FSP Raider 750-Watt 80 PLUS Bronze Power Supply Review - Test Results and Final Thoughts

FSP's new Raider 750W power supply proves to be quite the value for those seeking enough wattage for a pair of video cards while saving a little coin.

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 RSP Raider 750W 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 voltage regulation stayed within 2% and had a totally voltage drop of .35V. The 5V rail managed to stay within 3% of specification with a total drop of .20V from start to finish. Moving towards the 3.3V rail, we see that regulation was within 4% of specification with a total voltage drop of .16V.

 

DC Output quality for the FSP Raider 750W was okay and well within specification. During Test 1, we saw 27mV of noise on our scope, which was better than we had expected considering the Teapo capacitors. When we increased the loads in Test 3, the ripple climbed to 48mV at around 75% load. During Test 6 under a load of 750W, the oscilloscope showed a maximum of 87mv on noise on the 12Vrail. This isn't impressive, but nowhere near falling out of ATX specifications.

 

The FSP Raider 750W is rated for 80 PLUS 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 Raider 750W passed on our bench and wasn't close to failing at any point.

 

 

Final Thoughts

 

It is very clear right from the start that FSP gears the Raider 750W power supply for those who are conscious about price. Mainstream users typically aren't concerned about having the best performance possible, but rather the best performance for their money. These are the guys that will try to keep to sub-$250 processors, sub-$300 video cards, and sub-$150 power supplies. Many people are often surprised at the performance you cans squeeze out of a computer on a budget and it is because of little jewels like the FSP Raider 750W power supply that we can do so.

 

The unit sacrifices many of the things enthusiasts have demanded come standard with a power supply such as modular cabling, high efficiency, full cable sleeving, and sometimes even cable ties. It even gives up a little bit of build quality with the use of Teapo capacitors and some silence with the utilization of a 120mm fan instead of the more standard 140mm fan we are accustomed to seeing.

 

What FSP doesn't give up on is performance. Many times we have low budget, mid-range wattage power supplies fall out of specifications which can lead to system instability or blown components. The FSP Raider 750W doesn't have the super tight voltages we've seen with the $200 and $300 units that we've been testing as of late, nor is it meant to. It does a great job of utilizing the tolerances built into the ATX specifications.

 

What impressed us the most here though is the efficiency of the unit. Almost every unit we test follows the typical bell curve where voltage starts out low, rises toward peak efficiency at ~50% load, then falls again as it reaches full load. The FSP Raider may be Bronze rated, but it starts off with Gold level efficiency. The best part about this is that this is where the power supply will sit most of the time and give you the best efficiency while checking email, browsing the web and sitting idle.

 

All of this makes the FSP Raider 750W power supply very attractive. Things only get better when you factor in the five year warranty and the super low price of $81. One simply couldn't ask FSP to come up with a better bundle for such a low price, and those on a tight budget would be a fool not to consider the FSP raider 750W in their next build.
