SilverStone Strider Platinum 1000W & 1200W - Hot Test Results

Enhance is an OEM who does not get concerned with power quality when the figures are good enough and these two units are no exception. The voltage ripple figures are mediocre, with the 3.3V/5V voltage lines flirting with the 50 mV recommended design limit.

The 12V lines hold better, with the ST1000-PT and the ST1200-PT reaching up to 56 mV and 50 mV at maximum load respectively, which is half of the 120 mV recommended design limit but still considerably higher than what the competition nowadays offers. Voltage regulation is good and similar for both units, at about 1% for the 3.3V/5V lines and 1.6% for the 12V line across the nominal load range.

High ambient temperatures have a small but measurable effect on the energy conversion efficiency of the Strider Platinum units. The average conversion efficiency of the two units drops by about 0.6%, to 91.4% and 91.6% for the ST1000-PT and the ST1200-PT respectively, which is very good considering the very large difference in ambient temperature. This hints that the components that the manufacturer is using are capable of maintaining high performance at higher temperatures and/or significantly oversized for their tasks.

Regardless of the high ambient temperature, both units disabled their fans when the load was very low but would immediately speed up their fans when the load increased above just 100 Watts. The two units were not really louder compared to our room temperature tests, meaning that they were already running their fans at maximum speed before, even though the internal temperatures were much lower than the >80°C figures we get inside our hotbox.

    I have a PC Power & Cooling 1200W Silencer Mark III that I purchased 5 years ago. It had already been on the market for a year or 2 at that point. It is also 180mm deep. I don't find the following statement to be terribly compelling, or remarkable, in light of this fact: "Both units are 180 mm deep, which is relatively short for units with that kind of power output, yet certainly longer than what the ATX standard dictates."

    We need more compact SFX PSUs. I understand there is a market for this but it baffles me why I kept using tower cases after having moved to an SFF case which can fit a 1080 ti, 32 gigs of ram, 8700k, two 3.5inch hdd and multiple ssds. All in a case a about 30 the size of my previous case. Reply

    I just really want an SFX-L PSU with two EPS connectors for HEDT boards. I really don't care for the size of regular PSU's anymore regardless of what I'm building and what case. It just seems natural that with everything else miniaturizing, getting better, etc, that PSU's should too. Hell, sometimes the PSU's are half the volume of the rest of what takes up the space in an build. Reply

    PSUs are the only component in a PC that have to use some pretty large components like thumb-sized electrolytic capacitors, transformers, chokes, or even the AC socket (by function and design) while also dissipating up to 100+W.

    Now of course problem might be solved by throwing enough money at it. But would you still like the sticker price?

    There're SFX sized PSUs powerful enough to run dual GPUs, so there's no technical reason they couldn't offer 2xEPS connectors instead.

    I'd suggest @CheapSushi look for a modular design that uses the same 12V connector on the PSU for the EPS and GPU cables; then get 2nd EPS cable for it separately. With full ATX if they use the same PSUside plug or not is hit and miss, so you need to look closely. It should be clear from the markings on the PSU itself though if they're specialized or generic 12V 8 pin sockets.

    Sorry, I somehow read the comment as "I really don't care for the size of [SFX] PSUs anymore". Was wondering how much smaller can they get ant still do the job at a reasonable price. Reply

    There isn't a standard size significantly smaller than SFX. The longer narrower TFX spec might be a better fit for really thin SFF cases, but is only a few percent smaller in internal volume. Below that in size you end up with PicoPSU's and their equivalent which take a 12V (or 19V in some higher power models) external power brick which plugs into a tiny PCB that plugs into the 24pin atx connector and has a handful of other cables branch off from there. Looking at the size of higher powered laptop bricks you probably could make a 1/2 to 1/4 SFX sized internal PSU with a 40/50mm fan for GPUless SFF systems; but with even smaller platforms like NUC eating that segment of the market there probably isn't the demand for it.

    Also look into PSU's like FSP's Twins 500W. Two PSU's, redundant, in the same ATX form factor and then tell me power density can't be improved in SFX and SFX-L. Reply

    One issue is that PSU cables are not standardized. I've seen some SFX PSU's label their port as GPU & CPU. But some other SFX PSU's don't. I've read some people have accidentally screwed up their mobos because of this.

    As for close, there are SFX-L examples already showing what you can do with density. There's already new improvements taking hold with all digital designs and for example Corsair using Gallium Nitride (GaN) MOSFET's. I am 100% prepared to pay more for better SFX and SFX-L PSU's and as they become the norm and companies focus more on them, price would go down regardless. You're assuming just because parts are larger than power per volume can't get any better. That's not true at all. I just don't see the point of ATX anymore in terms of necessity unless going up to 1500W to 2000W where you do need more space. Almost every single consumer rig, gaming rig and most workstations have enough with SFX and SFX-L. Just my issue is that power cables are NOT standardized, the ports aren't standardized and I can't seem to find an SFX-L with 100% assured confidence that I can use a port for a second EPS.
