I've read somewhere (Deathwatch rulebook?) that power armor is over 400 lbs, and Terminator armor is close to a half-ton.

Considering that Astartes are supposed to be over 7ft tall, and weigh about 600+ lbs, it makes sense. Modern tactical body armor is roughly 35-40 lbs, average height & weight of a soldier about 5'9" 180lbs (US Army standards). Although Power Armor would be much larger, and weigh much more than body armor, it wouldn't be proportionately heavier, as it's made of lighter materials than steel (futuristic ceramic composites, etc.)

So, fully Power Armored Space Marine would be about a half-ton, and in Terminator Armor would be roughly 1,500 lbs.
