Need a new PSU 4 my CF 4870's but which one?

Seriously. That is ALL I have said all along, my original arguement was that if you had a lot of kit you may as well get a Non Modular since you would use up all the cables on a Modular anyway and then if you had a SFF PC or some uber low consuming PC with little need for THAT many cables (low amount of hardware) that you could chose a modular and pick and chose cables.

I give up!
 
i had to use nearly all the cables from my Modular psu, is u see my hardware in my sig. but i bought the psu because it was a good price , not because its a Modular.

More attacks because someone can't conclude a viable arguement. Yay :D

Tom,

I would prefere it if you would let me my state my opinion without getting drawn into a needless debate. I have read your reasons and I understand your reasons for using a captive cable PSU, hopefully I have managed to get my point across why I think Modular works for me?

I don't have a problem with you but if you keep up with the attitude then I will.

So If I have upset you in any way it was not my intent, I am always pleased to read everyones posts and share my thoughts and I have been posting at OcUK for many years.

I hope you take this is a peace attempt and not provocation. :)
 
Soz to interupt again!

Ive been doing some testing, I'm not so sure its directly a PSU problem more of an overheating one. GPU-Z shows one of my temps getting up to 95c (underload).
Could this be becourse the 2nd card isnt getting enough power therefore overheating?

The cards on their own are fine.

Which ones did you leave unused?

Wayne I'm happy for you to state your opinion as the next person I just think when I called upon you to explain yourself just exactly how the PSU's are life changing as they seem to you you started criticising my system and other things which weren't even relevent to the original argument. Just what exactly has my case preference got to do with anything? ;)

As for my attitude that's here to stay and I will continue to voice my arguments which I can backup just as I have done this time with VIABLE reasons instead of the old

"OOOO you can use less cables" - you assume of course that everyone has a low amount of hardware :rolleyes:

I'm still struggling to see the real reason why a modular PSU is so awesome you've just fluttered about with the same old argument but am prepared to leave it there. I think lowii Ashley has made the right choice so this thread has ran its course.
 
btw regarding modular cables having high resistance over time...I've disconnected/reconnected my cables a gazzillion times with my trusty Thermaltake Toughpower 750w. Had it almost 2 years now....still shows the EXACT same readings on all the plugs as when I bought it. 12.04v idle 12.08v load.

I only like modular because I don't actually use all those cables, and I also find it easier to set up the puter attaching 1 cable at a time.

What a load of BS...

Is it? PSU manufacturers have to be very careful with cable lengths as power de-rates very quickly at low voltage. With the high load currents typically seen with some of these cards any significant resistance could lead to voltage drops. I'm sure the vast majority use quality connectors that make good contact and don't corrode, so its not an issue in actual use. However its always best to avoid unnecessary connectors/adapters with high current.

Tom, I suggest you re-read the thread and follow the conversation between the both of us. You seem to be bending my words a bit, very creative but its not helping. All I said was that as good a PSU as the Corsair TX750 is (it's good we both know this) It's just a pain to work with, what I meant to say was it's a pain to work with for someone who is obsessive about having a neat case and owns a very modern chassis with clean lines and open airflow, not easy or enjoyable to faff around with spare elephant trunks! ;)

I think if you built more systems and used a variety of modern chassis's you would know what I mean.

Correct and that was a mistake on my behalf, I should have enquired about the chassis and how much kit Ashley was using.

Conversly Tom I think maybe you assumed everyone else uses as much hardware as you do! :)

Again I didn't say that, I said that a modular PSU is much easier to work with and lends itself to better airflow, I was talking from my personal experiences and I thought sharing pictures of my chassis would get my point across but no, you just came with "I can see some places to hide cables!"

Tom, I have a good mind to ship a ANTEC P182 and a Corsair TX750w PSU over to yours and let you shove the wires out of sight in a couple of mins! :cool:

i think he believes that modular psus are superior because he is looking at the corsair range of psus and has noticed that the main 2 modular ones, the 520 and the 620 are made by seasonic where as the non modular ones are made by the lower rated brand CWT. hence his logic in assuming modular psus may be made by better OEMs than non modular.

but corsair now have the 1000w which is modular and also made by cwt, so that shows that its not just seasonic that make the modular psus for corsair but cwt also make them.

:confused:

main reasons i got my 620 corsair was because it cost me £60 on sale at a shop and also its made by seasonic which kind of swayed me closer to the decision. (not saying CWT is bad, personal preferences apply here)

Mav that's pretty silly! But I reckon you made that post after I tried to explain better!

Anyone: Would the CORSAIR HX620w be enough to run 2x HD4850's? (or 2x HD4870's) in a normal system with normal amounts of hardware?

If not what is the best guesstimate, thanks! :)

That sounds like a viable argument for that range of PSU 520-620 :)

Seasonic are more well known to average Joe this counts when reading reviews.

M8, take out one card and run the sytem like that for an hour, then do the same with the second card. Keep an eye on temps etc.

Do u know anyone with a PSU tester because it does sound like yours is croaking.

I had the same issue when I upgrade to the HD2900XT using an ANTEC TRIO 550W, it worked ok for a week then started crashing!

I bought the Corsair HX620W and installed that and everything was fixed. Protocal dictates you should test your PSU before you buy a new one. I do reckon its slowly dying but it would be a pain to get a new unit and have the same issue.

PSU tester?

No I don't think that's likely. Its a little counter intuitive, heat comes from power. Less power, less heat. Is the second card blocking the air flow to the first? Do you have a multimeter to check the voltages? Not a northbridge fan blowing on the card or something daft like that? If you swap them round does the same card stay hot, or is it the slot position that gets hot?

Not many people know how to use a Multimeter fornowagain! :)

I don't! :o

But that's why I bought a

PSU TESTER!

2 min job and would avoid situations like Ashley is experiencing.
