Choosing PC power supplies & cables gets more complicated when the unit is used: the decision is not just whether the wattage and form factor fit your plan, but whether the condition is acceptable at the asking price. The Silver Stone SST-ST45SF puts a 450W SFX option on the table for USD 65.00, with visible signs of prior use part of the deal.
Quick verdict
The Silver Stone SST-ST45SF makes the most sense for a shopper specifically seeking a used SFX power supply with a stated 450W rating and an 80 Plus Bronze designation. Its USD 65.00 price gives the purchase a clear, fixed starting point. The key compromise is equally clear: it is a used unit described as showing scratches from earlier use, so it is not the choice for someone who wants an untouched-looking component.
Who it suits
This power supply is aimed at a buyer who has already narrowed their search to the SFX format and is comfortable selecting a used part. The listed 450W output is a concrete spec to match against the power needs of a planned PC configuration rather than a reason to assume it will suit every build.
It is less compelling for shoppers whose priority is cosmetic condition. Prior-use scratches are specifically expected here, making appearance a meaningful part of the purchase decision rather than a minor footnote.
What stands out from the listed details
Silver Stone SST-ST45SF 450W SFX 80 Plus Bronze Power Supply
The strongest reason to choose the SST-ST45SF is its straightforward combination of SFX form factor, a stated 450W rating, and the 80 Plus Bronze label in one clearly named unit. That makes it easier to decide whether its core specifications line up with the kind of power supply you are seeking.
The limitation is condition: this is sold as used, and scratches from prior use are part of its description. Shoppers looking for a clean exterior or a newly handled component should weigh that against the listed configuration before choosing it.
Meaningful trade-offs
The trade-off here is simple rather than hidden. You are choosing a used Silver Stone unit with a stated 450W capacity, not a purchase framed around pristine condition. The SFX designation is central to the appeal, while the prior-use marks are central to the compromise.
The 80 Plus Bronze wording may matter to shoppers who want that label called out in their power-supply search. Beyond that, the decision should stay focused on the named format, the 450W specification, and the used condition instead of assumptions about performance outside those details.
Bottom line
Buy the Silver Stone SST-ST45SF if you want a used SFX power supply with a listed 450W rating and accept visible scratches as part of the purchase. At USD 65.00, it is a focused choice for that narrow brief; cosmetic condition is the reason to pass.
