SilverStone is one of the most reputable PC chassis and PSU manufacturers worldwide. The company is no stranger to AnandTech as we reviewed a plethora of their products during the years. However, it has been a long time since we reviewed one of their high-end power supply units; as a matter of fact, ever since the review of the Zeus 1200W PSU seven years ago, we have only been reviewing their least powerful PSU models. As a result, SilverStone supplied us with their currently most powerful model - the Strider Gold S 1500W (ST1500-GS).

SilverStone has some very interesting things to say about the Strider Gold S 1500W PSU. These include the fully modular design, 80Plus Gold certified, compact design, strict performance standards and a frightening price tag of $350. However, what is even more terrifying is that it has been rated for continuous operation at 40°C, not 50°C like the majority of manufacturers do for their high-end models. This is not in any way illegitimate as this is the normal rating for the operating temperature of consumer PSUs and other companies do rate some of their units at 40°C as well. However, a $350 PSU rated at 40°C comes with an element of shock, especially when considering our recent review units which have also had a 40ºC limit.

Packaging and Bundle

The packaging of the Strider Gold S 1500W PSU is modest and sturdy, with a wealth of information to be found on the sides and the back of the box. The artwork is dark and very simple, as SilverStone always prefers focusing their efforts on beautifying the product itself. Inside the box, the PSU is protected very well within a polyethylene foam shell and a nylon bag.

SilverStone provides a good bundle with the ST1500-GS, consisting of a good manual, an AC power cable, a nylon fan filter guard, a few cable ties, four long cable straps and two sets of black screws (one normal set and one set of thumbscrews). The fan filter is magnetic but it can also be screwed in place if necessary.

We should note that the AC power cable included this PSU is not a standard C13 plug but a C19 plug, as shown on the unit below.

The ST1500-GS is a fully modular PSU, down to the ATX 24-pin cable. Every cable is a sleeveless, flat "ribbon" type, made using all black wires and connectors. This includes the ATX cable and the CPU/PCI-E 12V connectors. Only the blue connectors at the PSU side of the PCI Express power cables stand out against the vantablack-like design. The ATX cable also has a 4-pin voltage sensing connector that needs to be connected to the PSU separately.

    The Powercolor Devil13 (2x R9 290X) can pull loads in excess of 450W (and clear excess of the ATX specifications), so a crossfire setup with two of those and an AMD FX-9590 can exceed 1100W on CPU & GPU alone. Add Memory and a bunch of Harddrives, and maybe a dozen electronic gadgets on the USB ports, and you can use the 1500kW in extreme load cases.

    Not saying you should, an Intel 2011-3 system with two Titan X will give you more gaming power in barely over 600W peak power consumption.

    One overclocked 290X hit 400 watts in Tom's testing. It was only a very brief spike, but those spikes should be factored in. So, three of those plus a 9590 and you're talking 1465 watts.

    Handy review for the three or four that might need this.

    I would appreciate a different direction from the psu makers.
    With today's low power systems idling at 15-30W it would make more sense to focus on low load efficiency and smaller total power output, while maintaining the same quality components found in higher powered models.

    That describes most PSUs actually sold. The one in this review is strictly for e-peen who devote far too much of their income to their PCs.

    People always overbuild their PSU's. They go for watts over quality. It's a consumer misunderstanding of power requirements and efficiency.

    Most OEM systems come with ~200-watt PSU's these days. Even high-end workstations like HP Z and Dell Precisions have 280-watt PSU's.

    My Xeon workstation with a GTX970 has a 400-watt PSU and my Overclocked i7 SLI gaming PC has a 550-watt PSU, and both have headroom (peak draw from the wall for each under OCCT\furmark is 363-watts and 509-watts.)

    I'm not saying a product like this has no reason to exist, but let's just say it's for "the 1%."

    The most recent 80+ spec, Titantium does focus on low load efficiency by requiring 90% efficiency at a 10% load. For all but the most severe cases of mis-matched system power and PSU size this will bring idle loads for systems with dGPUs into the high efficiency operating range.

    If OEMs actually refresh their low power models the same should be possible for IGP only boxes; but the negligible number of 80+ units of any size in that range make me suspect we'll be waiting a while for that to happen. Accommodating Haswell's deeper sleep states might push more of them to refresh their designs over the next year or two; but only 9/23 haswell compatable <400W models on newegg are gold certified (none are platinum). However the additional 432 non-haswell certified PSUs in that power bracket make it clear that this is going to be a very slow process. TBH for those systems actual amounts of power saved are small enough that it's only at very high power prices that a high efficiency PSU will pay for itself over a reasonable time horizon. Unless forced by regulators, I wouldn't hold my breath for any significant movement in the small PSU segment.

    Fools and their money hey... there are some people who purchase merely for the wattage number on the PSU. Says nothing of the quality and even less of the actual requirement. I wonder if this was a hangover from the days where a cheap 300W POS, er PSU would struggle to output 200W without exploding. I peaked 350 watts with a pretty hefty system (GTX 680, overclocked i5-3570K, 2 HDDs). That's 250 watts of headroom from my "low end" 600W PSU. Things might be different in AMD world but Intel/NVIDIA just keep getting more and more PPW.
  • reininop - Tuesday, April 7, 2015 - link

    I didn't read the full article, so I may be restating, but for all the people asking what you need 1500W for, the efficiency of these usually peaks at about 50 - 70% of rated power if I remember right. While even a 750 W pull is a pretty hefty system, there might be a slight market for the eco-conscious tech enthusiast...

    Okay, so maybe the audience is still only about 4 people.
  • DanNeely - Tuesday, April 7, 2015 - link

    You obviously didn't read much if any of the article: You're way off.

    This is an 80+ gold unit which means that it needs to be >88% efficiency from 20-100% of full load (@220v, >87% at 110). It managed >90, and peaked at 92% efficient at a 50% load.

    Sub 70% efficient power supplies are designs from a decade or more ago; and are long gone from the market (possibly excepting some of the sketchiest no-name models); bargain basement 80+ units are widely available now.

    Lastly, the power rating is output power, not input. A hypothetical 50% efficient 1500W PSU would still output 1500W of power; it would however draw 3000W at the intake.
