Summary: I got the 900w non-modular unit. The price at $130 isn't very good, but Antec is a name-brand PSU maker. The fan is quiet. For a largish power supply, it has only 4 PCI-e 6+2 pin connector plugs. (two on each cable) This means you might have to use molex and adapters if you have 2 higher powered video cards. -1 star. You'd think for a PSU that costs this much, with this high of a wattage rating, it would have 4 separate PCI-e power cables, but that is not the case.
Summary: I originally had a 200wt PSU in my HP Pavilion, and after quite a few upgrades, it sizzled out on me. I replaced it w/ a Corsair 600wt after reading great reviews and hearing the praise that Corsair gets for their products. I had a totally different experience, the one I got sizzled out after only 3 weeks of mild use. That destroyed my opinion of Corsair, and will never purchase any of their products again. I replaced the Corsair w/ this 900wt Antec, and am very pleased.
Summary: This PSU worked great until it powered off due to overheating because it came with a dead fan :(. I have my PSU mounted fan down because my case has a dust filter for it, and my computer started shutting off randomly. I flipped over my PSU to discover that the fan wouldn't spin at all so I have contacted Antec and should hopefully get an RMA and get a good one here soon.
Summary: I would have given this 900 Watt PSU a five star rating except that the cables are very stiff. The wires are covered with a mesh fabric which would make one believe they should be flexable, but they are not. Other than that slight discrepancy the PSU maintains a very stable current which is good for overclocking and helping components to last longer. I have my AMD CPU which was running at 3.4ghz now overclock to 3.9ghz.
