Hot Test Results

As it can be seen in the below tables, the SilverStone Strider Titanium offers stunningly low power quality for a PSU of this class. The voltage regulation is great, with an excellent regulation of just 1.1% for the 12V line and very good 2.4%/2.8% for the 3.3V/5V lines respectively. However, the filtering is shockingly lacking, with our instruments recording a maximum voltage ripple of 106 mV on the 12V line, flirting with the 120 mV design limit. The maximum voltage ripple on the 3.3V and 5V lines is 34 mV and 40 mV respectively, for a design limit of 50 mV.

Even though this PSU is rated at 40 °C, we had no problem reaching its maximum power output with a significantly higher ambient temperature. The impact on the conversion efficiency was tiny, with average nominal load (20-100%) efficiency dropping by just 0.7%. The drop was balanced across the entire load range and only slightly greater at maximum load, indicating that the components are not being overly stressed. The maximum efficiency now is 93.3% at 50% load, dropping down to a minimum of 90.2% at maximum load.

The thermal design of the Strider Titanium relies on its high efficiency and abnormally large heatsinks but the high ambient temperature would inevitably force the fan to increase its speed. Nevertheless, the PSU is capable of maintaining comfortable noise levels up to 40-45% load even under such conditions. Beyond that point, the Hong Hua fan does become noisy but, considering the operating conditions, the sound pressure is at reasonable levels. The internal temperatures of the PSU are very reasonable, reaching up to a maximum of 84.5 °C under maximum load.

    I've got this exact PSU for my secondary PC, which is a mini-ITX build. Definitely very quiet and very nice power efficiency!

    What would be the potential savings in a typical 350-400W enthusiast gaming system compared to a Platinum old Gold PSU? Given this price for a 600W, I have a feeling there is very stiff competition when you compare the bottom line (cost of running a machine.)
    And that's completely ignoring the filtering issues, which alone for this price would drive me to the Seasonic 660 Platinum.
  • Freakie - Friday, July 29, 2016 - link

    It would take years of 24/7 use at full 600W load to see any monetary savings by going up one or even two 80 PLUS certification tiers. The only reason to get a Gold/Platinum/Titanium is because they tend to be higher quality and the PSU is the most important part of your computer, so high quality is a good thing. Though this thing's Ripple kinda sucks, I definitely wouldn't buy this unit.

    It's hard to go wrong with Seasonic! I have a 750W Gold Seasonic myself.

    To further expand. When I'm shopping for a power supply, the order of things I look at is: 1) Rated Wattage 2) Ripple 3) How it behaves in a hot environment 4) Cross-load test results 5) How modular (if it all) the unit is 6) The quality (cable gauge), length, and how many cables it comes with (I like to use Full Tower cases, so short cables wont work, and I tend to have a lot of drives) 7) Price and 8) Literally the last thing I look at is the 80 PLUS rating because there is no way in hell I am going to run a power supply at 100% load (I aim for 60%) and 1%-2% efficiency will make virtually no difference in my power bill. The $30 I save from getting Gold instead of Platinum is more than I am going to realistically save on my power bill.

    FYI, with new PSU designs crossload should be irrelevant. Instead of coupled 12 and 5.3/3v supplies modern designs are pure 12V first, and then use DC-DC converters to step down power to the lower voltages as needed.

    I'm with you here, I try to keep my intended load in the 50% range as well. Good for noise, good for the PSU's longevity too.

    Have had motherboards and video cards die in the past because of a poor PSU. A very good quality PSU is a sure thing investment, as they last a very long time anyways.

    I had a bad Seasonic PSU, Seasonic G-Series G-750.
    Cables are too short and very stiff.
  • Alexvrb - Sunday, July 31, 2016 - link

    So was it faulty or just cables too short and stiff? Seasonic units are among the best. I buy mainly Seasonic or FSP. And stiff cables, well if the cables are very high quality (heavier gauge) they're going to be stiffer. Cheaper, thinner cables are more flexible. There is a limit though, and sometimes in a tight case you have to give up some wire thickness. But that doesn't mean stiff cables are a "bad" thing, they just have limitations, pros and cons.

    You know what, just for shits and giggles:

    1% Efficiency difference between Platinum and Titanium
    400 W (your load)
    12 cents average price per kWh electricity in the USA

    .01(1%) x 400(w) = 4(w)
    4(w) x 24 (hrs/day) = 96 (w/day)
    96(w/day) x 365.25(days/year) = 35,064(w/year)
    35,064(w/year) ÷ 1,000 (kWh) = 35.064 (kWh/year)
    35.064 (kWh/year) x .12 ($/kWr) = $4.2 savings per year

    So you save $4.2 per year if you run it at 400W 24/7 a day, all year long which I doubt you're going to do. There is a 3% efficiency difference between Gold and Titanium so you'd save $12.6 a year if you ran it at 400W 24/7 all year long. Efficiency ratings really aren't worth it.

    At release max efficiency items of any type never pay for themselves in reasonable timeframes in areas of average cost; a situation that's been true all the way back to the original 80+ standard.

    You're missing two things, the first is that not everyone pays average rates. Move to Hawaii or Germany and you're paying 35-40c/kwh and the max efficiency models will quickly pay for themselves in 24/7 high load situations and generally break even over system lifespans. Move to somewhere in the developing world where the grid isn't reliable and you frequently need to run a generator to keep the lights on and even light usage will make high efficiency units pay for themselves (gas/diesel generators produce stupidly expensive power). Live somewhere hot enough that you run the AC most of the year and rarely need a heater and the fact that every kWH of power your PC consumes is matched by a second for the AC to dissipate it and your real energy costs can be well above the headline numbers. (Live far enough to the north and using it as a space heater reduces the effective cost of energy.)

    The other factor you're forgetting is that they all become cheaper over time. When they first came out even the baseline 80+ models had a major price premium attached. Today for conventional use the lifetime breakeven point for an enthusiast system is with a Silver/Gold PSU, or Gold/Platinum under near 24/7 use.

    PS A PSU that passes the titanium spec is 2% better than one that passes platinum. This one only got 1% above because it was oversold by Silverstone and didn't meet the spec.
