1 out of 5 eggsChinese psu

This review is from: CORSAIR CSM Series CS550M 550W ATX12V v2.4 and EPS 2.92 80 PLUS GOLD Certified Modular Active PFC Power Supply

Pros: Flat cables, semi modular

Cons: Extremely loud ramping buzzing noise after 30 days, chinese capacitors, exposed wires on the 30pin cable, stiff wires, no straight sata power cables

Other Thoughts: Rma in progress, unfortunate that i have to pay extra for something that should have been working from the beginning, last time i buy corsair for anything, avoid at all costs, go with xfx, seasonic, or evga for psu.

1 out of 5 eggsNot good for i7 4690K

This review is from: CORSAIR CSM Series CS550M 550W ATX12V v2.4 and EPS 2.92 80 PLUS GOLD Certified Modular Active PFC Power Supply

Pros: - Price
- Silent

Cons: - Computer will fail to POST while resuming from S3 sleep.
- SATA power cables too stiff.

Other Thoughts: Spent days swapping parts (memory video BIOS setting) in order to find root cause for S3 sleep issue. As the last resort I installed my 6 years old Antec 500W PSU. I didn't believe this new power supply can cause this issue, that was the last part to swap before the motherboard... Now what? I past the 30 days return period meaning I lost money on this one.

This review is from: CORSAIR CSM Series CS550M 550W ATX12V v2.4 and EPS 2.92 80 PLUS GOLD Certified Modular Active PFC Power Supply

Pros: Great, modular (semi) power supply. It is quiet and provides steady power to my new build. Enough power to run a solid system. It's gold certified, which is a good bonus.

Cons: None so far.

Other Thoughts: I'd buy this again without question. It's a terrific power supply.

5 out of 5 eggsI know nothing but this thing know more about power stuff than i do

This review is from: CORSAIR CSM Series CS550M 550W ATX12V v2.4 and EPS 2.92 80 PLUS GOLD Certified Modular Active PFC Power Supply

Pros: i know nothing about power, but this thing know some stuff about my PC, i put low cause i know nothing or how to test Power Supplies, you want that, check the big review sites, but this, this is you, but me, reviewing a PSU from Corsair. this thing if built like a rock, nothing bangs it, or even dings, the fan has a silent spinning mode, though nothing like be_quiet!'s stuff, but i never had them, but had the presence of one of their awesome power supplies, but this is a nice 80+ Gold semi mod PSU, though it would of been nice if the 3 connected Sata connector was more longer, had some minor clutter in my case but i have no way for going back like come do anyway. the braided CPU connector and 24 pin was VERY nice feeling and high quality, about the same size as the cheap as bottom PSU that was in there and i got it at a nice price at Cyber Monday, but it worked great and didn't need the Molex connectors cause nothing used it but SATA :D

Cons: only thing was that it had me confused which pins to put into my CPU header, as it splits for 4 pin (which i had a 4 pin CPU header) and the instructions didnt say anything that the LEFT 4 pins were the ones that worked....left me frakin worried that i didnt ground myself at the sink long enough.

1 out of 5 eggsVery disappointing

This review is from: CORSAIR CSM Series CS550M 550W ATX12V v2.4 and EPS 2.92 80 PLUS GOLD Certified Modular Active PFC Power Supply

Pros: No pros because it didn't work from the first place.

Cons: For Black Friday, I decided to upgrade my graphics card and ssd drive which required more power. So I decided to buy corsair 550w power since corsair is known for power making company. I was so excited when I started assembling all the parts. When I finished building my computer, somehow my computer refused to turn on. Since I had no back up parts to check out whats wrong, I had to go to computer repair shop to burrow their parts. As a result, I found out that the power that I just opened from the fresh box was malfunctioning which costed me 30 extra dollars for computer repair shop fees. It was really uncomfortable experience. I wouldn't buy from Corsair ever again.
