Energy efficiency certification

Seasonic markets the SEASONIC PRIME TITANIUM TX-1300 as an 80 Plus Titanium power supply. Certification is performed by an organization called 80 PLUS. But what does this mean “on paper”? It’s a pram introduced in 2004 to promote efficient energy use in computer power supply units (PSUs). Only products that offer more than 80% efficiency at 20, 50, and 100% load, and a power factor of 0.9 or more, are eligible. The PSU will waste 20% or less electric energy as heat, reducing power consumption and bills compared with less efficient designs.

80 Plus test type	115 V internal non-redundant					230 V EU internal non-redundant
Percentage of rated load	10%	20%	50%	100%	10%		20%	50%	100%
80 Plus		80%	80%	80%			82%	85%	82%
80 Plus Bronze		82%	85%	82%			85%	88%	85%
80 Plus Silver		85%	88%	85%			87%	90%	87%
80 Plus Gold		87%	90%	87%			90%	92%	89%
80 Plus Platinum		90%	92%	89%			92%	94%	90%
80 Plus Titanium	90%	92%	94%	90%	90%		94%	96%	94%

As you can see above, there are 80 Plus, Bronze, Silver, Gold (these three are from 2008), Platinum (2009), and Titanium (2012) certificates. As power consumption has dropped, most computers with a single GPU don’t need more than a 600-650 W PSU. The PSU tested today is the most efficient at 50% load (650 W), but the differences above and below this threshold are insignificant. You don’t need to keep it precisely at half load, but it’s best to stay below the maximum wattage for better noise performance, longevity, etc. The reviewed sample is 80 PLUS Titanium certified – up to ~94% efficiency @ 115 V (at 20~100% loads), and 96% @ 230 V – and has active PFC with a power factor of up to 0.99. It consumes < 0.3 W in its off-mode, complying with the ERP standard.

The actual results were possible to find on the 80 Plus website. Also, you can find the Cybernetics results here for the 1600W variant.

Technical Specs below:

Max. DC Output	1300 W
PFC	Active PFC
Efficiency	80 PLUS Titanium
Topology	Primary side: Bridgeless, Interleaved PFC, Full-Bridge & LLC converter Secondary side: Synchronous Rectification & DC-DC converters
Modular	Yes
Protections	OPP, OVP, UVP, OCP, OTP, SCP
Cooling	Hong Hua HA13525H12SF-Z (135mm, 12V, 0.5A, Fluid Dynamic Bearing Fan)
Semi-passive operation	Yes
Dimensions (W x L x H)	210 x 150 x 86 mm
Dimensions (W x L x H)
Weight	3.03 kg
Warranty	Twelve years

Seasonic Prime Titanium TX-1300 (1300W PSU) review
Today we’re putting the new Seasonic Prime Titanium TX-1300 power supply on our test bench. The company is mainly known for its PSUs (like Connect or Focus SGX), but we also already checked their two chassis (Q704 and Q503). Still, the high-end offer in the power supply range is the Prime series. The series debuted in 2016, but the TX-1300 and TX-1600 were released in July ’22. Both are not ATX 3.0 compatible (this will come in mid-December with a Vertex PSU family). Still, one of the new things introduced in the Prime Titanium TX-1300/TX-1600 (but also the 80 Plus Platinum compatible PX-1300/PX-1600 models) is the PCI Express® 5.0 compatible 12+4-pin power cable. Although the TX-1300 is a new PSU featuring two 12VHPWR connectors, it still isn’t ATX 3.0 compatible. You get a 16-pin capable of providing up to 600 W (12+4). So what does it mean exactly? Geforce RTX 30xx/40xx Founders Edition will work with Prime Titanium TX-1300 PCIe Gen5 connectors simply because they do not need more than 450W. The other versions of RTX 4090 – can get more than that, which should work too.

Seasonic Arch Q503 chassis + Connect PSU review
Seasonic company is known mainly for its power supplies, including the Focus (available in ATX and SFX factor), Prime (with the 80 Plus certificate up to Titanium), or Connect series. But that’s not all, as we already had a chance to check out their first chassis last year – Syncro Q704 with a 750W power supply. It has earned a “Recommended” award. It was an inverted ATX case, but we got something more traditional this time. It’s a Seasonic Arch Q503, which was presented in May ’22. This model should be cheaper; however, it was also designed more conventionally. It uses a two-chamber structure, with the mainboard tray sitting on the right side of the case.

Seasonic Syncro Q704 chassis + Connect PSU review
Seasonic company is known for its great power supplies, including the Focus (available both in ATX and factor), Prime (with the 80 Plus certificate up to Titanium), or Connect series. Speaking of the last one, they’ve gone further by introducing a chassis containing this piece of hardware – it’s a Seasonic SYNCRO Q704. But that’s not all – according to the marketing information, it really fits together, literally and figuratively.

Seasonic Connect 750 W PSU review
Remember that Seasonic Connect power supply? We have it on our test bench for a review today. It was finally introduced to the market on the 4th of March, after a long wait (they first presented it...
