All we can do is give advice.
Maybe some visitors think everyone here with lots of posts or rep is an elitist pro or know-it-all. Maybe some people don't even want to ask for fear of being talked down to.
We're just people.
But let me clear up something about picking PSUs. Something important.
A power supply is just as important as a CPU or GPU. The wattage is just a number, the quality is what matters. Good PSUs supply clean and reliable power to the entire system. Is that all? Yes, it affects everything every second the computer is on.
The Corsair CV650 isn't even so awful on it's own, but it's been sitting unsold for a few years now, and it's warranty period is only 3 years. It's much worse than it appears.
Even brand new, it wasn't good or reliable. The best thing that could be said about it is that it wasn't dangerous. But now that it's effectively out of warranty, it is a bad PSU.
The reason "experts" always urge buying a quality PSU is because it's
very stupid to buy cheap, and almost impossible to overspend!
That is different from other components. Overspending on other things is still stupid but harmless. Buying a bad PSU is
NOT harmless!
That's why they should be avoided! Not because of some arcane enthusiast rule.
It doesn't go against rules of PC building; It's not form or benchmarks; It's not because "experts" say so, and you gotta buy one to be cool. No
It's because a bad one is bad enough to fry a computer. When you're broke, you don't want that to happen.
Even if the worst doesn't happen, a lousy PSU will very likely not be able to deliver it's stated watts. That can lead to games crashing or weird Windows behavior. Motherboards or components could get damaged; a bad PSU puts everything at risk! Every second the computer is on.
It can even start a fire if it's dangerous.
And that's what it is.
Dangerous.
Is that all?
And yet...
People will risk it. So if you must. If you have no alternative at all and you must choose between terrible PSUs.
Don't!
Slap yourself.
Save money. Be patient. Buy a good unit.
When someone buys any new part for their PC, they are happy and excited to have a nice new box in their hands. It's something they expect to be a lot of fun. There's an element of giddy joy in buying new stuff!
So when you buy your cheap and unreliable PSU, just remember what you hold in your hands.
Crap.
That you went and paid money for.
So, don't.
Save money. Be patient. Buy a good unit. It will work well for many years. Everyone's a winner.
