Got this power supply when it was extremely cheap. I like how the cables can be detached when not in use, allowing maximum air flow for my case. Overall, amazing price for a solid power supply.

Great price. Very reliable. Simply works with a lot of future upgrade paths.
This is an inexpensive high wattage PSU. Simply put, it is well worth its cost (which is low to begin with). Nowadays, an average system draws 500-600 watts from the wall at the peak. This will cover most individuals. Three card - four card setups will require a higher wattage psu.

Solid design. Quiet.

Everything you expect from a power supply, the quality of this power supply at this price is a really good deal.

Looks good
price was right
Haven't experienced this yet. I didn't get a single sata power connector with it. Looks like i have to many Ide power connectors though. Gonna have to try to take it back.

Got a new one, gotta love those ncix guys.
No Questions, looked at the old one, made sure the new one had the right stuff in it, and away i went. Installed pretty slick works good.

Quiet, Runs cool with dual gtx 570 and is sexy!
nothing yet (not made by seasonic?)
Dont hesitate to buy... I would rather have a seasonic, but this is a much better value. (got it on sale)

buy it!

Experience: 2 Weeks
Great packaging
Lots of cables
Does its job
Expensive if you don't get it on sale
Not fully modular
Originally had a 1000w OCZ on order, but after it got stuck in Abu Dhabi or Limbo or whatever for a month I switched it to this.

850w is still more than sufficient for my system, and while it's not fully modular I used pretty much all the cables you can't remove anyways.

I really liked the PCI-E power cables which come with little extra thingies that can turn them from 6-pin to 8-pin if you have a video card that needs it, such as my GTX 580. They're a little annoying to install but it still beats having to use an adapter.

But yeah after two weeks of use I haven't seen so much as a hiccup out of this PSU, so I'm happy.

Comment: We've seen the HCP series here before, and not too long ago, when the HCP-1200 was tested back in September. And that was an awesome unit indeed. The HCP-850 isn't too likely to be based on the same platform as that one was, so it'll be interesting to see what, if anything, is different.
