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 equal to that of the Cooler Master V1000 1000W 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 12V rail, we see 2% regulation from start to finish with a total drop of .14V. The 5V rail managed to stay within 2% of specification with a total drop of .05V from start to finish. Moving towards the 3.3V rail, we see that regulation was within 2% of specification with a total voltage drop of .05V.
DC Output quality for the Cooler Master V1000 was great and well within specifications. During Test 1, we saw 13mV of noise on our scope. When we increased the loads in Test 3, the ripple climbed to 21mV at around half load. During Test 5 under a load of 1000W, the oscilloscope showed a maximum of 30mV on noise on the 12V rail.
The Cooler Master V1000 1000W is rated for 80 PLUS Gold efficiency. This means that the power supply must perform at 87%/90%/87% efficiency at 20%/50%/100% loads respectively. As you can see, the Cooler Master V1000 passed on our bench, and wasn't close to failing at any point. It was in fact a very efficient unit, staying very close to Platinum levels of efficiency throughout most of the tests.
It is very apparent that Cooler Master has made a wise move in choosing to partner with Seasonic for the design and production of the new V series power supplies. Seasonic has been an industry leader in the power supply market for decades and leveraging their experience and quality is never a poor choice. The result of this collaboration represents the some of the best that both companies have to offer.
Just from a performance standpoint, it is clear that the V1000 will be a winner for years to come. Voltage regulation is within 2% across all rails, and it wasn't far from the 1% mark on the 12V and 5V rails. DC output quality is also great as the unit shows relatively low noise on the 12V rail throughout all of our tests. The efficiency results are also great as the results are darn near on par with what we expect from a Platinum rated unit, not a Gold one. I'm actually surprised that there wasn't a tiny bit more work put into this unit to raise the efficiency a bit just to up the rating, but those reading reviews will know that the difference between this unit and a Platinum unit is so subtle that they will never know the difference.
Rounding things out for this unit are the price tag and warranty. At an MSRP of $209, the V1000 sits where it should appropriately right from launch. There are others with a tiny bit better performance or features, but they are all priced above this unit, and there are others that are a tad worse priced just below this unit. Aside from the perfect positioning for launch, that means this unit will drop in price a bit in 3-6 months a be a steal for anyone in the market for a 1000W power supply.
Mark my words, the V1000 is going to be a power supply that will be a great performer both now and years to come. Perhaps it will even become one of the models that everyone knows about as it is great on every level, not just one.
