Conclusion
The Phnateks AMP 750 is the first power supply we have seen here at TheFPSReview from Phanteks. However, Phanteks has been marketing power supplies for a while now even if they are not their core business, or what many users are used to thinking of when they see the Phanteks name. However, with the AMP 750, we have here today Phanteks has selected a strong OEM partner and they have kept the expectations modest as this unit is not a top of the line product. So, the chances for success seem to be rather high. The question is; do chances translate into reality? Let’s see.
Build Quality
Today’s Phanteks AMP 750 starts things off with a build quality that is very good for its market position. The exterior represents a somewhat restrained approached but it is still a well-branded product. This is in addition to the fact that we get good cables and a nice finish. The integration is very clean as we often see from Seasonic. The component selection features Nippon Chemi-con, Nichicon, and Rubycon standard electrolytics paired with FPCAP and Chemi-con solid capacitors. There is also an FDB fan today which will be of interest to our quiet cooling enthusiasts out there. The documentation with this unit is a disaster but the 10-year warranty is an excellent length.
Load Testing
Today’s Phanteks AMP 750 started off testing in very nice shape. We saw voltage regulation of up to 0.14v on the 12v rail, 0.06v on the 5v rail, and 0.06v on the 3.3v rail. In addition to that, we saw efficiency that ranged from 87.35% to 90.76% efficient at 120v AC input and 85.00% to 89.58% at 100v AC input. These numbers would be good to very good for any unit. However, this unit is a more mainstream offering, so these values definitely get a bit of a bump because of the more value nature of this product. Given the marketing that came with this unit, we hoped for this outcome today, but it is nice to see the marketing come through in the testing today. Well, at least in this aspect of testing anyway.
When we look at the Transient Load Tests results for the Phanteks AMP 750, we see that the results are excellent. When directly loaded, the 12v rail showed a peak change of ~280mV, and the 5v rail had a peak change of ~50mV. During the 12v load, the unloaded 5v rail saw a peak change of ~45mV. In absolute terms, these results are excellent, but in relative terms, these numbers are even better! This is a more mainstream offering and it is “just” 750W so these Transient Loads are nothing to sneeze at. Hell, we see 1200W monsters that post worse numbers than this!
DC Output Quality
The DC Output Quality results for the Phanteks AMP 750W were good with a bit of odd mixed in just for fun. To start off, we saw peak ripple/noise values of just ~35mV of ripple/noise on the 12v rail, ~15mV on the 5v rail, and ~15mV on the 3.3v rail during our regular load tests. These values are well within specification limits and that means, at a minimum, good in absolute terms. In relative terms, these results are probably pushing excellent. However, during the Torture Test, we did see higher values which puts a cap on how great these results can be. That said, this unit did pass so there is no substantial concern here today with that cap.
Noise
Today’s Phanteks AMP 750 is not a tiny capacity unit, but it is based on a platform that we have seen decent to good results from when it comes to noise output before. On top of that, this unit also features a FDB fan, which quiet cooling enthusiasts just go ga-ga over, and it is coupled with a hybrid fan controller option. While we tested the unit with hybrid mode off, it was not until the 100% load test that it was apparent that the unit was adding noise to our load testing environment. At all other load levels, the fan was very mild. So, this unit seems to be very nicely behaved and should be a very good option for folks looking for a quiet mainstream product offering.
Final Points
The Phanteks AMP 750 is a very good unit with high performance and high efficiency in the mainstream marketplace. The AMP 750 gave us very good/excellent build quality, very good/excellent voltage regulation, good* DC Output Quality, and excellent Transient Load results while also being very quiet. Certainly, there is a bit of caveat on the DC Output Quality there but, in the end, the unit was still in specification and great during the normal load tests. So, what is unit going to cost us?
Today, we find that the listed retail price according to Phanteks is $109.99. In the market, it is currently harder to come by, like all units, and the best price we can find today is $132.99 from a company that we have not done business with before. However, if you buy through the Google store you do get Google’s guarantee. So, we will go with that price of $132.99. Now, that is a bit of a tough price to swallow since it is coming in above the MSRP. However, it seems every power supply is these days. Well, that is, if you can find them in stock. So, we can not fault Phanteks for that. Thus, this unit is going to be a solid value at its normal MSRP and still one today simply because the market is all out of whack. Users looking for a solid mainstream power supply with a long warranty need not look any farther than the Phanteks AMP 750.
