This review is from: DFI LP DK 790FX-M2RS AM2+/AM2 AMD 790FX ATX AMD Motherboard
Pros: Diagnostic LED, good features, overall. Probably a great motherboard when it works. Works with Ubuntu (I run Intrepid Ibex 64-bit). Performs well.
Cons: My first one died after a week and Newegg was awesome and returned it quickly. My second one died a month after arriving. Now I'm dealing with DFI for RMA and they're rude and unhelpful.
There were also a lot of stupid bugs. For example, the motherboard won't boot when my IOGear GCS1764 is plugged into it. It'd throw a USB device error. Dozens of other systems have no problem with the KVM, though. I didn't have my motherboard long enough to troubleshoot it and look for a solution.
I run Vista 64-bit and Ubuntu 64-bit. Vista can't shutdown properly. It'll shut down and then post C1, a memory error. I then have to unplug the power cable and then it'll boot just fine. The problem doesn't occur in safe mode or Linux. I am using good OCZ Reaper memory modules. I've installed the latest drivers from their sites and reformatted my OS to make sure no old drivers were installed.
Other Thoughts: The SATA ports are awkward and don't accept cables with clips...without forcing them in and hoping they don't pop out (the springy clips on most nice aftermarket SATA cables put outward tension on cable, making them come out easier than normal cheapo SATA cables) .
I didn't personally like their overclocking software. There's no BIOS mode wizard for % overclock like most companies have. You have to either use poorly documented Windows software or set all the settings manually.
DFI's RMA and tech support are jerks.
I probably will never buy another DFI board again. They're unhelpful and don't take any responsibility for finding a solution. They keep blaming someone else for their boards having electrical failures and their driver bugs.
If your product either doesn't even power on or doesn't work in Windows, how can you blame other people? How can a motherboard company not take responsibility for their products under those scenarios
This review is from: ZALMAN ZM850-HP 850W Continuous @ 45°C (Maximum Continuous Peak: 1050W) ATX12V V2.2 / EPS12V V2.91 SLI Certified CrossFire Ready 80 PLUS Certified Modular Active PFC Modular Heatpipe-Cooled SLI Power Supply
Pros: Very quiet.
15% more efficient than my old high-end PSU.
Has fixed cables and modular ones. Has one fixed molex and one fixed SATA strip (exactly what I need).
I couldn't have asked for a better PSU. This one is perfect in every way.
Cons: This PSU is huge and heavy, so make sure you have room.
It has dual PCIe power cables when I only need one.
Neither are concerns to me.
Other Thoughts: I have a high-end 5-year old 480w Thermaltake PSU. I replaced it with this PSU and it was noticeably quieter and at least 15% more efficient according to my Kill-A-Watt. There is one strip of fixed molex and fixed SATA power cables as well as 2 PCIe cables. The rest are modular. I love that design, but others have complained about it. The non-modular cables are a trivial bit more efficient than the modular cables.READ FULL REVIEW
Pros: Low noise, modular cabling. Would be a perfect PSU if it actually worked.
Cons: This power supply makes the power go out in my home office. It also cannot shut down properly. I bought this power supply to replace a Thermaltake 480w PSU for a future upgrade and to tidy up my box. I have a 15A breaker (new home). When I hit the power button to shut it off, the breaker flips. When I shut down via Linux/Windows, it never actually shuts down, just reboots. My only option to power this down is to flip the switch on the back of the PSU or unplug the computer.READ FULL REVIEW
