Power Supply issues with i7 3770 + GTX 1060 6GB

[Zehownz]

Hey guys, thank you for your attention. So, I've decided that I wanted to build a gaming PC. Since I'm on Senior year of Aeronautical Engineering (BTW, I live in Brazil) and I'm not sure of what is going to happen in the future, I decided that I wanted to build a PC with a graphics card that could handle 1080p very nicely + a processor that could handle the eventual ANSYS/SolidWorks/MatLab/Catia.

So I went with a Core i7 3770 (non-k, because I already had a Asus P8H61-M LX2 R2.0 motherboard in my house -for free-);
A Galax GTX 1060 6GB OC (I haven't Overclocked it);
16GB of Corsair DDR3 Value Select RAM (@1600MHz);
A 500Gb HDD (SSD on the way);
AND for Power Supply I used the Corsair and Outervision PSU Calculators, and the highest number I got was 335W (Load). Both programs recommended a 380W PSU (non existent here, 400W being the closest). I decided that I wanted to be a little more safe and got a 430W Bronze certification PSU from a local brand called PCYES. The exact model is PCYES Electro 430W.

>Here is a video from a reputable local Company that made me trust the brand, showing that the PSU actually offers 430W to the PC with 85% effiency, drawing 505W from the wall on full load: https://www.youtube.com/watch?v=mXM3op-nsoc

Ever since the PC have been completed, I've been gaming and getting these annoying CTD on different games like Mafia III and The Witcher 3. Most of the times there aren't even error messages, the games just close.

I'm not sure if that is because of some power starvation coming from the PSU or if that is because of software issues. I did noticed though, that it happens mostly when the games are saving or loading a new cut scene or stuff like that.
I'd like some help figuring out what that could be.
Is that a software problem or is it my PSU?
Would updating the BIOS fix it?
Can someone help me, please?
Again, I appreciate your attention and BTW, sorry for my bad English.

No, side fan is of no benefit in place of a top fan because a side fan offers no benefit as an exhaust, only as an intake. Having only one exhaust fan, which is in the rear, is not sufficient. One rear and one top exhaust fans is probably MORE important than any other fans on the whole machine EXCEPT for the CPU cooler.

It doesn't matter how much cool air you get in if you can't get the hot air OUT, because then that cool air just turns to hot air before it can even be used by the GPU or CPU coolers AND you end up with a whole lot of very dense, positively pressurized hot air instead of a constant exchange of hot air for cool air. You either want the pressure differential to be balanced, with two intake and two exhaust

(Preferably of the same size, but since the majority of cases only have a 120mm rear exhaust, then sometimes you have to live with a slight positive pressure differential if you also have a top 140 and two front 140's) OR have a negative pressure differential with more exhaust fans than intake fans. You never want a significant positive pressure differential because it is less efficient, does not cool as well and put unnecessary strain on the intake fans. Positive pressure is only desirable, in some cases, if you have severe dust problems and no filtration. Positive pressure helps somewhat to minimize dust entering the case but at the cost of cooling performance.

I always avoid it and aim for balanced or negative pressure differentials. Positive pressure setups can see up to a 5-7°C worse cooling potential than a balanced or negative pressure system.

So, unless that case is configured to where you can mod the case to accept another fan up top, and that seems like an unnecessary amount of effort if you're going to put out cash for a case, I'd probably skip it. It would be worth waiting to find a suitable model.

How much do you think you could squeeze out for a case and some fans? Do you have a link to any online hardware vendors in Brazil that are trustworthy or preferred, or is there an Ebay link to the regional version you can use?


Also, yes, side intake fans CAN help to keep the GPU card cool, but if the cooling system is configured in an acceptable method to begin with, side fans are generally unnecessary PLUS if you have or get a decent sized CPU cooler at some point, there will probably be interference issues.

First I would like to start by apologizing for taking so long to answer, however, the time difference between where we are is huge. I replied at 2:00am today and it showed me like it was 6:00pm of the previous day on the website (if I saw it right, I was kind of tired). Haha

I understand, it was just a moment where I thought I had found a decent case.

Wow! I actually didn't know that. I watched a JayzTwoCents video and he mentioned you always wanted a slight positive pressure setup, but he didn't mentioned you'd get worst cooling by that. I personally prefer to extend the lifespan of my parts and clean the PC more times than the other way around.

At this moment I have R$260,00 to spend on a case + fans.
These are the Websites I normally buy from:
http://www.mercadolivre.com.br (This is the "South American Ebay")
https://www.pichau.com.br/hardware/gabinete

Second and Fourth Links are for cases, Third and Fifth links are for fans. On "Ebay", you can find whatever you want, thought.
The big thing you're gonna see is price. I looked at american websites like Amazon and Newegg, PC parts, cases, fans, or whatever are so cheap in America! Even by converting Dollars to Reals it would still be so much cheaper!
Just as an example, you can get a GTX 1080ti with 740 USD (that's like 2.4k BRL), in the meantime one of those would set you back 4k around here. It's absurd!

For small stuff (like video cards, CPU's, my buddy in Brazil would literally get on a plane, fly to the free trade zone in Belize, spend a night drinking at a nice hotel, fly home, pay import duty on the card and still be ahead money. That was ten years ago, but I see pricing hasn't change.

Absolutely! It's a fu#@*%& joke.
The Case that I particularly like the most is the Deepcool Genome (I played a lot of Resident Evil as a Kid). One of those on Newegg costs 190 USD. One of those here: 1.3k BRL!!!

I'll take a look when I get a chance. In the meantime, as far as fans go, the Noctua models you want to look at really are the NF-A14 for 140mm models and the NF-F12 for 120mm models. The NF-A15's are good fans too, but they have an oddball frame width, being 140x150mm but with 120mm mounting hole pattern, so it won't work in every location but will work for most any location with 120mm mounting holes that supports 140mm fans in that location.

The Redux line of fans are still good fans, as compared to some other fan brands out there, but their specs AND more importantly, their sound profiles, pale in comparison to those two fans. Also, any of the Chromax.black.swap versions of those two fans are good too, being exactly the same but just black in color. You might also be interested in any of the Noctua PPC industrial fan models, as those are fans with exceptionally good performance, even the 24v models which WILL run in 12v systems and will do so with incredibly low sound levels and will actually run perfectly fine, unlike any other fans out there, all the way down as low as 125 RPM.

As far as cases go, I know you are pretty limited in your selection there, but I tend to look at Fractal design, NZXT, Corsair, Phanteks, Be Quiet, BitFenix (A few models. They've got some real poopers too), In Win, Silverstone (Again, some good models, some WTF models), Thermaltake (Probably 50/50 good vs WTF), Enermax (Same), Cooler master (Same) and Rosewill (Also some good some trash) as my go to manufacturers depending on what is required, what is available on a regional basis and what kind of budget I have to work with.

Pretty much all of those manufacturers, if the case has all the features you are looking for such as number of fan locations, fan size support, removeable drive cages, water cooling support, cable management room in the backside, etc., are generally known for decent quality cases. As noted in the parenthesis above, and even for those that don't show notations, most of them have both very good and "why in God's name would they have ever put their name on this case" models, so you really have to be aware of which one you are getting and also it's usually a good idea to take a look at professional reviews (From a reputable review site) before making a decision on any specific case.

Since necessity is the mother of invention, I am always in favor of taking a case that has the makings of a good product but lacks something you need, like enough fan locations, and modifying it to meet your needs if you have the necessary tools and skills to do so reliably well. For example, I took a Cooler Master storm enforcer that did not have particularly good intake or exhaust fan support, and modified it so that it could accept a rear 140mm fan and two front 140mm fans in addition to the top fan support it already had for a 200mm fan.

That's just one example, but here's a link to that modification process in case it might give you some ideas about what be made to work for you.
