OCZ can be good or terrible, depending on how much you spend on their PSUs.
We hate Rosewill because Rosewill has only made ONE decent PSU, the rest are basically rigged to explode. This is why you don't go cheap on a PSU:

Ok.. I'm bringing this old thread up again because of a glaring misrepresentation of Rosewill power supplies.
First off... the power supply in that video is not a Rosewill. It has been confirmed long ago that it is a Raidmax RX-450K 450W power supply.
Here is a link to the power supply, still being sold on Newegg.
http://www.newegg.com/Product/Product.aspx?Item=N82E16817152032
That power supply is made by Sun Pro Electronics Company LTD. Which does not , by the way, make any power supplies for Rosewill.
Rosewill is Newegg's house brand and, as of right now, they four main manufacturers for their power supplies.
ATNG
ABS
Solytech
Deer
The ATNG units, which are the Extreme Series (EX-) and Performance Series (RP-), have been found by several trusted tech site to be very good actually. I agree that there are better power supplies to be had, but when tested these units received anywhere from 8 to 9 out of 10 on final scoring. Yes, efficiency, voltage regulation and ripple are not nearly as good as high-end power supplies found on the market (Antec, Corsiar, Silverstone, Seasonic....), but the regulation and ripple were found to be well within specs. The efficiency, while rated 80-plus, just missed the mark on one or two cross-load tests, coming in at 79 %... but otherwise it stayed at 80 - 81%.
The ABS units, which are the Libetas Series (LIB-) and Green Series (RG-), are good quality units that, like above, stay within specs on regulation, ripple, efficiency and rated power output. Although there are no reviews specifically tested under the Rosewill badge, some of the same ABS branded power supplies were tested and found to be pretty solid.
The Solytech units, which are the Stallion Series (RD-), did not fair as well under testing and found that , while coming close, could not put out their rated power output. This is due to Solytech listing their specs as rated at running under 25C temperatures.. which is a fairytale inside a PC. The regulation and ripple were also on the fine line of being out of spec, and on some units going out of spec by a bit.
The Deer units, which are the Value Series (RV-), are the worst of the bunch. Effeciency, regulation and ripple are a joke and this is where Rosewill takes a dramatic turn for the worse. This is the major "black eye" for Rosewill branded power supplies and I think that Rosewill/Newegg should just drop this line, and possibly the Stallion line, altogether.
I hope that shed a bit more light on Rosewill power supplies.. instead of the usual forum reply of " Rosewill PSU's suck... stay away...."
