FSP300-60GHS is a small 300 W SFX power supply from FSP targeted to small form factor (SFF) PCs. It measures only 5” x 4” x 2.5” (12.5 x 10 x 6.2 cm), while standard ATX power supplies measure at least 6” x 5 ½” x 3 ¼” (15 x 14 x 8.5 cm). The unit we reviewed came inside SilverStone Sugo SG05 SFF case. Let’s see whether this is a good power supply or not.
Our contact at SilverStone sent us an e-mail explaining that this power supply we reviewed and that comes inside SG05 is a little bit different from the standard FSP300-60GHS:
- Lower acoustics across all loading conditions
- SilverStone specific cable definition (type and length)
- Different +12V distribution through connectors to better support medium high-end graphics cards
Because its reduced side, it uses a slim 80 mm fan on its bottom. FSP300-60GHS features active PFC, allowing FSP to market it in Europe.
The cables have no nylon protection, and the included cables are:
- Main motherboard cable with a 20/24-pin connector.
- One cable with one ATX12V connector.
- One auxiliary power cable for video cards with one six-pin connector.
- One SATA power cable with three SATA power connectors.
- One peripheral power cable with two standard peripheral power connectors and one floppy disk drive power connector.
The number of cables is more than enough for building a small form factor (SFF) PC.
All wires are 18 AWG, which is the correct gauge to be used. The ATX12V and the video card cables measure 15 ¾” (40 cm), while all other cables measure 12” (30 cm) between the power supply and the first connector on the cable. On the SATA power cables there is 7 3/4” (19.5 cm) between the first and the second connectors, but only 4” (10 cm) between the second and the third connectors. On the peripheral power cable there is 7 ½” (19 cm) between each connector.
