Info EVGA GT 650w 80+ GOLD Teardown

[NightHawkRMX]

This power supply was $44.99 with free shipping refurbished the other day. Surprisingly, I had enough self control not to buy it, but a friend of mine who was in the market for a decent standard length PSU did buy it and took some photos.

From what EVGA says, it looked promising.
7 year warranty
Full Japanese capacitors
50c rated
Full set of protections including otp
Fdb fan

Any clue who the OEM is?

Very odd layout to me, definitely not a platform I am familiar with. DC-DC boards are pretty prominent at least, but overall odd layout.

No photo of the underside of the PCB, but with the jumpers I see, it looks like a single layer PCB.

I would hope its doesnt have a green label to differentiate it.

Huh ... that's why i keep seeing that supposedly discontinued series still in the market. Is it, like, completely identical externally to the GW's CS-M ?

Nope. It's just a recycle of the brand name. The GW unit is completely different then HEC.

 

[jonnyguru]

If Corsair released that current gen CS-M over here and it were to be a similar price to what the GT650 often sells for ~$75 I think it would sell decently well.

You have to consider that's an unrealistic sell price based on current market situation. EVGA is strong arming distributors to buy a PSU with every graphics card or they don't get graphics cards. Since graphics cards are in such high demand, they're taking EVGA up on their offer, buying a PSU with every graphics card, then flipping the PSUs as quick as possible so they don't sit on a bunch of inventory.

This doesn't happen in China.

Hmm, so can you show how it looks then ? Can't find anything looking not like the old CS-M, neither any recent reviews of it. And Corsair site in Chinese doesn't help either.

 

[NightHawkRMX]

thats true. maybe corsair should start making graphics cards 🤣

 

[NightHawkRMX]

there is a g5 650w for $60 ln Amazon. so at least there is some benefit to this gpu shortage.

Which is really just a G1+ with extra steps, 60$ is a completely normal price for it IMO, not ~100$ it usually goes for.

Yes and yes.

This unit keeps going down and down in price on Amazon. It is insanely cheap right now.

GT650 is $50 New sold and shipped by Amazon.
Amazon.com: EVGA Supernova 650 GT, 80 Plus Gold 650W, Fully Modular, Auto Eco Mode with FDB Fan, 7 Year Warranty, Includes Power ON Self Tester, Compact 150mm Size, Power Supply 220-GT-0650-Y1: Computers & Accessories

Additionally GQ650 for $45, G3 550w for $40, B5 650w for $40. Tons of good deals. At least that benefit came from the GPU shortage...

At least the GT is somewhat decent. I would not recommend the GA or GQ to anyone, though. Surprised they still have G3. Thought EVGA burned their bridge with Superflower a long time ago. Then again, they burned their bridge with Seasonic and still managed to convince them to make the G6.

 

[NightHawkRMX]

My i7 990x + GTX590 system is happily running on a GQ850w. The review over at your site seemed positive on most things except pricing so...

B5 seems decent, although the review I saw was not very in depth. Have you done any testing on it?

 

[maxamillionfeettall]

Yeah, I was trying to convince my self not to get the $50 GT.....I folded at the 20hr mark lol.

I didn't write that review. And that review was written before problems using an ACRF platform with Ampere cards reared its head.

I also bought one, so I would have a spare PSU.

Actually, it seems that they still sell even G2 and P2. The latter is okay, they don't have a replacement for it, but how the hell they apparently still manufacture both G2 and G3 ?!
I suspect that's reburbished stuff being sold as new ... Or they've manufactured so many of them that there's still something to sell in the vaults lol.
PS: Also, damn, 50$ ?! That's really damn cheap ... I don't need a new PSU but, it's hard to convince myself not to buy it lol.

I have no idea. Obviously, I'm going to be extremely suspect. But I think because I know how the sausage is made, I reserve the right to be suspect.

I'm thinking either refurb or, more likely, it's not actually built by SuperFlower.

 

[maxamillionfeettall]

Oh no, I hope it's not another rosewill scenario of re-using a model name with a totally different oem.

 

[Karadjgne]

Depends on the platform doesn't it? If it's an Evga platform, any OEM could build it, but if it's an OEM platform, it'd have to be different regardless of model if built by someone else.

But there's no such thing as an EVGA platform. 😀

 

[NightHawkRMX]

Honestly, what was the agreement when EVGA dropped superflower? Do we even know?
