SilverStone ST50F-P Strider Plus Series 500W Modular Power Supply
Today we’re taking a look at one of SilverStone’s newest additions to their Strider Plus series power supplies, the ST50F-P. Do not confuse this with SilverStone’s ST50F model PSU. Both models are 500W, but the new ST50F-P has a fully modular cable design with a single 34A +12V rail. This one is also a member of the Plus Series, which are said to be more efficient than previous Strider models from SilverStone. This model is 80 PLUS Bronze rated with active PFC . The single 18dBA 120mm fan cools the PSU quietly and efficiently. Although the ST50F-P is the lowest powered model in the Plus Series so far, it is also the smallest (140 mm deep) allowing it to fit easier into smaller cases. 500W is more than enough to power a low to mid-range PC, and the ST50F-P seems ideal for Small Form Factor, Micro-ATX and HTPC builds. Let’s check it out in more detail. For full specs, visit the product page at SilverStone’s website.
The packaging is consistent for models in the Strider Plus line of PSU’s. The box is very nice looking and provides adequate protection for the ST50F-P and it’s accessories.
The ST50F-P comes with case screws, a set of thumb screws, velcro cable wraps, plastic tie straps, power cable, user manual and product guide.
The ST50F-P has a high quality look and feel to it. Like the other models in the series, the cables are covered and fully modular in design to allow for a super clean wiring job. The outside of the PSU has a nice matte finish paint job. The PSU has a plain back with no dedicated power switch or voltage selector. The PSU is auto switching to match the input power that you are using. The blue colored power connector is for the single PCI-E cable. Speaking of cables, the ST50F-P includes the following:
- 1 x 24 / 20-Pin motherboard connector
- 1 x 8 / 4-Pin EPS / ATX 12V connector
- 1 x 8/6-Pin PCIE connector
- 1 x 6-Pin PCIE connector
- 6 x SATA connector
- 3 x 4-Pin Peripheral connector
- 1 x 4-Pin Floppy connector
The heatsinks inside the ST50F-P are not as heavy as the more powerful models in the series, but they provide plenty of cooling potential for the internal parts. The solder points are clean and construction is solid. This model uses a 85 Degree C regulator capacitor which is common for a PSU of this type.
The ST50F-P ran very quiet during testing. The 100% modular cables are great to work with even though they are very stiff at first. The overall build quality is top notch as usual for SilverStone. The lack of a dedicated power switch on this model is missed, as this can be useful in some situations. The voltage tests were within tolerances, though the +3.3V was a bit high on our review model. We are glad to see some high quality PSU’s coming out in a smaller size and lower power range for use in HTPC’s , Home Servers and other small form factor builds.
You really would not need a high powered model for use in systems that are meant to run cool and quiet and typically have low powered video cards or make use of onboard video. The ST50F-P’s smaller dimensions and modular cables can help case airflow as well. The PSU is definitely powerful enough to run a good graphics card (with 50W more power than SilverStone’s SFX Series ST45SF), just make sure you check the minimum power requirements for the card before you buy. The ST50F-P is a nice addition to the Strider Series and we would not have any hesitation recommending it. The MSRP for the ST50F-P is $75 which makes it a good value for a PSU of this quality.
