5 out of 5 eggsWorks for me

Pros: Guess the quality must be hit or miss, as I've had this PSU for just about 2 years to the day, no problems at all.

Cons: It is picky about the ps/2 connector (yes I still use a ps/2 keyboard on this thing). Some ps/2 keyboards will cause the LED to flash some sort of error when powering up, preventing POST. Remove the kb, turn on the PSU, then plug it back in and then boot.

Other Thoughts: Part of this build: 2x EVGA GeForce 9800GTX+ SLI, 1x WD SATA drive, 1x DVD drive, 1x Intel E8400 C2D, 2x2G PC8500 ram @ 2.0V all connected to EVGA nForce 750i SLI F TW.

1 out of 5 eggsBlew out my Motherboard

Pros: Lasted almost a month.

Cons: I have a Pci-Express Video Board that is operated off of the Motherboard. Power supply seemed Ok than I decided to add another fan. Guess it was the straw that broke the camels back because strange things happened and the next thing you know my Motherboard was not posting.

Other Thoughts: My guess is that the Voltage is divided among rails and even though my system probably wasn't using more than 400watts this usage was mostly through the Motherboard.
I've bought a COOLER MASTER GX Series RS750-ACAAE3-US 750W power supply and RMAd this one on day 29. Lucky. Reason I chose the CoolerMaster is that it's capable of 750Watt through the rail connecting to the motherboard which is what my system needs.

I don't know if others who have video cards powered through a power connector would duplicate my experience.

5 out of 5 eggsWorks Great

Pros: Love this Power Supply. It's the first one I've set up in 15 years. All the connectors are well Labeled. I didn't need the PCI Express Slots so just yanked them out. Great Cable management. It had all the right connectors.
I'm running
Asus M4a87/tdusb3 MB
Gskill 2x4 8gb Ram
Amd 6 Core 1055t
Corsaire H-50 liquid cpu cooler
Lite On CD/DVD Player
G.Skill 100gb SSD
WD 1tb hd
XFS Radeon 1gb Card that pulls 75 Watts under load.
It's handling it with Ease

Cons: Can't seem to find the LED light either not working or I had to put the supply on upside down. No Manual at all. But who cares the labeling of the cables was superb.

Other Thoughts: I just wanted to rush out a good review because I've seen some bad reviews. It worked great had all the right connectors well marked.

2 out of 5 eggs

Pros: Looks awesome. Modular makes the case cooler and more roomier.

Cons: Half the rails had no power.

Other Thoughts: Going to try and get a replacement from CS since even though the PSU is running at half power, it's still powering my gaming rig. Paid for 3 day shipping and received it in 7, not newegg's fault but still disappointing.

Looking forward to re-reviewing this product with 5 eggs.

5 out of 5 eggsBest PSU in the Price Range

Pros: It looks fantastic. The blue fan is perfect brightness. 4 12v rails for 60A+ of power is perfect for a huge HDD array build. The modular system is great.

Cons: I wish there were more SATA ended cables so everything matched. I now have to use the molex to SATA adapters to power all HDDs.

Other Thoughts: Overall great Power Supply

1 out of 5 eggsBad Main Connector

Pros: Looks great with modular cords and big power output
Good price

Cons: Main connector had one bad pin connection (-12v)

Other Thoughts: Thought the motherboard was bad because it would not POST after I switched out everything else and they worked fine. Turns out the computer I tried this PS in worked despite a bad pin slot on the 24 pin main connector. RMAed the MB but still no POST. Bought a PS tester and sure enough---all pins were good but the -12v

5 out of 5 eggsCool Blue Power

Pros: Modular design cleans up the case nicely. Blue LED's on fan match the rest of my case design. Powers all of my system with no issues and still runs cool.

Cons: Stock modular cables are a little tough to get where they need to go.

Other Thoughts: Runs my system flawlessly.

5 out of 5 eggsGOOD Power Supply

Pros: good bang for the buck. My first modular power supply and it is a hit! plenty of connections. Case is visually appealing and 120mm fan keeps it cool and quiet!

Cons: keep in mind if you get a case where the power supply mounts in the bottom that the 20+4 pin p/s cable will fit, but be careful it is a close, snug fit. not worth deducting an egg, just take your time!

5 out of 5 eggsIts very heavy

Pros: The 1st thing I noticed about this PSU after recieving it is its weight. If weight is any indication of quality this thing is super. Excellent finish and fit. Runs cool and quiet with its 120MM fan. Modular cabling keeps things neat and tidy. Has pleanty of power for my system.

Cons: None so far, love it.

Other Thoughts: My system: This PSU, Q6600 CPU,DFI LanParty DK X48,Vista 64 ultimate,4G Mushkin 1066, WD 640G drive,2 DVD burners,Noctua NH-U12P cooler( fits the board fine),card reader. Buy it now !

4 out of 5 eggsLooks Good Except DOA. . .

Pros: Very Nice Package & Product Finish & Decent Specs. . .
For the Price IF this P/S Had Fully Worked it Would be an Awesome Deal. . .
It Looks Like a High Quality Unit & Was Surprised to Discover it was Defective. Have Already Replaced with Another P/S so will be Returning This Unit. . .

Cons: Unfortunately this Supply was Received Partially DOA
( Dead on Arrival )
Supplied Enough Power to Light the MB Standby Light but NOT Enough to Fully Power the Mother Board
My Tech Estimate is the 24-Pin Main Connector is Problematic.

Other Thoughts: This Looks Like a 5-Star Power Supply and Appears Well Engineered & Is Very Nicely Finished. . .
May Try One Again as I Suspect that Receiving a "Bad" One is Not the Norm. . . Gave it 4-Stars Because it's Obvious the Manufacture put a Lot into this P/S.
