5 out of 5 eggsIt outlived its usefulness?

Pros: I honestly can't remember why I bought this. My order history shows Norco stuff so I assume it was for that. The same model PSU was in the rack more than a year before I got this one. The straight through airflow design was very hard to find for under $40 so I probably snagged this to minimize downtime between failures.

Cons: Rather than blow up like every other PSU, the failure stops here. Both units have run 3-4 years and the recent one outlived its usefulness. So, bad job Cooler Master, you made something indestructible? Now do it again! :)

Other Thoughts: I would really like to see Cooler Master make straight modular power supplies. Weird flow designs like the Norco racks need to be uncluttered really bad. Now that I have a tried and true PSU with no purpose I'll probably use it when building a system for a friend.

5 out of 5 eggsGood PSU

Pros: Good Power Supply Unit
Doesn't Make Any Sounds
Last's for 2 Years at the Max

Cons: Have to Replace The Unit Every 2 Years After Long Uses

Other Thoughts: It was a good power supply while it lasted. Newegg doesn't supply it anymore but that's okay due to how old these things are.

5 out of 5 eggs2U certified!

Pros: If you're using a Norco 2U, you need an ATX that 'blows through' - not too easy too find; most PSU's these days 'suck from' the top, with a large fan - won't work in a server chassis, as the lid is +- 1/4" from the PSU top... This un'l do the trick!

Cons: None yet - way more power than needed for an eight drive 4GHz Clarkdale driven server...

5 out of 5 eggsGreat for older rigs.

Pros: I put this in my girlfriends computer because her PSU died. It works like it's supposed to. Haven't had an issue with it at all.

Cons: It's not pretty.

Other Thoughts: Good for older rigs and lower-end machines.

4 out of 5 eggsstill works

Pros: worked great but

Cons: i had to add a few inches to some of the cables going to the hard drive and cd drive
this item was for the the smallest case out thier and was still to short by 2-3 ins
had to leave the hard drive dangling loose

Other Thoughts: removed it and put and comp for dad. he'll never know. got a new 400w one for myself. now i might have to much cable but that is better then not enough.

4 out of 5 eggsCheap, Reliable, Low Wattage

Pros: Cheap and reliable. I've used this in a home server for a couple of years. Rear facing fan is great for cramped, heat challenged cases and it was nearly inaudible. Decent supply of basic connections.

Cons: No 8-pin connector. Probably due to its age, however using an adapter works just fine on my Gigabyte AMD785. No PCI-E power connectors, but then again this isn't much of a gaming PSU so I wouldn't count it against it.

Other Thoughts: I deducted 1 egg because I feel this isn't the best PSU you can buy for the money or in its price range. Its starting to show its age, however if you need a reliable PSU for a low wattage system then I'd highly recommend this over similarly priced (High wattage / lower quality) units.

5 out of 5 eggsVery nice

Pros: So far so good. Runs very quiet, cannot hear the fan even in the slightest.

Cons: As another user mentioned, only 1 SATA branch with 3 connectors.

Other Thoughts: I placed my optical drive in the lowest bay, and the first hdd in the highest bay, and the cable fits just fine.
If you have a whole mess of drives, this may not be the best p/s for you.
