Sentey Golden Steel Power GSP850-SM 850 Watt Power Supply Review

Test Results

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 Sentey Golden Steel Power 850W power supply, we can test it to the maximum.




As we expected, the GSP850-SM performed quite well through all of our tests. Voltage regulation was almost identical to that of the other Golden Green based units that we have reviewed here at TweakTown; perhaps a tad bit better. It would be nice to see the voltage regulation be a little tighter at lower loads as that is more than likely where the largest performance gain could be made for this power supply design. That said, everything is well inside specifications for the voltages on the GSP850-SM.


Noise measured on the 12V rail is what we would consider good. While it certainly isn't the best that we have seen, it is far from the worst and well within ATX specifications. Ripple started out measuring 21mV peak to peak on the 12V rail and as the loads increased on the power supply, so did the noise that we could see. Eventually the power supply ended up showing us a maximum of 49mV peak to peak under full load.


Efficiency for the Sentey Golden Steel Power 850W power supply is excellent and right where it should be. As an 80Plus Gold rated power supply, the unit should be 87%, 90%, and 87% efficiency at 20%, 50%, and 100% loads respectively. The GSP850-SM excels at meeting these requirements and is well deserving of the rating.


Final Thoughts


As this is the third unit that we have had on our test bench here at TweakTown based off of the Golden Green power supply, it is safe to say that any power supply based off this design is going to be a winner so long as it isn't overpriced. Just as these units have done in the past, the Sentey Golden Steel Power 850W power supply performs quite well. Voltage regulations are within 3%, efficiency is excellent and ripple on the 12V rail is good. Sentey has even gone above what its competitors offer on the Golden Green based power supplies be giving a seven year warranty over the usual five.


Normally there is something negative to say here, but we are struggling to find something. What it comes down to is that we have a company that most have never heard of rebranding a power supply of proven quality, upping the warranty on it, and selling it at a fantastic price of $5 more than their competitors who use a shorter warranty. That extra $5 is well spent for the peace of mind the additional two years of warranty bring and the Sentey GSP850SM is well deserving of your money if it fits your build.
