Hello i want to buy an HD 7970 GHZ edition it has 1x8 and 1x6 pcie power connections but my psu has only 8 pin,what if i use an 8pin to 2x8pin psu splitter will it work? it says it draws lower than 300 watts

it depends on your PSU. If it is a good quality unit, should be no problem.
But if it is a "normal" one, there might be a problem. the 8pin PCIe in computer is rated for ~150w. you want to push twice as much. connector/cables/or whatever inside the PSU can simply melt.

one more question will an r9 270x do with pcie splitter its 180W and it should be enough for my motherboard,my motherboard is an tomahawk arctic B350 (which i didnt mention) psu is a thermaltake bronze 450w tr2 with sleeved cables and the gpu takes 2x6 pins i want basically to convert 8 pin to 2 6 pin is that safe???

The advice so stands that you shouldn't use adaptors, two reasons.
1. Sometimes they are poor quality
2. There are no psu's designed to give the output needed that don't have the connectors.

Get a good quality psu. There will be psu's that have the outputs that should not have them.

i will get a r9 270x and split it to 2x6 pin which wont make any problem and psu is ok it has sleeved cables and its 80+ bronze which isnt a bad quiality one and belive me nearly all psu's are made in china you cant escape china,btw thanks for the help im ready to buy an r9 270x with a psu y splitter

80+ is an efficiency std not a quality std. Sleeved cables are irrelevant. Where they are made is irrelevant, it's the design that's important.

It is a very bad idea to use splitters. It's your house fire, not mine.

god now i got an hd 7970 not ghz and im sure it wont take a lot of power,pcie splitters are fine its just the resistance you push too much power through the one cable i hope the cable's resistance is high enough so it wont fry anything or melt the cable because of high temps,and i will see if i get a better psu full load is nearly 275Watts and ay HDD takes about 10 watts ram another 15 watts cpu takes 40 watts so i dont think its overloaded and i have enough space if thats realistic power consumption but as i said the problem is the cable too much power will be pushed through it and if resistance isnt high enough it might fry the gpu or if im lucky melt the plastic, i have another problem too,my psu fan doesnt fit the grills of the case (it faces down) and only 55~75% of the fan is not covered i dont know if this is a problem and the psu is screwed correctly

If you don't know that you need low resistance and not high, then you simply shouldn't have an opinion as to what will or will not work. Don't use splitters, if your PSU doesn't have the connections it's for a good reason. If you think I'm being harsh I'm trying to stop you ruining all of your kit.

i mean why it will fry the gpu? it isnt a 500watt one if it was i would get a new psu but seriously? like how much power will the gpu draw i dont think its like 600w like wtf its an hd 7970 its not an 7990 and how it will fry my gpu? it needs to push high voltages upper its limit to fry it and it wont fry it it will just kill the psu in that case and i dont have so much money to get another psu if i get those cheap ones 30-40 euros they would be fried in a second like the gpu lowest is 500w but actually it takes 315w max as i see on benchmarks 40 for the cpu 10w for hdd i have space the only thing thats causing the problem is the pcie splitter not the actual psu the psu is fine 450w and i wont overclock anything and if the power draw is the problem i can set a powerlimit through msi afterburner which wont draw much power from the splitter and what powerlimit shall i set it to? im fine with a powerlimit until i can get a new psu

A PSU that dies can take other components with it.
I've had this happen personally.

Good luck.

i mean i can boot to windows safely and put a powerlimit as i said what powerlimit shall i set it to and you say that it will take other components i want the answer straight what shall i set the powerlimit to and if i take a psu hd7970 how much wattage psu requires and one question did you even read what i wrote? because you say if psu dies it can take components with it which i didnt ask for that

" it needs to push high voltages upper its limit to fry it and it wont fry it it will just kill the psu in that case"

Good luck.

GOD I SAID WHAT WATTAGE PSU SHALL I TAKE GODDAMIT!!! Did you even read what i said or you are again blind i want a straight question what wattage psu shall i take goddamit and you didnt anwer it and be irony to me you dont know from psu's then if you are like that

1. lose the attitude, or leave.
2. we've been arguing with you for 4 + days now about pci-e adaptors, and you've finally understood the message
3. a good quality 600W PSU will see good for the next decade of single GPU builds, a good quality 50)W will see you though most GPU and CPU combinations, but not all
4. take note of good quality, not all 600W PSu's are equal
5. you need to learn to take advice and not believe that you know more than people who have been building PC's for a lot longer than you
