SilverStone has a long tradition of offering small PSUs, and the new ST1500-GS is an excellent example of this, achieving an impressive 646 watt per liter power density score.

Ripple Measurements

To learn how we measure ripple, please click here.

The following table includes the ripple levels we measured on the rails of the ST1500-GS unit. The limits, according to the ATX specification, are 120mV (+12V) and 50mV (5V, 3.3V and 5VSB).

Ripple suppression was adequate on the +12V, 5V and 3.3V rails, but it definitely wasn't among the best in this category. The performance of the high-capacity Super Flower platforms in this and other sections made us very picky when it comes to ripple performance. On the 5VSB rail ripple was at high levels, especially during the higher load tests. 

Ripple Oscilloscope Screenshots

The following oscilloscope screenshots illustrate the AC ripple and noise registered on the main rails (+12V, 5V, 3.3V and 5VSB). The bigger the fluctuations on the screen, the bigger the ripple/noise. We set 0.01V/Div (each vertical division/box equals 0.01V) as the standard for all measurements.

    Too bad for this model, but I can't wait to see what this watt-per-litre ratio does for SFX!

    I would not be that bothered by the lack of a physical switch: most people plug their PC in a power strip, surge protector or UPS and these usually have their own switch.

    Someone bothered enough by the 5VSB power draw to bend under their desk or reach over wherever the switch ends up being in their setup to switch the PSU off should be similarly bothered by the standby power draw of their displays, USB hub, external HDDs and other devices enough to want to turn them all off as well. The simplest way to achieve that is plugging everything into one power strip and turning everything on/off at once from there.

    Also, leaving the 5VSB supply on 24/7 costs less than $0.20/year in power. How much does a replacement CR2032 battery cost and how many power-off hours does it last? It might be cheaper to leave the 5VSB power on.

    The only time where I cut power completely off is during power outages to spare my components all the surges and sags over the first few seconds after power comes back on.

    I don't think I'll ever have a use personally for a 1500w PC, but if I need that kind of juice this is exactly what I'd be looking at.

    Not the best option, clearly, but what you'd expect from a Gold rated PSU and solid build integrity that should last a long time. I would test this PSU without a fan or with a low noise Noctua fan.

    While I agree with you for the most part, I have had a set of Creative Labs speakers for 10 years that have a remote that use a CR2032 and it is still good with plenty of use and standby time.

    I do agree though that it is annoying not to have the switch on the PSU. Of course I look at it from a repair point of view where having that option is faster than pulling the plug every time I would need to test something.

    A good battery-operated remote tries very hard to minimize leakage and standby current while a computer RTC which may expect to have 5VSB power available all the time except during power outages has little reason to go to extremes to minimize battery power draw.

    My old Sears TV's remote drains 4xAA in less than a year.

    In my experience the power supply switch is primarily a convenience, used to ensure a power supply and connected system is de-energized when servicing the computer; inserting or removing components, such as swapping video cards, installing storage drives, etc. This is because the 5VSB (5 volt stand-by) is supplied by the motherboard to PCI and PCI express slots, as well as obviously flowing across a few of the PCB traces, so it is recommended to disconnect power, including stand-by voltage to prevent accidents.

    Errrm, there's a typo in the article. Look at page 3, the same paragraph has been repeated :)

    While I don't bother about in-build power switches so much since I always switch off/on via the main wall socket anyway, but it's a nice addition to cater to everyone's need, which is especially expected in these kind of high-wattage PSUs. When we talk about 1.5kW, compromise is what people would reluctantly want.

    Judging by the actual results of the PSU, I think "80+ Silver" should've fitted nicely with it. That way, it wouldn't defame "80+ Gold" Standard :P What I mean actually is, it's barely holding on to the 80+ gold standard. While it doesn't actually translate to significant deal breaker, it's somewhat disappointing to see 550W-approved things in this 1.5kW unit.

    However, the PCB neatness certainly gets my thumbs up. Among the most units I've seen from different distributors and OEMs, this one looks very neat (apart from the gooey use of solder there, Ewwww!), components are arranged very nicely, and there aren't any glue (or whatever you wanna say them) oozing out from or underneath heatsinks and FETs.
