Join the Discussion - To hell with nVidia's definition of SFF ready. What should be the actual SFF standard?
So i wanted to compact the connector design, so I designed a pcb for this. I currently have 10 wago connectors lmao. They're limited to 20 amps each. So its kinda sus. the PCB suppose to have a heatsink on teh bottom for cooling. I might add a pinout for the PICO connector at the top of the PCB
Now i run into the question: since the manufacturer for LOP600-12 uses m3.5 screw terminals, can I do the same? According to digikey those terminals are rated for 15A.
Are the via holes on teh bottom giving it the extra current capacity?
or I should I use recubes? they cost $4 on digikey, but they can handle 130A or I can get the 100A version for $2. any thoughts?

I would just use through-hole with large soldering pad sized for the wire you're going to use. It would have a much better contact. I would also solder a second set of wires on the backside of the MW 600W as pictured. So two sets of 12 AWG if you're using the full 600W rated.
The rating of the terminals also depend on the quality of the finish. I would prefer to see 2 set of screw terminals... seems to be an oversight by Meanwell. A 50A connector should be on M5 or M6 screw sizes.
Thanks for the suggestion. I will make a version of the board to try to solder wires directly.
per your 2nd suggestion, I don tthink thats possible, as the pads on the bottom side is only connected to the positive trace. Its kinda hard to see, but theres a ring around the terminals of the negative trace
Kinda sketchy but maybe use the solder legs on the screw terminal?
What's the nominal power for your project?

Very sketchy tbh.
I have a undervolted 5700x and a 6750xt undervolted to 1160mV. The theoretical wattage should be around 300w, but i never tested the actual power draw. The temps never goes above 75c in my current setup
Hi, I found this PSUs as well but i can't understand the stand-by function. On the datasheet i can see how much power they're consuming while in stand-by but it's not clear (to me) when they go in stand-by.just FYI ... I recently came across MORNSUN power supplies which seem a lot like "MEANWELL inspired"
specs and build quality looks fine, so maybe that's an alternative for some of you...

For the LOF225 "standby power consumption" means: if no load connected. It does not have a PSON function if you were looking for this.
