Hi Cookiebun
you might want to check out this review at JohnnyGuru: http://www.jonnyguru.com/modules.php?name=NDReviews&op=Story&reid=188 (thanks to Soar for original link)
If it was my money and based on the specs for your daughter's PC I would probably go for this PSU: http://www.scan.co.uk/products/650w-corsair-cmpsu-650txuk-tx-86-eff-sli-crossfire-37db-eps-12v-120mm-quiet-fan-single-rail even though it is only 650 Watts.

If you're willing to wait till Tuesday I'll be checking a 4870x2 with the PSU absic linked. Now, I can't guarantee I'll be able to give any worthwhile info as the card I bought may be damaged ( it was sold as unchecked ).
650W is a little on the low side for this card but it'll work. It'd be best to not overclock to the extreme with it, though. By that I mean 1.5v+ on the CPU and high clocks on RAM and GPU, too.

Yeah, but from what I remember you didn't have to go all that far with voltages ;). Isn't your PSU the HX620? Couldn't find one rated at 625W. Lastly, the 4850x2 is a little less power hungry :P. Though, I suppose with all these HDDs you may reach similar total consumption.
Put it another way, this PSU will be enough no matter what with this card but with heavy overclocks on everything it may end up drawing close to 500W under benchmark load. With gaming, ~400W.
On the other hand, this got me thinking. How exactly reviewers measure power consumption? Is it draw on the socket or PSU output? If it's on the socket then PSU strain would be noticeably lower, actually.
Now I'm confused - absic this is all your fault! ;)
edit:
Ok, I think they measure at the socket, so a 650W PSU is almost twice the power required here. In other words, all you have to worry about is your electricity bill. Even with heavy overclocks the PSU should have at least 200W left over.

Hi thanks for all the help, I am using a Corsair 750 PSU in my new system and i used it to run the system my daughter is getting so I know Corsair 750 is able to run it and would be my first choice but the 750 is a bit out of thier reach price wise but if the 650 is able to run her system with no problems I think I will am edging towards the Corsair.
-
The 650 Watt Corsair should handle your daughter's system without a problem. That's why I went for that one.
Isn't your PSU the HX620?
Yep, my bad should double check the specs it is the HX620: http://www.jonnyguru.com/modules.php?name=NDReviews&op=Story&reid=21
You might also like to check out this thread: http://forum.giga-byte.co.uk/index.php/topic,4028.0.html and follow the link that Jolphil posted there. It makes interesting reading.

Hi your confused, yes they will be using it for games and I also think that they might plug it into thier 37"sony bravia HD tv would that put more of a strain on the 650 I know the 750 will cope as I have done it with ours and yes the graphics are sweet but I was told by the wife tvs are for tv programs.
-
I don't really see how a screen can put any strain on a PC's PSU. I mean, all screens that I've seen had their own power cable. In other words, a PC monitor or TV isn't powered by your PSU.
That's a good thing, too cosidering how much power a 37" TV can consume.
-
no the graphics card should have to work harder because of the higher resolution
-
Not that the eXtreme Power Supply Calculator is the final word but entering the system spec's you supplied I get a recommended PSU size of 616 watts
556 watts minimum. I had to do some guessing as detailed info on the build is lacking in some areas so I figured, CPU at stock speed, 4 DDR2 modules, 2 120mm fans, 1 led 120mm fan and 1 140 mm fan, as the NZXT Lexa S comes stock. 90% CPU TDP, 90% system load, 30% capacitor aging. So I agree with absic. A quality 620-650 watt PSU such as the HX620 would be perfect. I then figured adding two more hard drives and a Blu-ray burner and a HX620 will still handle it. http://www.extreme.outervision.com/psucalculator.jsp

I'm not too sure about this but even if it's like that you're still fine.
The way I understand it, GPU load at lower resolutions may drop because of the CPU not being able to keep up with the GPU. Thus throttling the GPU down ( keep in mind that this depends on the number of frames generated rather than resolution ). At 37" the GPU should run 100% load as the situation will be reversed ( GPU limiting performance ). All in all, the TX650W will still handle that with ease.
-
so really what you are all saying is go for the Corsair 650w ?
-
Well, I can't say what the others are recommending but that is the one I would go for. ;)
-
Yeah. There may be alternatives, maybe even something better but this PSU has been thoroughly tested, is rock solid and has good 5-year warranty. Which basically means that you'll be covered for the entire duration you'll use this PSU as it'd be prudent to replace it after 5 years anyway.
-
Thank all for the good advice we will go for the 650w Corsair and if it doesn't work i will tell her to blame all of you.
regards.
-
Nah, it'd be Corsair's fault then as it'd be a dead PSU so you'd have to RMA it straight away ;)
-
bytheway_r did you test the 4870x2 with the Corsair 650w PSU
-
I would... if the other party didn't send it to a different address. Imagine my surprise when the courier called my cell at 10AM and I learned that my package is over 350km from me.
Hopefully I'll get my hands on it tomorrow :P.
-
The 650 coarsair will handle it fine i have 3 computers in total and i have a 750 drawing crossfired 4870 and the 650 is doing the quad core 3.4 with a 4870 and 8 gigs of ram in a haf 922 case. Running it for a year and a half with no troubles at all thru the upgrades i have done to it.
-
Can't really add anything productive as the card I got isn't working which isn't all that surprising. Anyway, as everyone said, 650W will be more than enough to run your system.
Regarding my 4870x2 - the card's behaving like normal as far as I can tell but it restarts system once and then it boots without display. When starting up:
1. Fan starts and works with different speeds during steps 1-4.
2. Overheat diode lights up for a moment.
3. Power diodes ( 8 and 6 pin ) light up for a moment.
4. Overheat diode blinks 2-3 times.
5. System restarts after ~2-3 seconds.
6. Repeat 1-4.
7. System boots ( post beep ) and seems to work without display.
8. After steps 1-4 fan keeps working at some low RPM speed ( silent ).
When I cleared CMOS POST failure window appeared on the screen asking to choose one of previous bios configs. There were 2 or 3 green, vertical stripes on the screen ( from top to bottom ). Other than this I couldn't get the card to display anything.
When I disconnected the power cables fan worked at high RPM and both power diodes lit up and stayed ( which is normal behaviour as far as I know ).
I don't know if it's possible to run it with another card as main? I tried sticking in both this and my 4870 512MB and it didn't work, no display.
Any ideas?
-

I don't think that the 650W PSU would be enough to power both those GPUs at once so that doesn't really help a lot. :-\
Have you checked to make sure that the power cables to the GPU are the correct way round. There was a member the other day who had the connector wired up incorrectly as far as we could tell.
-
It'd be if it had to. I have some parts meant for a 2nd PC around and there's that 500W OCZ PSU in there. I suppose I'd need the crossfire bridge for it, though?

I don't really see how it'd matter with these power cables? I mean, on this PSU there are 2 PCI-E power cables, both 6+2 pin.
-
We are still looking into the cable problem but the colours didn't match what they should have as far as we could tell.
Do your graphics cards only use one connector each?
-
4870 512MB uses 2x 6 pin and 4870x2 uses 8 pin and 6 pin. That's why I wouldn't even try with a single PSU as I don't have enough connectors :P.
-
It would be quite possible to set one up as slave to the main one used for powering the system and just run the extra GPU off it for trial purposes.
-
Yeah but that'll take a while ;D. Just ordered a crossfire bridge as I don't have one. Should get it next week.
-
It should be possible to run them both as two standalone cards on the one system with a monitor connected to each.
-
Don't have a 2nd monitor :P. I think I'll wait for that crossfire bridge. It's not like I'm in a hurry atm.
You know, it's crazy what kind of info there is on the net. People seem to have the weirdest problems with their hardware and the solutions are even more bizzare :o.
-
Yes as you say there are some crazy situations out there and some even crazier fixes. :o
-
I checked it with different RAM, CPU and MB to rule out some stuff. With 2x6 pin connected it started beeping and showed that it requires more power on the screen. I think it's toast, though as it had grey artifacts all over the screen. Technically, not all RAM chips are covered properly by thermal pads but I'm not sure it'd matter this much ( especially during bios )? By that I mean that 2-3 weren't covered fully with one being only about halfway covered.
-
I take it from your reply that you have removed the casing. This will invalidate the warranty. These chips can heat up quite quickly but I don't think any damage would have been done yet.
-
Yeah and I wasn't the first person to do so. As I said, I bought this card knowing that it could be faulty. There's also no warranty to talk about. Oh well, I'll most likely sell it once I play with it a little more. I have to say it was fun taking it apart ;D.
-
LOL i know been there and done that. Trashed more systems than i care to admit and then fought them to find the workaround but Vista game me the most trouble glad i went to 7 ultimate.
-
Hi power supply up and running haven't tried it with a game yet but it boots up and looks as if everything is running ok.
-
A good power supply makes all the difference in the world. 8)
-
See, I told you it would work!
-
I never doubted you honest. regards
