5 out of 5 eggsI like it!

This review is from: Rosewill ARC M550 Continuous 550W@40 C degree 80Plus Bronze Certified, Modular design, Single +12V rail, SLI Ready, CrossFire Ready ATX12V v2.31 & EPS12V v2.92 SLI Yes Active PFC Power Supply

Pros: I bought this power supply because it was more than enough power for my build and the price was right. It's a modular design, so you could choose to either use some or all of the supplied cables or not. I didn't need a set but plugged them in and tucked them in the case so if I ever need them, I'll know where they are. Also, my case has a multi-compartment design, the power supply is in a compartment with the blue ray drive so it's fan isn't cooling anything else. The cables are sleeved for a good look and good air flow, It's easy to install the cables, they just plug in with a locking push tab.

Cons: I have no cons. A power supply is something I don't think much about, unless there is a problem and I have none.

Other Thoughts: I'd buy one again and would recommend it to friends, if any of my friends built computers (they don't).

5 out of 5 eggsnice PSU

This review is from: Rosewill ARC M550 Continuous 550W@40 C degree 80Plus Bronze Certified, Modular design, Single +12V rail, SLI Ready, CrossFire Ready ATX12V v2.31 & EPS12V v2.92 SLI Yes Active PFC Power Supply

Pros: I purchased this PSU for a new computer i am building. So far i have not done anything with it aside from installing it in to an NZXT 210 black computer case.

the highlights of this PSU are:
1. solid looking design
2. only have to plugin cables you plan to use.
3. price (got it on shell shocker after rebate will only be paying about have of original price)
4. 3 year warranty

Cons: Have to send in UPC from box to get rebate which is a shame as i had to mutilate the box to get the upc off. also using the rebate means i will have to contact the manufacture if there are any problems as i wont know until i finish building my computer which i am doing a few things each month.

5 out of 5 eggsgood deal

This review is from: Rosewill ARC M550 Continuous 550W@40 C degree 80Plus Bronze Certified, Modular design, Single +12V rail, SLI Ready, CrossFire Ready ATX12V v2.31 & EPS12V v2.92 SLI Yes Active PFC Power Supply

Pros: price, certified bronze, modular, all cables are black and flat, aside from the 24 pin, that's typical with sleeve.
3 year warranty.
43amp good 12v power

Cons: none yet.. only in use for a day.
only the 24 pin is sleeved, maybe a con to some. the rest of the cables look nice though. all black.. pretty decent for cable management.
