Im in the closing stages of planning my LED installation which will require about 1,000 SK6812 LEDs. If you believe the datasheet, they are 90W per 5m and at 60/m Im looking at about 16m which is about 288W at 5V.
To me this is a big number (may not be to others!) and want to proceed with caution a bit. Ive got a QuinLED Digi Quad and plan to use 4 channels of about 4m each. Ive seen plenty of ~300W 5V power supplies but have also read that using 2 x 150W is possible (obviously not connecting the lives together!)
Just wondered what people prefer - 2 smaller or one big supply?
All depends on you layout and what is more convenient, technically there is no real difference.
Dont forget to power-inject about every 5A worth of LEDs.
Thanks. I figured there is little difference, I guess my main concern was the numbers. Im a relative newbie and 300W feels like a lot, 2x150W seems a bit less startling!
Its going to be in my garage/outhouse so concerned about safety with the big numbers.
bth i like bigger units, if i need bit more power meters out i just inject more down the line usually not the case tho. depends too how your are using them, white, solid, high/max brightness, mostly effects etc… chart i found is for max brightness more so in white.
Note: its suggested to use a fuse, some bigger more expensive boards have them.
