3 out of 5 eggsSome good features, but short cables &

Pros: I've been using this power supply as a replacement for the unit in my Dell Inspiron 531s since May 2011. Still works and still runs quietly. The connectors are better than the OEM unit; this has a 20+4 main connector and both SATA & Molex connectors. The Molex connectors made it easier for me to use an IDE hard drive with IDE-SATA adaptor in this system.

Cons: The CPU power cable was too short, so I had to spend another $5 on an extension cable. The system is unstable at max load and does experience abrupt shutdowns. Currently my system is maxed out with 4GB RAM, a GeForce 210 video card and an HDTV wonder tuner. The shutdowns seem to occur when the memory is maxed out or when I'm trying to watch TV. Definitely seems like this unit would need to put out more than 300W to meet my needs.

3 out of 5 eggsOkay power supply, wish it put out a little more power...

Pros: I've been using this power supply as a replacement and marginal upgrade for the OEM power supply in a Dell inspiron 531S. The system is maxed out on RAM with a single hard drive. The power supply has been pretty reliable in frequent use since May 2011. It runs quietly too. The connector is a 20+4 pin arrangement (better than the 24 pins on the stock PSU) and there are molex connectors present which came in handy when I was using an IDE hard drive with an IDE-SATA adapter inside my case.

Cons: The CPU fan power connector is shorter than on the stock PSU, so I had to get an extender cable for around $5 to hook it up to my motherboard. I've also had issues with the machine shutting down on occasion. This usually seems to happen when I try to watch TV on my HDTV tuner.

4 out of 5 eggsquiet and stable so far

Pros: A little too small for the back of my Mini case, but I decided to use them. Quiet and provides stable power for a quad core system used mainly for school work (I teach high school) burning CDs, surfing the internet and these types of activities

Cons: none

Other Thoughts: make sure u measure the opening on the back of your case for the power supply. will someday replace my current case with the mini rosewill that uses this power supply; so I will use this power source as a backup.

1 out of 5 eggstwo for two

Pros: NONE!

Cons: Purchased two of these units earlier this year (January), and the second one just died on me! Originally posted a positive review, but who knew they would both die on me in less than 11 months. Don't think I'll return because of reliability of the replacement unit I'll get. Never did send back the first one that died. Built three computers with this psu. Wondering how long the third supply unit will last? Would not recommend this unit. Not happy at all.

1 out of 5 eggs

Pros: Price

Cons: Bought two of these back in January of this year and one has since died on me. Not sure if it's worth sending back for replacement because of added shipping cost. Think I'll take a hit and cut my loss and try to buy one @ a local MC store!

Pros: None

Cons: The power cable for the mother board is not long enough to reach the mother board in my Micro ATX case. What a disappointment!

5 out of 5 eggsDecent replacements for OEM

Pros: Purchased two of these on two different occasions back January of this year. Both are workng fine. Bought them to replace aging/failing units in cases (purchased from the EGG) that were/are 4 + years old.

Cons: none to speak of!

Other Thoughts: These style of units are rather hard to find, so consumers are limited as to what wattage to choose from.

1 out of 5 eggsDO NOT BUY

Pros: None I can think of.

Cons: Does not power up.

Other Thoughts: Wish I could give this 0 stars. Bought the matching case that had the same model power supply about a year ago. Unit never did boot. Bought this power supply as a replacement, won't even power on. I connected a spare power supply, one that does not fit in this case, and the computer boots fine. I guess shame on me for not trying that sooner. RMA'ing this unit this week. 3rd product in a row from Rosewill in the past 30 days that was defective. Won't be buying any more of their products.

Manufacturer Response:
