While this power supply is not going to impress our readers who have been following our recent reviews of the high end Corsair AX series, it is worth bearing in mind that this unit only costs £70 in the UK and is rated to the generic '80 Plus certification'.
Generally 80 Plus certified power supplies are meant to deliver between 80 and 82% efficiency levels, but we were pleasantly surprised to record efficiency between 84.62 and 86.78%. Obviously at full load it dropped down giving a final result of 82.02 percent, but this is still a great figure for a unit placed in this very modest category.
The use of high quality 135mm fan means that this PSU also remains reasonably cool at all times, and even under full load it is basically silent, living up to its ‘Silent Pro' naming moniker. People who are building a high quality media centre will love this design as it will add no noise to the system build. The fan never spins anywhere near the maximum rating of 37dBA.
For this specific user base this product is actually one of the best we have tested to date, and the fact that the pricing is now so competitive is the icing on the cake. When it was initially released it was selling for just under £100, its now £70.
KitGuru says: If you are in the market for a well priced power supply which is as silent as a sleeping monk then this should be high on your list of ‘shortlist' products.
Cant really knock that for the price, I love a silent PSU, some of the ones ive bought in the past have been loud as hell.
Very nice looking little PSU and more practical for most people. Ideal for media center, decent efficiency at lowist ouput and no noise.
Coolermaster make a decent little PSU, not in the same league as the new corsair stuff, but more than capable of giving enermax a run for their money.
efficiency is really good for the lowest rated cert.
My friend bought this last month for £90, he will be slightly pissed off 🙂 its a very quiet PSU and their naming is really honest. I like Coolermaster,
ideal for my next media build – might even drop a bit more by christmas !
really good value for money on the noise front alone.
Very good buy indeed. I had a coolermaster PSU before and I think its still working, its about 7 years old and very dusty ! well worth the money
I would buy this for a media center, but im aiming to pick up the 750W corsair unit which was reviewed here last week.
I find the internal design of this unit particularly interesting, the low profile concept with multiple capacitors.
