The SeaSonic Focus Gold SGX-650 SFX Power Supply Review: Seasonic Starts off SFX With a Stunnerby E. Fylladitakis on March 7, 2019 8:30 AM EST

- Focus Gold SGX
For the past several years, PC components have generally been getting more efficient and compact, allowing builders to create ever smaller and more appealing systems. The demand for compact gaming PCs is particularly high as, despite their higher initial cost, modern systems are more powerful than gaming consoles and have a significant number of other advantages as well.
As a consequence of that demand for compact-yet-powerful PCs, the overall market demand for high-performance SFX PSUs has been increasing as well, as top-tier graphics cards still have substantial power requirements. Although the selection of high-end SFX PSUs is not nearly as rich as that of traditional ATX PSUs, more and more high-end, advanced feature SFX PSUs are being released every year. And this boom hasn't just been the same few companies; even manufacturers who've traditionally focused on just ATX PSUs are now getting into the SFX market as well.
For today's review we're taking a look at SeaSonic’s latest advanced SFX PSU series, the Focus Gold SGX. The series consists of just two units: a 450W model and a 650W model. The former is ideal for systems with mid-range graphics cards (or less), while the latter can offer the higher power output required to handle top-tier cards and more exotic configurations. Along those lines, for our look at the Focus Gold SGX series SeaSonic is putting their best foot forward, having sent us their 650W model. With a $129 price tag, this PSU is still very much a high-end PSU for the SFX market, but is actually rather reasonably priced when compared to the other high-power PSUs it competes with.

Packaging and Bundle
SeaSonic’s packaging is aesthetically simple, with virtually nothing but text covering the front side of the box. There are some thin lines forming an abstract shape but they seem like a basic attempt to catch a shop-browser’s attention. Despite its very simple appearance, the box is strong and the internal packaging is excellent, ensuring the safety of the lightweight unit during shipping.
Inside the box, we found a rich bundle, especially for an SFX PSU. Aside from the regular AC power cable and the typical mounting screws, the company includes cable ties, three cable straps, and an SFX to ATX adapter. The latter is especially useful for users that upgrade or swap parts often, ensuring that their SFX PSU will be usable even if they decide to forgo their SFX design and build something else. SeaSonic even included a basic PSU jump-start adapter for users to test their PSUs without having to connect a system.
The SeaSonic Focus Gold SGX-650 is a fully modular PSU, so every cable can be detached, including the 24-pin ATX cable. All of the cables are ribbon-like, “flat” type, and relatively short when compared to typical ATX products. The shortened cables are the reasonable choice considering that the PSU is likely to be installed in very compact system where every millimeter counts, but their length is a potential issue for users wanting to use the PSU with a regular ATX case. Every cable is made of black wires and black connectors.

u.of.ipod - Thursday, March 7, 2019 - linkThis review needs to be updated to state this unit is SFX-L, not SFX. This unit will not fit in a lot of small form factor (SFF) cases that only accept SFX sized PSU, not the extra long SFX-L.
johnnycanadian - Thursday, March 7, 2019 - linkI don't think this one is SFX-L: this one is 100mm deep whereas SFX-L PSUs are 130mm deep. This one seems to be SFX through-and-through.
NateDawg72 - Thursday, March 7, 2019 - linkIt is definitely not 100mm, as stated at the top of the second page of the review and in Seasonic's specifications. It is 125mm deep
johnnycanadian - Thursday, March 7, 2019 - linkMy apologies! Yup, I see the extra 25mm in the specs; I misread the original. Bloody hell, this would have been a decent choice to drop into my 2400G-in-an-Apple-][-case project. Thanks for the keen eye!
Spoelie - Friday, March 8, 2019 - linkUse the corsair SF450 or 650 instead in that case
Samus - Monday, March 11, 2019 - linkI guess the real catch is this effectively becomes SFX-L after connecting the cables because the connectors and wires add about 20mm to the length, where a non modular design could have the wires sandwiched between an interfering component.
dromoxen - Thursday, March 21, 2019 - linkYep thats wht I was thinking , if you include the bulky connectors , thats maybe why modular FSX PSU should have some sort of flat connectors or have them indented (somehow).
Johhny Canadian ..650w , even 450w is too much for a 2400G , You'd get away with 250w or even HDPLEX 160w, surely..and unless you plan to light it up like leicester Square.?
dromoxen - Thursday, March 21, 2019 - linkAnd that lowered rating vs the op, temp is a bit sneaky ...
nevcairiel - Thursday, March 7, 2019 - linkThe first paragraph on the second page specifically calls out that its longer then normal SFX and therefor may not fit in some cases, FWIW.
Death666Angel - Thursday, March 7, 2019 - linkYeah, but there is a name for them and that is SFX-L as u.of.ipod stated. Makes it much less ambiguous.
