This is what happens when you use a bad PSU on your computer
Seriously, what crappy PSU do you have?
Some crappy PSU can last for quite some time, but most of them don't. I used to have one call PowerMan that came with the case. After 5 years that thing is still working. But if your going to do any sort of overclocking, the PSU that came with the case aren't up to the job. You will need to get a better PSU.

Poor ripple filtering causes core voltages to be run higher so that clock cycles do not time out. Worst case scenario is that your ripple is so bad that you get many random BSODs from your CPU cycles missing or artifacts on your screen from your GPU.
Poor regulation could lead to inconsistencies on the rails when under load or higher temperature. For example the PSU might only put out 11v on the 12v rail which makes motherboard and graphics cards run hotter due to I^2R losses and eventually causes failure.
Poor PSUs are made with cheap capacitors which do not last long and are susceptible to heat greater than 40C. All dielectric insulation does eventually wear out but high end PSUs will use quality caps which can last a very long time under higher temperatures.
Poor PSUs also lack protection like overloads, overtemperature, no load, ect.

The possibilities range from nothing to setting your computer on fire. It's possible that a low-end, low-quality PSU will work fine for it's entire rated lifespan, and it's also possible to get a high-end, high-quality PSU that's DOA, or that fails long before the end of its rated lifespan. Having said that, looking at the numbers, reviews, customer feedback, incident reports from fire departments, etc., the smart money is on the quality PSU, even at the higher cost.

is there anyway to test your psu to see how healthy it is and what do you think of these 2? (are they both good?)

Both of them are good, the XFX is better. See this: http://www.tomshardware.com/answers/id-1804779/power-supply-unit-tier-list.html

I'd get an EVGA G2 or P2 instead - the Corsair TX series are good but they use a far outdated Channel Well platform. The EVGA units use the much newer Leadex G2 platform. Read on: http://www.jonnyguru.com/modules.php?name=NDReviews&op=Story&reid=377
