What makes PSU bad?

[thatweirdguy69]

So I'm planning to build a pc (almost tomorrow actually), but as I'm new to this, I asked some people to help me out. They gave me a bill (slightly cheaper than it would cost me to just buy those components alone). Atm I have some time to change components in this bill, I changed i5 for i7, 120gb ssd for 240 one and chose a better graphics card. Besides those parts I was sure about, there is also a thermaltake tr2 600w PSU. It has good ratings on most of my local stores, but that doesn't mean anything to me. There are no reviews online, but on several guides here ( 

 , 

 ) tr2 is said to be crap. What exactly does it mean? Is it worth it to pay 40$ more for something like Corsair CX650M 650W?

What are your other parts?

[HKZeroFive]

Component quality, build quality, voltage regulation, ripple suppression, hold up time, temperature tolerance... there are number of factors that make a power supply unit either good or bad.

 

For the TR2, the biggest complaint about it is the choice of components. They are simply not good, and should not be powering such a high end component as the Intel i7.

Voltage regulation, quality of capacitors and other components, craftsmanship, cooling, hold-up time, ripple suppression and many more things to consider.

Usually when a power supply is considered crap it either has poor voltage control, bad quality parts that are prone to failure, or shoddy construction. (or a combo)

 

In the case of the tr2 the parts inside are garbage and prone to failure, it likely doesn't perform to well either but the main complaint is build quality

If you can spend for an i7 + decent GPU, I don't see why you need to cheap out on PSU, quality PSU gives you the peace of mind.

Keep everything balanced.

There is one version of the TR2 that isn't bad and it's the 80 PLUS Gold rated one. That one is built a lot better and performs very decent. Unless you have that one its best to ditch it.

Nah, it's Thermaltake TR2 S 600W [TRS-0600P-2]. I couldn't really find much about it. In some places it says that this one has an 80+ ordinary. Is this even a thing?

I think I'll swap it for Corsair CX650M.

Thanks everyone, you guys helped me a lot <3

Best to swap it with the CX550M since that has plenty of wattage, costs less, and is the most I would ever suggest paying for a sleeve-bearing fan PSU. Can you afford a Seasonic M12 520W?

Sure, it's around 96$ here. I'm not sure 520 will be enough though. (M12II-520 520W)

[Sovek]

Unless you're running a dual GPU setup, 520W will be PLENTY. I have the SeaSonic M12II on its way right now and has one of the lowest ripples on the market. its a very solid PSU, and modular to boot.

 

I have a Thermaltake Pure Power in my i3 2100 and this PSU is OLD, but still works. That said, one doesnt equate all.

520W with a single GPU is enough.

That's really weird because last time I checked, it said I needed around 502W. Now that I changed some of the components for better ones (i5 6500 for i7 4790k, 120gb ssd for 240gb ssd, rx 480 instead of r9 380) it says I need around 340W. How is that supposed to make sense?

Well, it because the new parts you picked are more energy efficient. Especially the RX480 in your case...

520W is more than you need by a lot.

And this is why we don't use PSU calculators kids! They're all garbage. Your average overclocked GTX 1080 and Core i7 system would never realistically breach 350W.
