Corsair 620 enough for a Mega Rig? + 1kw PSU for UK households

If this is in the wrong section then i sorry :( , i just figured that psus would fit in the cases section

Heres the Dealio..

Ive specced up my next system entirely, and now im trying to shave off a hundred pounds or so. 40 pounds i could lose directly from downgrading the psu i had hoped for from a bfg 800 watt to the corsair 620hx, Whilst Ive heard that the corsair 'will' power a next gen Sli system i have my doubts, i was wondering if i could get some informed opinions on the matter, please remember im trying to cut money off the total not add it on, so please dont suggest me a 1kw psu even though i know that would be the 'best' option, and yes i have used the psu calculator but i thought its result may have been slightly off as most the Ampage is something that will hold the sli rig together.

heres my new pc spec;

c2d 6600 = hoping to overclock as high as i can >3.5 - but also with a quad core in mind for near future upgrade.

2gb highly oC'd 6400 ram, again i would like to leave it open for 4 gb

680i platform

2 x 8800gtx - moderate overclocks - again leaving it open to whatever 8*** models arise in the near future

12 x 12cm case fans - yes 12

3 x 500gb hdds, plus 1 x 80, 1 x 250 and leaving it open for a scsi/raptor

2 individual watercooling set ups with 120.2 rad and a pump to each.

2 x dvd rw drives leaving open to a (wheneverthis happens; sub 250 pound blu ray/hddvd writer)

4 x 120mm ccfl tubes

2 sets of EL wire

then 1 fan controller bay , external USB hub, led keyboard, and IMon VOF lcd that comes optional with thermaltake Tx

and yes i am serious about the spec. Im just waiting to hear the "dont buy 2 8800s if ** shaving money and so on", the spec is the spec :D, thats how its going down, Any advice on my choice of PSU is greatly appreciated, thanks in advance

Firstly I have to say, WHY 12 FANS???

4 for the two rads, 3 for the case max, that makes 7, WHY 12???

Anyway, the psu issue, 620W does sound a bit low for what you intend and your future upgradeablity.

Here is what I would propose you do.

- You only need two ccfl's so get rid of two of them.
- Why do you need two watercooling setups?. Just get one good one.
- Cut the number of fans back to at most 7, if you have 12 it will be like a wind tunnel with crap airflow.
- You seriously can't need that many hdd's

Now you can afford a better psu.

The rest sounds great.

I would say yes tha Corsair would be enough to power that rig. I would wait until someone confirms that though. The question that jumps to my mind though is; Why 12 fans? That surely is overkill and won't do anything good for cooling.

Quad core and 8800GTX SLi... no chance :( You need at least a 700w Seasonic or better.

But yeah... 12 fans?! no point
 
Forgot to say im using a thermaltake TX, i may not need that amount of hd space but i currently have the Hds and keep them about 70%, 2 watercooling loops (1 to start with) 1 for the processor and 2nd proc on mATX (a month or so after the initial build), mobo components, and 1 loop eventually for the SLi dx10 components and whatever 3rd card gets thrown in there. Yes 12 fans - 1 infront of the hd cage, 3 infront of the mobo and one to the rear, 4 on the dual radiators, 1 for the micro ATX system and 1 more to actively cool the ram.
 
Hmmm.

My PC Power & Cooling 750 watt Silencer (with a 60 amp Single 12v Rail) was just about upto the following:

x6800 Extreme (non-oCd)
8800gtx SLI
4gb DDR2 (Corsair 6400c3)
3x 74gb Raptors
3x 120mm Case fans
2x DVD RW Drives
Soundblaster X-fi

However, with Oblivion in full swing, I could just sense the tension it was under, fan was right up to max speed - may have been due to the limited clearance above it in my Akasa Eclipse, nevertheless, I didn't feel at
ease.

Your initial setup is slightly less demanding in terms of CPU, 2gb RAM vs 4 and hard drives with lower power consumption etc....BUT....you say you'll want to leave scope for upgrades (such as quad core and raptors and 4gb RAM :eek: ) and then there's the small issue of your 12 fans and water cooling apparatus.

In short, just get an Enermax Galaxy 1000, I know it's another 100 odd, but it will offer you a supremely stable foundation for years to come, it's also much quieter than most, if not all other units of equivalent wattage.

That Corsair will most likely struggle from the day one, and the moment you start squeezing in those upgrades...it may well throw a wobbler ;) .
 
:D Thanks for the input, so looking at the 1kw range... Im finding it hard to come by any reviews for the bfg 1000 and the Tagan is also sparse. I know the Galaxy 'is' pretty much the be all and end all at the time being but does the bfg 1000 compare and equal or match its standards. Sorry to keep this going but again, i like to keep my prices down. And if im told the BFG 1000 wont guarrentee me peace of mind then ill go with the galaxy.

(Heh looks like ill be ordering some cheapy 8800s :( )
 
I doubt the BFG would match the Enermax in terms of build/component quality, despite it's claim of "lifetime" warranty. As you say, reviews are pretty scarce - perhaps non-exsistent as yet. I've never been one to "pay for the name"...well...in every instance ;) , but it's quite difficult for one to ignore Enermax's reputation in this particular field.

However, if that £40+ means so much to you, I'm sure it too would fulfil your needs though it may be a little more noisy under stress - can't see if it has a large fan underneath.

I can't help thinking with all this quad/dual hullabaloo why are you trying to save £40 on the thing that could kill the lot?

Awesome spec by the way, I planned to put 2 systems in 1 case once.. you must do a project log if you actually do it.
 
in terms of PSU, if you're spending that amount of money I would no further than a top of the range Seasonic or Tagan PSU...
 
3 claps for the OcUK community, in under 2 hours ive decided to spend more than double on the item :D hahaha, I figure that if i get the galaxy it is going to be a keeper... :D

One thing though... I personally dont know a great deal about electrics, but when i jokingly mentioned to my step dad (joiner, not electrician, but well educated) that I might be getting a 1000w psu he said that the house would power it... hmmm, i laughed for a while but then remembered i know very little about electricity (other than what i need to). Is there any truth behind this... as ive never gone near that amount of power, or at least i dont believe i have..

Looks like ill be upping the amount of money I put toward the electricity bill :(

Thanks for your help guys

Just had a word with him and he said we had a 16 amp breaker, hmm
im thoroughly confused, But then again i know nothing about electrics in the house

that is going to have a noticeable effect on your electricity bill if its under load often, my phase changed sli system did.

To be honest when its idling you can set your pc up to run very light on power, I do remember seeing something in custom pc last month about this.. in fact.. here on top of my pc lo.

QUOTE-Custom PC

"I recently spoke to scott herkelman, one of the founders of BFG who suggested that a top end G80 sli rig would suck so much juice from the wall that it would trip the power switch in many uk households, particularly in houses that were more than 20 years old (matt100-thats me out then lol), this is speculation of course but we won't have to wait long to find out"

Hmm.. interesting, seriously now, don't skimp on that psu.

You might want to invest in some sort of mega high end ups unit too :)

Well, you either spend the money on protecting an ultra-high-end setup, or you take the spec down a peg or two to avoid going over budget. Those are the only two options with any kind of safety margin :)
 
no, thats a surge protector.. I mean something like this

http://www.overclockers.co.uk/showproduct.php?prodid=UP-015-BE

you switch your pc on, the switch it tripped but this thing keeps your pc going via a battery so you can shut it down properly.

I've never bothered with them but then I've never had a pc that could trip my switch even with an x2 4400 and sli'ed 7800gtxs there was never talk like this.

your buying an awesome system, get the best psu and that surge protector - its just not worth it going pop now is it! - after doing some sums i don't believe a 1kw could trip a uk household in MOST circumstances - but obviously this isn't taking into considering you might possibly have more than one high drain appliances in your home. (eg you have 2 electric cookers, not one) etc etc. im fairly confident it should be okay anyhow, if you do notice you loose the house fuse within a few weeks of using the system then id say get a higher ampage double pole fuse for your house :D done the trick at me mates lan party hehe

HAHAHA, damn....

So really, I started the thread to find out if a 100 psu would do the job...

and now 300 is more of a realistic figure, hmmm

Ive always told myself that for certain components I would never pay more than I allocated before speccing the build.. E.g

Case - 120 pounds MAX - Spent 150

GPU - 350 MAX - still achievable

CPU - 200 pounds MAX - thereabouts

system water cooling - 250 - spent 150 for the first loop of two + g80 waterblocks

Mobo - 150 - spending over 200

PSU - 120 - (undecided but upwards of 200)

At the end of the day, computing is among the most important things to me, and im willing to pay the premium to drive around in my ferrari. I dare say a few days from now (advice pending) I will shell out for the top end PSU, but only if I know for a fact that my breaker wont give in the second i put my foot down.

Advice from anyone with a g80 sli + quad core + similar set up is appreciated, eg. do you have a USP in placeand has anyone ever overloaded their breaker with pc equipment
