Seasonic Presents the PRIME Ultra Power Supplies
As graphics cards and motherboards become more efficient, their ever-decreasing power consumption has called for a new power rating variant. The introduction of the PRIME Ultra 550 W Platinum- and Gold-rated units is an answer to these current market trends.
The PRIME Ultra 550 W in many cases will even provide high enough power to reserve some headroom for future expansion. Customers will find new additions in the retail box of the upcoming PRIME Ultra Series.
- Seasonic has included a PSU tester in the box that will let consumers perform a quick and easy jump start on the power supply. When a system is not working properly, it can be particularly difficult to tell the difference between a faulty power supply and other components. With the help of the PSU tester, users will be able to verify whether the new power supply is working properly.
- Each PRIME Ultra Series power supply will also ship with a SATA 3.3 adapter to support the “Power Disable” (PWDIS) feature of the newer, high-capacity hard drives. This is an important feature for people who are planning to use the PRIME Ultra to power hard drives of a smaller-scaled server at home or in an office.
Some design updates of the PRIME Ultra power supplies further optimize usability.
- One of the most noticeable of the upgrades is that the inline capacitors on the cables were removed, which takes away from the bulk and improves cable management inside the system.
- The new 180 degree SATA connectors will ensure more flexibility and easier installation.
The exciting features of the PRIME Ultra Series can be summarized as follows:
- Ultra-quiet operation – thanks to the upgraded high-end capacitors and the quiet FDB fan driven by Seasonic’s Premium Hybrid Fan Control.
- Low ripple noise and clean power output – due to high-end components
- Compact size to fit smaller cases – 140 mm depth on the lower wattage Gold and Platinum units
- 12 years warranty
Please note that the exact release time of the PRIME Ultra Series varies per region and per wattage.

It's going to be enough for Vega for sure. My bet out of these 550W total of 535-540W are for +12V rail(s), probably it's a single rail PSU, dual-rail at max (knowing how Seasonic is doing their PSUs in 450-700W range), so 44-46 Amps or so total on +12V so it's going to be enough for even OCed Vega 64. Also I'm also 100% sure this Seasonig PSU under the hood has at least 650W rated electronics, probably even higher than that.
Only thing I don't wanna know about it is the price

The PSU tester is a great idea!
Also 550W is a pretty good choice for a gaming PC.
But yes, the price… hmm… Probably not cheap.
Also, the part about PC’s power consumption decreasing is unfortunately false…

It's a nice PSU but i'd prefer it in 650w flavor. 550 is a bit low considering you are prolly gonna use 300-350 and i like to use half the supply for max efficiency.

Efficiency will be within 1-2% comparing 50% and 80% so it really doesnt matter.
Maxing it out is a different story

Seasonic PSU of this caliber probably has the same efficiency doesn't matter if it's loaded 10%, 50% or 80%. It's their top of the line 550W PSU after all. Even "mid-range" class PSU from Seasonic, lets say some 620W, can easily match or even outperform most top of the line 650-700W PSUs from other well known PSU manufacturers. Call me a fanboy but it is what it is...
Wish I had the money to put adequate Seasonic PSU into every builds I own but sad thing is that here where I live Seasonic PSUs costs arm and leg, even mid-range ones. So far I have them two, both since 2011.
