Question: Will this work as an upgrade for a lenovo small form factor?
Document: All i can say is WOW! this is the little psu that could :-)I bought this because i am building a new htpc/budget gaming pc and needed a small form factor psu to fit in my Silverstone ml04 case.
I got this PSU for my mini itx build and the fact that its fully modular really really helps with tight spaces along with its small SSF form factor.The PSU is doing its job of providing power to the following components without any issues at all:EVGA Stinger Z77 moboIntel i5 3570KEVGA GTX 570a couple hard drives and a couple fans and I have no issues at all.
By the way, the airflow output is on par with the stock OEM fan. This DOES void the warranty and working on power supplies is DANGEROUS without taking proper precautions. Silverstone should really use a better fan in this power supply, but I am thankful they are pushing the limits of the SFX form factor.
Perfect SFX from factor 450W power supply.Very small but very powerful.Fully modular ,buy it you 'll not regret it, loved it
Replaced a 250 watt supply and was smaller. Great for my small case and powers everything great. I did like the bigger fan helped cool the case better.
This power supply works really well when I built a mITX rig for my brother. I haven't pushed it yet to hear if the fan noise is loud, but for it's small size it packs a punch.
bought this for a mATX system. it turned out to be perfect. it comes with a couple of adapter plates for different mounting patterns.pros: quiet, small, fully modularcons: motherboard power cord was too short to have proper cable management.
It's the only modular SFX PSU on the market today and i hope other brands will take notice (kudos to Silverstone for making this).ps: don't be afraid of the small watt rating, 450w is enough for most systems. Unless you run GPUs in SLI mode and/or do some extreme overclocking, you'll be fine.
I was after a small and quiet PSU. This thing is surprisingly small. Short cables are nice. At idle, I can only hear a slight rush of air. Under load, however, this thing is too loud for me. I just got finished playing State of Decay, and when I took my headphones off, it sounded like my box was going to take off. After a few minutes it quieted down again.
The power supply works great and is pretty quite, but you might want to skip if you want to put it in Silverstone's FT03 mini itx case.The modular sockets stick out from the back of the  casing and block the FT03 mini's HD bays. So you'll only be able to fit 1 HD instead of 3.Other than that, it seems to work great at providing power to a mini itx board with an i7 3770 and an NVidia 560 gpu.
Answer: Yes
