5 out of 5 eggsRosewill R379-M case PSU replacement

Pros: My customer managed to kill the PSU in their 'puter (that I custom built them in 2011)- by dropping the entire computer case onto a concrete floor.

The Rosewill R379-M case wasn't damaged, but the PSU took the brunt of the hit. The PSU didn't make it... :(

I was worried about matching this small footprint- but this was the identical replacement.

Cons: Won't survive a 6' drop onto a concrete floor...

Other Thoughts: All cables seem to be the perfect length for my slimline MicroATX case.

This PSU is running a Core2 Dual Core E8400 mounted on an nVidia E7AUM-DS2H with GeForce9400 graphics. That board requires a lotta power.

..in addition to a WD Caviar Black HDD, a Mushkin SSD, a DVD and a 3.5 floppydisc.

Runs perfectly for me.
Never had a problem.

Pros: small size

Cons: lasted 90 seconds and died. I was replacing a 250w PS with this one, it should have been fine.

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!

1 out of 5 eggsToo short!

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.
