Packaging and Bundle


The ST35F is supplied in a rather simple yellow-black cardboard box. The PSU is not very well secured inside the box, with only a plastic bubble bag being its only protection after the cardboard box walls. The unit is fairly lightweight and that shouldn’t be a problem, unless the box receives a fairly strong blow during transport. The bundle is very minimal as well; inside the box you will only find a small manual and an AC power cable.

The Unit


Although the ST35F is designed to be a good quality high value PSU, aesthetics are generally not going to be given great attention, however, Silverstone have made a few adjustments in order to make the unit better looking than an OEM unit. The chassis of the unit is painted black and the 120mm cooling fan is blue. The matte black paint of the unit is not reflective but it also resists fingertip marks. The cables however are not sleeved, which is the most important aesthetic ‘upgrade’ for a PSU. There are not many cables and/or connectors. Besides the typical 24-pin ATX and 4-pin CPU power connectors you will also get 4 SATA, 4 Molex and 2 floppy disk drive connectors. There is no PCIe connector, which is a shame really as the unit is strong enough to handle a basic system with a mid-range video card with ease.


The bottom of the unit is dominated by the large 120mm blue-bladed fan. The rear of the unit is entirely perforated for the air to escape to the outside of your case. Only a small rocker on/off switch and the AC power plug can be found at the rear of the unit. The left side of the chassis is covered by a large sticker, naming the basic specifications of the unit and its safety approvals.



The interior of the unit is rather interesting. CapXon is the company providing the primary and most of the secondary capacitors found in the ST35F. Most of the capacitors are normal grade and rated at 85C maximum ambient temperature, but there are a few secondary capacitors which are rated at 105C maximum ambient temperature as well. However, what is most troubling are the heatsinks, if you can even call these rectangular metal blocks heatsinks. They are extremely simple with minimal surface area. Although the power output of the unit is low and the efficiency is high enough to ensure that there won’t be high thermal losses, slightly better heatsinks would be a great addition.
