JonnyGuru talks about power supplies

[64K]

A lexus can get you around the same as a Corolla can. But you don't need a Lexus to get you around. That's the point. A quality Bronze Rated unit is just as good as a Titanium Rated unit in that regards. Most people will do a new build before their PSU has even a chance to die anyway.

 

[Bill_Bright]

How does that make it "Impossible to run on a separate PSU".

How are your going to prevent the card from getting power through the PCIe slot?

its also extremely amusing you "didnt like hearing platinum had better features" (and parts! he stated it requires better caps to provide better efficiency which leads to better ripple and higher operating temp specs etc)

You added "and parts". Not me.

I said, "fancier features" like "braided cables" and "value added" features - like adapter brackets to mount the SFX PSU in a standard ATX case. Why should we have to pay extra for a Platinum or Titanium PSU just to get an included bracket? Why can't they include that bracket in all their SFX PSU instead of forcing buyers to pay $6 extra (plus shipping)?

I don't like marketing gimmicks and that's just a marketing gimmick to get users to pay extra for Platinum or Titanium PSU they don't need.

A lexus can get you around the same as a Corolla can. But you don't need a Lexus to get you around. That's the point.

That is part of it. But the main reason to get a Platinum or Titanium is because they are more efficient - but only by a tiny bit. So my point, which is the same point Johnny Guru was making, is the savings in energy due to the slightly better efficiency does NOT make up for the higher cost of the Platinum over the Gold.

 

[Ferrum Master]

old is not recommended by him for that size psu?..

Well you can... but it would end up damn loud. Well all want almost semi passive modes... so from marketing point not to get burned for making a jet engine like product it must have high efficiency. The other thing for it, high efficiency need less dissipation area for heat sinks, so it can be smaller and lighter. it all goes hand in hand, so the super high efficiency makes sense in really small form factors where airflow also usually lacks.

That's your reasoning for "I only run a second PSU for hard drives and fans", and "It's not possible to use a second PSU for the GFX"?

The PCI-E power is part of the mobo power budget, not the GFX. That question was "is it possible to use a separate supply for the GFX" the answer is yes.
Obviously you will still need to install the GPU in your motherboard...

I DID NOT SAY EITHER ONE OF THOSE THINGS!!!!!!!!!!!!!!!!! Do NOT misquote people. That's not cool and frankly, deceitful and dishonest! If you want to quote someone, use the quote feature. Do NOT change their words to something they NEVER said!

That question was "is it possible to use a separate supply for the GFX"

And that was NOT delshay's question. So again you are being dishonest by misquoting him now!

QUESTION: Has anyone powered their GPU or CPU on a separate PSU from motherboard?

wow i dont think you know how quotes work.. i clearly put the end quote before my parenthesis. And you didnt say anything about how the 750w could not be rated gold because it would be out of spec. so of course they use better parts. its not a marketing gimmick its a fact platinum is a better psu, the added value is so people can help justify the extra cost because their brains all work different. Im not a cheapskate tho when it comes to things that last almost forever. maybe you missed the part when he said "the 750w could not be made if rated gold" ((like ferrum says with out it sounding like a jet engine)) whats that mean to you? because most people are cheap but spend 20$ at mcgarbage everyday yet wont spend 100 on their psu boggles my mind

Cant run gpu on diff psu? lulz
temps at my houses can get to near 50c especially inside my pc case
64k Im 100% sure a lexus has better parts then a corola they dont use exactly same parts and switch the emblem haha

So passionate, you can interpret things many different ways, i think we all know you can run a gpu on a diff psu since its been done 1000x before in the past and there is always a exception to everything. they didnt say "solely through separate psu"

 

[phanbuey]

Since both the GPU and CPU get their power (or at least some of it for some GPUs) through the motherboard, it is not possible to power them with a 2nd PSU. But I have used 2 PSUs before, the second to power drives and fans. But this is not recommended because no two PSUs provide the exact same output voltages and avoiding any "differences in potentials" and differences in grounds, and grounding to Earth ground is essential and challenging.

That's so different from what you're leading people to believe... my apologies for the 'misquote'.

Keep spreading misinformation though, that's totally honest and cool.

 

[Bill_Bright]

I do know how quotes work. I said, you added it.

That's so different from what you're leading people to believe...

I'm not leading anyone to believe anything. The PCIe slot provides up to 75W of power to the card. That is just a fact.

Edit comment: added "up to".

 

[Deleted member 185158]

QUESTION: Has anyone powered their GPU or CPU on a separate PSU from motherboard?

Totally possible.

You can run 2 PSUs one for cpu and one for gpu. It is possible.

The last time I had run 2 PSUs, the secondary switching PSU came with the 24 pin extension cable, both PSUs plugged into the motherboard to be switched on and off at the same time.
That was a pretty long time ago, I don't remember the name of the PSU lol.

That's what I know too but sometimes oddball things happen like the R9 295X2 that had two 8 pin power connectors for 300 watts plus the PCIe slot for 75 watts more but it drew 500 watts in peak gaming and 646 watts running Furmark.

AMD Radeon R9 295X2 8 GB Review

Today, AMD is launching their Radeon R9 295X2, a dual-GPU card based on two fully unlocked, fully clocked Hawaii graphics processors. As a result, the card delivers impressive numbers in 4K and EyeFinity. But with a price of $1500, it is certainly not cheap, no matter how you look at it.

[delshay]

Being an hardware modder you can disconnect the 12v PCI-e on the GFX card & completely run a GFX card isolated on it's own PSU. Not really my cup of tea to do this, as I can't see much of a gain (if any) in going beyond the original 75w limit.

 

[GamerGuy]

HONK, HONK! All three PSU's in my rigs are overkill. I have a Corsair HX1000 Plat, a Seasonic X1250 and an Enermax MAX REVO 1500W. Good vid btw, always trusted JonnyGuru PSU reviews back when he was doing reviews. I had gotten a SilverStone 1000W PSU for my main rig years back after reading his review when he compared it to the PC Power and Coolong 1000W unit, I think these were the only two 1000 watters back then.

Gosh I wish some of you guys where on my overclocking team lol.
I remember that SilverStone 1000w. I went with the Antec 1000w instead. Still going strong, use if for benching

HONK!!

That's what I like, plenty of power.

 

[Bill_Bright]

Without a circuit diagram of the card, I would not count on the card still working if you start cutting circuit traces on the card. You are assuming the 12V from the slot and the 12V from the PSU connector(s) are strapped from the beginning and cutting the power from the slot would not remove required 12V from any of the components on the card. Without seeing a circuit diagram to see how power from all the sources is distributed to all the components on that specific graphics card, I would not recommend cutting through circuit board runs. As that, for sure, would void any warranty too.

but it drew 500 watts in peak gaming and 646 watts running Furmark.

But that is not telling us through which power connection. I said earlier in post #23 "up to 75W through the PCIe slot". I left out the "up to" in later posts. My bad. Sorry if that caused confusion.

always trusted JonnyGuru PSU back when he was doing reviews.

I did too. While I am sure he is doing good for Corsair, and certainly he is doing good for his financial future, if he continued doing reviews, they would always have "the appearance" of being tainted and biased. So he had no choice but to stop doing them. And frankly, I would be surprised if that was not a condition of his employment.

 

[GamerGuy]

Here's the kicker, I still have a spare PSU, and it's a older gen Corsair HX1050.....sitting pretty in its box.

 

[Dinnercore]

This is probably one of THE best videos I've seen yet. Thank you for sharing this.

Loved it.

Honk if your PSU is over-kill!! lol.

I´ll honk three times, two times for both my EVGA 1600W T2s (daily build + secondary build) and the 850W RMi on my OC-bench that is falling asleep during the 2D-benchmarks

EDIT: Judging by the many honks in here, do all TPU-Users have a PSU-hoarding/oversizing problem?

 

[Zach_01]

my fav quote.. "we could only do 750w if it was platinum if we did gold it would run to hot." So it sure sounds like gold is not recommended by him for that size psu?..

By size you mean physical size or wattage size? Because that unit is a special small size (=high density components) so the extra heat of the lesser efficiency, would be adding dificulty to be taken away and out of it from such a small physical size PSU, with smaller heatsinks/fan/internal space...
When a PC draws lets say 500W from a Platinum PSU (93%eff) the total wall draw is 538W (538 - 7% = 500), so the unit has to deal with 38W of heat.
When a PC draws lets say 500W from a --Gold-- PSU (90%eff) the total wall draw is 556W (556 - 10% = 500), so the unit has to deal with 56W of heat.
38W + 47% = 56W

So the Gold one has to dissipate 47% more heat than the Platinum one. When things get too dense and have a stricted space, and lower air flow (smaller fan) 18W (added to 38) can make a difference. You can get the fan to spin to compensate and get louder, or leave the heat behind to start soaking inside... raise the internal's temps and lead to loose more efficiency which will add a little more heat and eventually get louder anyway...

So.. they made a small form factor high power output and quiet PSU and they want it to stay operating like this... (thus the Platinum efficiency)

Dang, I wish my microwave was 1600w... lol.

Watcha benchin'?

 

[Dinnercore]

Actually my microwave is just 800W, so it´s less than my PC-PSUs...

I´m having some fun with Socket 775, 1366 and 1155. Just right now I´m testing my delidded X5650. For the 775 stuff a 350W PSU would be fine, it´s the socket 1366 CPUs that can pull some power but still I did not yet see anything above 350W during CPU benchmarks. (on ambient cooling. LN2/Dice would be a whole different story)

oh thought it was obvious i ment the dimensions but again you can always take things two diff ways or be excited about things diff ways, long post for the exact thing we all knew already. (that the plat has better parts / design haaaaaaa) (not sure why bill bright so excited about yoru post so excited about how gold is the max anyone should get )

Sorry, but I like to be exact to avoid misunderstandings and such type of things... Obviousness and taking things for granted can easily lead to unpleasant conversations. We are here people/PC users from all over the world with alot foreign languages and we simply cant know/remember what is the level of knowlege of every individual in here.

Take a look around how many times fights started upon a simple word... I "hate" that.
So I didnt understand... "obviously" and eventually the point of your comment to the "Guru's" statement about the size/eff/power for that small factor PSU...

 

[Bill_Bright]

not sure why bill bright so excited about yoru post so excited about how gold is the max anyone should get

And I don't understand why you and a few others think it is proper to misrepresent what others say. It really is deceitful and disrespectful to the site and everyone reading. Are you not capable of just debating the facts without misquoting or interjecting personal criticisms?

Liking a post does not mean someone is "so excited" about it. If that is true, then I guess you are "so excited" about my post #41 above.

I liked Zach_01's post because he was exactly right. It was because that particular 750W PSU you were referring too is a SFX PSU and just like a laptop case, the smaller size of the SFX PSU case puts greater demands on cooling. Since most PCs are not SFX and don't use SFX PSUs, that example you put forward hardly sets the rule. And that was what Zach clearly demonstrated.

FTR, I NEVER EVER said Gold is the max anyone should get. I did said I recommend no higher than Gold. Did you note where JohnnyGuru even said higher is not worth the cost? A simple search of this site would even show where I have said, if you can find a good deal, go for the higher certified PSUs.

Sorry, but I like to be exact to avoid misunderstandings and such type of things..

This is a technical discussion in a technical forum. Being exact to avoid misunderstandings is a quality trait. Nothing to apologize for, IMO.

 

[Dinnercore]

For you people over there in the magic wonderland of free energy it is not cost effective, but over here we march straight towards 0,40€ per kWh (~0,44$). If this trend continues the additional cost might pay off in a couple of years
Running my PC currently costs me 325€ per year (9 hours average per day), due to regular rendering workloads. A 5% efficiency increase (Gold to Titanium) would save me ~15€ per year. I typically use my PSUs for 5 years+ that adds up to 75€+ difference. Okay Gold - Titanium is not a straight 5% benefit, but still I´m already dead even when it comes to cost effectiveness of Gold vs Titanium.
EDIT: Thinking about it, I´m far from profiting of my Titanium rating tho. Since I don´t run in the peak efficiency range due to oversized PSU.
