SilverStone to Release Nightjar 500W Silent PSU Later This Week
SilverStone is on course for releasing the Nightjar ST50NF this Thursday. The ST50NF is a 500W, fan-less (completely silent), 80 Plus Gold compliant, non-modular power supply (PSU). The PSU does away with the 120 mm fan, and replaces it with a large aluminum heatsink that draws heat from numerous smaller heatsinks below that in turn draw heat from the various hot components. To try and offset the weight it puts on with all those heatsinks, and to make the unit airy, the outer body is made of thin perforated aluminum sheets.
The Nightjar ST50NF delivers 500W of continuous power, it is standards-compliant with ATX 12 V2.3 & EPS 12V. It features active PFC (power factor correction), and uses a single +12V rail design. All its cables are fixed to the unit. There should be enough cabling for a performance PC with a single graphics card. The PSU carries an MTBF rating of 50,000 hours. SilverStone's Nightjar ST50NF will be priced at €129.

And the 80Plus report (for the 2011 version) shows Silver compliancy, not Gold (80Plus PDF currently unavailable so here's a Google cache).Looking at the results of the 80Plus report, that number could actually be ~75W (as it could be for any 80Plus Gold 500W PSU).
Comparable products to consider:
Kingwin Lazer Platinum Series LZP-550
Kingwin Stryker STR-500
The LZP-550 is based on Superflower's unfortunately named "Golden King" 550W, but I've seen neither the Superflower nor other comparables like the Huntkey X7 500W for sale anywhere.
And I think this is great for HTPC/home servers. I'd get one.
