Hardware help

[Luca 226]

Can someone tell me / tell which of these is the best option these days ?, I am very grateful!

 

CX430w - corsair

EVGA 430w - evga

[DarkLink64 921]

They are almost equal.

In theory Corsair would be a bit better since it has a Bronze seal, while EVGA has a White seal. This mean, again, in theory, that the Corsair PSU is a bit more efficient in power draw.
So, due to that, EVGA is a little bit cheaper. But they are almost equal.


I got a CX500W and it's running extremely fine.

When come to PC build, PSU is the least you should worry about. Just pick either one of them

[Sheepco 29]

Seeing as they are pretty much equal, pick the cheapest :)

@MIB lol no. Its the most important thing other than motherboard rofl.

Really? Since when? More important than motherboard, you must kidding me.

All you have to do is pick the one that have enough power for your stuff. Might consider some good brand name then the look.

For me I always pick 700W+ which more than enough to run everything I need.

I didnt say more than motherboard lol.

Motherboard > PSU > everything else

[Guest -Linh-]

My PC build is:

CPU > GPU > RAM > SSD > MB > CASE > PSU

 

There is no hard pick for my with PSU coz always broze/silver with modular, 700W+. It is the cheapest of all on my build and can be easy to replace if it die.

But why pick a 700W+ PSU if you, for example, use just up to 300W?

That's just a waste of money on the PSU itself and on the monthly electricity bill.

PSU IS important, you have to check for many stuff when buying one:

Maximum peak power of your PC build with everything running at 100%
Plans for Cross Fire / SLI in future
Overclocking, both GPU/CPU
Efficiency under idle and average load, where the majority of PSU has a very low efficiency (thus drawing more energy than needed). 

 

Also when the PSU is too cheap, or not suited for many stuff plugged on the main board, even when they say have enough power, it may result on your precious motherboard, cpu, gpu, ram, etc, blowing up.

I don't buy cheap psu and I don't worry on electricity bill.

 

PSU 700W doesn't mean it will run at 700W. It only provide the needed power from your components.

 

I rather buy overkill rather than be sorry later.

If you don't know, there is no PSU in the planet that is 100% efficient. The 80 plus seal is to garantee at least 80% of efficiency. The statement that it only provide the needed power is completely wrong.

A 80 plus PSU should, in theory, have 80% of efficiency. That means if your system is currently drawing 100W, it should consume at maximum 120W of your eletricity.

Depending on the quality of the PSU, the efficiency varies greatly based on power draw. This is called the Power Efficiency curve. Something like this:


Each model has it's own characteristic, so it IS a really important stuff to pay attention on a PC build. Just because you like to waste money, it doesn't mean you can spread the wrong information :)

Also, it is a well known fact that high wattage PSU has less eficiency at lower loads, thus, wasting more money, first on the PSU purchase, second on the electricity bill.

WOW thanks for the in dept info. I never spent too much time on this kind of stuff coz I prefer to spend it on other more but this is a good eye opener :).

 

Thanks!

Ah, I feel happy that it helped!

I've been using notebooks since 2008, and recently I bought a Desktop PC,  so I had to study PC Building to ensure how I could purchase stuff that would work correctly without paying too much for unnecessary stuff.

I build PC since long long ago but as always don't care too much on PSU :). Tho your post is helpful but still don't want spend too much time on it :)

If you don't want to get much in depth about PSUs, all you have to do is to estimate the total power draw of your system through this

Now that is life saver

Actually, you can buy a Power Meter that plugs into an outlet and you connect your PC into that. It will give you the exact amount of watts your computer is consuming.

 

I have a miner, and with 5 GPU's running 24/7 I use on average 700W at a time.

RX 480?

470s

You can see the cover of the GPU's in this picture, and the Power Meter on the wall:

I've been trying to buy a RX480 on sale, but it's always being sold out. Damn minners!

They are all back ordered in USA, its impossible to get one direct. Only Amazon/eBay with marked up prices.

[Guest -Linh-]

Same goes with RX580, the miners got them all LOL.

 

I want to get into the miner business but sometime just too much and I don't see the value of it yet to be motivated.

[TrapHouse 102]

They are working on developing GPU's specifically for mining without HDMI ports on them (meaning you cant get any display out of them) since their demand is so high right now. I expect them to be released in summer of 2018, in which I will be upgrading my rig. You'll have to have 1 regular GPU with HDMI output of course to connect to your monitor. Right now I am currently mining ETH solo. It's extremely hard to mine BTC right now because everyone and their mother is doing it. Also, with the fork that just happened on August 1st, more people are getting (or trying) into the mining game in hopes of btc cash exploding.

 

My electric bill is around $155 more per month then what it was before I started mining. I average around .9 ETH per week solo. The ETH price dipped down over the past 10-14 days but I have not sold any of it since I started. I plan to mine for at least 12 months and see what the price is before selling any.

 

It is a good money maker, the problem right now like I said is finding the correct GPU's to mine with.

[Guest -Linh-]

I rather mining in SL =))

Nvidia is developing a crap like that - it will fail hard.

I'm not into mining but from what I know, what makes mining worthwile with AMD GPUs is because:

 

1- It's cheaper than Nvidia
2- It peforms better with raw number crunching
3- It can be sold to budget gamers, when mining with said cards cease to be profitable, to earn a free cash


GPUs without I/O interface and designed only for mining has 0 appeal to minners, because once the card becomes obsolete, it has zero functionality. It will not work for mining anymore, and can't be used to gaming. You can only throw it away at thrash can.

@DarkLink64 @MIB

 

Just got 6 of these bad boys today, along with a 800W CoolMaster Silent Pro Gold and 5 PCI-Express Adapter Cables.

 

 

Edit: Still waiting on the rest of the components to come to set up the second miner.
