I HAVE A 6PIN IN MY MOTHERBOARD AND MY POWER SUPPLY HAS NO MORE CABLES FOR MY NEW GRAPHIC CARD

[Zakariaa]

I have the hp elitedisk 800 g1 tower with I7 4790 and i just bought a new RTX 3060 eagle from Gigabyte but my PSU has no power cables left, So I went to buy a new PSU but I didn't know what to buy because my motherboard have only 6 pins for power and another 6 pins for sata power. Can i get some help ?

If  it's an OEM non standard board you're screwed, have to change everything... or make a FrankenPC, buy another PSU for the GPU and jumpstart it

That's why those prebuilts are a bad idea

that sounds like a proprietary motherboard, and you won't be able to buy an off-the-shelf unit to replace this one.

does it have any PCIe cables at all? for a PC like this, you might consider replacing the motherboard (if the case does not have non-standard mounts and such)

LGA 1150 motherboards with standard connectors can be had for ~$35 on eBay. I would just get one of those and dispense with all of the HP bullshit.

Of course, this platform is almost 10 years old, at a certain point you have to ask yourself if it makes sense to keep putting money into running a system with a 4790.

Yes that's the same as mine, what should I do ?

Buying a PSU only for the GPU ? So my pc will have 2 PSU ? I don't know about this, are u sure because I'm afraid to lose my new GPU. 

If this can work without any problem, what PSU should exactly buy for RTX3060 eagle ?

It might be disgusting for ya but for me this is a legend, pc's prices in my country are so high and I can't afford that budget for a pc, the RTX 3060 price in my country is 440$ or higher it can be more like 600$. 

[Kilrah]

There are 24pin to 6pin adapters around.

as @Middcorementioned, you can swap the motherboard for a cheap one such as a used B85 board and get standard power connectors. Then you can use basically any power supply you'd like.

Now that I think about it I would worry about weird front panel connectors on the HP case. So then you're buying a new case...

Im not doing that, I will just buy a new PSU only for the gbu I think this is a good solution

Yeah sorry was kidding 1st world style

Where do  you live ?

Wow, so this is actually quite simple. First off, return the Rtx 3060. It makes no sense. You have an i7 4790, it's an old CPU that cannot possibly hope to keep up with a Rtx 3060. 

 

Now, let's get a REASONABLE gpu for the system. You will want something that's using a single 6 pin or single 8 pin. The Rx 6600, Gtx 1660 models (ti is the best, followed by the 1660 super then 1660), and Gtx 1060 6gb are the cards you should choose from. Depends what pricing is like on the used market in your region as to which to pick. Don't buy a brand new Rx 6600, too much money. Stick to used, and really the 6600 isn't worth much a premium over the 1660ti in this case because the CPU is gonna be the bottleneck. These GPUs are all in the 120w-130w range, something this PC can handle with the current PSU.

 

Now, to power these cards you will need a 6 or an 8 pin. To get that, you use a dual SATA to 8 pin (6+2) adapter. About $5-6. Like this: https://www.ebay.com/itm/184834291436?mkcid=16&mkevt=1&mkrid=711-127632-2357-0&ssspo=C_pEmDIxSEO&sssrc=4429486&ssuid=5uuha8tgrd-&var=&widget_ver=artemis&media=COPY

 

DO NOT USE THIS ADAPTER TO TRY AND POWER A 3060, the 3060 uses too much power and if you burn down your house I'm not responsible.

Depends entirely on workload. There are many scenarios where that CPU will keep up with a 3060.

Why would you suggest the objectively faster (on PCIE 4.0) 6600 over the 3060? That's a PCIE x8 card, not a x16. It's going to suffer on Pcie 3.0.

Pci-e 3.0 x8 is perfectly fine for a Rx 6600. In that video you attached, it's mostly a 1-2 fps difference on average. It's not a problem. 

 

The 3060 is simply overkill AND it draws 170w. Too much to be done safely this way. Cannot reccomend it. In gaming? It is overkill. It just is with this cpu.

 

Therefore, I stand by reccomendation of a Rx 6600 or a Gtx 1660ti with the other options I listed as alternatives depending on pricing.

 

Also, you're looking at a 4790k running at 4.4ghz. OP has an i7 4790, that runs at 4ghz. 400mhz clock speed is a pretty significant difference on a product of this age.

Except the 33% of games there where it was much larger than 1-2 fps

On average yes. What about the power spikes that go beyond rated power?

I know that my CPU is very old and can't hold a RTX 3060 but I don't need it for games, i bought it for my 3d softwares like blender.

I was rendering all my works using the I7 4790. So I thought buying a good graphic card will help me with that.

It is a good card for that. I don't recommend that you get a different card but I do still recommend that better motherboard.

^^^^

 

One of the major reasons why I build DIY systems at work to replace workstations instead of buying OEM systems. Simply not worth it anymore with non standard motherboard+cases, which almost always require proprietary power supplies. Some of the OEMs have moved to 12V only, so the 3.3V and 5V are handled by DC-DC busses on the motherboard. This makes them expressly incompatible with any off the shelf PSU. 

 

You might be able to find a higher wattage version of your power supply to support it. The other option is to run the GPU off the new power supply and simply hotwire start it, aka, you're running two power supplies.

The reality of PCIe 4.0 8x cards in PCIe 3.0 capable systems, outside of a 5800x3D in a B450 motherboard, you're likely to be CPU limited before reaching an FPS limit due to PCIe bandwidth. In the tests I've seen, its a title specific limitation that can be either substantial or non-existent when testing without a hard CPU limit (downgrading a PCIe 4.0 capable system).

 

Regarding 4790 vs 4790k, +400MHz is like comparing 2 to 2.5, when modern CPUs are in the metric of 10. Its still grossly CPU limiting even for an RTX 3060 (especially for multiplayer games), but is better than nothing.

 

 

I even pulled out my 4790k recently and threw my 4090 in it. Mind you, this was as good as you could get for the platform, since it was running a 240mm AIO and 500GB PCIe 3.0 4x Samsung SM951 AHCI M.2 drive, which also chops the PCIe lanes down to 3.0 8x (Z97 Impact motherboard). 

 

 

 

Playable experience, but not great. Better than no experience though. Still surprising that even the 4790k was at a CPU+GPU limit at 500 fps in the best case scenario for the game's engine.

 

 

TLDR: 4790k dropped the maximum framerate in the most commonly limiting scenario to <90 fps compared to 240 fps, mind you, that was choppy enough to be irritating. Still able to hit 90 fps, but this is in one of the most optimized games I've ever played that can genuinely reach 1200 fps.
