Which PSU would be better?

[Bilal Sohail]

Hey guys, 

I recently upgraded my system to an i5 8600k @4.7Ghz and finally bought a MSI gaming X 1070ti 8GB. 

There are 2 PSUs which belong to the tier 2 list that i can choose from:

1) FSP Hydro G HG750 750W 80 PLUS GOLD Certified Full Modular Power Supply  - $106 - USD

2) Thermaltake Toughpower Grand RGB 750W Gold Fully Modular - $99 USD

 

Even though i like the RGB goodness from the thermaltake one but i'd rather have a PSU with better surge protection and more high quality parts used inside the PSU. 
Does anyone have a better idea which is more good in terms of overall quality?

They're in the same tier so I'm assuming negligible difference. Go with what looks better with your system.

Why are you looking at 750W PSUs for a ~250W system? Get a higher end 450-550W PSU instead.

You might not always have a 250W system.

You  might want it to run in the most efficient zone of the output

You might want it to run cool - and quiet.

You might want it to keep it for many years, best not to run it balls out then...

And even with a 450 watt he'll still have plenty of power leftover.

And it gets more efficient the closer the power use is to the power rating. So a lower watt PSU would be better.

If you get a quality PSU this won't be an issue.

GPUs are getting more and more efficient, and SLI/ Crossfire are slowly fading away. Really no reason to overshoot like that.

Let's say they get an RTX 2070, GTX 1080 or RTX 2080. 450W is still plenty. Let's say they get a GTX 1080 Ti, RTX 2080 Ti, Vega or SLT GTX 1070s. 550W is plenty. 

Assuming they are overclocking. 

 

You do realise the difference in efficiency is negligible in modern PSUs? Oh no, it's 89,5% efficient instead of 90,0%. Disaster! 

 

If they want a quiet PSU, they should get a quiet PSU. Not a high wattage one. Which one do you think is quieter at 250W? A G3 1000W, or a Whisper M 450W?

The G3 runs its fan at 1600RPM. The Whisper M runs its fan at 470RPM.

Running a 450W PSU at 250W is not running it balls out, Just FYI. And do you know what continuous means? It means full load, 24/7 at the max rated temperature, at the full length of the warranty.  Which is 7-12 years for high end PSUs.

lol, short term thinking.  An 80+ Gold PSU will last 6 -10 years. The improvements in efficiency have been great for a long time, but that period is over. GPUs and CPUs will see increases in power usage for the foreseeable future. Don't believe me? check out the 9900K and the 2080ti.

Yeah - my PSU has never turned it's fan on - that's quieter.

 

 

 

Bigger PSUs can always output less, smaller ones cannot output more.

So you have a quiet AX860i. Is it because

1. It's a quiet PSU
2. It's a high wattage PSU

?

(Spoiler: it's not because it's a high wattage PSU)

 

Also, in many cases, the lower wattage PSU runs its fan at a lower RPM than the higher wattage versions, at the exact same load.

And the higher wattage ones also cost more, and if they don't have multi rail, they can cause more damage. And as mentioned, they are often louder. 

Paying more, and running the risk of more damage, and getting a louder PSU because...? Yeah, that doesn't work. 

 

Powering a 250W system with a higher end 450-550W makes more sense than powering it with a lower end 750-850W.

Umm - yes it is. It's running at a fraction of it's capacity - it's exactly why the fan never turns on...

 

I am sooo sorry my opinion doesn't match yours. Perhaps I should just change my mind despite copious evidence to the contrary.  /S

My version of the overclocked 1070ti takes around 304w while gaming as per what i saw from the benchmark videos on YouTube.

 

The thing is that i'm swapping it for my GTX 1050 gigabyte (1 year used) from a local shop and he only has the above two 80+ gold PSUs.

I planned on getting the 650w one for future proofing it a bit but that one got sold out so these are my only options. 

my current one is a Cooler Master GX series 550w 80+ bronze which is around 6 years old now and i don't want to risk my new parts on it. The PSU is absolutely fine though, so i plan on using this on my old pc where is was previously used in. (i5 3570k).

 

So, from the above 2 i am leaning towards the thermaltake one as it's more recent compared to the FSP Hydro G and has high end capacitors. Didn't find many reviews on either of the PSUs on YouTube.

 

During a storm in my area, my electricity fluctuates and i'd want a PSU that can handle that sort of thing. 2 of my previous cards have already been fried because of that.

I'll be getting a surge protector and a stabilizer soon as well though, hopefully that will solve my issue.

No, it's because it's a quiet PSU. I've already mentioned the G3. Despite running at a fraction of its capacity, it manages to be louder than yours. 

Changing your "opinion" based on opposing facts would mean you're rational.

In your entire area, they only have two PSU models available?

Don't bother looking for PSU reviews on YouTube. If you want actual reviews, read them. 

Aris has reviews on both, on Techpowerup and Tomshardware. 

The Grand RGB has a bit better regulation.

The Hydro G is quieter until ~375W. 

The Grand RGB has lower ripple on the 3,3V and 5Vsb rails. The 12V and 5V ripple is pretty much the same for both. 

The Hydro G is better in terms of transient response on the 3,3V rail. 

The Grand RGB has a bit longer hold up time (both are within spec).

Thanks mate, i'll give these a read.

The others don't accept used parts that's why and i don't have any extra money left for that. I have to get another HDD for my previous pc to actually be able to run it. 

for me sound isn't really any issue, i just want to focus on the quality. If you were to choose between these two, which one would it be?

Both are OKIsh, throw a coin.

But as people say, its not needed and you might waste money on it...

1. A 500-600W System is around 500€ for each CPU and GPU, 300€ for the Board or so. w/o Memory. So no, probably not.
2. wich is between ~30-70% Load, not that bullshit 50% thing that is because of 80plus
3. That's just horseshit, a lie and violates the laws of thermodynamics. You can think how one PSU can be cooler, when its about the same efficiency, has the same heatsinks and is loaded the same (ie 550W). Yeah, Physics's a bitch...
4. ...wich never made too much sense as there were always things changing so there was never a point in time where it would make sense to use a 10 year old PSU with new hardware. NEVER!

No, Smart thinking.

You get what you need and makes the most sense for you.

Not what eventually, hypothetically could make sense.

 

You don't buy 255mm tyres with V-Rating for your Renault Twingo because you could eventually sell it and get a Porsche.

If you're wrong, you pay him for a new PSU?
What if there is something that makes today's PSU incompatible with upcoming hardware?
What if they get rid of ATX allthogether?!

Just a reminder:
the AT "Standard" didn't even last 10 years!

And with a new Standard with 5A on +5V and no negative Rails, no 3,3V, only 12V for the Motherboard my guess would be something up to 15€ less for a PSU.

Oh, now you're a fortune teller, are you?

The 9900K is officially still a 95W TDP.

And the last 220W TDP Consumer CPU wasn't too sucessful.

And there is a point where you can't cool the shit no more either. So there's a limit to the Power Consumption...

Yeah, because you have like a 100W System or so...

That's not an argument or proof of anything.

[WihGlah]

Lol, take a look at my sig . 100W - LMAO

 

Pulls 325w on CPU test and 500W during TimeSpy Extreme + Prime95 AVX at my 24/7 overclock. (my standard stability check)

 

When I pump it up to 5.3GHz it pops over 550W.

 

And the PSU fan STILL DOESN'T COME ON. 

 

Oh - and my CPU is a golden sample - there are folks pushing +0.2v more than me.

 

 

Just enough - isn't enough.
