Over the last three years I've reviewed three different SilverStone power supplies: the Strider Plus 600, Strider Gold 750 and the Strider Gold 750 Evo. With each successive model, power handling increased and efficiency improved, but for this review we've come full circle back to a 600-class unit. Despite its somewhat smallish power rating, the Strider Gold 650 packs an impressive amount of capacity into a tiny small form factor. At only 140mm deep, the ST65F-G is highly compact yet still manages to offer fully modular cables and capable power handling with Gold class 80Plus efficiency. SilverStone's PP05 short cable kit is available for those looking to incorporate the 650 into some tight spaces.
The ST65F-G is Haswell ready and SilverStone supports up to dual GTX 770 or HD7970 SLI / Crossfire graphics configurations on the 650, with its single 54A continuous +12V line. It certainly had no problems powering our Haswell system, which registered the lowest power draw at the outlet of any high-end desktop we've ever tested. In fact, for powering a system using on-die graphics of the latest Haswell and Richland processors, the 650 is really overkill. You could easily get away with using its smaller sibling the ST55F-G and still retain that excellent Gold class efficiency.
I found the ST65F-G available at several places online for only $115 after a $10 rebate. That puts it right in the same ballpark as some other highly capable units like the Thermaltake TP-650P and Seasonic SSR-650RM. If you hadn't previously considered a 600-class power supply out of concern of being underpowered, the SilverStone Strider Gold 650 is worth another look.
OCIA.net awards the SilverStone Strider Gold 650 our Gold Seal of Approval.
