5 out of 5 eggsrosewill rules!

Pros: long wires.more than enough molex connectors.20+4 pin connector,2 sata connectors,4 and an 8 pin atx connectors for intel motherboards.QUITE!

Cons: 400s has no pci express connector.the 500s and 450s power supplies that i have gotten do have pci express connector.

Other Thoughts: i have used rosewill power supplies in all my pc builds in last 3 years and never had a problem.the only other power supplies i use are fortron and antec.and these rosewills rank up there with antec in quality.the only thing to keep in mind is look at rail amperes this has 18 on 12 volt compare to antec and is like truely a 380 watt p/s.but it will run pretty much any single video card system out there.

5 out of 5 eggs

Pros: Very quiet, second only to Seasonic. 120mm fan. Cheap.

Cons: None.

Other Thoughts: I've put about a 15 of these into systems in the last 12 months with no issues. Systems have been 3200-3800+ Athlon and Pentium D 930 business rigs with the usual compliment of accessories.

5 out of 5 eggsGreat PSU for the price

Pros: I've installed many of these (and similar 400w rosewill model) power supplies for my customers over the last couple years, probably at least 20. So far none have failed or come back. Any other psu I've tried with these specs in this price range has been total garbage.

Cons: None

Other Thoughts: I run a repair shop and suffered with a lot of cheap power supplies that were DOA, or didn't last long.
Now I buy the Rosewills every time, these for high end systems, and enthusiast customers who want quality, and the cheaper 300W models for low end systems and people on tight budgets.

2 out of 5 eggsgood for exactly one year

Pros: This PS worked perfectly, was quiet, affordable, plenty of power, and stayed cool.

Cons: One year and one week after installation, the PS died for no reason and without warning. Computer just shut off during idle and didn't respond to switch. Tested the PS, and sure enough it was dead. Warranty was one year, so it expired about a week ago.

Other Thoughts: maybe I'm just unlucky, but if you use this, make sure you keep good backups, and have a plan B around the 365th day of operation.

5 out of 5 eggsgood PSU

Pros: quiet

Cons: the fan on the bottom is partially covered by the case i put it in, so maybe that is a con for the case instead of the PSU.

Other Thoughts: nice voltage rails from this, slightly above 12, 5, 3.3. i would buy again when i need a 20+4 atx PSU

5 out of 5 eggsGood Power Supply

Pros: The Power supply is quiet, supplies power, and was easy to install. It has plenty of power connectors for all my stuff, but mostly its quiet. Quiet is a big deal, and this meets that requirement

Cons: none that i'm aware of at this time
