The ST50EF-PLUS is a 500W power supply with active PFC, dual 12V rails, dual PCI-e connectors, a 120MM fan and… supposedly… 80% plus efficiency.

SilverStone Element ST50EF-PLUS 500W

The power supply is very similar to the Enhance 400W I just recently reviewed. This is because this unit is built by Enhance and may actually be based on the Enhance ENP-5150 model.

SilverStone definitely makes sure we have plenty of connectors and, unlike the Enhance, most of them are sleeved.

* = 4-pin is obtained by using an included adapter.

 

Unlike most power supplies that feature a 24-pin connector with a breakaway 4-pin or a pair of 4-pin connectors that combine to make an 8-pin, the Element only has a 24-pin and an 8-pin. Adapters are included (see below photo) so the power supply can be used in 20-pin motherboards or boards that only require a 4-pin connector for CPU power.

The label on the box (above) has more information pertaining to the rails than the label on the power supply itself (below.) If we only referenced the label below, we wouldn’t even know what the combined 12V capability was.

The SilverStone Element 500W is one of the few power supplies we’ve seen where the two 12V rails are actually additive (18 + 18 = 36.) This power supply has a whopping 36A available on the combined 12V rails.
