Installation / Testing

None of the 20+4pin ATX, 4+4pin ATX/EPS or 6+2pin PCI-e connectors snap or latch together for quick installation, although the ATX and PCI-e do have tabs on the smaller sections to help hold them in place, and the ATX/EPS feature clips on both halves.

I'm installing the SilverStone Strider Plus 600W power supply with the following hardware:

AMD Phenom II 1090T X6 BE
Kingwin XT-1264
2x2Gb Crucial Ballistix Tracer DDR3-1600
Diamond Radeon HD5850
128Gb Crucial C300 RealSSD
Icy Dock 2" Adapter
1Tb WD Caviar Black
Optiarc 24x DVD+/-RW
Cooler Master HAF 932 AMD Edition

Using a Kill-A-Watt meter I measured total system load at the AC outlet to be just 83W at idle, and up to 447W with the OCCT power supply test utility, which maximizes both CPU and GPU load. Graphed as a percentage of power supply capacity, the system is utilizing less than 15% at idle and around 75% when fully loaded. SilverStone rates the Strider Plus 600W for a full, continuous 600W load at 40 C, and supplies four PCI-e cables for multi-GPU operation. In fact, their official GPU support list claims the ST60F-P is capable of running dual GTX 260 or ATI HD5850, however as illustrated above, when coupled with a high-end processor, that could potentially put the system load at or near the maximum rating. If you're planning to use the 600W for SLI or CrossFireX you will want to consider your system component selections carefully.

During testing I also took voltage readings using my Fluke multimeter at the back of the connector, and graphed the results above. All of the rails did measure a slight voltage drop going from idle to load, however this was determined to be 1% or less of their rating. While under load conditions, voltages fluctuated by as much as +/-.04v, in particular the +3.3V measured only 3.29V at one point, and the +12V at the PCI-e cables registered as low as 11.98V in some cases. Although this is not a big concern, it's not quite as stable as some other power supplies we've tested.

The Strider Plus 600W is certified at the 80Plus Bronze level for power efficiency, which means it exceeds 82/85/82% at 20/50/100% load. In fact, in independent testing, it reached 85/87/83% efficiency, nearly placing it in the Silver category but for it's slightly worse performance under full load. The 750W version of this power supply that Charles reviewed a few months ago does manage to net the Silver. If you're thinking Green, and are conscious about the wattage that your computer uses, you'll want to pay attention to these ratings because just a few percentage points can add up to some significant savings when it comes time to pay the electric bill.

To compare just how much difference a newer, more efficient power supply can make, I replaced the SilverStone Decathlon 750W power supply in my network file server with the Strider Plus 600W. The DA750 is similar to the 700W version we reviewed two years ago, and although SilverStone rates the Decathlon series as having ">80% efficiency" there is no 80Plus certification testing to back that up.

My server is comprised of the following hardware:

AMD Sempron 140
Biostar TA790GX A3+
2x1Gb Crucial Ballistix Tracer DDR3-1333
Onboard HD3300
74Gb WD Raptor
2x320Gb Seagate 7200.10 RAID1
NEC 16x DVD+/-RW
Mountain Mods H2gO

As you can see from the graph, the system uses 12W less at idle with the Strider Plus 600W compared to the Decathlon 750W, and 14W less under "load". Since this is only a single-core processor system, using onboard graphics, the loaded wattage draw is not much more than the idle. But what is important to note is that the Strider Plus 600W uses 13% less energy than the older Decathlon 750W even when it's just sitting there doing nothing, which is what this system does pretty much 24/7/365.

Let's wrap things up with some final thoughts and conclusion.
