Hopefully someone reputable gets this thing in for review - I want to see how well that powercache feature actually works.

Shame they still use that terrible sleeving method. Those massive black plastic things make cable management so much more difficult. Why oh why couldn't they just use normal heatshrink?

As for the PowerCache...
Quote:
PowerCache™ is a technology that helps to stabilize the power output to CPU & video card. By adding a 2200µf capacitor at the end of the CPU and graphics cables, power can be delivered instantaneously where and when needed rather than from the power supply itself. For example, a 23A increase of demand from the CPU or GPU could cause a voltage drop of 1V causing a crash or reboot. With PowerCache™, the voltage drop will be just 0.2V, keeping the system running and stable.
Interesting concept, but it adds quite a bit of bulk to the CPU and PCIE cables.

That's actually what I'd really like to see - a 2200uF (the unit they showcased awhile back said 3200uF?) capacitor small enough to actually fit inline like that.

Somewhat on the front of the box:

The cap idea's a really great idea. any one see the jonnyguru where he put a cap on the beginning of the modular cable(i think it was the pci-e) on a BFG psu and it reduced the ripple?

Hmm, I understand at least one known reviewers are getting this unit, but the graphs in this review don't look all that promising, actually.

But at least I can see how they pulled off the 2200uF inline cap thing - the caps are only rated for 16V.

They're probably just further overstretching the guts of an 850- although full load on one of these things isn't a condition you're going to run under very much.

+3.3V voltage regulation wasn't great, but aside from that the PSU's performance was very good.

Not by a long shot. This unit uses a completely different platform from the older Truepower Quattro units.

But some of the 12V rails drop over 0.3V, and the voltage ripple was nothing to write home about either, on any of the rails. Certainly doesn't seem like those extra caps are doing any miracles.

It's not that it's a failure by any means, maybe I'm just a little jaded by some of the other 1kW+ offerings that have hit the market recently. If I actually needed that kind of power, I'd like to know that the maker/designer used the technology available to provide the power properly. Silverstone's ST1500 that JG just reviewed only had a 0.09 drop under full load, despite handling 300W more. I suppose it's selling price will determine how good of a value this unit is.
