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 greater than that of the VisionTek 700W, we can test it to the maximum.
Let's start by taking a look at the voltages to see how well this unit did during testing. Starting with the 12V rails, we see 2% regulation from start to finish across both of them. The 12V1 rail showed a total drop of .21V from start to finish and 12V2 showed a total drop of .19V from start to finish. The 5V rail did just as well as it and managed to stay within 2% of specification with a total drop of .08V from start to finish. Moving towards the 3.3V rail, we see that regulation was within 3% with a total voltage drop of .07V.
DC output quality was close to what we expected from the VisionTek 700W Modular unit. We started off seeing 15mV of ripple on the 12V rail during Test 1. As we increased the loads, the ripple had increased to 26mV at a little less than half load. By the time we had the maximum load of 700W we were seeing 49mV of noise.
The VisionTek 700W Modular is rated for 80Plus Bronze efficiency. This means that the power supply must perform at 82%/85%/82% efficiency at 20%/50%/100% loads respectively. As you can see, the VisionTek 700W Modular passed on our bench and wasn't close to failing at any point.
One thing is very clear when taking a deep look at this power supply. VisionTek is no longer geared towards providing products strictly for enthusiasts.
The VisionTek 700W Modular power supply has decent voltage regulation and it slipped a little bit for showing a little bit high during the first test on the 3.3V rail. DC Output Quality started out rather well, but simply didn't impress us as it was loaded down. Finally, the unit is only rated for Bronze efficiency. This just doesn't cut it in the enthusiast world these days.
None of this means that the power supply is a bad unit. It simply means that it isn't meant for enthusiasts. Instead, VisionTek does a fantastic job of nailing an entry level or mainstream power supply.
For a sub-$100 power supply, you get enough power drive multiple GPU's, modular cabling, some cable management and decent quality all the way around. If you're building a PC for the first time, the VisionTek 700W Modular power supply is well worth your consideration and won't hurt your wallet too much.
