COOLMAX NW-650B 650W ATX12V v2.2 SLI Ready / CrossFire Ready and Compatible with Core i3/i5/i7 Power Supply

Pros: Works great Powered my powerhouse Core i7 1366 Socket 950 rig fine. Until I started playing a game and using my computer heavily.

Cons: Horrible on high load. PSU got very hot to touch in the back and started sputtering whine noises. Felt like I was reaching my power limit but I thought this was a 650 Watt PSU should of been enough. Was wrong, maybe it isn't. For a low- mid grade system this would of been fine. Forget high performance out of this PSU.

Other Thoughts: Bought a Cooler Master Silent Pro M2 RS720 instead. Hopefully it'll handle the powerhouse of Overclocked Core i7 CPUs.

Pros: It has really nice cabling and connectors along with a good price.

Cons: I was sitting at my desk and heard a loud "bang" combined with my computer turning off and smoke. I think a capacitor blew.

Other Thoughts: I was really happy with this supply when I installed it. I was less happy when it died a week later.

Pros: Product is exactly what I needed and easy to install. Fan is silent.

Cons: none so far, it just works

Other Thoughts: Bought this to power my GeForce GTX 560 Ti.

Pros: Decent price. Details and overview painted a pretty picture

Cons: You get what you pay for. I expected it however to atleast run ONE gpu without any hitches seeing as in the description its rated for Xfire and SLI. So who likes being lied too? I dont. Its straining under a very low load and Im pretty upset about choosing to spend less. Wont happen again especially on a "Coolmax". I dont see how lying about a product is ok.

Pros: Simply awesome. A good gaming system will only pull ~500 watts from the wall. Mine has been pulling 500 consistently for 5 years! Also, newegg is such a great site, fast shipping and great reliability.

Cons: NONE

Pros: Got two years out of this unit... ran 3 hard drives 1 optical 125watt cpu and twin nvidia 9600 GSO's (not in SLI) on a gigabyte MB. but those graphics cards have low power requirements... Yesterday I dropped them both for a single 6790 radeon and ...

Cons: Today it died.. almost exactly two years after purchase. It went out in a blaze of glory... the sparks lit my entire room for about 4 seconds. blew past the surge protector my PC was plugged into and tripped the circuit breaker in the garage shutting down power to about a quarter of my home. Reading up on coolmax PSU's it would seam a lot of people are having issues with many of their PSU models. Coolmax seems to replace faulty items quickly and their is a long lasting warranty... but so many shouldn't need to use that warranty if they didn't make cheap stuff.

Other Thoughts: I recently added in my first high end graphics card. This marked the death of this PSU... but if it is crossfire certified and I only added in one graphics card why did this PS literally explode on me? I was having problems before the card... got up to 5 hard drives a month ago and was having issues turning on the PC... unplugged two of them and it seamed to go away. In the middle of a GPU stress test snap crackle and pop this thing lit up!
Hard drives use about 30 watts when they are spinning and at no point are all of them spinning at once... most of the time all but the C: are asleep. regardless when this PSU blew up the extra hard drives were not even plugged in... it was the Graphics card alone... a single 6790 crippled this PSU.

If any of my components are damaged... Newegg is not the only place I will be warning others of how cheaply built coolmax PSU's are.

Pros: none

Cons: I used 2 of these in builds for clients. BOTH of them have fried motherboards and other hardware as well. I will never buy a CoolMax power supply again.

Other Thoughts: Don't waste your money on this. just go look at something decent like Antec or Thermaltake. Putting your money into a PSU that will last will make you much happier. Trust me.

Pros: Works just like it says. Plenty of plugs per rail.

Cons: took a little tweaking to get it to fit in my case just right and screw it in.. Could just be my case. not worth taking a egg off for that.

Other Thoughts: Wish i had waited a few days before buying actually.. price dropped 10 bux, and 1000W unit ended up being same price I paid for this one.
Rebate is somewhat of a pain to get with all they wanted for proof of purchase.

Pros: Stays cool runs super quiet for the price tag.

Cons: Non so far

Other Thoughts: Bought on budget happy so far!

Pros: +Provides power with good reliability
+When I bought it, it was the best bang for the buck from a company that sounded reliable.
+The short CPU power cable and long PCIE/SATA/Molex cables are nice for top-mount cases.
+ Good amperage along the 12V rails for my particular video card and CPU
+Coolmax has prompt and easy tech support. I contacted them with a concern that the fan blew out, and offered to RMA it within 2 hours. (However, after preparing to RMA the PSU and giving the PSU one last try, it worked flawlessly again.)

Cons: -This PSU has a bit of an identity crisis with its design. The fan is liable to get dust stuck in it in top-mount cases, but the cord lengths are really designed with a top-mount case in mind
-A bit concerning that the 12V rails are actually putting out a bit less than 12V, but I don't think that's a problem as the 12V rails aren't under full load in my system.

Other Thoughts: My build:
Coolmax NW-650B
ASUS M4A87TD/USB3
AMD Phenom II 965BE (125 watt version)
Rendition 4GB DDR3-1333 (x2, total 8GB)
Sparkle GeForce 560Ti 1GB
WD WD10EALS SATA HDD
An old Sony DVD burner
An old cheapo Ultra case

My system does crash from time to time, but the causes don't seem to be aggravated by the PSU. (One batch was driver related, the other batch was caused by glitches some old games have with newer shader models)
