Hey guys im planning to buy an xfx hd 7770 double dissipation. but

my screen resolution is only 1920x1080 i readed that those cards are cheaper and faster than the hd 7770 on the resolution 1920x1080.

i want the best card for 1920x1080

but i can only choose from those

Palit GeForce GTX 650

XFX Radeon HD 7770 - Double Dissipation Edition

whice one is faster ? on screen resolution 1920x1080 ?

here are my pc specs

=================================
PC SPECS
=================================
CPU : AMD X4 640
PSU : 600Watt

go for the 7770.
December 10, 2012 4:59:24 PM

only the problem is im using now an 350 watt psu

i want a 600watt or more.

but if the powersupply from 600 watt or more does not have the pci-e power cable. are there existing adapters from molex to pci-e power cable ?

im bringing the news paper around on the industrial of my village.

on the industrial i always talk to a guy that does know a little bit of computers.

that guy has a company where people of the village can throw household items away

like computers they can throw away for free. but other stuff they need to pay.

i can ask him if he can get a 600watt working atx power supply

the problem is my last work day is before 1 january after that the company is sold for what im paper doing. that company that has bought this company over. have its own deilver guys so i will be workless

:S damn, sorry to hear that, well, most graphic cards come with adapters for the 6pin, if not, maybe you can buy the adapter yourself they are cheap: http://www.newegg.com/Product/Product.aspx?Item=N82E168... i guess that should work.

Please check the brand as well as the labeled 12 volt amperage of the 350 watt power supply. A quality(it has to be good, not some of the junk on the market) 350 watt power supply should run a 7770.

They do make adapters from 2 x 4 pin molex to PCI-E 6pin power. Most video cards even come with them. They are not always recommended, but as long as your system is not power hungry, the do work.
December 10, 2012 5:33:31 PM

so you say a 350watt powersupply can even give the 7770 power enough

i know a graphic card will never use 500 watts its only recommended to have 500 watt to power up everything but

what im using is a 4gb ddr3 1600MHz memory here is the link for more info

can you give us a little info about your current psu? or the model/brand of your pc (in case its prebuilt).

You will need to post the 12V current rating of your current PSU. If it is a very good 350w supply, and has 25A or so on the 12v supply it maybe able to work a 7770. Otherwise, you should try to get a better one (look for the most current on 12v rail), .

Its all about power. I had a 5770(more power hungry then the 7770) a i5 750(undervolted to save some power) 2 x 1tb hard drives and 4gigabytes and my DVD drive(it is a slot load laptop drive) of ram all on a little 300 watt power supply :) 

It is all about having enough 12 volt current for the devices you use.

That other system above is currently

i5 750
GTX 650 ti
H55n USB3 board
2 x 4gigabyte Corsair sticks
1TB WD Blue
Slot Load DVD
300 watt power supply :) 

This is not to recommend cutting things as close as you can, but the 7770 should take less power. A little undervolting and a good power supply could just pull this off.
December 10, 2012 6:00:02 PM

i will open my case and take a look on the sticker
December 10, 2012 6:08:45 PM

i think i have bad news

its an GPS-350EB-200

here a link for the sticker image
i dont know if it is the same sticker but the model name is the same

Well that makes it more difficult. I mean they do not have a 12 volts only rating meaning the the 12 volt rail is fully dependent on the other rails(while this is normal, they do not actually list the MAX combined of just the 12 volt lines.)

I would guess in the 200-230(maybe a bit more) watt area can be pulled from the 12 volt rails assuming the others are not loaded up too much. While that MAY work. I have not used that power supply to say yes or no.

That is clearly an older design as it has a PEAK and CONSTANT power rating.

My 300 watt power supply is listed for 264 watts @ 12 volts on its 2 rails.

I am just a bit worried about it failing on you. While with a lighter(the 7770 is not a power hog my any means) card it should be able to pull it off, I am not willing(for your sake, don't want to fry your system) to tell you to risk it.

I await others opinions here as well.
December 11, 2012 5:32:25 AM

so my powersupply cant power it up ?

December 11, 2012 5:43:14 AM

I agree with nukemaster, spend a little money now on a new psu rather than risk frying your whole system and spending a lot on replacing it.

I would link you, but I'm on my phone ATM. I know th has benchmark test results available. Try looking up your two card options there.
December 11, 2012 8:33:13 AM

okay

can i ask how can i fry my system white a powersupply that has not enough watts ?
December 11, 2012 8:48:57 AM

i dont understand i dont know much about it.

but what can go wrong if u buy the xfx 7770 double dissipation put it in my system

white the powersupply what i still use showed on the image ?

What happens with a power supply is it can deliver so much power and if you TRY to pull more a good power supply will shut off before going out of spec(I am not calling delta bad, it is just older and as power supplies age, they also loose some of the power rating, heat also effects them).

The problem is that not all power supplies gracefully shut off or fold over, Some will actually start to run the voltage out of spec causing damage to the system.

I have no way to make you a 100% guarantee because they do not list the absolute MAX for the 2 12 volt rails. They do list it as being rated for 290 watts over all rails and 130MAX for the 3.3 and 5. In a worst case scenario that would leave you 160 watts for the 12 volt rail. I would say it should be good for at least 200 watts at 12 volts as modern systems do not load the 3.3 and 5 volt rails as much, but have no good way to back that up.

In real world testing, my power optimized media center system has not passed 170 watts(I am sure if I worked hard at it, I could get more out of it) at the wall(leaving the DC power use around 150 or so watts), BUT I know the consumption of all those parts and the system was build around the power supply, not the other way around.

No one can give you a 100% guarantee that it will or will not work(My guess is it would, but as I said in another post, you "may" be cutting it close or those delta's may be like a rock). It is a different story when I want to risk my own hardware to try something vs me telling you do do the same.

If you are looking at power supplies, Please look at more then just the rated wattage look at the wattage or amperage that it can deliver on its 12 volt rail. I have seen too many 500 watt power supplies with LESS power then a good quality 300 watt power supply.
December 11, 2012 12:35:35 PM

oke

what about the techsolo tp-600 ?

but white this

so a 500 watt psu cant run a good graphics card properly but an 300 watt psu white white more ampere ?

The TP-600 power supply has 24 amps @ 12 volts.
http://www.techsolo.net/download/TP-600_i_e.pdf

Amps x volts = watts
24 x 12 = 288 watts @ 12 volts. The rest of the power supply is dedicated to the 3.3 and 5 volt lines. This is not what is considered to be good as most systems use the 12 volt rails much more.

With older systems those lines had been used, but now the majority of the power comes from the 12 volt rail(s). Some still comes from those rails, but its not too much.

Now if you look at this quality power supply, while only rated at 300 watts it has just as much power on its 12 volt rail as that other 600 watt unit(288 watts). You clearly can not load up the 3.3 and 5 volt rails to the max and still pull full 12 volt power, but systems are not that 3.3/5 volt hungry anyway.


I suggest you see what else you can find.

The power supply is like the heart of the system, you do not want it to fail.
December 11, 2012 12:58:10 PM

the 12 volt rail is the one that has 4 pins and goes in the motherboard close to the cpu right ?
a c 112 U Graphics card
December 11, 2012 1:09:51 PM

The 12 volt rail is any YELLOW wires(on the power supply, not fans, most fans use yellow for speed sensing).
December 11, 2012 1:57:53 PM

oke i dont understand the powersupply thing

before i though if a graphics card says the recommende is 550Watts i will search for an 600-650 watt.

but

if i could get any 600-650 watt psu or above it it will do it work to power my whole system + graphics card right
a c 112 U Graphics card
December 11, 2012 2:08:02 PM

Yes it should. Your system is not overly power hungry. I have never heard of that brand so can not give info on how good or long lasting it is. If it delivers the power it claims, then it should work. Just know that it has more in common with a 300-350 watt power supply then a 600 watt power supply.

The video card makers recommendations are to include this kind of power supply I think. After all the 5770 recommends a 450 watt power supply, but can run on a good 300-350 watt unit.

If you see other power supplies, post it here and we can see how they are. I know that is some parts of the world, the selection is lower so this is just a fact of life.
December 11, 2012 2:15:10 PM

oke sorry im a dutch biy and im only 14 years old and i am doing my best to understand it !

is it like gran turismo 5 is a great game but its only for the playstation 3 . if you want gran turismo 5 you need a ps3

same here if you want the xfx 7770 you need atleas a 550 power suply ?

am i right ?

if you look to the image what i posted will it work white my system + the xfx 7770 double dissipation ?

The TP-600 should work. It is just not a very good power supply. It has enough power, just do not plan any large upgrades with it.

If you can get Antec,XFX,Seasonic,Corsair,OCZ(some will disagree),FSP(some will disagree)/ect they are considered to be quality units.

If not, just take it easy on the power supply(don't try to push mad overclocks). This is not to say the system takes 300+(I would guess it has a hard time pushing 200 watts with the 7770 in it) or more watts. It is just good to not cut things too close.

I know it sounds confusing, you just do not want the power supply to fail or be overloaded as the power supply is the only part of the system that can cause massive failures. Quality is very important.
December 12, 2012 5:16:27 AM

oke firs i though overclocking was easy but not i readed alot and learned about the FSB en the multiplier etc how to get your cpu stable. than i though if i overclock my cpu i dont overclock my 4gb ram now i have the new motherboard new cpu and new 4gb ddr3 mamory 1600MHz

im not planning to overclock.

i gonna try to get an 600w powersupply of more i dont understand that much of the amps etc.

i hope its enough to look at the Watts if my system needs a minimus of 300 watt i will get a 700watt psu.

December 12, 2012 2:32:18 PM

Again remember its all about the quality of the power supply.
December 12, 2012 4:59:21 PM

okay yes i know

but for example

im a guy that dont understand of pc's and i bought a graphics card that requiers 550Watt so im looking for a psu around 600 watts.

than will it work or not

maybe this has been awnseren many times sorry for it !
a c 112 U Graphics card
December 12, 2012 5:48:35 PM

The card requirements are based on a full system + card and normally are run over just in case the power supply is not so good. so yes, in general, you should be ok.

For example. AMD's 5770(takes more power then the 7770) recommends a 450 watt power supply, but I have a system with a 300 watt power supply that has NO problems running it. that system has NEVER taken over 180 and in most games stayed in the 150 ish range at the wall. With efficiency taken into consideration, the DC load is even lower.

but by the same right someone could see this and slap it onto another lower quality 300 watt power supply(one with less power on its 12 volt rail) and blow the power supply and system.
