HEC PSUs used to blow up 10 years ago (Thermaltake TR2 Units were infamous) but it seems they improved quality control/engineering.

JohnnyGURU (Established PSU guru/corsair employee) considers it passable and uses a similar (Not 100% the same) platform for the CX-F

The 550w G3 (Superflower) deal was better ($40), but this is probably the next best thing for the EVGA sale PSUs on amazon. Especially if you need 650w for an average "mid range" Ampere/Navi.

Avoid the GA Series. Has poor voltage regulation and fails at modern efficiency test according to him. G5 isn't bad, but the GT seems better due to modern topology.

In terms of "gold" rating... G3/G2>GT>G5>GA. Not sure where GS rates on a relatively scale. Haven't looked into it.

The Super flower units perform like a platinum PSU on certain samples according to cybernetics independent testing, but YMMV.

What does that even mean in terms of PSU's? Like girthier?
·
The temperature sensor might have been covered in s...t, but it won't make any difference since it's mounted directly onto the heatsink.

That's why I never listen to anonymous wannabe gurus.

Quote from Sam4u :
Good PSU if it fits your needs. If you are running 6+ cores CPU(125W +) and higher end GPU (3080 , 3090 etc.) you might need 750 -850 Watts or more PSU, depending on your system.
For a mid range system - ~60 watt CPU and mid range GPU this should be a solid choice.
I'd usually recommend at least gold PSU for efficiency and EVGA is a solid company with good customer service.
I was using multiple vendor tools for calculating power usage.

A 5950X, 3 Hard Drives (2 NVME), and a 3090 only amounted to about 580 Watts. At 90% rated, you could probably do fine with this. Sure more is always nice, but this isn't a slouch at all.

Power supplies aren't like processors. They don't get significantly better with every generation.

I know that but I also know with heavy use components in PSU can degrade over the years. Making it possibly not as stable under load. I typically replace a heavy used PSU on a new build if it's 5 years. But if someone wants to put a 5+ year old PSU in a expensive new build more power to them. I sure ain't, so the 7-10 year warranty wouldn't apply to me.

I'm a little ignorant about power, but doesn't a decent power strip keep you from dealing with excessive amperage in your system?

I'm a little ignorant myself. I've always heard components(mostly capacitors) in a PSU can degrade over years of heavy use. I would think that would happen regardless of how clean the power coming in was. Worn internals can lead to stability issues even if the power coming in the back is clean. Some experts that do know feel free to chime in.

Not an expert but It depends on overall heat of the unit. The bulk caps will get worse over time if subject to prolong heat exposure.

https://www.tomshardware.com/revi...193-4.html.

A 10 C change doubles effective lifespan of a 105c 2000hr Japanese main bulk cap such as nippon chemicon used in a lot of higher end PSUs from corsair, seasonic, superflower. Generally the go to brand/spec for these designers.

EVGA GS units were 2015 models (not the recent "outsourced" versions) about the same time as the G2's. HEC has not had nearly the track record no matter how you slice it.
EVGA G3 played games with the cabling to achieve the "stellar" results - something which came out in testing

Quote from Jsz0301 :
Being "Seasonic" doesn't make it better.. In fact a lot of Seasonic units are relatively lackluster in terms of specific performance metrics. You cant really judge a PSU based on brand these days. It's 100% about the platform used.

The older Seasonic focus gold line was/is a clear step down from G2/G3 in a lot of metrics.. Especially pre 2018 models and the GS seems like an even older platform looking at pictures (Maybe not even Seasonic designed since Aris never saw the platform prior, at least on 550/650w units.. 850w model is clearly a different beast.)

Edit: Just looking at the GS reviews should tell you all you need... Relatively poor ripple (550w/650w @100%). Double/Higher load regulation relative to G2/G3.. etc.

Least it has a decent efficiency curve like the G2/G3 on 115v (Again 550/650w)

The HEC GT is a clearly better unit (at least outside of eff. curve) and thats going off a cougar GX-F review with worse components.

All I can find is 2015 reviews of the GS 550/650. Apparently it's modified version of the older G series from 2012. They're likely closely tied to an original Seasonic manufacturing process while a lot of modern (Focus/Prime) units are generally outsourced for these days. Newer B12 Series is both outsourced for design and manufacturing by Helly.

Its not like the 650W Andyson GA or FSP G5 are a better option. The modified/upspec'd HEC TPK is considered quite decent relatively speaking. Track record or not, there are worse options. These are also now manufactured in Taiwan to avoid higher tarrif cost.

What bout G3 cables? Care to explain why it's not brought up anywhere? I see 18-22 AWG standard wiring with some random caps. No different than what other manufacturers do.

I'll admit that I saw early G2 samples having 16AWG wires, but EVGA did bait and switch around 2016 and downgraded the G2 to the same "worse" standard 18-22AWG cable as the G3.

The G3 was generally tested with the most basic cable design/layout on the market. G2 wasn't and had premium 16AWG wires (Even on 550w, likely skewing results) which ended up getting downgraded prior to G3 launch.


Honestly.. A lot of brands have better 18-20 or 18 pure gauge wiring on similar PSUs in the 650 gold/plat class. The G3 is on average a worse cable wise but still performs well.

The GX-F line (HEC TPK) was reviewed/tested with more premium 16-18AWG which is hilarious if you wanna bring up cable differences.

https://www.cybenetics.com/index....ams=1,0,29

Assuming theres performance benefits here, it just cements G3 being one of the best options EVGA had.

Edit:
Also note; GX-F is made in China, GT is Made in Taiwan. Two different factories building these PSUs, but share identical platforms.

Would I downplay the GT at MSRP? sure. But at 49.99? it's certainly a value.
