    deal alert: SP-320-5 PSU's for $40 + $9.99 shipping (active PFC, variable fan, etc)

    I'm not affiliated w/ the seller in any way. I just came across the deal and thought I'd share w/ the community. They're new and the seller has great feedback:

    55A @ 5V, auto-switching, active PFC, load-based fan speed (sooo much quieter than the S-600-5's I tried, even with the fans at max speed), etc.

    5V @ 55A.
    How many Teensys can that support?

    Well if you're ONLY powering teensies... um... a metric crap-ton If you're also powering WS2812b LEDs, then quite a few! I keep forgetting to order a fuse for my DMM to measure actual current draw on my strips; according to Ray Wu, the WS2812b strips need around 7.2 amps (36W @ 5V) per 5-meter (150LED) strip, but Paul's numbers indicate the current demands are a bit higher. Anyway, about 1000-1100 LED's per PSU.
