Running an RX580 GPU with Cooler Master MasterWatt Lite 500W 80 Plus PSU

I was advised on another forum that it's not a good enough PSU and could be dangerous and damage my PC ? Is this true ? I have had it like this for a month now with no reboots, blue screens, freezing, lagging etc it all runs perfectly

Thanks

I think I know where the dangerous statement has come from. Jonnyguru has reviewed the 600w version of the Masterwatt lite and pretty much slated it giving it just 5.5/10. He makes the statement "could damage your pc" several times. It's a horrible Enhance built unit with second and third tier capacitors, cheap sleeve bearing fan, stamped steel fan grill and has bare wires apart from the 24 pin and 8 pin which both have cheap sleeving on it. It's only got the basic 80+ white certification as well. Basically cheap and nasty rubbish. I don't get why people are still skimping on the PSU these days when high quality gold rated units are very affordable.

Do you recommend I change it ASAP or can it wait ?

My current PSU has pretty much 100% positive reviews on Google so i dont know who to believe

Lol that happened after 6 minutes though, mines been running months without anything like that, its also a good bit of advertising for corsair. Also that is from 2009

I don't know what to do, some people say my psu is fine and some say its not

Thinking of getting the Corsair Vengeance 750m Silver

That is certainly better than your current PSU. I still wouldn't buy because:

5 Year Warranty, some manufacturers will do 10 years plus PSU warranty.
Not Fully Modular can be a factor.
Only 80+ silver rated, again that factor depends on your PC usage.
Couple of years old design, probably no longer made for Corsair.

750 watt Corsair that will be better than that one for £15-£20 more, could be worth it if you value your PC.

My basket at Overclockers UK:
Total: £108.65 (includes shipping: £8.70)

That one looks good. I'll do some more reading then possibly buy it
 
Don't know what to do, some people are saying i must change immediately and some others say my current Cooler Master MasterWatt Lite is fine ?
 
I'm monitoring my PSU with HWINFO



On the 12v Rail what is acceptable ? It usually sits at 12.024 and the lowest so far during CS GO was 11.808

Software isn't particularly accurate with regards to psu voltages. The only real way to be sure is to use a multimeter. It's within tolerance though. Minimum is 11.400v and max is 12.600v for the +12v rail. I would still be replacing that heap of junk asap.

Well the piece of junk works fine for now lol so i'll stick with it

I'm yet to see anyone say that this PSU has failed them, so it's very unlikely.

I don't overclock and im not a heavy gamer so it will be fine

Wouldn't use such cheap PSU for more than three to four years in enthusiast use PC.

I don't plan on using it for that long, but i've only just purchased my PC 2 months ago and already changed the CPU,GPU and RAM

Some time in the next few months i'll consider the RM750X

I do an hour or two of gaming each day with no overclock so im hardly putting it through its paces
