I am thinking about buying parallel miner PSUs for my L3+ to come.  How are the reliability of these PSUs?  Also, L3+ are rated at 800W + 10% each, and parallel miner 2400 W claims it can power up to 3 L3+.  Can I reliably do that? Theoretically required power draw from 3 L3+s can be 2400 + 240 = 2640 W.

Thanks.
