What PSU to use for 2, 3870x2's

[domy85]

Ok Im looking for a psu with 2 pci-e 8pin connectors and 2 pci-e 6 pin connectors because i am upgrading from my 8800 ultra to 2 3870x2 with EK water blocks. I looked everywhere and cant find one. Do the optional molex to 8 pin connectors work for pci-e or is that just the mobo connection? Im not looking to spend over $250, any help would be great cause im ready to purchase but not sure about this psu, thanks!!!!

System:
Asus maximus forumla SE
Intel Core 2 Extreme qx9650 @ 4ghz
4GB mushkin xp2-9200 @ 1150mhz
Thermaltake 700watt psu
1/2" swiftech water cooled system w/external radiator

i second this psu, cant go wrong with pcpower&cooling

[domy85]

i agree, but it doesnt have 2 8pin pci-e connectors i need :)

[rangerone766]

yes it does

i know it has atleast 1 from newwegs pic, its a 6+2. give me a few minutes with a flashlight. i have that exact psu in my rig.

PCI-E Connectors 2 x 6Pin, 2 x 6+2Pin ;)

PCI-E Connectors 2 x 6Pin, 2 x 6+2Pin ;)

thanks, i would have had to pull out a drive bay and side panel to get at mine. i have the wires tucked out of the way.

[domy85]

oh it has 2, pictures can be decieving :D

750 watts enough for my setup? look at first post for specs then add in 2 3870x2's

Full load in world in conflict with max settings on my 8800 ultra pulls 470watts

[rangerone766]

check my system specs fairly close to yours. i did manage to borrow a friends pair of 2900pro's that i flashed to xt's for him. ran them for the weekend and never had any problems.

[domy85]

True, i think i would be safe. By the way, i built a 700 dollar system for a extra pc on a dvi kvm that i do other stuff on i wont do on my 64bit gaming rig. I got a 2900gt and 2 days later they discontinue them, cant even overclock the card, but it was a budget system so i hope it wont have problems :banghead:


Ouch i just dropped $1350

System complete for years to come :P atleast thats what i always tell myself lol

Here is the official certified list:

http://game.amd.com/us-en/crossfirex_components.aspx?p=3

A quality PSU of 670W or better should do the trick if the amperage is decent enough. I have a Thermaltake Toughpower 850WW0131RU (850W) that is on the list.

Careful with ur wording there. It is cheaper but better, NO.

I have a few of the PC Power & Cooling PSs and they are very good. And the 750 will power his comp. But it is capable of 60 Amps on the 12V rail. The Silverstone can get up to 80A(88peak).

THE 750W ONE OBVIOUSLY

another good one :)

[panchoman]

PP&C 1kw. great performance price and efficency. and each psu (all pp&c's) is indivually tested for durability, stability, and longevity. on top of that, 1kw psu purchases will get you the exact psu test report for your indivual psu with the purchase. so you can be assured that the psu is going to serve you faithfully. on top of that, you cant go wrong with a 7 year warranty.

Was gonna recommend that too :) one of the best power supplys ever made. :rockout:

[domy85]

Wait so that list was for only one card???? please tell me it was for 2, the psu itself does say quad which is for 2 cards correct? how much power does exactly one of these cards draw?


my pc right now with my thermaltake 700 watt psu and nvidia MSI 8800 ultra OC idles at 290watts

[flashstar]

http://www.zipzoomfly.com/jsp/ProductDetail.jsp?ProductCode=10005493

This is the best psu every made! :rockout:

The Real Power Pro 750 watt model is $67 after rebate with free shipping:

The PC Power PS is VERY good. But something to remember is NO PS rating is perfect, on every PS power is going to be wasted (changed to heat). If you are going to build an EXTREME comp dont pust the limits of your PS. The 1000 watt one will push power to all ur stuff with less struggle, and if you OC dont forget that raises the requirements even more.

Better safe than sorry.

[domy85]

MK with your experience will the amperage be enough for my setup and those 2 cards? the wattage i wouldnt be worried about correct?

[ShadowFold]

Get the PCP&C 750w, or 1kw if you want overkill.

[domy85]

ok good cause i ordered the pc and power cooling 750 quad crossfire edition and my 2 3870x2's and my 2 ek water blocks :P

[ShadowFold]

Man you are lucky :D good luck overclocking them! I know from experiance the HD 3000's oc like beasts!

[panchoman]

good psu choice, and dont forgot to tell us how to goes!

[MKmods]

MK with your experience will the amperage be enough for my setup and those 2 cards? the wattage i wouldnt be worried about correct?

It will work, PC Power and Cooling PSs are built to deliver more than the rated power. Amps, Watts and Volts all matter, as well as the input (AC power from the wall)

I just would rather have a bit more just to be safe. Especially if I was spending as much as you, (although I can be a bit of a cheapskate, lol)

[domy85]

i will definetly post my scores :cool: Thanks for everyones help so much, if it wasnt for everyone, i wouldnt of gotten a quality psu :) and prob the wrong one lol

[philbrown23]

I would go with the silverstone ;)

[panchoman]

little too late phil :p

lol, I love the people on this forum. You guys ROCK!

[panchoman]

apevia's are actually preety good if that was supposed to be sarcastic :p

[flashstar]

People are just too close-minded here sometimes. The Cooler Master 1000watt and 750watt psu's have gotten near 10/10 ratings from every review site. I can also guarantee that the quality is outstanding and even bests my Fortron Source Blue Storm. I can't imagine shelling out $100 more for a PCP&C psu which is the same quality...

The Cooler Master is even on the "bad" psu list here! :laugh:

[panchoman]

seasonic kicks the crap outta any other oem.. including the many different and weird ones that make up the cooler master psus.

[flashstar]

Pancho, you get me proof and I'll reconsider my statement. :banghead:

[panchoman]

Pancho, you get me proof and I'll reconsider my statement. :banghead:

cooler master 430w's are made by hipro... you know how notorious hipro's are..

as for seasonics.. show me a bad psu from pp&c or seasonic (both of which are made completely by seasonic)

[flashstar]

I'm referring to the 750 watt real power pro. I've never dealt with the 430 watt models, but I agree that they're probably cheap. Fortron Source and Seasonic both have cheap models. I've you're interested in a high-end computer you get a high-end psu, so the low models should be off your list anyway.

My 750 watter is simply amazing--and inexpensive!:cool:

[freaksavior]

when you get your setup finished, come post your score in my 3xxx thread. its in my sig

btw, Ultra X3 makes a 1600w psu ;)

edit 2: They also are making a 2kw psu :eek:

[Spacegoast]

i like the PC P&C psu's but i dont think the Silencer 750 ( i have one :D) would be enough. There is a new one which is 860w that just came out and received a very good rating in CPU magazine. Here is the the link:
http://www.newegg.com/Product/Product.aspx?Item=N82E16817703013
i would also recommend the Silverstone OP1000 as MKmods suggested or the SilverstoneDA850 as those too are excellent psu's. The Enermax Galaxy 1000w psu is also nice if you can find a good deal.

It sure does. 2x6 and 2x6+2. As long as you get the crossfire one it will.

My HDD light would not even blink with one of those

[domy85]

This thing will save alot of hassle, I should know I have it.

http://www.frozencpu.com/products/5953/bus-102/Zalman_ZM-MFC_Multi_Fan_Controller_-_PWM_Fan_Ready.html

Monitoring how much wattage your pc is pulling from your psu is like a dream come true. Its a good thing i can watch this when i get my new cards lol.

-praying i have a little wattage left over from 2 3870x2's on a pc and powercooling 750 quad ready-

I probably should of went with more but then i would have to cancel the order, wait days on days for the money to come back to me which has already been taken, yata yata yata, so ill take my chances :D but from hearing on others opinions it will be fine, i have a right to panic!!! :)

Wow very nice, i bought mine awhile ago, i dont remember if newegg had it at the time or not.

[Deathshead]

sorry i posted this in the wrong thread, ha! im retarded

[t_ski]

I think that list is for 1 of the X2s

I suppose you could be right, but I think there's enough headroom on my PSU to handle a second card. I'll let you know as soon as I can afford one ;)
