It might be OK, I bought an Intel board a while back which had a CPU power phase transistor that had burned. The CPU and RAM in it were just fine.

Okay yeah i just checked the case comes with its own "nipple?" stands

Hard lessons for you:
-Three things you NEVER buy used; SSDs, Hard drives and PSU.
-The rest, you either
       Test on site
       Buy from eBay with money back guarantee

Not sure how you made that huge ass leap from what he said.. he basically just said your friend is shit.  That's all.
 
RMA the motherboard, get a replacement.  Buy a new PSU from the Tier List.
 
Try to assemble PC again.
 
Then let us know what happens.

It's possible,considering the age of it i wouldn't trust it at all.
RMA The board and the PSU,and hope that they will accept the motherboard.

It’s a pretty solid unit

Alright I see what that conversation was about, I mean, safe than sorry is a good motto to live by.
 
I will most likely be going with the kit anyways to avoid any problems 
 
 

It's the best practice to buy sets of matched sticks if planning to run dual channel, especially with higher performance memory. It's not always necessary but doing so increases the chances of having a smoother time getting it all running and having both sticks operate the same speeds and timings when their memory IC's have come from the same wafer and are all of the same quality.
 
Will it still work if you buy them separately, probably. However if the price is the same then why introduce an added variable for failure?

You seem to be confused about what I'm saying. They can obviously have all of the same specifications, however if the little green thing that is the RAM inside that heat spreader is from two separate RAM manufacturers (again, happens frequently), the BIOS in your PC may or may not recognize them as dual channel, and thus you've got two competing single channel sticks. (And this does happen.)
If you order two separate sticks off of Amazon or Newegg, there is plenty of likelihood that they are not off of the same production batch. They are individual units in shipping warehouses. It's not Amazon's job to ensure both pieces sold are from the exact same batch, and couldn't anyway.
 
In this case, per your suggestion, the OP would be paying more for no guarantee it will work... I don't see the argument.

Not necessarily. If overclocking RAM is a desire, then certain spreaders will be better for heat distribution. 
Vulcan is one of the new kids on the block, G. Skill is a trusted veteran. That said I've heard only good things about the Vulcan brand, and their spreaders look pretty cool for low cost. 
I personally like the G.Skill Ripjaws. They might be a few bucks more, but they are great spreaders that look nice, and they are very competitive in the overclocking game, too. (Made of metal, good for even heat dispersal.) That's not to say other options aren't just as good (or even better!)

This is true of the B450 series, and generally speaking at the low end of the price range. 
In fact the cheaper series Gigabyte boards are straight up bad.
 
Gigabyte -again, generally speaking- makes better high end boards.
 

Different manufacturers of PC components. Foxconn makes a lot of CPU slots and sockets and so does Lotes. Both make AM4 sockets but they're built slightly differently so you can't use Foxconn parts on Lotes or vice versa.

The Tomahawk and Mortar (and Max versions of both) are some of the best B450 boards around. Good component quality, good VRM with heatsinking. I'd say they're on par with most mid range X470 boards from what I've read.
 
So there's a trick to buying AM4 boards I've found that I'll share. It's not uncommon to find them with broken socket tops, that part IS replaceable! As long as the pins are not damaged the socket is fine. Order the correct Lotes of Foxconn socket for about $8 from China and snap the plastic locking cover onto the motherboard. You can score boards for 1/2 off that way.

On the b450 boards they have better vrms that run cooler and allow for higher cpu boosts, core counts and overclocks. However, on the x570 boards for example, the asus and gigabyte ones are better.

I'm not too up to snuff on what's good now. I snipe ebay deals and look around for what's for sale and then research that specific model to see if it's what I want and what I want to pay for it. Recently I bought a BitFenix Whisper M for my HTPC and it seems well reviewed and rated from JonnyGuru.com but it's now discontinued and subsequent models seem to be lesser. My latest purchase was a 1000W RM1000X Corsair for $100 shipped but that would be serious overkill. If the other PSU in the RMX series are as good at the 1000W unit then one of those may be good buy if you can get it at the right price. Check out the PSU tier list here!

Msi make better b450 boards. For psu, a corsair cx, tx or rm series, bitfenix gold or bequiet gold

Me too for my TR2 750W, googled it to see if it was ok to reuse and found out it is not ok to even use in the first place!

The only thing that you could probably keep from it is storage, case, and your GPU, but with all of those there are much better options new.
 
 
For now, I would throw in an SSD and save some more money to get a completely new system.

The 980 isn't a bad card still, just a bit power hungry for what it does but still a solid card.

Heard to break it to you, but everything but the power supply and case may be trash.
And depending on what parts you decide to go with, those parts may also need to be update.
As for the 980, the $200 1660 outperforms it, so when you get to making the new pc, it might not be up to snuff for the games you want to play.
 
For now just increase ram and do a clean install of windows on an ssd and you should get another year or 2 on this machine.

That, being a Thermaltake TR2 PSU I assume, is a terrible PSU. The 750W version blew up on the test bench TWICE when reviewed ages ago when it was new, at only around 500W load and had HORRIBLE voltage ripple on all the rails under load up until it popped. It's an avoid at all costs line of power supply units, please get something else before it damages a new PC build.
