Unfortunately, you'd be surprised how many eBay sellers swap parts.
My SC836 (uses same PSUs) never had a problem swapping from the 920 watt gold, to the 920 watt platinum, to the 920 watt platinum sq.
There's def. something weird. I have that looking PSU in the microcloud.
While it goes into my 846 almost entirely it doesn't go far enough to "click" it is like 1/8" from going all the way in -- is that how yours is acting before you made it fit?
My other SQ and Platinums I'll have to check in a bit.

No, before I cut off pieces of PCB - it wouldn't even go in, I had to take about 1/4 of each side. Now it doesn't click in, but I will double check why and make small tweaks if needed.
Bottom line - connector was much wider on my platinum PSU and it wouldn't go in into PDU I have. If I had newer PDU - all PSU's would work, with smaller connectors too.

I bought some PWS-1K28P-SQ from eBay here: SuperMicro PWS-1K28P-SQ 1U 1280W Redundant Single Output Power Supply Qty Avail
My SC846 will take the PSU with just hacking the PCB on the small side (2 PCB tabs basically one is shorter than the other) so I didn't have to cut both sides. If it fits I should be good to go correct or do I have to also modify the other side as well?
I have 3 SC826s and all of them have distribution boards that would require me to modify both sides of the PCBs. My question is if I do that will they work in those SC826 since this thread is pretty specific for SC846? In looking at the PSU matrix from SM it lists the PDU I have available for a 2U chassis.

I dont know. Maybe you dont. And maybe I didn't have to either. I did it copying sizes I had on PSU I had originally
ah, ok that sounds logical. I'm just afraid of throwing it in there and blowing up equipment. What would be a good test to know whether or not they work properly? If the chassis turns on is that enough of a test or would I have to do form of measuring?
Cut up my PWS-1K28-SQ today to fit into my old SC846. Fan speed of 1088 RPM on server idle, vs ~6000 on my PWS-920P-1R.
Now to do something about my Dell switch.

After looking at Supermicro's web site for motherboard specs, I was wondering just how significant the chassis revision (M vs N) is to motherboard fitment or if it is just some quasi marketing scare tactic to steer you away for older chassis with newer motherboards?
Hmm... I would like to change the PSU from PWS-902-1R to either PWS-920P-1R or PWS-1K21P-1R for less noise primarily. Cutting is not an option. Not sure which PDU I have, will come back with more info. But I guess its the oldest one, 8824.
Which of PWS-920P-1R and PWS-1K21P-1R should I get?

Get the SQ model. If you can't find any, get the platinum's.
I just bought a couple of 920w platinums a couple of days ago for $59 each. Just checked prices and they are crazy stupid high on the platinum models. Just gotta keep an eye out, like everything else, deals do pop up.

Hey guys, I just read through this post and I would like to add some clarity for people with a 836 chassis (like me using a Dell Compellent CT40 chassis). The PDB part numbers listed above are not the story for the 836. The part number "PDB-PT825-8824" is compatible with the shorter PSU PCBs like on the PWS-1K21P-1R, but there is another part, "PDB-PT826-8824" which is "PDB with longer 24pin" according to Supermicro. So, just because you have a "8824" in your chassis doesn't mean you will or will not be able to use a Platinum SQ PSU, at least for a 836 chassis. I picked up a PDB-PT826-8824 for $20 shipped on ebay, which I think is fair to enable the use of the quieter PSUs. Hopefully this will save someone time in the future.
my suggestion:
why do you need to replace PDB that support >1000W PSU ? *save $ for something else*
this thread is discussing to use PSU >1000W that has wider slot due in need more power/ampere distribution.
since many do not use > 1000W. hacking the slot is easy without spending extra money.
or..
pick 500W, 700W, 920W platinum, 920SQ not much different with 920 platinum in noise level
.rule of thumb, use 30%-40% max to let the fan does not speed up..
I replaced with the goal of using the 920 Platinum SQ as you suggest, but ended up getting the 1k28 SQ for $65 shipped. I am seeking the least noise possible, as this will be in the office / guest room. I also need this to be silent when powered off, and my understanding is only the SQ series turn the fan off when the system is off but power is still applied (I read this about the 920SQ but could not verify for the 1k28SQ, hopefully they are the same in that way). I plan to power this system off when I need to my office very quiet and I do not want to have to unplug it every time. Eventual load will be 2xL5640, 12 DIMMs, 16 drives, 2x H310, and a dual port 10gbe card. I know the 920SQ would support that, but the 1k28 SQ keeps overall load closer to that 40% you mention, plus the PSU was half what a 920SQ costs.my suggestion:
