Not too long ago, we had a peek at a new unit from EVGA that used a brand new platform from Seasonic we'd never seen before. Today, we're looking at the EVGA Supernova 550 GS, the little brother to that unit.
I have to admit to being a little underwhelmed by the performance of the 650W version of this unit. Oh, it was decent enough from a performance standpoint, but when you're dealing with high end Seasonic builds after a while you tend to get used to stuff that has better than 1% voltage regulation and excellent ripple suppression. Then, when Seasonic floats a unit past you that isn't at the high end for them but still perfectly decent, it seems rather strange. Even so, we've only seen one unit based on this new platform until today. We still don't really know if the performance we got with 650W unit is what we'll get with all units based on this platform.
But we're certainly going to find out today.
Being based on the same platform at the 650 GS, the marketing on the box is all the same as well. Fully modular. TNB fan. 80 Plus Gold efficiency. 5 year warranty. It's all the same, except for the 550W specifications.
Let's quit monkeying around with the box and unpack now.
We get two bags of modular cables, a power cord, some cable ties, a self test adapter, a user guide, and a power supply. I see no screws in this shot... wonder if they forgot to add them.
The user guide is decent, and the same one from the 650 GS, so I won't bother scanning it again.
The ATX self test adapter. You can see where the metal bridge is located that shorts the PS_ON wire to ground, so the unit can be powered up without a motherboard. I find these particularly useful when bench testing some of my review units after taking them apart.
