Rosewill has definitely delivered a nice balance between quality and price. The RP650-2 power supply will service a standard enthusiast system without issue. If you have a couple of entry level enthusiast graphics cards with a single power connector like the 9800GT or a single high-end card with two connectors like the GTX 285, the two dedicated rails for the PCI-E connections will ensure you have adequate power of up to about 36 amps. Just make sure you keep your case cool and the power supply well within the true maximum load of 630 Watts. The promised 650 Watt rating, as we discovered, was simply not deliverable.
So, how do we rate a PSU that does not deliver its promised ratings? - We certainly have to frown upon it for not running at reported maximum loads and falling out of ATX spec during Test 5. Sure, the general features are better than average with good cable lengths, nice sleeving, convertible cabling, a PCI-E 8-pin run and a nice polished finish, but you buy a power supply to supply power and, in this regard, it comes up short (literally). If this unit had a stronger 3.3V result and did not push the wattage claim over available power, it may have fared a whole lot better.
I would, however, cautiously recommend this power supply if you can pick it up for a good bit less than the RRP of $129 USD. At this price, I would look at something else. Is it a bad power supply? - No, but it is difficult to get excited about below average performance and an overrated output capacity. I guess you do get what you pay for and in spite of initial positive impressions, the Rosewill was apparently too good to be true.
