Pros: There isn't much to say here. It's modular, has a quiet fan and works. I like the flat power cables. It makes them easier to slip around the back of the HDD rack in the case and keep them out of view.

Cons: The 8 pin CPU lead could have been longer. I was a little tight to run in all the way around the board to reach the plug.

Pros: When I put this power supply on the bench to test before I installed it in a friend's machine, the power levels were spot on, even under load. Any fluctuation was well within expected levels. I have no problems using this on future builds.

Cons: The 24 pin connector was a tight fit on the motherboard. I do not remove it except when a component dies so cannot subtract any eggs for that.

Pros: Black and quiet.

Cons: None.

Overall Review: Nearly silent and powering my rig fine for over a year. Running an AMD X6 1090T, and SSD, three HDD, and an HD6850. No problems.

Pros: very quiet. If the case didn't have lights, I would think the computer was off. It was easy to install and hook up the cables. Rubber gaskets fit nicely onto front and rear of PS to assist with the noiseless feature.

Cons: none

Overall Review: first time I built a PC (second time I installed a PS) and this item helped make the process as easy as can be while also creating a rewarding finished product.

Pros: Solidly built. It's noticeably heavier than my previous PSU. Love the modular system. There's a tight mesh netting around the motherboard cables that keeps them stiff and compact. Truly is *silent*. I'm shocked at how much of a difference there is between this and the "silent" Thermaltake PSU it replaced. To me, this feature is totally worth the extra money, even more so than the modular cabling. If/when I do another build, I will definitely be using another one of these.

Cons: The setup of the 20+4 power pin is kind of weird. The 20-pin part hooks to the board, but the 4-pin part does not. The 20 pin part is easy to tell when connected, but the 4-pin part never quite looks all the way seated. The SATA connectors require a huge amount of force to attach to the drives. Once they're in, the connection is solid, but I'm still in disbelief about how hard they were to connect. It wouldn't be as big of an issue if the plastic SATA connectors didn't have an extremely sharp edge. It's not sharp enough to scratch you outright, but it's the only place you have to get a tight enough grip on the plug to connect the power. I finished my build about an hour ago and my fingertips are still red and raw.

Overall Review: I would recommend doing a practice run connecting one of the SATA plugs to a drive before they're mounted in the case, just to see how much force is required. When working in a constrained space, it feels like you're going to end up snapping the connection, but once you do it a few times you'll know how much pressure you need to apply.

Pros: - Runs as quiet as the name implies - Modular cables are a godsend because my case is SUPER tight on space.

Cons: zilch.

Overall Review: I game heavily, have had this for a year no problems.

Pros: Truly delivers 600W. Will deliver 700W if you ask it to. Has over-current protection, so if you draw too much power it just shuts off (won't go up in smoke like most other low-cost PSUs). Truly silent. I can't hear the fan running at all. If I couldn't see it spinning I'd think it was broken.

Cons: None.

Overall Review: I just build a new PC consisting of the following: Asus X79 Deluxe motherboard i7-3820 overclocked 24/7 to 4.65GHz 16MB Muskin 2133MHz DDR3 Zotac GTX 680 Plextor M3pro 256MB SSD Dual Seagate 2TB drives (in RAID1) Blu-Ray burner and... this Silent Pro M600 Average idle power: 120W Typical load power: 280W Peak power: 380W Unless you KNOW you will be running SLI/Crossfire there is no reason to buy any more power than what this supply will give you. PSUs are easy to replace, so if you decide you need SLI/Crossfire later on you can always upgrade.

Pros: It works. It's also modular, I'm never making the mistake of buying non modular again. Nice packaging

Cons: Despite getting mine on sale, this isn't cheap for a 600w. I suppose you pay more thinking it's going to be more reliable. I hope that's true.
