I thought looking these up on the UL database might help, but the UL listings don't seem to quite match the labels for these PSUs (making things even more confusing!), and sadly it doesn't list combined max wattages.
The middle three columns are Max Outputs for: V, A, VA
InWin UL Listing
FSP UL Listing
Now I would have thought that the bottom FSP table was for this unit as it's not 80 Plus rated which is presumably what the "(80)" bit means on the top table names, but the bottom table shows two ~20A rails (with 18A usable) which is a massive difference to the stated label amperage!
So based on the PSU labels, the In Win seems the obvious choice, but given the much higher UL rating, I'd be inclined to think the FSP is actually more capable...
