My new graphics card needs an 8 pin connector but my current one has 6 pin only. Do I need a new PSU?

[Rytis2]

I decided to replace my GTX 960 Mini with a GTX 1070. The product page for my PC says I have a 600 W PSU but I can only see 1 6-pin connector that's connected to my current card. See image: 

I read that such adapter is not recommended.

So do I need a new PSU?

My specs:

Intel Core i7-4790 (4 cores) up to 4Ghz
2Tb SATA3 7200rpm
16Gb DDR3 1600Mhz
DVD-RW Super Multi
ASUS GeForce GTX960 2Gb GDDR5
600W Silent PFC 12cm (I guess it's this one)

[LukeSavenije]

well... that adapter isn't the problem

 

but that psu. boy that seems sketchy. get a new high quality one is my recommendation

looks like you have molex, there are adapters for molex to PCIe.

 

this is just an example of an adapter you could get https://www.amazon.com/CableCreation-GeForce-Gigabyte-Sapphire-Graphics/dp/B078W7W8L2/ref=sr_1_4?ie=UTF8&qid=1547630242&sr=8-4&keywords=molex+to+8+pin+pcie

[Spotty]

I'd replace it. Any "600w" PSU with only 1x 6pin PCIe connector is likely to be trash. Out of curiosity is there any labelling on the other side of the PSU?

Your i7 4790 + GTX 1070 will only really require 300W max. You could get a decent quality 450W PSU to replace it.

[Ic3d]

i think what you have is a re-branded LMS Power unit like this one: https://www.ebay.co.uk/itm/I-CHOOSE-LIMITED-LMS-Data-X750-750W-ATX-PSU-Switching-Power-Supply-with-12cm-PC/183500895347?epid=16021955024&hash=item2ab9817473:g:se0AAOSwWW5b0Dg9:rk:2:pf:0

 

i had that exact unit with a 4790 and a 1060 and i was playing ark survival and my pc just died and all the fans stopped spinning, after 2 weeks of trouble shooting(this pc had more points of failiure than usual as it was a re-purposed oem unit), i worked out that the psu had blown and taken my motherboard out with it. in total the £20 psu lead to me needing a £60 motherboard replacement and a new £40 psu. overall i would get off that unit asap and move to somthing like an evga b-stock unit for £30.

it seems to be a ewent 600w power pfc professional, but they are hiding the label in every single picture. this seems to be really sketch...

guys, look at the amount of dust buildup on the PSU and other components. He's had it for a while. His PSU is probably fine. 

an adapter is way cheaper than a new psu, GPUs used to come with these adapters even.

just because i havent died yet doesnt mean im not going to die, it could be later today it could be in 60 years but having good healthcare (in this case a good psu) will certainly help reach the 60 year mark.

Only "AC 220 V / 50 Hz"

 

Yeah I have this PC for about 3 years I think if not more. So would you say my linked adapter would be OK (at least temporarily)?

maybe for a few days  to a couple of weeks but no more, a much better sulution if to get a new psu from here: https://www.evga.com/products/productlist.aspx?type=8

 

some of the psus are going for $20 which is only about $17 more than geting the adapter but gets you a much more security and peace of mind that your new gpu will be fine:)

Very bad advice. No way that this power supply is able to supply 600 watt on the 12v rail while only featuring those connectors.

I would say don't go with a 6 pin to 8 pin pcie adapter, you're probably safe going with a 2x molex to 8 pin or 6+2pin PCIe adapter

 

This is because 6pin is 75W while 8/6+2 is 150W

 

6+2 is where its an 8pin but 2 of them are able to be disconnected.

 

 

If you want to freak out and get a new PSU thats fine. but if it has served you fine for 3 years, you're probably fine.

i would rather have one of the 600w 80+ white evga b-stock units than a no-name unit

true. but i would rather pay another 10 dollars for a cxm than a meh psu with a one year warrenty

me too but in this case, i was just assuming that OP wanted to spend the least possible, but you said the cxm psus are better.

No. Keep using your GTX 960 until you get a decent PSU.

If you like we can help you find a suitable PSU. What country are you in? I'm guessing Europe/UK if it is a 220V unit? India?

if you have money for a good gaming pc, you have money to keep it safe. 30 bucks for not letting it die in a couple years is nothing. when a psu dies, it almost always takes something with it

if you cant afford much go with this: https://www.1a.lt/kompiuteriu_komponentai_tinklo_produktai/korpusas_ir_ausinimas/maitinimo_blokai/corsair_atx_231_vs_series_350w_cp9020095eu

however i would reccomend this if you can afford it: https://www.1a.lt/kompiuteriu_komponentai_tinklo_produktai/korpusas_ir_ausinimas/maitinimo_blokai/corsair_vs550_550w_cp9020171eu

I'll have a look and see if there are any decent units available at reasonable prices.

@Stefan Payne might be able to help recommend something, as I see quite a few cheaper Xilence units however I'm not familiar with which specific models are decent and which aren't.

Don't buy that. Spend the extra 4 Euro and get the modern 'grey label' VS.

Another budget option would be the Be Quiet System Power 9 400W

https://www.1a.lt/kompiuteriu_komponentai_tinklo_produktai/korpusas_ir_ausinimas/maitinimo_blokai/be_quiet_system_power_9_400w

 

These are also reasonably priced

Pure Power 10 400W - https://www.1a.lt/kompiuteriu_komponentai_tinklo_produktai/korpusas_ir_ausinimas/maitinimo_blokai/be_quiet_pure_power_10_80plus_silver_400w

[Rytis2]

Thank you very much for the suggestions. I will look into upgrading (maybe a bit later). Some say that PFC is active and others have it passive. Is this important? Which is better – I guess active?

only 28a on the 12 volt... like i wouldn't have guessed it wasn't 600 watts continuous. there's a psu tier list down my signature. i would recommend at least tier c

[Mycielski]

Mate, throw that PSU right away, and get a decent one from a reputable brand! I would go with 500W or so, for upgrades down the line!

Active PFC btw, that's a "must have" feature nowadays...

I would go with this one, from the store that you linked: https://www.1a.lt/kompiuteriu_komponentai_tinklo_produktai/korpusas_ir_ausinimas/maitinimo_blokai/be_quiet_system_power_9_500w
