why i only buy superflower psu. my evga g2 1000w gold has been great to me.

Even if you dont, if your power supply is running at half or less than half of its available power, its going to last that much longer. We are talking years longer. I cant count how many 750w 850w power supplys I went through to figure it out. I had to replace every 2 years because they just went. 1000w? I still have my original corsair 1000w still going in my wife's rig to this day, and I bought it in 2009. Its been running an overclocked core i5 at high voltage with a radeon 290 overclocked for years. Before that, it ran my overclocked 4 GHZ phenom ii 965 BE with crossfired 5870's.

Never get under 1000w if your a gamer, if you do, be prepared to shell out $100 for a new power supply every 2 years. 3 if your lucky. Also when a power supply goes, it takes your motherboard and components with it sometimes. You have been warned. biggrin.gif

So true and I don't understand why so few people get it. I just had to replace my 550 watt (evga gs) because I was getting random reboots on max load with an overclocked 4690k and 1080 (almost 2 years old psu). It sucks because it was recommended to be "more than enough." So I just picked up an 850g3 to go along with the 1080ti, and was in r/buildapc asking if anyone had any experience with it, and no one would give any insights other than "you don't need a new psu, the 550 is fine." Right after I fired it up in regretted not just going with a 1000 watt hahah. I don't understand where this mentality comes from when any psu manufactures specs state the efficiency at different load ratings ....

Edit: this was the first pc I built myself, so relied heavy on forum help when I initially built it (started as a budget build, now its far from that hahah) which is why I got the 550 to start. Now I know the bigger the better with psus- at least it was a lesson learned.

What are the pros/cons of pressing control L in voltage curve and locking?

Love my Corsair AX1500i, a holdover from when I was doing quad SLI. biggrin.gif

It's good for testing a specific bin but you shouldn't game with it.

Boost 3.0 is meant to adjust itself. If it needs more voltage it'll grab more voltage for stability purposes.

Dont lock a bin, let the card adjust itself. It's meant to.

So when I am testing bins should I lock?

I had to lock my bin to 2012 @ 1.000v today to game for some reason. I was trying to stream a TV show on my second monitor while gaming and I don't know if my driver crashed or what but the clocks dropped to the normal 2D clocks. It's like it didn't realize I had a 3D application running for my game. So I had to "lock" it to get it to even set the clocks right.

You just proved my point. 350w-500w under load max is ideal for a 1000w power supply, thats exactly where you want to be at. Half load. Guess how many more years your PSU will last as opposed to one at 75-95% load? ill wager a guess at 5 years, probably more. But hey if you wanna shell out more money on power supplies over the next 5-10 years be my guest. Make sure you keep us updated on when you have to buy a new one every few years. Keep us updated with your collection of dead 750w - 850w PSU's. Make sure to display them as trophy's in your room until one day you figure it out like I did. biggrin.gif

I guess you can't read my sig rig specs but that's on you. Seeing as I have a HX1050 corsair unit. I don't disagree with the efficiency numbers but a quality unit will trump a shaddy oem rebranded unit claiming a set wattage. Thats what will take out an entire system and possibly their home with it. It's blanket statements like yours that people buy 1200+ W units when they are pulling 350-400W max from their wall. But hey I'm done arguing it because this isn't the place.

I've found SuPo 4k is less demanding than stuff like heaven for me. I can pull SuPo benches and then try the same curve in Heaven and it instantly crash.

Some tests ASUS BIOS (Slightly modded) + 10 Ohm resistor mod -

Even though its reporting throttling, i now know what is the cause (PCIe Connector PL, mainly, and one other PL im yet to find)
Next step is to solder on an 8 Pin PCie connector , since there are pin outs and active traces on the GPU board.

No shunt mod, no water, that's pretty good for air I think!
