Hello guys.Soon im going to Bulgaria and i want to buy 2 components:power supply(raidmax800w gold plus) and gpu(rx580 8gb aorus).I want to put my new psu and gpu in computer that im currently using.Now i have question,i want to do minning with this card and i want to know can I mine with my rx580 if i have just 3 gb of ddr3 ram.And will ram make me problem about overclocking my gpu?Thank you all and sorry for my english!Btw im buying other components when ryzen second gen comes out.

1. RAM is not a big concerns for mining, generally.

2. Raidmax have very few *good* PSUs. They have some that are "ok", and others that are outright junk. I'd suggest a better quality PSU - especially if this is for 24/7 use in mining.

3. RAM won't impact overclocking of your GPU - and you'll want to strike a balance between OC'd memory (I think) and undervolting the card for optimal mining performance.

Thank you very much.And yes,i will use it 24/7.Which psu do you recommend me under 100e but with 800w.I picked this one just because it is modular and cards will stand in my gaming rig---RX-800AE-M---.I want to have good look on my PC.And when do i need to turn off my rig...i mean do i need to make pause or not?And will i loose warranty if i mode gpu bios?

Well i will get 2 more card for this year.First i'll buy amd rx 6xx series when it comes out(hope it will be july/august)and vega in late october/early november.I think that 800w gold certificate psu will be enough for that

Not necessarily. You're potentially looking at 3x 200W+ cards, depending on what you opt for.
Add in the balance of your components (CPU, MB, RAM, HDDs etc) and even a good 800W might not be enough necessarily.

For under 100EUR / 195LEV, it doesn't look like you'll get a good quality PSU with enough headroom for "any" 3 GPU setup.

If this comes back in stock:

That'll give you a quality 750W unit....... would require you to be very mindful of the power requirements of the cards you buy though....

800w wont be enough for this 3?I thought it will bcoz i will lower voltage for all of them.I have found people which use rx 580 at 140w and vega 56 at 140w.So lets say ill have 2 rx 580(280 power consumption) and 1 vega56(140 power consumption).3x140=420w and cpu+ram+hdd+fans shouldnt draw more than 150.This is why i thought 800 would be enough

A quality 800W should be (assuming it has the relevant connectors you need), but they don't appear to exist within your budget.

The only "800W Gold" Raidmax unit I can find is this
c443c9666193c015a4e33bffed3cae59


http://www.raidmax.com/power-supplies_rx-800gh.html

While not their worst offering (on spec alone), the max across the dual 12V rails is supposedly 62A ie 744W - and I wouldn't trust it to be capable of anywhere close to that.

I don't know much about that PSU...... it would appear to be a better offering,.....
But it's still Raidmax. Reputations are earned afterall, and Raidmax have earned their rep for junk units.

"Corsair" are a brand. The OEM varies, depending on the product line (and sometimes, model to model).

For a very high level idea of "good" vs "bad", check here:
http://www.tomshardware.com/forum/id-2547993/psu-tier-list.html

It's not an exhaustive list, nor does it have every relevant piece of information.... but it's a starting point.
