Can my psu hx750i catch fire / explode if its not strong enough?

[w33dhit]

Hello. 

 

Im getting msi gaming rtx 3090 trio next week, and all psu over 750 watt are sold out here in norway.. my current psu is hx750i, my question is with my current specs can my psu or any other pc parts catch on fire or explode if my psu isnt giving out enough power? I have googled a bit and peolpe say that bad quality psu might do so, and mine is good quality but low watt..

And no i wont overclock until 1200hxi psu is back in stock in my country but im scared to blow this pc up ..... Here my specs:

Msi meg z390 ace motherboard

i9 9900k

Msi geforce rtx 3090 gaming trio

32gig g.skill tridentz 3600mhz

Nzxt kraken x72

Corsair ll120 fans ( 4 of them ) 

Corsair ll140 fans ( 2 of them )

Corsair commander pro

Corsair hx 750i ( 750 watt psu )

samsung 970 evo plus 1tb m.2

samsung 970 pro 512gb m.2

Creative soundblaster z

corsair 570x rgb case

 

i was thinking maybe if i remove corsair commander pro and turn off all rgb lights may be a small hope?

 

thanks for any replies !

It won't catch fire as it has protection circuitry, it will just shut off immediately when too much power is drawn e.g. stress test

Because they cheap out on protection circuitry and proper cooling for IC's e.g. heatsinks and everything is not rated for what they say

Okok then i do not need to kind of worry for fire or other parts be damaged ? I can kind of push all parts in pc and start pc and like... Not worry ? Cause my worry level is like 11 out of 10 no explosion ???

BTW, you could just get the 1000w version,(here). It would be enough.

Made by a reputable brand, should be fine. If it is not enough, it will power off or BSOD randomly

With the 3090 you will almost certainly need a more powerful PSU, a 1000w model will be perfect for it

Okok thanks u for reply mate !!! Do u think if i buy the 1000watt i also can start overclock bigtime and there is will be enough juice ? I push my cpu to 5.0ghz, set the xmp profile ram, and smack gpu up to limit and is 1000watt be enough ??

HXi 750 will fine for that system. 

 

https://www.prisjakt.no/product.php?p=2768793

 

and the 1k watt version is available. dunno how much you were gonna spend on the 1200w version. 

 

or can allways grab the non-i version

whats your current cpu power draw? That would be the biggest thing. If its like 210w, its fine. if it's 250-300w, it may not be. THe 3090 can pull like 500 on it's intermittent spikes. Thats like 900w (no gpu oc and cpu pulling 300) on the psu, so it may hinge on how much the cpu pulls.

no, the 3090 spikes can be > 500w, and that cpu can pull 250 under a heavy oc. Thats 750w before everything else.

yes, and it will be fine. unless you for some reason do aida64 and furmark all the time......

Proshop has it and you get it in at a reasonable timeframe. order it now, and you will probably have it by Friday. and the 750w unit will work fine untill then.

In most cases, yes, a PSU by a reputable brand will be fine, but even reputable brands have their nukes! For example, EVGA makes the SuperNOVA series of PSUs, and many of them are pretty good, but their NEX lineup isn't amazing, and I wouldn't want their 400 W N1 PSU to occupy the same BUILDING as my PC (which, for a power supply, that dismal two year warranty should've been enough to make you reconsider).

 

I suppose a tier list is a fairly decent way to quickly look up if a PSU is good or not (A/B are good, C is fair if you're building a budget PC, D isn't good, and E is a nuke), but I always recommend looking at a thorough review of any product before you make your PC run off of it.

lol its like a storage but far away storage.. Hopefully the 1200i will come stock on monday and i will asap buy it ! Also , i tried to download corsair link but it only shows voltage ..

Also what i saw was that the hx1000 is in stock without the " i " at end, but if im going to put that much money in the psu ill just wait for the hx1200i , and have patience while the 3090 will sit infront of my face.... but if i know myself right i will install it and hope for the best.... lol...

yeah that one u just send is without the " i " in the end, and if im going to put that much money in that psu i will wait and have patience ( if i can ) and just roll with the one i got now till rest is in stock. i really want the hx1200i so its kind of future proof too, as i have read with ur guys comments, i have good hope that it will work for the time being if i dont push my system hardcore... wich.... i might..............

just dont put and overclocked CPU on full load and full load 3090 at the same time.

if you want bonkers PSUs. just for a little extra, there is something neat you can get:

https://www.prisjakt.no/product.php?p=5533918 the DPP12, but at that point you might aswell just get the 1500w version. 

 

https://www.prisjakt.no/product.php?p=5533917 which is actually in stock over at Multicom. but at that point you could almost just go for the best PSU on the market. 

 

https://www.prisjakt.no/product.php?p=4652296 this being pretty much the undisputed best PSU on the market atm. that you can easily get your hands on

 

 

edit:

 

worth noting you can just get a cheaper Straight Power 11 or similar, which you can essentially keep and use for the same ammount of time as the HXi without issue. same with the non-i. unless you really want the iCUE features, there isnt a notable reason to get the HXi

no, it happens under gaming loads too. Ans still, even after the bios update.

are you reffering to the transient issues related to the 3090 that the HXi isnt affected by?

 

because i can point to 650w powersupplies that can run the 3090 just fine, and that would include a theroretical 650w hxi

Your HXI 750 will be fine for now.

 

Start overclocking and pushing that 3X 8 Pin 3090 and you may run out of PSU depending however.

 

I have a 3X 8 Pin 3080 with a 450W VBIOS so I have some idea of what these things can actually pull, or the whole system for that matter. That's 1st hand experience, not theory or from some post or YT video someone watched.

 

Yes, you can run out of PSU on the 750W you have, and it won't take very much effort either once you start overclocking.

 

for know it will be fine as I said.

650W really won't, I don't care which one it is, people saying they are either completely and totally FOS or they are under volt the hell out of them so they may as well just throw the GPUs in the trash if that's what they are doing because they are morons. 

 

A 750W is really pushing it for those 3X 8 Pin 3080's and 3090's, especially ocing and or with those 450W/500W+ VBIOS.

 

The OP is getting a 3X 8 PIn 3090....

yeah i wouldnt suggest overclocking the high powerlimit 3090s on these "mid wattage" PSUs, doesnt change the fact that there are 650w PSUs which can run the 3090 without issue. its not ideal, for a couple of reasons, but it does work.

If they under volt them or they are the two 8 Pin vers. then maybe on a good day if the stars all line up right....

 

Other than that no way, they are testing fate and asking for trouble and it's coming for them...

 

And NO they will not NOT run a 3090's without issues in all cases.

well, not really. you just need the right 650w powersupply. tho offcourse running something like a 9900k or 10900k at the same time really isnt a bright idea.

i wouldnt claim that either.

i would say its fine assuming they arent pushing wattage or are rutting other high wattage parts in conjunction.

Send me that magical 650W PSU and I will show you how easy it is to overload it... Under my normal use. 

 

With my system and 3080 FTW3 Ultra.

dont really have access to something like a Whisper M. so cant exactly do that. 

 

and it can certainly be overloaded.

yeah i can see that system being able to overload it.
