Nitpicking, but Darkseid's beams didn't have no effect on Supes in the Casey issue. They were clearly wearing him down and he seemed to acknowledge the threat (and need to immediately break out of Darkseid's grip), although they had nowhere near their usual effect. Actually, the Omegas still overpowered HV just as DS physically won the contest of strength to get in that chokehold:

Regardless, something to note is that Darkseid had just delivered a HUGE blast to Imperiex:

Superman himself mentioned in MOS#117 that Darkseid was weakened by "the full expenditure of his Omega Effect." Now, while it doesn't say WHEN he expended him, IMO it's obvious he used up most of their power on Imperiex. The only other interpretation you could have is that he gave Imperiex (a being whom he acknowledged as a threat to his entire universe) a minor blast, then delivered huge blasts to Superman (a guy he'd punked in all previous encounters).
Since the OE had the same effect on Grayven as it had on Supes in the same issue:

... Whereas earlier in OWAW, a blast meant not to harm Supees, but just goad The JLA into battle had more effect:

... That seems consistent with OWAW's plot. Also, Superman even whole sundipped was unable to do that much damage to Warworld. OTOH, it was implied that Warworld would be outright destroyed, realeasing Imperiex, if Darkseid blasted it:

Also notable is that his personal power, once recharged by Amazon prayer, literally recharged the entire planet of Apokolips, which had been sucked dry of its energy.
