Summary: It seems to be working fine in my brothers pc. Being modular came in handy, since it's just an HP Pavilion case with no cable management options. Kinda feels cheap, and lightweight to me. I usually prefer Fractal Designs power supplies, but in this case, needed a cheap modular solution in which Fractal doesn't offer so I went with Corsair.
Summary: I have a lower power rig that this powers just fine. I have played new computer games with most of the settings on and it went just fine. I would by it again. The modular aspect is nice for a small case like I have.
Summary: Not many reviews on the web but loads of reviews on Amazon told me this was the PSU for my needs. I have a single GPU and a cool-running Core i5 Haswell CPU, so I figured it wouldn't load it much. And it doesn't. The loudest thing in my system is the case fans and they run very quietly. Would recommend for a similar build. The main 24-pin and aux 8-pin cables are not modular but if you're building a PC you need those so why would you want them to be removable? Great PSU.
Summary: Needed that second SATA because of distance to a new device to be added. Couldn't find it (modular, unused, stored). Inquired how to buy a replacement, thinking perhaps it was originally missing.
Pros: Very quiet, stable power. Good build quality.
Cons: MB power can be a little thick for routing. Still, got it to fit behind my MB tray in an old Antec PerformancePlus 660 mini tower case. Newer cases are better designed for routing.
Summary: My CX500M is very quiet at idle, but under gaming loads (i5 4670K + GTX 760), the PSU fan whirrs up and become the single noisiest component in my build. By comparison, my older PC P&C Silencer Mk III 550W unit is much quieter under similar loads, and that's even with my Corsair unit in a padded case and the PC P&C in a non-insulated case. Would recommend this for low-powered builds only, for which it is a great option.
Pros: Modular, quiet at idle and low load. 2x8-pin PCIE power plugs. Single 12V rail. Haswell-ready.
Cons: Noisy under heavy load (~300W est.), could use a couple more SATA power plugs.
