Delivery Contents, Power Rating and Fan

Rosewill comes with the usual assortment of extras. You get a standard power cable, four screws for installing the PSU, ten cable ties, a user manual and a seperate bag for all modular cables. The user manual has a few short instructions on how to install the device and shows some products details.

The maximum load for +3.3V and +5V is 22A each, which is enough for a modern PSU. Together, these outputs provide 130W. The Hive 550W has one +12V output, which can be loaded with 38A according to the manufacturer. As you can see the PSU is ErP-ready formerly known as EuP.

The fan is an RL4Z B1352512H from Globe Fan. This 135mm model is used in many power supplies that are manufactured by High Power. With a maximum of 1500RPM it has a moderate speed within the RLXX series, and it can reach a sound pressure level of approximately 29 dBA. However, since the fan output starts at 6V the noise levels are usually not that high. The fan uses 0.33A and consists of 11 fan blades with rough edges.

    bathotropic is trying to say:
    "I'm too ignorant to realize that someone whose first language is not English has a higher chance of making a slight spelling mistake.
    Even thought the word is spelled correctly when used the second time in the same sentence, I have no life and want to convince myself that I'm superior to others by pointing out inconsequential errors."

    Translation: bathotropic is trying to say:"I'm an a$$hat who acts like a third-grader because I'm on the Internet."

    Thanks for clarifying.

    This PSU is too expensive for what it's offering. Besides, ignoring the marketing, this is really a 450W PSU, not a 550W one.
    I'm curious what FSP has to offer in that market segment. They used to have really good low and middle-end offerings.

    Since Martin ran it up to 110% where it remained efficient and well in spec, and it did not choke, smoke, and croak, I'm not sure I understand why you are asserting that this is only a 450W PSU. Rosewill may have wrecked its PSU reputation a dozen years ago by selling junk, and the tech world has a long memory, but Rosewill seems to have cleaned up its act in recent years.
    The outright lie about the Japanese cap does concern me, but that could be a lie from Sirtec to Rosewill as easily as a lie from Rosewill to consumers; hopefully they can beat their supplier into submission on this one. Iirc, Sirtec was the OEM on some of OCZ's more questionable offerings, that started out well enough, but didn't hold up; this could be another like those.

    Quite simple really, 12V output is 456W, not 550. If you take a look at quality PSUs you'll see their 12V output is almost the same as the advertised wattage of the PSU. If I make you a PSU with 500W on the 3.3V line and 100W on the 12V line and mark it as 600W will you put it in any pc? Fact is, all modern power hoggers in a pc, the CPU and GPU both consume 12V and that's what mostly matters. If you make a PSU with 450W output on the 12V line then mark it as 450W, anything higher is misleading.

    Also, Martin has just reviewed 2 more PSU's from Rosewill, note how their 12V output matches the power rating this time.

    Can you please elaborate on how you arrived at the 456 figure? Was it by a P=I*V calculation? I could not find that figure anywhere in the article.

    Being NewEgg's house brand and generally low priced, I can't say I'd trust EVERY Rosewill product out there, but they do have some that are nice and worth consideration.

    Recently I put together a system with one of their Green series PSU's after reading the Hardware Secrets review....was going to go with the RG530-S12 but then there was a promo on the RG630-S12 putting it cheaper so I went with that instead (fairly easy decision to make...more juice for less $). Anyway it's been a solid PSU and I've heard no complaints from my customer. IMHO it certainly beats the Corsair CX line of which I've had no luck getting one that didn't have coil whine (and therefore I've quit using them).

    Finding a reliable lower wattage PSU around the $50 range that isn't junk is getting hard.

    Right at the start of the article: "In fact this is the frist time we test a PSU from this company"
    Frist -> First

    This psu sells for $44.99 with free shipping on newegg, all the time. At that price, its the best bang for your Buck.
