4870 Power supply

feck · 11 Oct 2008 at 15:30

Hi all,new on here.
I have upgraded from 8800 GTS to 4870 512Mb.My 8800 had a single 8 pin power supply but my 4870 has 2X8 pin power supplies.I have a Y adapter which the 8 pin will fit in the 2nd slot on the new card. I have 3 spare 4 pin molex connectors inside my PC which I assume are spares running from the power supply???Do I just plug the 2 molex plugs in to any of these to provide power?Is this safe to do?
I have a 550 watt supply.Thanks in advance.

i thought the 4870 uses a 6pin + 6pin?

what psu are u using?

u can use a molex connector with the adapter to power it.

The 4870 uses two 6-pin connectors.

projects14a · 11 Oct 2008 at 16:01

Yep, mine has 2 6-pin connectors.

As said

4870 = 2 x 6 Pin

4870 X2 = 1 x 8 Pin, 1 x 6 Pin

Adapter cables work as u said, just plug one end into Molex, other into card.

Claimed! haha

Yep tis safe

though a better option would be

an

Antec quattro 850w (with the boy racer stripes!) AMAZING psu, with plenty of upgrade potential and power!

Sorry,it's the Y adapter that comes with the card..It fits in the card slot fine.Unsure where to put the 2 molex plugs.
Intel core 2 duo E6400 dual core 2.13Ghz
Vista 32
Asus P5NE 650i sli
4Gb (not all seems to be usable though)
22" Fujitsu Siemens

put 2 spare molex plugs in the adaptor and the 8 pins in the gfx card!

By the way why an ati card in a 650 board?

feck · 11 Oct 2008 at 16:16

Why ATI?I'm afraid computers aren't really my thing so may have made bad choice.Had a bit of spare cash basically,and wanted to be ready with a nice PC for Far Cry 2.
4870 went back as damaged in transit.Would you recommend I change for another?(same price though)
Thanks to all who replied,I appreciate iyour time very much.

ConTRo13R · 11 Oct 2008 at 16:19

Another graphics card? or motherboard?

Keep the gfx card you have matey! its awesome! google for benchmarks

As for mobo, keep it in mind for a future upgrade, the nvidia chipset is poo unless you using sli

Wouldn't have a clue how to change mobo.Think it'd frighten me to death to be honest!

You cant see all your memory becuase you're using a 32bit OS

Its really not that difficult, make sure you ground yourself by touching the power supply inside your case and watch some videos on youtube, thats what i did and it helped a lot with building my pc and im only 15!

nothing to it really. only about 7-10 cables on the motherboard. put the cpu, ram , gpu in , thats it.

i can't don't it myself due to because im disabled but i tell my gf what to do so if my gf can do it, anybody can..

Sorry to hijack the thread but I also have a 4870 PSU question. I've just bought the powercolor 1Gb 4870 and need to know if my PSU will handle it. I've got an Enermax EG701AX-VE(W) 24P 600W PSU but it only has 1 6 pin on it. If I get another 6 pin adaptor that's mentioned on here will the PSU be powerful enough to cope?

They're poo even with SLI. I've had ~6 NV chipsets now, and all of them died early or just failed to work. I had one chipset that worked well with SLI - and that was an Intel workstation chipset (not Skulltrail).
