Pros: 4 Modules, 8 Integer Engines. See, no where did I say 8 cores, lol, ok moving on. The fact is, there are 4 full cores, and 4 secondary cores. Each of the 4 modules has a a full core and a 2nd core, think of it as Hardware Hyper threading. If you set it up correctly it will run decent, but will never surpass the Intel Sandy Bridge CPUs. Scales really well with Overclocking. I can Run 8 Worker Threads in Prime95 and Still Watch HD Flash Movies online. Cinebench scores me at 5.06 on Default CPU/BIOS Settings. For $200 if you want the ability to do multiple CPU intensive things at once, its a good deal.

Cons: Still not on par with Intel, but that keeps AMD from charging more for the cpu. Load Balancing has threads bouncing around cores instead of staying on one core. Power saving features cause some delay in CPU functions when going from 0% Load to 60%+ load (CPU has to unpark cores, and change multiplier.) Some games dont push cores enough to kick it out of the 7.0x muliplier power save mode, so game shows delays in CPU oriented functions. When Overclocking, Power Consumption is an issue, as well as V-Core voltage/stability. Even w/ 4.0Ghz Stock Turbo Core, Single Threaded Applications struggle to compete with Intel.

Overall Review: If you can wait, wait for PileDriver this summer. Tweaking for "General" non overclocked performance had me in the bios constantly changing settings in regards to: APM, TurboCore, Voltage, C6 State, C1E State, Cool N Quiet. With certain features on, cores are parked, while others drop to like 1.7Ghz (7.0x MP), so when you first start using it, you have to wait for it to unpark cores, get to Stock Clocks then to Turbo Clocks. When Using all 8 cores, my CPU Turbo's to 3.4Ghz momentarily before dropping to 2.9Ghz (14.0x Multiplier), then back to stock MP, then back to Turbo, Possibly a VDroop Voltage issue. When using 2 Cores, Max Turbo is 20.0 Multiplier @ 4.0Ghz. I get better benchmarks when disabling turbo core and power saving features, and forcing a 4.0GHz Base Overclock w/ Voltage increase. Idles 5-9^C on H100, Loads 17^C Mainboard: ASRock Fatal1ty 990FX CPU: AMD FX-8120 CPU Cooling: CORSAIR H100 (CWCH100) Memory: G.SKILL Sniper Gaming Series 16GB DDR3

Pros: Worked Great, Silent, Modular, Etc

Cons: Ran if for less than a year, and a month or so break while I was waiting for a GFX Card to be RMA'd. Suddenly we heard a POP and the System shut down (while Idling.)

Overall Review: Doing a lil investigating before I contact RMA in regards to why the unit failed.

Pros: Modular, Well Built, Plenty of 6+2 PCI-e Cables, Silent, 80+ Gold, 8-Pin 12v and 24 Pin ATX Are Decent length., Plenty of AMPs Another Case sticker for my collection.

Cons: -Umm, No actual instructions that I could find in the box, Not an issue for me, but some with lower tech level would end up having to guess what goes where, even with the labels printed on the connections. -Not sleeved?, but who cares? the Cables dont have individual loose leads. there's no need for them to be sleeved. I'm straining to find cons.

Overall Review: Upgraded to this one because my cheaper 700w didnt have enough Amps to run Dual HD7900 GPUs, Let alone the PCI-e Power Cables, This unit had plenty of AMPs on the 12v rail, plenty of cables, and the 12v CPU cable was significantly longer, which also helped, with my larger case, My old PSU Unit I had to pull the 12v Cable kind of tight to connect it. No problems with the RM850! Windows 7 Ult 64, HAF922, FX8350 @ 5.15GHz H100 Cooled, 16GB DDR3-2133 GSkill, R7970 Lightning + DualX HD7950-OC XFire @ 1.1/6.0GHz, Creative XFi Plat.

Pros: - 6 Screens from a Single Card -xDMA Crossfire -Graphics Rendering Power.

Cons: -Heat Management Profiles -Downclocking due to the Passive Profiles.

Overall Review: @skip2malu, R9-290s use bridgeless crossfire via xDMA, (with Other R9-290/Xs). R9-280s can XFire with 7900 Series GPU's, So if you had one, you can XFire with R9-280 One R9-290 supports 6 Screens from a single Card, 3 from HDMI/DVIx2, 3 from DisplayPort-> Display Port MST Hub. The Stock Profiles for these cards allow the Temp to rise, Ramping up the fans do wonders in keeping temps down and GPU clocks up. Out of the 4 cards I've tested, Sapphires TRI-X has the best Cooling by a large margin.

Pros: Allows me to Easily swap out my SATA Drives Instead of Shutting down, opening my case and replacing them and closing the case again and booting back up.

Cons: -The 5.25 Bays of cases usually dont have cooling, so be prepared to mount a Fan above / below / behind / side of the Bay or temps will be a concern. (50 Degrees Celsius is enough to damage a HDD) -Works better with SCREW IN RACKS, these slide and clip in plastic clamp racks will have issues. (I personally removed the push button clamps on my HAF 922 to off the best solution.)

Overall Review: I have 3 of these, each cooled by a 120mm fans attached to the bottom or back. 3TB Drives work fine, If you have issues, Read your Mainboard manual, If your are forced to Use a 3TB Drive divided into 2 Smaller Partitions is a Mainboard HDD Controller Issue or a Windows Issue. This unit simply acts as a Removable Bay with a Power On/Off Features, You slide the drive in, and close the door, turn the key, let it spin up and windows detects and installs the driver for the Actual HDD. (WDCXXXXX etc), The Max Storage Limit is determined by your Harddisk Controller or Your Windows/OS Version (32-BIT O/S's Support a Max Partition Size of 2048GB or 2TB) Also Note, for it to work correctly, you need to have a Mainboard that supports AHCI Mode, and it should be enabled.

Pros: Used this drive in a Build for my brother. Fast, Responsive, SATA6GBps,

Cons: Maybe they get a lil warm under load.... If it works as expected there's not really any cons.

Overall Review: Not knocking any eggs, the drive was fantastic, Just Failed after being bought on 1 / 6 / 2013, and if it can survive my brother's downloading and gaming habits this long it deserves a medal. Windows Slowed down to a Crawl, so brother shut it down, I came home to Test, Windows wouldnt boot. (Black Screen with Mouse Cursor) I Used my rig to scan the drive and every 20 or so minutes it would soft-lock the Virus Scan, and put some ATAPI errors i my windows logs. Then Resume Scanning. Virus Scan found Nada, Permissions for Folders were all correct (so no ZeroAccess Virus). SMART Stats are Green/OK, But it Wont Run the Quick Test. Im thinking something in the drive went poof. When It Soft-Locks the Virus Scan, it does NOT make any abnormal sounds. In fact it's a bit quiet, I can hear the motor running if I listen to it in the case, and can feel it reading/writing.
