Obviously Corsair works with CWT closely to produce units that will be most ideal. I'm curious how closely they work with them.

I actually don't have any idea about how they work out that stuff. You may be right, and if you are, and Corsair really does work closely with CWT to produce a final product they feel good about, then they need to be ashamed of themselves for producing something like the CX750 and a "gold" rated CS. Who cares if it's gold rated if it's not going to last a year.
 
EVGA still has their GL and GX PSUs coming up, I wonder when they will be released precisely. The GL is just the G2 with a modular panel that lights up, like Superflower natively has on the Leadex Gold. The GX is more compact, smaller depth (think Silverstone or Cooler Master V Series). The GX is based on an updated Leadex platform apparently. I just hope EVGA doesn't try to phase out the G2s and end production with more expensive options. Obviously the GL will be more money since it will glow up on the modular panel. And the GX, it'll probably be similar in price.

What concerns me is that the GX will probably not be as high of quality. Compact dimensions always means that performance takes a hit. It also means that more likely the PSU is less expensive to produce, being less long and all. Of course it depends on other factors, but in general smaller stuff costs less money. EVGA may be planning to increase its profit margins by selling "new" G2 units under the GX name which will cost less to manufacture and more to buy.

It wouldn't be a good move on their part from a business perspective. EVGA PSUs have a lot of bias toward them, and so many people just trust the EVGA name. They may be planning to use that to their advantage which would put us consumers (us, that is, who actually look into PSUs) at a disadvantage. But for the majority of people (those who don't give diddly squat about PSUs) will probably buy them nonetheless.
 


I wouldn't be ashamed. The CX lineup was probably the most successful thing Corsair has ever done for business. They're probably throwing parties every night! :lol:
 
EVGA SERIOUSLY likes to flood the market with as many psus as possible. I guess it's not a bad thing, but geez.

I have only good things to say about EVGA's customer support, and kudos to them for extending the warranty on their barely mediocre NEX units.

I still wish they were more consistent in their products. We shouldn't have to say that half of their lineup is great, but half is not really recommended... especially when a lot of them share the same exact target audience.

Haha I believe that, but that just makes them evil. There's no doubting the success of the CX lineup but that does not make them GOOD by any means.
 


But it also does not make them bad just because we know that they should not be used for higher power designs. I never recommended a CX series for a gaming or workstation build where I knew the PSU would be under heavy load. I recommended the TX (at the time) line for that.

The CX line was good for replacing the cheap junk that most OEMs put in their consumer grade PCs and nothing more which is the majority of what I installed them into.
 
Umm turkey, when it comes to electronics, smaller is always more expensive, not cheaper. Take a standard 5% 1k resistor. If you cut it in size by half, you'll have to seriously play with its chemical composition to get the same resistance at the same variance. Ceramic just won't cut it anymore. So now you get into special order parts etc. And the size of some components can't really change much like rectifiers, mosfets, heatsinks etc which just makes the price of real estate on the main/daughter boards very expensive, so sumptin gotta give somewhere and it's usually those extra little circuits that do such a wonderful job of cleaning up the rails outputs. So understanding silverstone's lackluster performance and outrageous pricing is easy. To me it's what makes the new CM's such a game changer in the SFF market. But thats mho.
 
The G2 warranty is ten years as long as you register it within thirty days of purchase. Othewise, it's five years. My G2 750 has a ten year warranty because I registered it right away.

I've had it going on two years now, running a full time, full 1Ghz beyond stock clock overclock, on both machines it's been installed in, and for the majority of that time with an overclocked R9 290x, and have not had a single issue, episode or problem with it or it's hold up time of any kind. And I've had several lightning related power outages here during those two years as well as a pretty fair surge on one occasion that destroyed one of the breakers in the main box. So while it's only a sample of one in my case, this sample has shown itself to be exemplary.

Edit: Looking at the warranty specifications on the EVGA website, it seems the warranty is now ten years, period, whether you register it immediately or not I guess.

The ideal is somewhere in the middle - go bigger, you need more materials. Go smaller, you need better precision. For a 1k resistor, I think the point would be somewhere around 0805 or 1206 SMD.

This point moves over time, generally in the direction of smaller. Cramming a whole PSU into an AT/ATX PSU case could've been kind of hard twenty years ago. Dead easy now - it's SFX that's kind of hard.

Also, you're dead wrong on MOSFETs, diodes etc. not getting smaller. They used to be massive tin cans bolted to heatsinks. Then TO-220 bolted to heatsinks. Now they're SMD D2-PAK with a thermal pad to the case, running at an order of magnitude or two higher switch frequency, so the transformer needs far less core material. Likewise, APFC takes up no space compared to a big choke, and all that efficiency means you can get away with tiny heatsinks.

Board space costs $$$, remember.
 


Not specific enough. It depends on the exact model number. The TR2 line varies from some of the worst power supplies sold under a major brand name all the way up to pretty good.
 
They are both OEMs. Both companies have the same ability to build a top line, best of show type psu of high quality. The difference between them is that SuperFlower quite often does and HEC usually doesn't.
 
What tier would the EVGA 750 BQ be on? Tier 2? Because, I notice that the 750 BQ has three hybrid 8 pin slots and three 6 pin slots. Also runs 10c cooler than the B2 and is $5 cheaper. While the 750 B2 only has four 8 pin slots and runs hotter at 10c more.
Sorry for the extra details, I'm building my first pc with a Evga gtx 1080 FTW and planning on adding another identical gpu in the future

Will you be running multiple 4K monitors? If no, adding another 1080 will be waste.

Also i don't get running 10c cooler. If you are talking about rated temperature, higher is better.

Buy a decent psu. The Rosewill Quark 550w was $60 yesterday. Check if the deal remains.
 


Yes I will be using multiple monitors/tv. 1 65in Sony 4k tv and 1 22in Dell 1200p monitor.

550 watts will not be enough. My 1 gpu by itself needs 215 watts. My whole build is at 422 watts and another gpu for sli would put me at 637 watts. I think I will stick with the EVGA 750 B2. Thanks for the help. I learn something new everyday,
