Discussion PSU recommendations and power supply discussion thread - Tom's hardware

Context?

Attempt at a little humour.

I'll look into it. Never heard of Frontech before. @jonnyguru ?

Here is the PSU I was talking about. Its approx ₹1000-1100/$15
https://www.amazon.in/Frontech-Watt-SMPS-Power-Supply/dp/B07FZ1XDXB
It advertises 800W but outputs just 300W on the 12V rail, attached an image of the psu advertised ratings.

 

[King_V]

Well, it technically puts out a total of 480W on the two different 12V rails combined.

I'm guessing this is a VERY old design, given that it's offering so much power on the 5V (and to a lesser extent, the 3.3V) rails.

That the model number starts with "ATX P4 Power Supply..." makes me wonder if this thing was new back in the Pentium 4 days, and they were trying to advertise that in a way in the model number.

 

[Darkbreeze]

It is a very old P4 days model based on that. Plus, it's clearly been opened and damaged based on the bent frame. I'd highly recommend that you discard that unit. It isn't however enough, just based on the label, for me to want to add it to the "these are garbage" list of units because I just don't know enough about the brand in general to feel confident that it's the case. Now, if I could find evidence of several of their products being dumpster fire type units or all of the labels from several of their products not adding up to the listed, advertised capacity, then I'd think it could be included until some evidence suggests otherwise.

Would be a useful doorstop or fire starter for camping.

Doesn't weigh enough to stop a door from closing, I imagine there's barely anything actually inside it.

 

[Darkbreeze]

Some doors are pretty light, and well balanced.

 

[rounakr94]

I have one from 2013 that came prebuilt in their PC. Doesnt have any labels tho. Its works great for testing my fans outside of my case lol, sometimes I run my LED light bar with it

 

[Darkbreeze]

Well then, I guess I can't use my usual statement about "I wouldn't use that thing to power a light bulb" in this case.

An updated Corsair vs. interesting.

Now with flat black cables and a 600w output not 550 or 650.

And here's a CV with that same type of weird font* for the model number. What's the deal with these?

* reminds me a little of the numbers on the speedometer of my old 1984 Buick Regal.

 

[Darkbreeze]

@jonnyguru , are these new, or is this some kind of old stock with new stickers on them? ^^^^^

 

[NightHawkRMX]

There is a vs500 too

I don't think the cables are "new". Maybe a rolling change across the whole line up that never got reflected in the product shots.

500W and 600W are not a new PSU. Just 50W interval of the same thing.

You've seen a CV with a different font?

 

[Darkbreeze]

500W and 600W are not a new PSU.

So this:

Is the same as this:

It just has a revised label but same product? No internal changes?

Interesting twist.

The new VS600 is not the old VS600. It's just a +/- 50W version of the current VS. How about that?

 

[Darkbreeze]

Ok? LOL.

 

[King_V]

Hm, you know, now you mention it, I don't know if I've ever seen a CV at all. I just kind of assumed that they used the same font across all their current products.

 

[Rogue Leader]

Side note.

For Prime Day on Wedensday Amazon had under computers "deals on Corsair Power supplies".

You could get your hands on a Corsair RMx850 for the discount sum of....

$222!

 

[NightHawkRMX]

I think a CV650 was around $65 or 70, and a VS600 about $60. Not too bad, not great.

I picked up one of these, mostly out of shear curiosity. I have a new build with some rather nice hw that I needed a nice PSU for. We will have to see how good it is.
https://www.amazon.com/gp/product/B07NWZQX1J/ref=ppx_yo_dt_b_asin_title_o00_s00?ie=UTF8&psc=1
From what I saw after some research, its Andyson based with llc resonant and dc-dc, active pfc, 80+ gold, and all the power available on the 12v rail. Seems too good to be true for $55. I'm guessing similar to a Antec NEG 600w. The 3 year warranty is not good, but I will resell the PC without a warranty so that doesn't really matter. If it seems good once I open it up, I might buy some more of these for builds.

Someone bought one and opened it up and posted here: http://www.jonnyguru.com/forums/showthread.php?17849-Apevia-Prestige-Teardown

Does have DC to DC. A little anemic, but....

 

[NightHawkRMX]

For the price I could have gotten a CV450, and the Apevia seems better. And woah that PCB is tiny. Looks kinda gutless, though I don't think it is. Didn't get any close up of the capacitor brands in that.

I have to wonder if it can actually do 600W.

 

[NightHawkRMX]

Of course I don't have any way to test that, however I can try to load it as much as possible.

I'm using it with a 3600 (non oc a520) and a gtx1080.

 

[NightHawkRMX]

I could crossfire rx570s on it to find where the ocp is set but I don't want 2 dead cards.
