4 out of 5 eggsPower Supply

Pros: Good power supply.
It didn't help the Hp Amd pc I ordered it for it seems the mother board is dead. Hopeing the power supply was bad I put it in another pc I thought would never go again and well it's going GOOD for now. Don't trust the green light or l.e.d. Also the Hp Amd pc power supply is dead.

Cons: The included power cord is a little short.

1 out of 5 eggsTerrible product

Pros: It does power on my device...

Cons: So when I opened the box, the tab which locks the main power connector to the motherboard was broken and floating around in the box. Second, the thing is VERY LOUD. Third, it just looks poorly constructed. I do not trust it.

1 out of 5 eggsDied after 3 weeks use

Pros: Cheap.

Cons: Died after 3 weeks use pulling constant 285W verified with KilloWatt meter. Cost more to ship it back than it's worth, so chop off the wires/connectors for spares, pull fan for whatever and junk the rest. I know it was loaded hard... but it's rated 300W...

Other Thoughts: This was the first (and Last!) cheapo PSU I will ever buy. Probably work fine for a Celeron or P4-478 or Sempron... something that pulls no more than 200W totat...

4 out of 5 eggsNot Bad

Pros: Works like a charm, has easily removable Molex plugs, and the 20+4 pin power connector has a cover around the cables.

Cons: Pretty loud. I could probably hear it if it were in another room on the same floor.

Other Thoughts: Great buy for how cheap it is.

1 out of 5 eggsDO NOT BUY COOLMAX

Pros: Cheap price

Cons: Died less than 90 days after install

Other Thoughts: Contacted COOLMAX. They provided RMA. I had to pay for shipping to them, and would be required to pay for shipping and handling if they decided to replace it. Read for yourself:

We will not be responsible for lost shipment; refused shipments; no receiver; and with wrong address provided. User is responsible to contact freight forwarder/carrier regarding this matter. User will be charged shipping and handling fee if RMA replacements are to be resent.

This RMA # IS VALID FOR 15 DAYS ONLY.

4 out of 5 eggsMy Mistake

Pros: Attempted to order the CM-300 but wasn't paying enough attention to the model... so I end up having to find a case to fit a Full size ATX PS rather than re-using my m-Atx case.... sigh...

Cons: Having to mount it outside of the old case until I can lay hands on a new one

Other Thoughts: ... must... read... more ... carefully.
