Inexpensive SFX PSU which does the job
Purchased as a replacement PSU for an old Netgear ReadyNAS Ultra 6, which had a Seasonic SS-300SFD PSU. This item fitted perfectly and works fine.One unknown for me was how many connectors of different types this PSU has. I needed three 4-pin MOLEX and fortunately it had four of them. I've uploaded a photo of the info from the side of the box.

Does the job
Good price and easy to install in place of the defunct unit. I now realise the old PSU was probably quite expensive and designed to be quiet. This one is cheap and works, but the fan is quite noisy. Still, it brought my ancient PC back from the dead and I suppose a noisy working PC is better than a quiet dead one!

Fit for purpose and good price...
This was a replacement for the same part on my HTPC (Home Theater PC), when the old one died when i was tinkering with it! This fits the case properly (not many mATX PSUs around) and is quiet enough. The fan spins up when temps increase, but that's to be expected really. All in all fits the purpose for a great price.

My advice? Don't buy it!
I ordered this nearly 3 years ago for a small pc to host game servers for me and my friends. My advice? Don't buy it. For one, the fan is TOO noisy. There is barely any temperature control system in this psu and it runs at full speed all the time. Sure, it did last me for a few years but the fan bearing is starting to come off because it made a horrible screeching noise when I turned it on the other day which shows they use cheap fans. Glad to get a new one to be honest. Its also risky, given the fact there is barely any contact information regarding warranties and the fact it is really cheap. For efficiencies, I believe it is around 75% which means it can get very hot during high loads. All in all, don't get it. It might be tempting because of the price but don't risk damaging your system!

Works as expected
I have been using this power supply for two months now and it runs silent and reliably.

I had to replace the fan because it was driving me crazy I will get a new quality one as soon as I can.
