Just the facts. Hopefully an isolated incident, but I will not be buying from them again.
Most computers only consume around 100-150w, and even a high end computer might consume maybe 200w. That's why most OEM computer manufacturers put small 250-350w PSUs in their systems. If you look at online reviews of highly overclocked systems with multiple video cards (SLI/Crossfire) they consume at most about 500-600w. Anandtech (a very trusted hardware review site) in a comparison of the ATI Radeon HD 4890 and NVIDIA GeForce GTX 275 (google it) also did a roundup of other comparable video cards and some SLI/crossfire setups. Their review system was a Core i7 965 @ 3.2Ghz (non-overclocked), 6GB of RAM, and SSD drive, and X58 based motherboard. Idle power consumption ranged from 170-260w, and full load from 260-420w.
The point is you don't need a 1000w PSU even if you have a high-end system. The wattage race is long over. A good PSU from a good PSU manufacturer is all you need. For regular desktop systems, a good choice is Corsair's 400CX or Antec's EA380. If you need a bit more power for an overclocked system, or multiple video cards this PSU is a great choice. Also for consideration in this price/quality range are Antec's EA650, SeaSonic's S12 and M12 550w & 650w versions, and PC Power & Cooling's 650 & 750w versions along with Corasir's own 750w version of this same power supply.
This power supply is also 80 PLUS certified, which means that it maintains at least 80% efficiency across a range of power usage from 20% of it's capacity (~130w) all the way up to it's rated maximum. This is *very* good. Most off-brand PSUs only make about 70-75% efficiency. This doesn't just make a difference in your electric bill (not much, but every bit helps), but it also means the PSU runs cooler since less energy loss during conversion from AC to DC. Generally speaking the 80 PLUS certified PSUs use better quality components to achieve the higher efficiency which means they are less prone to failure than the other cheaper brands.
In addition to having quality components, it also looks very good in the case. A very dark grey matte finish accented by yellow and black markings. The cables are long enough to reach pretty much anywhere. This is in my Antec 1200 full-tower case, which has the PSU at the bottom. The 8-pin motherboard power connector has plenty of room to reach the top of the motherboard. However, I had to run the cable the "normal" way over the video card and past the CPU fan since it was not long enough to feed behind the motherboard tray as I was hoping. Then there are 2 cables with 4 SATA power plugs on each, 2 cables with 6-pin PCI-e video card cables (each having an optional 2-pin attached for those video cards that require 8-pin power), and 2 cables with 4 regular molex plugs each.
Installation was easy enough. It was a bit tight trying to navigate cables around drives and fans in the Media Center. Overall though, it might have taken me about 30 minutes to get the old one disconnected and get everything reconnected to this power supply. This was also the first time I've ever tried replacing a power supply, so I took my time and made sure everything was exactly the way it needed to be. And I even had a couple of extra connectors left over in the end. Next time it wouldn't surprise me if I could do it in less than 20 minutes.
It's very quiet compared to the old one and I thought that one was pretty quiet. This whole experience has made me reconsider purchasing prebuilt computers. Seriously, if the power supply was that easy, why not buy the empty case and custom build the entire thing. Note to self.
Anyway, I couldn't be happier with the construction, installation, quietness, and everything else about this power supply. Like many other reviewing authors, I highly recommend it.
VERY quiet when not pushing it to the limits. Very well designed, NOT cheap components. This one keeps your mother board and devices SAFE and working right from problems that other power supplies create.
One note: the PS cabling is encased in separate mesh sleeves, another nice touch--and connectors are aplenty. One thing to keep in mind is that all these cables do take up space in the case, so unless you have an open bay into which you can neatly fold them, it could be a problem. The company does include small locking organizer wraps, which helps keep the cabling organized. Overall, this is an extremely nice product and well worth the price.
