CORSAIR HX series HX650 650W ATX12V v2.2 / EPS12V 2.91 SLI Ready 80 PLUS GOLD Certified Modular Active PFC Power Supply

Pros: Only had this in for a few days, but so far so good. Very glad to finally be using a semi-modular power supply so I can get all the extra cables out of the way. Since I'm not putting much load on it 90% of the time, the fan doesn't even turn on, so it's almost entirely silent.

Cons: While it is semi-modular (20+4 pin and 4+4 pin connectors are still pre-attached), the molex connectors are a little more than I need. I've got a few more fans in my case than my motherboard has connectors for, so it's a little annoying to have to try to hide half the molex cable while I'm only using two of the connectors.

Other Thoughts: Other than wishing it had molex cables with two connectors, it's running fine, running near silent, and has been reliable for all the load testing I've done. I'll post back if anything changes, but otherwise a good box.

Pros: 24 pin and 8 pin are long enough to route behind board. plenty of plug-ins. Good while it lasted

Cons: Only lasted a year.

Other Thoughts: My computer started giving me surge warnings on start up, then it would only turn on for a couple seconds then off then on. I tried different outlets and surge protectors. I ordered a new power supply and just replaced this one. Everything works fine now. I realize that components die but this was not a cheap supply so I am upset that it only lasted a year.

Pros: Price after rebate. Gold rating.

Cons: This PSU has a bad fan that chirps as it spins down, this is a common error noted by others. Also Corsair tech support is terrible, it takes them days or more to respond to a question. I would advise staying away from Corsair products simply because of the terrible service.

Pros: Great PSU. didn't have any problems installing it.

Cons: None so far,

Pros: Good brand name
Nice psu

Cons: Whistles when the fan changes speed

Other Thoughts: its a nice power supply but its really annoying when it whistles

Pros: Good cable management, probably quite reliable. Has been in the several months I've owned it.

Cons: My specimen began exhibiting the dreaded bird call about two months into ownership. And that's exactly what I thought it was... a bird outside my window. At least, at first. And because it only happened every several hours at best, I didn't decide to look into the noise until recently. Once I did some research I found I'm not the only one.

Now the noise now occurs every 10-15 minutes. And the warranty has expired. This is a decent p/s and was recommended at tonymacx86 for a Hackintosh build but I won't recommend it unless you're using in something like a data center. If you use your computer as a HTPC or perhaps as a DAW or anything where noise levels are critical, the chirping will drive you up a wall.

Other Thoughts: Get The SeaSonic X650, which also comes with modular power and doesn't exhibit a cooling fan that chirps like a bird.

Pros: Cable Mgmt is nice

Cons: This thing sounds like a monkey or bird is living in it. Just built it today and it started after running a few minutes. What a pain to replace (RMA) it now that I have the thing built. Wasted hours of my time!

Pros: The pros to this power supply quickly flew south once i powered it up.

Cons: CHIRP, CHIRP, CHIRP your way back to new egg little bird. RMA after 2 hours of use and ready to pull my hair out. Between a friend and myself we bought 4 of these, 2 if them CHIRP!!!! It's a coin flip if you're going to have to return. NOT WORTH THE RISK OF PURCHASING!!!!

Pros: Very good build quality and packaging. Also modular which is always a plus

Cons: None so far.

Pros: This is a great PSU.
I'm probably pushing around 700 watts though this thing daily with my Crossfire HD 7870XT's maxxed out 1200+mhz each and my i7 3770k OCed pretty hard. Along with a few other items I have running in it. and it takes it like a champ.

Cons: Little high in cost now, but well worth it!!

Other Thoughts: Got it on a deal. So it was worth it to me.
