Hey all, I might be looking to sell some spare pc parts in the near future.

Is there any software i could use to test them and to use as evidence of it functioning correctly with no issues?

I know of CrystalDiskInfo for storage and Memtest for RAM but what about the likes of CPU, Graphics card, motherboard or power supply?

Thanks in advance

If you show a screenshot of a working device (e.g. device manager or similar) you're already doing more than half the sellers on TM! It also depends on the age and price of the component. If it's newer and more expensive, people want more assurance. If it's a 10 year old component and you're selling for $50 or less then "turns on" should be sufficient testing.

PSU: you need a physical tester to check the voltages. These are quite cheap, I actually have one arriving in the post this week (long story).

GPU: FurMark

CPU: Prime95

Mobo: if everything else works... then you can assume the mobo is probably ok.

How much stuff do you have to sell? Could be interested in a few things. :)

I've had good luck just showing screenshots and publishing fps for a couple of games. Bonus points if said game has built in benchmarks.

I've also been asked to try specific games on a system in the past and people have purchased based on that.

Not quite as applicable if you're just selling parts, but IMO real apps/games are more useful than benchmarks.

PassMark does some reasonable testing

Yea it gets a bit difficult if you want to prove 100% stability. Even PSU you have to test under load to see droop.

Just showing it turns on and runs is more than what most people on Fb or trademe do. The buyer might ask for something if they are worried but a benchmark or two is fine. P95 for cpu/mem and 3dmark/passmark/furmark for gpu or a game benchmark if you have one.

Agreed. Most faults I've found in recent times has been more difficult to surface -- e.g. only appears under certain conditions -- so just turning it on and saying OK is not reliable.

Also some faults can appear but be caused by another component. A while back I had a older machine that seemed to have lots of faulty HDDs but once I replaced the PSU all the HDD issues disappeared. It was an interesting case as the PSU didn't show any obvious sign of issues but on a hunch given the same issues was happening across multiple HDDs I wondered if the PSU was playing up and yep it was.
