Silverstone Strider Plus 750In the past week months we have taken a look at some pretty nice power supplies. Many of which are still hanging around to the lab serving various task. Our next power supply looks to join the ranks of this units still staying around. The Strider Plus ST750F-P is Silverstone's first 80Plus Silver power supply.The unit is fully modular something the previous Strider Element was not. These two features along will make the new Strider Plus appealing to the masses.

Introduction to the Silverstone Strider Plus ST75F-P

Silverstone is one of those companies that have succeeded in every area in which they have ventured into. There the cases, power supplies, hard drive enclosures and even case accessories. There isn't many companies that can boost such a claim. One thing that I admire Silverstone for is they have not forgotten what got them to this point. This point being a leader in the case and power supply market. Silverstone has continued to put their all into both of these areas. This is evident by the Fortress FT02 and Raven 2 RV02 case as well as others we will be seeing soon and numerous power supplies that we see popping up each and every year.

Silverstone take on the Strider Plus ST75F-P

The Strider series, as the oldest and most versatile power supply line from SilverStone, has models with myriad of innovative features and rating from 350W all the way up to 1500W. To build on this impressive lineup, SilverStone engineered a new generation of power supplies that combine more important features than ever before. The Strider Plus models, ST75F-P, ST85F-P, and ST1000-P are highly efficient (80 PLUS Silver level), compact enough to fit in nearly any system (160mm depth), have tightly regulated performance of ±3% from a single +12V rail design, and equipped with a quiet but cool 135mm fan. To top these features off, the power supplies also come with 100% modular cables with all the important connectors to support current and future graphics card specifications. For enthusiasts that are looking for a power supply with all the right features to make a high performing and aesthetically pleasing system, any one of the Strider Plus models will fulfill the task with maximum satisfaction.

Closer look

The overall look of the new Strider Plus is nothing that is going to make you jump out of your seat. The unit comes in a matte black paint that is a standard it seems at this point in time. A black power supply goes well in most of the case out there are many of them at black inside. And if your case isn't black chances are your motherboard is. Besides the visual appeal the size of the Strider Plus is a plus. Many high-end power supplies are usually longer measuring about 200mm or longer. The Strider Plus measures just 160mm not including the cabling.

The end of the power supply that you would see from the rear of the case consist of the standard honeycomb ventilation. Missing from the rear panel is the usual red voltage switch that is used to determine 110V and 240V. The Strider Plus distinguish between the two and adjust accordingly. Silverstone state the range is from 90V to 264V.

The Silverstone branding is stamped into the top of the unit. While the left remains plain and uninterrupted. Underneath is a large 135mm cooling fan rated at a minimum 19dBA and max or 36dBA.

The stickered side states all the maximum load numbers of each of the power supply's rails. The one that most individuals will look for is the 12V rail which in this case there is only one. And it has a max load of 60A.

The last side is where all the fun is. As you can tell the Strider Plus is fully modular. Silverstone made it simple to know what cable goes where. The PCIe legs are coded blue while the rest at labeled black. The label at the bottom makes it even easier to select what cables goes where. For added protection Silverstone rate the peak power of the Strider Plus at 800W.

Testing

We know that testing a power supply on a loaded system is not the very best way to do so, but you can not overlook real world testing. Other sites have methods that use thousands of dollars in equipment to provide them greater detail. We have a trusty digital multimeter. Those sites and the methods they use should be the true means of determining how good a power supply really is. However, we feel that showing you how it performs under real world conditions is also a valid measure of its performance.

Testing Hardware:
Motherboard: Gigabyte GA-EP55A-UD6
Processor: Intel Core i7 860 @ 3.8 @ 1.4v
Ram: G-Skill ECO PC12800 4GB Dual-Channel
Video Card: XFX HD 4770
HDD: Seagate 7200.11
Power: Coolermaster GX 750
Case: Sunbeamtech Open-Air Bench
Cooling: Coolermaster 212 Plus
OS: Windows 7 RC
Thermal compound: Arctic Silver 5

Results

During our simple tests we see the Strider performed really well. All rails remained within a safe range.


Conclusion

Honestly, we could not find anything wrong with the new Strider Plus 750 from Silverstone. The main characteristic of the Strider that we saw during our time with it was the stability. Even with our simple array of test we saw very little to no fluctuation in voltage across all three rails. And the 750 watts of supplied power is not slouch either. At this level you will be able to support a nice multi-GPU setup within reason. But one feature many will look for is the modular back-end. If everyone screaming cable management and neatness we can not get enough of modular units.
