Any help would be greatly appreciated
 
Consider your psu purchase like an investment.
A top quality power supply will be good for several generations of builds.

A cheap PSU will be made of substandard components. It will not have safety and overload protections.
The danger is if it fails under load, it can destroy anything it is connected to.
It will deliver advertised power only at room temperatures, not at higher temperatures found when installed in a case.
The wattage will be delivered on the 3 and 5v rails, not on the 12v rails where modern parts
like the CPU and Graphics cards need it. What power is delivered may fluctuate and cause instability
issues that are hard to diagnose.
The fan will need to spin up higher to cool it, making it noisy.
A cheap PSU can become very expensive.

Do not buy one.

I might suggest this seasonic focus 550w unit:

Yes, it will cost twice your apparent budget.

I know Darkbreeze will (might) not agree with me, but from what i know is this one in a more similar price range compared to your choices a better option,

This is why I would not recommend those units.

See JG defending this specific series. You saying it's a shortcoming and him saying it's normal behaviour. Seems for the price a decent enough psu and since the OP only wants to spend a certain amount on that low budget build probably the best option he has.

"Normal behavior" does not necessarily equal "a good thing". I assure you, he does not recommend the use of those unless you don't mind that behavior. Almost everybody I've encountered with one of those units so far has come here asking why it does that and has ended up replacing it with something else because it's too annoying. Personally, I wouldn't want a unit that does that, at all.

I would rather have that the OP would spend more, but looking at the parts used does he look at low budget and i'd rather see him have something at least somewhat decent than him going to make his own choice between those he posted himself.


Recommending something twice the price isn't going to go well here but that's my opinion/guess.

The CX450m isn't twice the price, but I will concede that compared to the units originally posted, the v2 is probably a somewhat better choice, but it's still a unit that has problems. Even aside from the noise, it has issues with high ripple while in burst mode, and high ripple is always bad even if it's only during low loads. Personally, I don't want any unit in my machine with high ripple bombarding my graphics card and motherboard. A lot of premature failures on hardware are due not to manufacturing defects or user error, but capacitor failure from extended exposure to high ripple because of cheap power supplies.

But the other units mentioned are worse, so there is that.
