My old PC died partially, how can I make sure that my PSU still works and can be used for a rebuild?

About 11 months ago my old PC started to smell like burnt electronics. I told to myself. what the heck, this PC was cheap anyway, I'll let it die and replace the burnt parts later. Contrary to my beliefs it died about a month ago so it lasted about 10 months more than I expected. I built a new PC, but I want to rebuild the old one anyway to use as a second PC in my room. A few components stopped working, but later I found out that it was just the motherboard and the video card that was faulty cause I tested the rest of the components in my new build. I placed an RMA for the card and I plan to get a new motherboard soon.

I still have my doubts about the PSU. As everybody should know, a faulty PSU can damage everything else in the PC. I was still able to turn on the old PC cause the motherboard was faulty only partially. How can I make sure that the old PSU won't damage the rest of the components again?

Thanks in advance!

If your PSU is fairly old I wouldn't recommend playing with it. PC parts don't like really being moved around but if you want to you can use a Voltmeter to check if your PSU is outputting what it should. There are also some pieces of software that you can use to measure the power input of your various PC components. SpeedFan tells you voltages, fan speeds and temps. It's free so check it out.
My personal recommendation is that you just replace the PSU, they really aren't that expensive and it will save you heartache having to watch your PC die again from an old faulty PSU.

Probably that's what I'll end up doing, get a new PSU. The old PC is about 3 years old. The CPU is a FX-4100. Now that I plan to replace the motherboard, do you think is wise to get a new CPU as well?

These are the 3 components that I'm seriously thinking to get:
01) Intel Xeon E3 1231V3
02) ASRock B85M
03) EVGA 100-W1-500-KR

The following components are old but still working:
04) Kingston Hyper X 1333 Mhz RAM 8 GB
05) Diablotek case
06) Seagate 500 GB HD
07) LG DVD burner
08) Cooler Master Hyper 212 plus
09) WiFi NIC
10) Mouse/keyboard

I'll end up getting i7 performance for about $330 plus the old parts. What do you think?

I wouldn't recommend the Xeon as it focused more on graphic design, rendering and such. Getting an i5 4660 would do the job nicely but I know plenty of people that use the Xeon and without problems. Also if you are interesting in overclocking in the future go for a K series processor like the i7 3770k, all other Intel processors cannot be overclock.
As for the motherboard I would stay away from ASRock as I have had some unpleasant experiences with their products in the past. Go for an Asus or Gigabyte motherboard as they are generally better quality.
The EVGA power supply should be fine and the rest of your components should do nicely, the Ram could do with an upgrade as it is a little slow but should still do well.

First of all, I don't plan to overclock because the improvement I see is not worth the risk. I did for a while and that was what finished to kill my old PC so I won't do it anymore.

Ok, what about the following:
01) Intel Core i5-4690K
02) Gigabyte GA-H97M-D3H

I know that RAM is a little slow, but I paid only $30 for it on sale. I was really looking for 1600 or 1866 mhz RAM but there was any left so I had to settle for that one. The difference in speed is not that perceivable anyway. I'm learning to program Android games so the Xeon will come handy. This one will be my second PC which is intended mostly to watch TWC app and Netflix app in my room and maybe a little gaming.

In my main PC I already have a i7-4790k, Cooler Master Seidon 120V water loop, Gigabyte GA-Z97X Gaming 3 motherboard, 16 GB G Skill 2400 mhz Cas Latency 10 RAM, 250 GB Crucial SSD, GTX 660, EVGA 750 watts PSU and a few more bells and whistles. That should be enough for gaming and program games. What do you think?
