a great job achieving this.
As a much as I would love to be able to recommend the Vector P700, I find it relatively hard to do so if you simply can't tell them where to purchase it. Aside from that, the Vector P700 is a good unit, and I have very few negatives to say about the unit. I can only hope that this is the beginning of a new standard for Xigmatek's power supplies. If they can keep up the good work it will be a win for everyone, as there will be more quality units for consumers, along with increased profits for Xigmatek.
