Most of our US and Canada based readers are likely familiar with Rosewill. The company started as a subsidiary of Newegg and they were initially focused on producing simple bits and hardware at competitive prices. As the company grew larger and diversified into other segments of the market, they eventually fledged into a stand-alone manufacturer, with myriads of products filling their ranks and exports outside of the North American markets. Our latest review of their products was that of the Photon 1050W PSU a few months ago. Today we are having a look at another one of their PSUs, the Hive 850W.

Unlike the Photon, the Hive is a series primarily focused on combining high power output and aggressive pricing. They are not lacking any tangible features, as they are semi-modular models with a black chassis. However, they appear to be a little behind technologically for new high performance models, they are just 80Plus Bronze certified and rated for continuous output at 40°C. Their retail prices are enticing but not excessively low, with the 850W unit retailing for $100 including shipping. As a result the question we're looking to answer today is whether the performance of the new Hive units can justify their price tag.

Power specifications ( Rated @ 40 °C )
AC INPUT 100 - 240 VAC, 50 - 60 Hz
RAIL +3.3V +5V +12V +5Vsb -12V
MAX OUTPUT 22A 22A 70.5A 3A 0.5A
140W 846W 15W 6W


Packaging and Bundle

The Hive is supplied in a sturdy cardboard box, with the artwork hinting that the origin of its name comes from the honeycomb finger guard pattern. Some basic specifications about the PSU can be found on the sides and the rear of the box.

Few extra items are bundled with the Hive. Rosewill only supplied the AC power cable, a few cable ties and the mounting screws. However, the modular cables come supplied into a nice reusable pouch with a zipper. The cables are "flat", ribbon-like, with black wires. Red connectors are installed on the PCI Express cables.

    Great review. I really appreciate that you test these less capable units. Reading this helps me to realise why those 1200 watt PSUs are so good. To see what happens when the cooling isn't sufficient.

    Also that this psu seems like it would be good for systems that might generally sit at around 2-400watts and occasionally pulls 5-600+ on a more epic game.

    Nice review. The PSU looks pretty decent up to around 500 watts and, realistically, that's about the maximum draw of most gaming computers even those running two GPUs (presuming about 100 watts for the CPU and then another 125-ish for each video card, plus some extra wattage for drives and other bits) so it's more than enough. As I've never found a reason to run more than one mid-range graphics card, I personally can't see buying anything rated over 450 watts. The price is a little too high, but aside from that, its good enough.

    "I personally can't see buying anything rated over 450 watts."

    In that case you can get a platinum PSU on sale (rebate) for less than the price of this one.

    Anything lower than 'gold' is junk. This thing is a budget brand 'bronze', blech, no thanks. That's why it's only a 3 year warranty, low quality components. It doesn't even look that great, enthusiast like snazzy, especially modders with window cases. Punching sheet metal with a honeycomb pattern has been around for years already, *yawn*.
