Well, remember: Brand doesn't matter.

EVGA has a lot of shitty PSUs on their lineup as well. For instance: N1, W1, B1, B2, B3, G1, G3(I'll explain that one), BT, BV, BR.

G3 I consider to not be recommendable due to two things: Iffy protections (OPP is set too high) and I've been reading various reports of them randomly popping.

Be quiet! has so many PSUs, I can't remember all of them

If we ignore Corsair's old PSUs (2014 and older) they have a solid track record. Only bad unit being the VS due to it being group regulated and an improperly working UVP.

In conclusion: Don't get a Seasonic Focus. There are better protected units out there. You can nab yourself an RMx, which is more silent and better protected. Hell, I'd even recommend a Corsair CX (2017) over a Focus. You also have the Bitfenix Formula Gold and Whisper M which are often in the 78-100$ price range.

Well, with a PSU, you really need to know what you're doing to repair one.

Corsair is pretty good with their warranties. Maybe try their RMx lineup. If you want to save a little money, their Vengeance Silver is an amazing unit for the price.

Alternatively you could go for the Bitfenix Whisper M, which is an awesome PSU, but I am not sure about how good Bitfenix warranty service is.
 

I'm afraid none of those will do. Try looking for a System Power 9, Xilence Performance A+, Pure Power 11CM, or a Corsair CX550. Those are the minimum PSUs I'd use.

Also, don't get a 1060 3gb. RX 570 is just as powerful as it and more often than not, it's cheaper. If it's cheaper, then go for it.

My personal picks are the Bitfenix Whisper M or the be quiet! Straight Power 11. Both are very solid PSUs and will have no issues powering the PC.

Another indication that a PSU is group regulated is to look at the power distribution label. If the PSU says it can output a total a 600w but the 12v says it only outputs 400w, then that's an indication that it's group regulated.

Here's some images which hopefully provide additionally clarity to those that don't know. 
There are two sides to a PSU. Primary and Secondary. Won't go into details on the specifics here, people like OrionFTL and JonnyGuru are better able to explain that if they wish. The two coils boxed in red are located on the secondary side. 12v and 5v are regulated on the bigger coil and the small coil has 3.3v. Now a thing to consider here is that there is a secondary topology known as Dual Mag Amp, which has two magamp coils. Better than group regulation from a performance standpoint, but in general, it's not very efficient. I think the most you can achieve is bronze efficiency. Maybe silver. It can be easy to confused the two topologies. Now, sometimes, group regulation could use one coil. I've seen a few very old PSUs with just the one coil. (credit to JonnyGuru.com for this image.)

Below is a Corsair CX450, arguably the best budget PSU on the market for most areas. Boxed in red are the DC-DC converters. Now, this example shows the coils covered. But usually, the coils are exposed and mounted a daughter board(s). These regulate the minor rail outputs while the 12v is independently regulated. I think it's regulated with a switcher or something. Near the transformer. (If someone could confirm, that'd be nice. (credit to Tomshwardware.com for image)

This is to the best of knowledge, so I hope this gains some insight on what to look for.

Several reasons.
 
for the old VS series (2012 I think?) it was a low quality poor performing poorly designed unit. Not sure on protections, but I believe it lacked some. It’s also group regulated. I’ve heard many reports of those things just Dying.
 
the new VS is better, but still not something you’d use in a gaming system. Office PCs, sure but nothing beyond that. Still group regulated and the OCP is configured to be way too loose. Allows the 12v rail to drop down to 11v, which isn’t good. Ideally you’d want go be between 11.6v-12.4v to stay within spec.
 
The old one is something to avoid entirely. The new VS can be used on PCs that draw less than 100w but I wouldn’t use it for more than that.
 
if you already have it, then yes, I do suggest a replacement.

Because ACRF (Active clamp reset forward) is basically double-forward but configured to be a bit more efficient. iirc, it's more difficult to achieve better performance metrics.

Double Forward whines and there's possible transient response issues when paired with high end GPUs. I have no idea if this was verified. I don't know if ACRF exhibits those same things.

I have been trying to tell them that for a month now.  It's dead reliable.  The AK47 of power supplies. Before it was a budget PSU, it was the unit you purchased to power SLI, Crossfire, Pentium EE systems, overclocked Thuban X6,  Overclocked Core 2 Duo's and Core I7's, overclocked Bulldozer FX chips, and everything in between, all of which drew a LOT more power than today's systems do. That's where its stellar reputation came from.  Powering hard core gaming machines for over a decade and powering them reliably, just like it does today. You can't fake that kind of performance or reputation. It may not be the best PSU anymore, but it's damn reliable. Most veterans know that already.   I suspect the problem on this board is a large number of posters in their teens and early 20's who know nothing about it.

Personal experiences don't matter with a PSU since PSUs are so inconsistent. Hell, you could probably find someone who says their EVGA N1 has lasted them 3 years under 24/7 use. Doesn't make that unit a good one. Then again, you can also find another person who says their N1 blew up. It's why these kind of statements are irrelevant.
 
If you already have the focus, there's little sense of buying a new PSU unless you want peace of mind, I guess.

https://www.jonnyguru.com/blog/2015/05/11/enermax-digifanless-550-550w-power-supply/4/ According to Jon, this thing has OTP.

https://www.tomshardware.com/reviews/enermax-digifanless-550w-power-supply,4125.html Aris says the same thing, it has OTP. I believe it even tripped while testing.

The Digifanless is a solid unit. Nothing really wrong with it.

It's normal for a power supply. Some models buzz more than others, and some particular units of a given model can buzz more than normal too. 

My bad, my brain didn't register that they were 1000w+ PSUs. That's more or less normal for high end units.

be quiet! doesn't really regulate the price IIRC. Blame Amazon. But my area of knowledge isn't how they price the units and such. Just the actual units themselves.

It's a bad PSU. Group regulated (Already bad) and OCP doesn't work right. Allows the 12v rail to drop to as low as 11v before being triggered, which is bad. Overall build quality isn't great, either. I definitely wouldn't pair it with a 2070 and 8700. Id' recommend you upgrade to a Corsair CX 550 or Bitfenix Formula Gold 550/650w (Ideally the forumula gold)

Looking around, I've compiled a short list of decent-solid PSUs from lazada.sg. I don't know what your budget it, so I'll just post a range.

My personal pick from a budget standpoint here would be the Vengeance Silver (I am not familiar with the currency, so I don't actually know if this is a low price.)
The best one from that list is the Corsair RMi, which is more than you need. If you want a heavy duty high end PSU:

You'll be perfectly fine with a 550w unit.

CPU draws about 120-150w at most and I believe that's it overclocked/
GPU would draw at around 250w.

So, peak loads would be around the 400w mark which is plenty of headroom and this is under a heavy load.

?!
 
a high quality unit would be fine. 
Many psu’s have zero rpm mode anyway and only spin up st a certain temp

Raidmax doesn't have any good PSUs out there. All of their units lack over temperature protection. There is one non-modular PSU I know of, but I  think its maximum wattage is 850w: Bitfenix Formula Gold.

Honestly, I wouldn't look at modularity, just look for a good PSU. The PSU's I've mentioned earlier are excellent picks.
