XT 6650 OC with a 550w PSU?

[Matxe92]

I'm a little unsure whether i can install a XT 6650 OC from ASUS, in my system when i got a 550w Corsair PSU, without destroying my system.
ASUS recommends a 650w.

I've tried calculating the wattage at several sites, sometimes using the XT 6700 because they don't have 6650 in the database.
It comes out at like close to 500w minimum requirement.

My system otherwise has a standard I5 - 11600K, 2x 8gb ddr4 ram.

Should i listen to ASUS recommendation, or can i just go with what i've been able to gather from calculating it?

You should be fine, our review of an overclocked MSI card (Gaming X) showed that pushing the card to the limit beyond gaming only had a 200 watt draw and therefore the review recommended a minimum 500w PSU, obviously PSU quality also can be a factor though, other factors could be if you for example have maxed out the power limits for your 11600k which would significantly increase the PSU's power draw, take a look here ....................

I'm running an overclocked 6600XT and a 5800X3D on a 500W PSU and there's no issues. The system consumes 300-350W during gaming, ~400-450W during CPU + GPU stress tests.

Yes you can.

In case you're paranoid you can force the card to work at stock clock -200 MHz so it'll be easier on the wattage and you'll be perfectly fine without losing a lot of performance. This addresses 20 ms spikes issue greatly lowering their amount and severity. Mean TDP of that card is not enough for your PSU to go FUBAR, the only issue is spikes.

Oh and don't forget to turn V-sync on in every game where it doesn't ruin the gameplay. You will save another dozen or couple dozen watts on that.

Many thanks for providing that. You guys have some great answers on here.

I've done no fiddling with the CPU and i checked last night during gaming, it was eating 129w at maximum.
I'm running dual monitors aswell, and the it's a Corsair vs550 PSU.

I suppose that still falls within doable without frying my system?

That was an idea / question i had aswell, if that was possible to "downclock" if that's a word.
Because i am slightly paranoid as frying the system is a complete no go at the moment.

Supposedly i could prior to running any game downclock to regular clock speeds then?
Where do i get those speeds though, would that be from AMD's site?

 

[Tatty_Two]

Maybe download HWinfo and run the sensors tab minimised whilst playing a game then you can check both the CPU/GPU power draw, depending on what you find there are a number of options, the simplest of which would be to (for example) to lower the TDP limit of the graphics card in something like MSI Afterburner to say 90% but obviously you need to establish a starting point through monitoring.

Obviously there is little need to do anything if you are only pulling 129w with that card, if so I am assuming you have Vsync enabled?

 

[Beginner Macro Device]

Yeah. Run AMD control panel and go to "Performance" tab. Then commit to the manual tuning, select "I understand the risks" or whatever they put there, I don't quite remember lol, and lower the Max clock by 200 MHz (you need to enable fine tuning beforehand). It doesn't really matter what exact 6600 XT you have, their clocks differ by negligible numbers. 200 will be fine in any case. Press "Apply" afterwards so it saves the settings. Min clock is recommended to be set at -100 MHz mark compared to Max clock but I personally have never seen any difference between letting it 500 MHz and making it almost as high as Max.

This is an example how it looks with my 6700 XT. Your clocks will be higher than those, 6600 XT has higher stock clocks so don't you worry.

There's absolutely no need to underclock.

Already have HWinfo installed, that's where i got the drawing power number for my 11600k which was 129w when gaming.
Was "card" a typo, you meant the CPU right? The 129w was the CPU power draw when gaming.

Adjustment of power was not allowed on the XT 6650 according to you guys review i read?

There's absolutely no need to underclock.

Probably not...unless that ASUS card does something crazy like maybe draw 300w, i would start to be in trouble i think.
Assuming i just add up the TDP values when gaming from my components. 129+300 plus the xtras in fans and SSD's, that's probably still under 550w.

 

[Beginner Macro Device]

something crazy like maybe draw 300w

It's borderline impossible on that SKU. You will need to mod its VRM and controllers... It just can't "eat" more than 200–220 W. Trust me, I had a bunch of 6700 XTs to experiment with. No single card reached the 300 W mark, the hungriest being 47 W behind that number. 6600 XTs are even less taxing on PSU.

I was going to tell you to get HW64 and see what the 12V rail is dropping to, if it is falling below 11.500 (About 5%), I would get another power supply. Good places to look, are at manufactures outlet stores, like EVGA. You can get some grate price breaks, like I did on an 850GM SFX supply for 75$ US.

Does it really matter, 550 watts are 550 watts regardless of what it's intended for. Sure it might be loud and warm, but that's ok.

Yeah it does from a reliability standpoint and not to smoke parts.

You came here asking a question and you went with a bottom barrel psu that is on the verge of a raidmax.

With my old GPU it dropped to 11.664 at it's lowest when gaming. Obviously no clue yet, what the new one will be. I suppose the same?

Why would it smoke parts, and do i strictly have to change PSU do you think?
Again, i'm fine with it being loud or whatever. The crucial part is that it's not gonna damage my components.

High quality PSUs lead to longer lasting components because voltages stay within spec.

Ripple, spikes, etc. All worse on a crap PSU which is what you have.

Performance can also be better with a high quality PSU because components run cooler and with cleaner power fed to them.

Rule #1 of PC building is don't skimp on the PSU.

It's a mistake many people make, thinking the Watt number is all that matters, and looking to save a penny here and there, putting everything into CPU and GPU. PSU can last 10+ years, and affect the system for that entire time. Not to mention the efficiency difference between an 80 and a 90% efficient power supply, extra heat dumped into system and electricity bill etc.

The sheer amount of problems a bad PSU can cause, that are very hard to troubleshoot...

Also one of the main reasons most prebuilts are crap and overpriced, they skimp on PSU, motherboard (power delivery) and cooling.

And no, 550 W are not created equal.

A cheapo bottom barrel PSU may only have 400 W or even less on the main 12 V rail, with the other rails 5 V and 3 V providing the rest of the "550 W".

What line from Corsair would you recommend for my PC? As budget as possible.

Check our reviews. The info is all there.

"As budget as possible" is the wrong attitude by the way, this is the component your entire system relies on.

11.6 is a sign of deterioration

There are others besides corsair, there is Seasonic,Super Flower, EVGA, Enermax etc.

Just avoid cs, cx, vs, vx from corsair, stick with RM/RMx and HX

It seems like i probably have to surrender, lol. I had no idea there was relevant quality differences between PSU's.
Not being able to provide the correct volts does seem like a problem.

I've looked at Corsair CX650F. You guys gave CX750F decent review. Would that apply to CX650F aswell, i really don't need 750w.

 

[freeagent]

Its best not to abuse your PSU. If you run it at its limits a few times you will notice its rails start to sag a bit. That would go for any PSU tbh. They don't like to be over driven.

 

[ASOT]

Hii there,

The heart of pc is Psu,going for better is essential,system stabylity and long run

Is not always important Wattage,good 550w-650w gold RMx or Seasonic suggest.

Peak efficiency is 50% load, so if your system uses 350-400 W, a 750 W PSU is ideal, they also degrade over time reducing their output.

 

[sLowEnd]

It's fine. I'm running a 6650XT with a 550W TX 550M. (This model https://www.corsair.com/ca/en/p/psu...watt-80-plus-gold-certified-psu-cp-9020133-na)

Edit: The VS550 is a fairly old, lower end model. If I were in your shoes, I'd switch it with something better.
