5 2879S HOW BIG POWER SUPPLY DO I NEED?

Depends on who built it and why? Reason I say this is normally the driver is a 2290. This means it was a custom build, probably class C. Running hard wide open you might see 70-90 amps draw, 50-60 taking it easy and talking normal.

class c,you are talking 100 or so...ab1 55 to 70...

My AB biased X-Force 2x4 base box has an 80 amp supply in it @ 12.1V, and it runs fine. 2-2290's and 4-2879's.

I'd think you'd be ok with 80 amps.

If it were me Ide get a 100 Amp reason being is it will leave plenty of head room or breathing room due to the extra Amps available people run there supplies hard and the more you run a supply taxing it out to its limits your obviously takink or robbing it of its lifespan.

I like how X-Force now calls the 1x4 all 2879's their med drive. If they want to come out with something new give us a nice regulated AB fan cooled line with switched SSB delay.

The rule of thumb is 20 amps per 2879.
