Experience: 2 Weeks
Great price
Somewhat quiet
None so far
I bought this for an HTPC build. So far it seems quiet enough that it does not interfere with sound. Quite happy with this purchase. Nothing bad to say about this product. Seems to be great value for the price when on sale.

I've had a number of these over the years and never had one die on me.
None yet!
Excellent for the price point. Never personally had one failed. Used in many machines. Solid power supply.

Experience: 7 Days

work really well
Not a bad power supply. It has enough cable for everything and the price is not too expensive.

Experience: 2 Years
Price and Bang for the Buck
none so far
Though the reviews are mixed on these CME PS's I can say after 2 1/2 years mine ran through the life cycle of my e84 Intel and currently resides in my sons build. If you don't overtax this PS SLI or Xfire you should have no problems. I have since upgraded to a Seasonic 750 in my new build but this unit is still chugging along. Just a foot note, it is still ery quiet.

Experience: 8 Months
Got this power supply for a good price to use for a work computer. It does its job, I have no complaints.

Experience: 6 Months
-Quiet, no squealing under high load
None really
Runs my undervolted A8-3850 with TWO 5750s in crossfire, 4x4gb memory, 2 hard drives and a large amount of USB devices.

Pretty good for $35 =)

Experience: 2 Months
Price for a 500W
None atm
Bought this for 2 builds, a business style desktop and a light gaming build. Solid so far, although the cables sometimes feel too "stiff" and aren't willing to be more flexible... end that thought in your head please. lol

Experience: 1 Days

Installation was easy only taking extra time to insure ATX power layout was the same as the HP power supply I was replacing. The PSU fan is slightly louder than the PSU fan of the original unit I was replacing, but seems to keep the case a degree or two cooler. Great Price. Fast Delivery
Slightly louder power supply.
Should have read the Tom's Hardware review of the power supply before ordering.
This power supply in the end fixed the problems with false system starts I was having at a reasonable price.

Experience: 30 Days

solid construction
price (on sale)
none found
bought this power supply to replace a dying Enermax unit in my backup box. Happy so far. Cabling is a bit stiff but nothing that a little massaging won't fix. Quiet operation verging on silence.

Experience: 1 Days

good price easy installion
none that i can see
over all good product would be best for bugeit builds
