2 out of 5 eggsFan problems

Pros: solid lines, good power

Cons: 120mm fan bearings making noise, figures just after the 12month warranty, same as everybody else

Other Thoughts: coolmax doesnt even have the word warranty on their website....obviously not interested in return customers

2 out of 5 eggsalright, but died in a year.

Pros: looks good, 140mm fan, good quality looks. Works for about a year.

Cons: after a year and 3 months I expeirience random shut downs. a $xx FSP would be a better choice, I've had no problems with this PSU until I started having my system randomly shut off. (as a few other people states in their reviews)

Other Thoughts: I reviewed this PSU as e7 on 11/28/2004 10:59:20 PM. I've now had it for over a year and I do get random shut downs, my rig only consumes about 348w.

2 out of 5 eggsPretty on the outside

Comments: I got one of these power supplies about 15 months ago. It seemed to be great at first. It's very nice looking, was affordable, and has a 120mm fan.

After several months my system started randomly shuting itself down. Not very often mind you, but maybe once or twice a month. In the last month, it's gotten very very bad. At stock cpu speed and voltage the system would regularly shut down in the bios, starting the operating system, or while using the system. The only way to achieve some semblence of stability was to underclock the system to half it's normal speed and drop the core voltage.

At first I thought this might be a motherboard problem, but after doing a bit of forum research I found numerous people with coolmax power supplies complaining about the same problem. Finally a friend lent me his 400w powersupply to test, and my system has been stable at stock (and overclocked!) speeds since then.

While coolmax power supplies look nice, and seem to be fairly innovative with new features, I would strongly recommend looking elsewhere if you are remotely concerned about system stability.

5 out of 5 eggs

Comments: I bought one of these as a present for a friend and 2 months later bought one for myself. Both have been in service for over a year now. Now problems. VERY qiet even in my new antec sonata 2 case. I have the supply on auto and have not heard the fan kick up but verified it worked by feeding the fan with air from a hairdrier. Runs warm but gets the job done. Since I have purchased this I have replaced two other supplies in my kids machines with a total cost equal to what I spent on this. bottom line, you get what you pay for... recomended.

5 out of 5 eggsVery nice

Comments: I'm not sure if it's a new thing or not, but unlike the previous reviewer mine will support 24-pin connections through a supplied adapter. It also came with a 4-pin auxilary to 6-pin auxilary adapter. Now, for the actual meat of the review. This is one nice unit! The wires are all rather long, and there are a -lot- of connectors. The fan is relativly silent on the highest setting, quieter than the old PSU for sure. What really sold me on it is that the fan sucks in from the case, but the only way for the air to go is out the back. Some of the other supplies have vents inside the case that defeat the purpose of having a fan. The black color looks really spiffy, although it's high-gloss and shows fingerprints rather easily. All said, really nice! Powers my system (3Ghz P4, 2GB, 250GB HDD, 6800GT, DVD, DVDRW) without any problems.

4 out of 5 eggsgood ps

Comments: I've ordered 3 or 4 of these. I really liked them until I got one that was bad and it was a real hassle to figure out what was wrong and a big delay to replace it. (NewEgg was great - returned it and they gave me a refund).
Hopefully I just had some bad luck, but 1 out of 4 isn't great. The ones that worked worked well though.

They don't handle a 24 pin connection though (which some newer mobos are using). If you need a 24 pin connection, I'd recommend checking out the 535W Enermax. I've bought 2 or 3 of those and I love them all.

All in all, ps is good. If you order one and nothing is working or powering up though, check the ps before you trash the mobo.

5 out of 5 eggsGood Fan

Comments: Got this power supply for more RAM and new MSI 6600gt Pci-e graphics card. It cools my case very well at high setting, which is actually alot louder than the other two. Its got plenty of connections and seems to be working great with 2 optical drives and a 200gb hardrive. ill post back if she goes bad

4 out of 5 eggs

Comments: Good PS. I chose it because it had the 120mm fan with speed control, 500W, and didn't have all the flashy lights. The fan is quiet, even when set on high, so I just leave it there. Ample plugs to go around. I power my Athlon 64 3500+ in an A8V Deluxe MB, ATI 9800 All-In-Wonder Pro, WD 74GB Raptor system drive, WD 250GBX2 in RAID 0, and an 8X DVD Dual Layer Burner with it and all is well and holding specs like a rock.

5 out of 5 eggs

Comments: PSU is good so far. Doesn't run hot.You can hardly tell the diffrence on the 3 speed fan, but it's very quiet. All the wires are long enough too.

great price for the quality.

5 out of 5 eggsPowers my AMD 64 system with grace

Comments: I am running a MSI KT8Neo FIS2R board with an AMD Athlon 64 3000+, ATI 9800 Pro All in Wonder, 160GB SATA drive, DVD burner, and DVD/CD combo writer among other things in a Antec Sonata case; and runs these 24x7.
No problems at all. Is quiet and reliable. The price is right too!
I would recommend it.
