First lets start with the items themselves:

As you can see, both very similar items, with the Power Core coming out in the lead with MUCH better resists. For those that don't know however, the Power Core comes from a raid mob in the Rust, an area for exp groups with a few raid targets, while Fedraz comes from Farguziar in Inner Prison, a zone that requires keys and progression through other zones/other parts of the zone. Farguziar also requires pulling at the very least 3 mobs, two of which are basically copies of Master of the Everchill, then you need a raid force with at least one knight class and one enchanter (if you're skilled and overgeared for it, I would recommend a Paladin and at least 2 enchanters).
Basically, Fedraz takes way more effort to get (hell getting into Inner Prison itself takes more effort imo) than getting the Power Core. I feel the stats -mana and resists most of all- need toned down dramatically, as the Power Core is overpowered if you factor in Risk vs. Reward and effort/time spent.
edit: have to click on the links i guess, for some reason the pictures won't show up for me
