400W CiT Micro-ATX Quiet Fan 20+4pin ATX 12V with 80mm Temp Control Fan, PSU is rated 4.3 out of 5 by 4.
Rated 4 out of 5 by from Just the job Needed a slim sized PSU for an old SFF PC and this was just the job. Fits perfectly and has both old and new connectivity options.

Rated 5 out of 5 by from Great PSU Nice and quiet PSU. Fit in my micro ATX case no probs. Only thing that bothered me was the 4 pin ATX 12v lead was too short to reach the socket on my motherboard and I ended up having to use an extender cable, but no biggie.

Will this fit?!?

Will the PSU fit inside a Cooltek U1 case, The case specifies SFX but just wasn't sure. Thanks
Asked by: stoney102
Hello, This power supply (PSU) is a Micro-ATX form factor, whereas the Cooltek U1 case seems to only support SFX PSUs. Regards,
