We were surprised with this power supply. With so many people saying bad things about the many previous incarnations of Solytech we were expecting a power supply with low efficiency and that couldn’t deliver its labeled power.

This unit could deliver its labeled 600 W at 47.3º C, which is wonderful, plus we could pull up to 675 W from it, and it survived!

But this isn’t a “perfect” power supply. Efficiency drops below 80% when pulling its full 600 W power and also noise level is far higher than we wanted to see.

OCZ StealthXStream 600 W is a better product because it provides a higher efficiency and lower noise level than Rosewill RD600N-2SB-SL-BK. However, if you want an honest 600 W power supply that costs less than this model from OCZ, Rosewill RD600N-2SB-SL-BK is certainly a very good option if you are on budget. Just be careful, Rosewill’s website says that this unit’s MRSP is of USD 126, which is insane. Newegg.com sells this unit at its correct USD 68 price tag.

Keep also in mind that there are several other power supplies that are internally identical to Rosewill RD600N-2SB-SL-BK (see a complete list on the first page) and they should get the same performance as the reviewed model.

Researching on the web we found out that MSI TurboStream 600 W is being sold by only USD 56 at Amazon.com, bringing an even better cost/benefit ratio than this model from Rosewill (even though internally these two units are identical, this model from MSI uses two 80-mm fans instead of one 120-mm fan though).

In summary, comments saying bad things about this power supply on forums around the web are pure speculation, based solely on Solytech’s past and not on actual testings. Of course there are better 600 W units around, if you have the money to buy them. If you don’t, this unit is a very good choice if you have only up to USD 70 to spend on a power supply.
