PSU Recommendations?

[JonnyGoldApple]

I've made (as in ordered all the parts for) my first PC build! There is a problem, however: I didn't check PC part picker beforehand with all the components, and it turns out that my PSU doesn't have the additional 4 pin ATX connector for my motherboard. I checked to see if anything had the connector I needed, but the only one that fit the filter was the one in there right now: https://pcpartpicker.com/list/rWdkjp. While I'm assuming that it does indeed work, It's a little expensive and it doesn't look all that great. The one I had before wasn't on the list, so I used what looked to be an rgb variant that had all the same specs. This is the one I bought though: https://www.thermaltakeusa.com/toughpower-gf1-650w-tt-premium-edition.html. Does anyone know of a PSU what would be more fitting? I'd like it to be under $100 and (obviously) compatible with the build, so if you have any ideas feel free to give a suggestion!

Before one year when i set up my PC, i had the same issue with the 4 pin CPU connector and everybody was saying that it is not needed and its only for extreme OC LN.

Since that year i have seen a bunch of threads referring to this 4 PIN and all saying it is not needed.

My motherboard died a weak ago and the local technician said that there is a big percentage cause of that 4 pin missing.

I got a new mobo (RMA) and i bought a PSU that had that extra CPU 4 pin connector....  

EDIT: The best PSU in the market are the Seasonic half of Corsair PSU's are from Seasonic 

And they make CPU's for many other brands

If it was needed, more psu manufacturers would make it a standard. It's not needed

Of course if you buy a PSU for a desk PC you don't need it, but all new CPU's for gaming have this extra 4 pin CPU connector

You have a processor that consumes up to 120-150 watts.

The 8 pin EPS connector is good for around 300 watts, so through the life of your system and motherboard, the connector is well below its maximum advertised and guaranteed capabilities.

The 4 pin ATX connector simply adds more wires between the power supply and that circuit which powers the circuit, so instead of having the 300-350 watts top limit, you now have around 500 watts top limit.

 

You don't need to connect the 4 pin ATX connector. It won't hurt it if you connect it, but it will not do any good either. The processor simply doesn't consume enough power to matter.

 

Rather than focusing on power supplies that have both EPS and 4pin ATX connector, focus on a quality one from a brand name, known manufacturer.

You're looking at around 300 watts maximum power consumption, for the whole system, maybe even less, so even a 500w power supply would be more than enough.

 

I'd suggest going with something like this :

Amazon.com: Corsair RMX Series (2018), RM550x, 550 Watt, 80+ Gold Certified, Fully Modular Power Supply: Computers & Accessories

The processors don't need it.

Even the Ryzen 3950x processor only consumes up to around 200 watts.

Anandtech measured 147 watts when benchmarking and abusing all the cores: https://www.anandtech.com/show/15043/the-amd-ryzen-9-3950x-review-16-cores-on-7nm-with-pcie-40/2

Toms Hardware measured 145 watt peaks : https://www.tomshardware.com/reviews/amd-ryzen-9-3950x-review/2

Guru3d measured 220 watts for the whole system (mb+cpu+ram and idle video card) : https://www.guru3d.com/articles-pages/amd-ryzen-9-3950x-review,7.html

 

If you overclock a 3950x and use a good liquid cooler, you may get close to 200 watts. That's still way below the 300+ watts limit of the 8 pin connector.

 

The extra 4 pin connector is there for those people that use liquid nitrogen and cool the processor below freezing point and pump lots of power into the processor, getting very close to that 300 watts maximum limit of the connector.

At such moments, using an extra power connector makes sense, because instead of sending 300 watts to the processor through 4 pairs of wires (around 6A of current per pair), you're now sending 300 watts through 6 pairs of wires (only 4.2A of current through each pair) so now the cables and the connectors will heat less.

Your technician was either a moron, or figured out you're kind of a noob and simply decided to skip the actual investigation and just placate you and say it was your fault because you didn't use that connector.

 

If it worked for months I'm 95% sure it wasn't the lack of connector responsible for your mb failure.

 

Also, Seasonic is a very good manufacturer, but it's just one of a handful of very good manufacturers.

 

Last but not least, your information is outdated. Few series from Corsair are actually made by Seasonic these days.

You can look at this page and count how many that are not discontinued are actually made by Seasonic : http://www.realhardtechx.com/index_archivos/Page447.htm

There's a new vers for $100, and a renewed vers for $40. What would be the cons of taking up that offer? I could use the extra budget room for a better cpu cooler than the stock wraith spire (which is what I'm going with currently, but the part picker doesn't have that). I have a feeling, though, that there's a catch to the renewal...
