Hi - I'm trying to choose between these two PSUs. Both are 650W but have different ratios of their 3.5 / 5v and 12v sides.

SeaSonic G-650W 80Plus Gold Modular
maximum load
20A +3.5V
20A +5V
54A +12V
combined: 100W and 648W
total: 650W

SeaSonic M12II 650W 80+Modular (Bronze according to Seasonic site)
max
25A +3.5V
25A +5V
53A +12v
combined: 150W and 636W
total: 650W

My question is what kind of things would you be using more of to make you choose the second model with the higher 3.5 / 5v?

I know the the M12 II is on Tom's Tier 1 and the G model is in Tier 2A.

And that list at realhardtechx says the M12 II is discontinued, does that have any bearing on things?
Johnnylucky's list doesn't have the M12 II - probably because is is discontinued I guess.

They seem to me to be the best Seasonic under $150 at my local supplier:

Any suggestions would be much appreciated.

You want a higher 12v now a days, 3.3 and 5v aren't used much by the system, most everything runs off 12v, and the devices powered by 3.3 and 5v wont draw much power.
It may be discontinued because they introduced a new model.

If i were choosing this for my own computer I would get the G-650w.

Devices for 5v and 3.3v would be SSD's (they can also take 12v), USB devices (5v), a floppy drive (5v)
