Image means nothing, need to read the numbers on the side of the PSU.
 
I dont have any numbers. Its PSU not my. Only a ımage. can i learn this capacitor?
maybe, if you can get all the numbers off the PCB.
 
There are many capacitors in a PSU. Do you mean to ask about its capacity? If you don't have a datasheet available, you need a PSU tester.
 
This is a really low quality PSU based on a double forward converter design with group regulation. Not something you wanna use in any modern PC.
 
That's a transformer, not a capacitor...
transformer, autobot, decepticon, go-bot, what's the difference?

so no Panasonic or Rubycon 105c caps and they are scraping the CapXon 85c discount bin? You figure the three year warranty in today's PSU market would scream quality parts.

A PSU tester? A PSU Tester will not tell you the capacity of a PSU. It will only tell you if the output voltages are present, and if it has a LCD readout, it might tell you the actual voltage values. A PSU tester is great at verifying a PSU does NOT work. But it does not present a full load for the PSU and will not measure current - both of which are needed to show wattage capacities. And it does not measure ripple or other anomalies. You need a sophisticated and dedicated PSU "analyzer" or a oscilloscope, and you need to apply a full load on the PSU to determine its capacities.

It may not be the best quality but I would not call it "really low quality". At least not from the data sheet. For example, you don't normally find 140mm, speed controlled fans in really low quality PSUs. And while 80 PLUS certification is NOT an indication of quality, to achieve at least 80% efficiency from 20 to 100% load does take a better design than a non-certified, "really low quality" budget supply.

And while I never base my opinions on user reviews alone, over 80% of 473 reviews at Amazon rated it 4 or 5 stars. I am NOT saying I would pick that PSU for any of my systems. But it does appear it would serve well for others less picky than you and me.

Tester, analyzer, whatever. You need a device that can show the capacity.

You are absolutely correct. I just want to make sure readers understand they can't go spend $15 on a "tester" thinking it will show their PSU's capabilities. There is a HUGE difference between a tester and an analyzer.

The OP pulled that image from the brand's web site so he already knows what they state (in marketing terms) the unit's total power is. I believe, and the OP can clarify, his question is what capacitors (brand, rating, quality, etc.,) are used in the build based on that image.

Hopefully they can indeed clarify.
 
Caps companies don't really have a trademark design/color combination that can be easily identifiable from ends-on view like this.

So yeah, let me switch into cap detective mode. That large capacitor on the primary side would be one of the easier to identify. There are three letters barely visible on the cap. It's almost certainly capacitor's series code. The first letter are either O, S, G or C. The second letter is H or U, although I might just see a bar in the middle which means it's "H". Third letter is R, P, or B. Capacitor is a 400V rating, most likely a snap-in. Consulting my BOM cheatsheet, one that stands out is ShelCon SHR series. It's a high voltage, high ripple, 105C rated caps, which are very likely to be used here. It also black sleeve and polymer body, so I have quite high confidence in that guess.

Now let's look at that off-green/gold color scheme on the secondary side. Considering the PSU already use ShelCon caps for the primary, there's a very high likely it'll use caps from the same manufacturer. Let's see what ShelCon offers. Unsurprisingly, their site is terrible with not much useful information about themselves, much less product datasheet. At least they have some fancy slides showcasing their caps. There's green-gold schemed SYJ and MHT series, but they're high voltage caps. Unlikely to be used in the secondaries.

Meh, IDK, electrolytic caps can come with any color scheme, even within the same manufacturers. It's pretty hard to guess what they're exactly without reading the markings. Tho, looking at the vents cutout pattern, it's pretty unlikely that they're Nippon caps (usually use Y-pattern), or Rubycon (usually use K-pattern). Not that it had any chance that the PSU use those caps just looking at the topology used anyway.

he knows what? that looks like an image from a phone. If he knew the brand why not post it? I see you posted a datasheet link, so where did you find that out that no one else could?

( when english is not the first language, its hard to figure out what any intends to say )

I image searched, he pulled the image off the brand's web page.
