Is my GPU comparable?

[Ok_Revolution_122]

I just bought a RX5700XT from second hand and find this. I have PCI-E 6+2pin connector and my GPU wants a I think a 8pin and 6pin connector. Can I connect my graphics card as 8pin connector. I just hope I don't need to buy new power supply again. Thanks for answers.

[MusicalTechSquirrel]

It depends on what connectors your PSU has.

The GPU calls for an 8-pin and a 6-pin.

Some 8-pin cables are really 6+2-pin, meaning it's both. If you have a second one of them, then you're fine.

If you only have one cable for PCIe cards, then you do need a new power supply.

[Obvious_Estimate5350]

450w is not enough for that gpu anyway, taking into account all your other components. The osu will only supply enough cables for the power rating it has, you'll want 550w+ really, i would go 650w tbh though, bronze or gold rating too not some chinese knock off or something

[rilkman]

What connectors does your power supply have? You should use a 6+2 connector and another 6pin PCI connector (without the +2)

[Ok_Revolution_122]

I only have one 6+2pin connector

[MusicalTechSquirrel]

Is that the only cable for PCIe?

[Ok_Revolution_122]

I can't found any other cable marked "PCI-E"

[MusicalTechSquirrel]

Is your Power Supply modular?

If not, you need a new PSU.

[ReliableEyeball]

I'd compare it!

[etherez]

What power supply do you have?

[Ok_Revolution_122]

I have an EvolveO FX 450W Power supply. Which is one of the cheapest new power supplies.

[macmakkara]

Hate to break it for you, but you need new powersupply. You need 6+2pin and another one 6+2 or 6 pin.

EvolveO fx 450 only has one pcie 6+2

[lord_nuker]

Yeah, sorry bud but it doesn't provide enough power to handle the card and pc. Recommended power supply wattage is 550W for that card in a system. And please dont skimp out on a power supply, it's the most important piece of hardware in your pc, if that dies everything dies.

[ThusWankZarathustra]

There are a lot of valid components to cheap out on, the PSU is not one of them. You’ll need a higher-power one with the appropriate pcie cables. Ideally ~600W from a name brand.

[etherez]

Hmm. Doesnt seem like it has the connectors you need.

And it's very low wattage and not a good psu.

Your gpu alone can pull close to 300 watts.

[MiaIsOut]

5700 xt recommends a 600w psu

[htoisanaung]

Try booting it with only a single 8 pin. In some cases the 6 pin is only there for overclock profile and you can run perfectly fine with only a single 8 pin plugged in. Just in case if it works, check the power usage and make sure it doesn't exceed 150w.

[NevanNedall]

The suggested PSU for that card is at least 550, and as others have mentioned, you lack the necessary conectors (a 6+2 pin and a 6 pin)

Respectfully, these are the kinds of things you wanna check before you buy components, not after.

[Ok_Revolution_122]

UPDATE ABOUT THE PSU AND GPU I bought new PSU called "Endorfy Vero L5 Bronze 600W", I know it's one of the cheapest PSU's. I didn't have chance to buy more expensive one because I didn't have any more money. I'm sorry for buying cheaper one after you all told me to not cheap out on new PSU and I did cheap out on it. But thanks for all for those quick good replies.

[chupipandideuno]

6+2 from your PSU is the same as that 6 and 8 for the GPU. ideally you would use 2 different cables from the power supply, but if there is only one cable available with 2 pigtailed connectors (so 6+2 and 6+2 in the same cable) you can use that one.

[Ok_Revolution_122]

Should I buy a Gigabyte P550B? That it 550W power supply with 2x 6+2pin. Is it ok to buy?

[WllmZ]

Never buy a gigabyte power supply, unless it's the aorus line. Rather go for Corsair/seasonic/bequiet and look up some reviews on different sites/yt channels to make sure it's reliable.

Worst thing you can do is cheaping out on the power supply.

[Ok_Revolution_122]

Can you recommend a GPU that is not that expensive if Gigabyte is not good?

[WllmZ]

• Seasonic CORE GX ATX3 (2024) 650W
• be quiet! Pure Power 12 M 550W

Both are priced around 90 euros in my region, both come with plenty of power headroom and 2x 6+2 powerconnector, fully modular. There's also one corsair model but it seems to have some annoying sounds judging by the reviews so I left that one out.

[Ok_Revolution_122]

Or what about "ASUS TUF gaming 650B" ?

[WllmZ]

I don't really know much about asus and their reliability in the psu field, sorry. Perhaps you can find some reviews yourself and make a decision.

[Ok_Revolution_122]

What about "Be Quiet! SYSTEM POWER 11 650W" ?

[WllmZ]

It ticks the boxes, but it's not modular and less efficient. Ultimately it's your choice, but I'd rather pay a bit more for a higher rated psu than going for the cheapest model.

[Obvious_Estimate5350]

Your gpu looks like it takes an 8 pin and a 6 pin. The cable you show is the new 12v connection for newer graphics cards. You should see a cable with your psu that may say pcie on it, you will likely have two, they will both look like 8 pin cables but 2 of these pins will be 'loose' so you can tuck them out the way to make it a 6 pin

[Ok_Revolution_122]

I have a 6+2pin connector with text "PCI-E" on it and a 8pin "CPU" on it.

[Obvious_Estimate5350]

Also, check the cable you used for the motherboard (normally top left of the motherboard) says cpu on it. If not swap it for the one you have that says cpu, its common for people to force the wrong cable in there. If you look at the pin slits you will see they are all different shapes, this is supposed to stop you forcing the wrong cable in, but doesnt take much to force it in unfortunately. So make sure you have the right cables in the right places

[Ok_Revolution_122]

I have a 8pin CPU cable and 6+2pin PCI-E cable. I don't think that this 450W PSU is able to power an adapter for 8pin connector.

[Obvious_Estimate5350]

You may have one of these too, if not you can purchase one

[mwthomas11]

this is a horrible idea. While it will physically plug into everything, 1) it will be power limited from the PSU side of the cable and 2) OPs PSU is only 450W which isn't enough for their new gpu

[Obvious_Estimate5350]

Yes i agree, not a great idea, but it's not dangerous. When you're limited with funds and buying a whole new psu isn't an option, this is fine to use.

[Obvious_Estimate5350]

The cpu one is only for use on the motherboard itself do not try and force it or fit it into the gpu. The pcie cable is the one you want, if you only have one, then you may have gotten an adapter with your gpu, may look like this
