Question: Is a PSU included, if yes, what type/capacity?
Document: I checked, the plug, it is on the mother board and is tight. But if you just move the wire up and down even  a little, no light.And yes I did contact Corsair and no one every returned the call.
Only 2 minor issues I have with it. I have a 750 PC power and cooling PSU which prevented me from using a 140mm fan on the bottom intake.
Do yourself a favor and get a modular PSU to go along with this and you'll be very happy with the open layout.The case lights can be toggled and the built in case fans' speed can be controlled all from the front of the case.
All the cable management you could ever want, makes my build look great! I would suggest either a semi modular PSU or more patience than I had, had to squish the back panel on XD
You just set the panel on the bottom lip of the case opening and slide it in, tighten your thumbscrews and you're done.As many people have mentioned in reviews around the net, you WILL need an extension cable for your power supply. The PSU is on the bottom and most boards are configured with the power plugs on what will be the top of your board once you mount it.
I felt the extra's were worth the value over the 400r, vs buying them in addition to the base price of the 400.Filters are a problem in this case.The PSU filter is rather long and has to be removed straight out the back of the case, right where all your connections are. This is a pain, coming out the side would be infinitely easier.
(true cold air intake for optimum performance from the PSU).9. Bulges on side panels look great and add extra room for cable management - (I believe this is a must).10. Removable HDD cages. *I cannot stress enough on how important it is to research everything to the fullest before buying multiple component systems.
Why wouldn't a Corsair PSU line up with a Corsair case is beyond me. Poor QC maybe but still really?. Also if you have your psu drawing air from the inside be prepared to get creative when connecting the 8pin Cpu connector, I have to route mine through the hole above the PSU (one without a grommet) just to make it reach and even then it was a stretch.5. No side dust filter and proprietary fan wiring, really Corsair? Demciflex is perfect for the side6.
I really Like this Case. Everything fits well some the cable management options seemed pretty good until I found some the cables supplied with the PSU was not long enough to make best use of the managment arrangements. So why the missing star? I am having problems with the two supplied fans in the front of the case. When I first turn on my new computer all the fans in front where working. I turned the leds off as I don't need them and went on.
I bought a Corsair CX500M to use with this case, and I was disappointed to find out that the holes for the screws don't exactly line up. Two do line up, but the other two don't, and I was amazed to see that yes, it is the same brand, and no, they don't line up. I also had difficulty getting the side fan to work, but after I unplugged it and plugged it back in, it worked.
Answer: No. A psu is not included.
