Extremely silent.
This power supply is incredibly silent. You barely can hear it spinning. The HTPC sits below my TV and I'm sitting in the dining room about 5 meters away and I cannot tell whether the PC is on or off.

Experience: 3 Weeks


+ Gives owners of "slim" computer cases an upgrade option
+ Decent array of connections for its power rating
+ Price won't break the bank
- Seems to generate a fair amount of heat
- Looked like it fell "off the back of a truck"
I have a Dell Vostro 200 Slim which I've performed several upgrades on over the years (gigabit E-net, Radeon 4550 video card, second HDD, etc).

The hard drive I use for my data kept suffering read/write errors, despite my replacing it several times (Oddly, the OS drive was never afflicted). Eventually, I concluded that my upgrades were stressing its meager 250W PSU too much and I temporarily remedied the problem by placing the second HDD in an external enclosure, but that was really annoying since I used the enclosure for troubleshooting other PCs.

Upon discovering the existence of the TFX format, I began looking for a new PSU. Honestly, I would have preferred a 350-400W unit, but this was the only one NCIX stocked. I couldn't see myself needing more than an extra 50W anyway.

Installing this PSU seems to have fixed the issues I was having with my HDD, so it was definitely worth the purchase. However, it seems to add a lot of heat to my system. The case is warm to the touch now where it wasn't before.

P.S. I don't know where NCIX got this PSU, but I got a real "fell off the back of a truck" feeling from it. The PSU had NO packaging other than a twist tie to hold the cables together. No box, no documentation, no specs, not even a plastic bag! Just seems weird is all.

Experience: 1 Weeks


Good price, works

I got this for a Dell Vostro 230 slim system that needed a bigger power supply when a low profile HD5570 video card was added. No problems yet.
