Specifications and Packaging


The SilverStone Platinum Series 850W power supply is rated for a combined, continuous output power of 850 watts at 40°C. The PSU incorporates a single +12V rail that can deliver up to 70.9A (850W).  The PSU includes universal AC line input (automatically adjusts the AC line voltage) and active PFC, which makes the unit more environmentally friendly to the local power grid.

Did SilverStone send you the PSU for review, or did you request it? If the latter, I'd say you missed an opportunity by going for the highest capacity one of the lineup. The 550W is far more interesting, as it's one of the lowest capacity Platinum units out there, and a perfect fit for today's high end GPUs.

The 850W model was sent to us for review as SilverStone wanted to showcase the highest power in the smallest package. However, we may follow up with a review of the 550W unit. Its always nice to have the opportunity to check out more than one unit in a new series.

That would be great, hope you are able to get one in for review.

Of course I see SilverStone's point (850W Platinum in a smaller package than most 5-600W units is not bad at all), but high powered PSUs are less and less relevant in today's PC builds. 3,5" HDDs are slowly dying, multi-GPU was never really a big thing, and is quickly falling to the wayside, and >95W CPUs with actual performance to match are reserved for those with too much money to spend (although Zen might change that).

SilverStone should be lauded as one of the first PSU makers to make <700W Platinum units, but we still had a long way to go. I'm still waiting for something compact, modular and high efficiency in the 3-400W range. You can barely get 80+ Gold below 500W today.

It's *possible* DX12 may cause a resurgence in multi-GPU setups.. But agreed we need more gold/platinum small units.

My home (VM) server is running well with a Seasonic 360W 80plus Gold..

Sure, it's possible, but still highly unlikely. After all, DX12 multi-GPU support is as reliant on developer support as DX11 ever was, just easier to implement (just not as reliant on driver profiles). And as always, it works on a game-to-game basis, with many lacking support. Not to mention that most PC gamers buy a single ~$200 GPU, and can't afford multiple. Sure, the potential for improved scaling and efficiency is definitely there. I just don't see multi-GPU having a significant resurgence.

Plus, you can easily run two GTX 1070s or RX 480s off a 600W PSU. Probably even less.

Also, there is no lack of 800W+ (heck, even 1200W+) PSUs with good efficiency today. That market is well provided for already. It's time to provide better efficiency to the mass market.
