80 Plus certification
Date Issued: 18th Nov 2010

Conceived back in 2004 and brought to market just a year later, the 80 PLUS initiative is one of many standards introduced in an effort to increase energy efficiency in modern technology. Targeting computer power supplies, it awards PSUs that are able to achieve an energy efficiency of over 80 per cent at varying workloads and a power factor of 0.9 or more at 100 per cent load.

300W Silverstone ST30SF Strider SFX, 80Plus Bronze, Fully Wired, Single (1) Rail, 1x80mm Fan, ATX PSU is rated 4.5 out of 5 by 12.
Rated 2 out of 5 by from Rubbish standby power consumption Uses 9 to 10 watts with the PC off. that's about 10 quid a year in electricity costs, while not powering anything. I have verified this is the case this with the motherboard disconnected from the PSU, so its definitely not due to the PC using the power and not really being switched off. Otherwise it is completely quiet on my PC which uses about 30W of power when not running apps.

Rated 5 out of 5 by from Small and effectively silent This power supply is installed in a new Media Centre PC for my lounge, so I wanted something quiet. This really is quiet, I've not heard it so far, and at the moment it's sat right next to me, not across the room. Evidently it will spin the cooling fan up if it is required. I didn't need anything very powerful, it's running an i3 6100T on a Gigabyte H170N-WiFi, an SSD, a 4tb HDD and a dual DVB-T2 receiver so 300 watts is plenty. Overall a nice piece of kit.

Rated 5 out of 5 by from Excellent piece of kit Once again an excellent piece of kit from Silverstone. Complete silent operation and with very good cable length. More than enough connectors for a HTCP build.

Rated 5 out of 5 by from silent operation After building a Mini-ITX PC with one of these, I was impressed by its silence. The fan does not rotate (presumably unless needed - I have not seen or heard it doing so). I bought another to silence an old mini-tower: Replaced the old hard drives with a 256gb SSD boot drive and 2tb 2.5" data drive; replaced the stock AMD socket AM3+ cooler with an old unused Akasa (socket 934 / AM2) cooler I had left over (the clips fits the same); and bingo! No more noise. I fitted a new 6-core CPU while I was at it. For office and design work, i.e with no discrete graphics card, the 300w PSU seems perfectly adequate.

Rated 5 out of 5 by from SilverStone SST-ST30SF SFX 300 Watt PSU Silverstone SST-ST30SF 300Watt PSU The first time I booted the pc after installing this PSU I thought it was broken as there was no noise. Complete silence what more could you wish for since purchase the fan has never run and nothing gets even slightly warm, the full ATX bracket is a bonus. I could recommend this PSU to anyone who likes silence and not the roar of cooling fans

Rated 5 out of 5 by from Does the job! I bought this as part of a HTPC I'm building. Does the job and makes less noise than the processor and case fan.
Date published: 2015-05-23
Rated 5 out of 5 by from Bought for a mini itx server My last power supply (a pico psu) gave way recently and i wanted something with a bit more power and the same quite running that I was used to. This psu is excellent, so far is has made 0 noise and as per my old pico psu all i hear is the Hard Drives spinning. So far it's been on 24x7 for the past 2 weeks without a hitch and the main fan hasn't came on once. Recommend.

Rated 4 out of 5 by from excellent little psu I purchased this for use with a new media centre and it is a very nice fit and silent. The reason for leaving a review is to highlight the lack of length on the motherboard cable and the sata cable. If these were a little longer the review would be full 5 stars.
