SilverStone Element ST75EF is basically a Seventeam ST-750P-AF with a different cable configuration and rail distribution. Internally the two power supplies are identical.

Since we gave Seventeam ST-750P-AF our Golden Award seal, we don’t see why not giving it to Element ST75EF as well: it presents decent 83%-84% efficiency is you pull between 40% and 60% from its labeled capacity (i.e., between 150 W and 450 W). In fact Element ST75EF performed better than the Seventeam ST-750P-AF on voltage regulation and ripple and noise, plus it comes with more video card cables, allowing you to install two high-end video cards under SLI/CrossFire mode without the use of adapters – what doesn’t happen with the model from Seventeam.

Something really interesting is happening on the market right now. Both SilverStone Element ST75EF and Seventeam ST-750P-AF used to be sold for USD 130, however Seventeam ST-750P-AF price tag dropped to only USD 100, and Newegg.com provides a USD 40 mail-in rebate for SilverStone Element ST75EF, making this power supply from SilverStone to cost only USD 90 – which is a real bargain for a mainstream 750 W power supply.

Of course there are better products out there, but not at this terrific price tag.
