Silverstone ST45SF, 450 W, 90 - 264 V, 47 - 63 Hz, Aktiv, 110 W, 450 W

Compact and well built, cool and quiet running unit

Fan is loud at higher speeds, but tolerable. SFX is extremely compact compared to ATX, and mounting it in an ATX case will create all sorts of awkward oddities with the SFX-ATX converter bracket.

I have purchased this from somewhere else and i noticed the rewiews on this product are a bit one sided mostly due to the supplier. This power supply is excellent if you are building a small mini itx computer or home server it is completely modular helping you reduce the clutter in the case and it can deliver a decent ammount of power. Now the cooling fan is a bit on the noisy side however if you have it hidden away or in the attic you will never notice.

Company that sells this is a joke. Advertised a used product and sent me a USB connector rather than psu, then sent back and got told I would get discount on new product as they took so long to return my money and then nothing. JOKE OF A COMPANY

First lets say, Do not buy from this seller Packetwalk Systems Ltd. I have emails that prove they are a bunch of liars, they sold me a faulty product and when I contacted to get it repaired they just told me no problem sent it back, spend £6 from my own pocket. They refund me (not the postage) saying that they couldn't repair it, silverstone couldn't do it and at last the product is not with us (i contacted silverstone and was told to rma it to the seller). Price went up, so had to spend an extra £65 to buy the same product again + £6.00 for the postage. Silverstone is not to blame but I don't know. Now the psu, it works, is good quality and being modular makes it easy to work with butttttt sounds like a hair dryer. It is noisier than the fans. Some people has been complaining about the same on the forums. Yes you can change the fan but that will void your warranty and if this one was from a bad batch i don't know.
