Recently = my upgrade cycle, and I've been an Nvidia user. I wasn't about to spend Titan money for 6GB when they came out. I got the 970 I believe spring of '15. Remember also I then spent a year in New Zealand with the desktop in storage. Nvidia cards didn't generally have more than 2GB until the 10 series except for a few cases.

 

Wait, what?

I remember buying a 560 that had 2gb in like 2011.

 

That's when I bought my 560 as well. More than 2GB is different than has 2GB. Nvidia jumped up to 2GB and then stalled there for the most part until the 10 series. There were a few versions that had 4GB but generally they had 2GB.

 

680, 770 classified, 780, 780ti, 960, 970, 980 and ti variants.
After the 560ti almost all 256 bit cards had MORE than 2gb memory and when they didn't they made up for it in clock speed and still had 2gb of gddr5...

I don't consider 128 Bit cards big gaming cards. And even after watching a bunch of 1060 3gb vs 6gb comparisons it really only makes a difference in certain games. PUBG being one, but even then 3gb is more than enough.

I'm not trying to argue or prove anything, I'm just saying that the cards were out there and we all had the options for more than 2gb at less than titan prices.

 

You people and your 144hz trying to make me jelly.

 

Surprisingly Ghost Recon wanted 4 GB of vram at 1920x1080 with mostly maxed settings, but only 4.4GB at 5760x1080. That really surprised me.

I really like my 21x9 1440p monitor. I put my old 24" 1920x1200 monitor next to it off the right side. Physically the screen heights are a decent match, I have almost the same horizontal pixel count for my desktop as before, and my vertical pixel count is much improved.

 

Electrical gurus mind helping for a sec?
I have an outlet for air conditioning unit that measures 245 volts.


Can i use it as power to my psu?

Also theres no switch on this PSU to go from 120 to 240. is it automatic or whats the deal with that?

This is the receptacle for the ac plug.

 

If the label on the side of the PSU says it can support 240V, it can support 240V.
Most high quality >300W PSUs these days have Active PFC and can deal with a wide input voltage range automatically (usually something like 80VAC-240VAC).

 

Power supply will support 240v. You just need to use the proper plug/cord.

All of my mining machines run on 240v, you can gain an extra few percent of efficiency from the PSU too.

 

120/240 switches went away when linear power supplies gave way to switching-supply designs in the late 90s / early 00s.

I know, that sounds confusing, how only switching supplies don't have a switch. The "switching" refers to the fact that, internally, they rectify the incoming power to high-voltage DC, and use solid-state devices (MOSFETs or similar) to PWM it to the appropriate level. (The PWM stage is the "switching" part.) This is a highly simplified explanation, but the advantages are higher efficiency and less cost to manufacture.

Linear power supplies used a big, heavy transformer to get the incoming voltage down to something close to the desired output voltage, and then linear (analog) regulators to finish it. The input-voltage switch selected between two primary taps on the transformer to select the appropriate conversion ratio.


Is the PC the only thing you're planning to plug into this outlet? Just kinda curious why you want to use the aircon outlet.

 

so I usually skim this thread because who cares, but then I went and did something for fun.

And there it is. Sorry gamers. I promise I'll make you a good deal on them in a year or two.

Bear in mind that this is a hobby fun experiment and my primary goal is to break even some day.

 

Move the fans to the back, Pushing air is more effective than trying to pull it.

This is one of my older setups. I'm up to 6 rigs now...

 

Moving the fans to the back will also prevent me from getting my bellybutton region shaved every time I reach around the rig. Good call.

Also those Cerberus cards (on the right) have pretty uninspired cooling. The Founders (on left) use a blower and send hot air straight out the mounting bracket vents. My wife could dry her hair on it. The hot air from the Cerberus just goes out randomly through all sides. Temps are all pretty reasonable though: 49-63 C at the hairy edge of overclocking.

 

I really appreciate the explanation. Eases my mind quite a bit.


Mining rig sir. currently have 2 850s hooked up which are blowing my fuses if i was to plug anything else in the entire living room (120 is shared in the room).

So wait, does polarity between the 2 hot pins matter or is it just the ground pin thats the only important one?

 

If your asking this, I would highly suggest buying the cables you need rather than trying to cobble something together...

240v AC has no polarity.

What surge protector are you using? Amazon is being unhelpful since i'm in the US.

 

Yeah, now that I'm about to get some bonus money I've been looking back into building a sim rig.......................yeah no. I'm not paying $1400 for a 1080Ti that was $750 2 months ago. Hopefully Stripe (is it Stripe that just stopped accepting Bitcoins?) will help get these values back down.

So we can watch experiments like yours cost you 2x the electricity vs the value of a Coin.

 

I'm not using anything more advanced than a power strip with a 15a fuse.

 

According to coinbase, I've made/deposited into my bank account $2081 since 1/1/18.
Power cost is $319 since 12/21/17

 

Like I said, I'm hoping it crashes so I can build a sim rig.
