Hi, right I've measured the distance between the rear panel and the central divider and it is 242mm. I'd think, though, it would be possible to remove the divider if required...

hi

i think the latest PSU's 1000 watt and over are 220mm long, so the PSU would fit BUT the wires behind it would be a tight fit so i guess the divider would have to come out

OK thanks for the measurements ChrisC

Hi, or purchase two 500 watt PSU's and save the hassle...

lol

there's always that option i guess

the only thing that concerns me about that is cooling 2 PSU's that close together (double the heat to disperse and no where for it to go)

You can just turn the PSU mounting around so that the fan can point inwards.

How? The four standard mounting holes for psus are not square so its impossible.

Lower efficiency, more heat, can cause stability issues.

cuke2u · 3 Dec 2006 at 21:17

Hi, errrr, look at the holes for the mounting plate, not the PSU ones. Isn't that what the case is made for? Plus it will be cheaper, have more power and, as you could choose a PSU with less fans, quieter amd more heat efficient...

Would someone be able to tell me how easy it is to remove the grill infront of the front fan and behind the rear fan? Are they riveted on or screwed on?

Does this case have dust filters, and if so on which fans?

Thanks

The entire psu mounting plate if turned upside down wouldn't be allowing the psu fan to face inwards, and you can't turn the psu around because the holes are not in a square shape, so if you have one psu you cannot face it inwards for better airflow.

I've been having a think about dual psus, i said earlier it would be less efficient than one higher power one but i think i'm wrong, efficiency and therefore heat generated would be the same. Therefore two lower power psus will be better than 1 higher power psu as it will be quieter, larger area in which to dissipate heat, two slower fans rather than one faster one etc.
My only concern is would you get stability issues? And you would probably need to be careful which psu is connected to what and how they share the load.

hi

i am not saying your wrong about 2 PSU'S being better than one as i am not sure myself, my thoughts are 2 psu's double the fans (more noise ) one 1000 watt psu will have bigger fans which can turn slower to move the heat (bigger the fan the slower it has to turn to move the same heat as a smaller fan ) also with two psu's that close together theres less room for air circulation so that has to generate heat, as for how to connect 2 psu's i guess one would have to be connected to the motherboard and the other would have to run harddrives,fans and cd dvd drives

Well this is what i thought at first, bit i think its wrong.

Firstly, most psus use 120mm fans now so i'm assuming two 500w psus using 120mm fans vs one 1kw psu using a 120mm fan and a 80mm fan.

The same amount of heat will be created with either two 500w psus or one 1kw, but with two 500s you have two 120mm fans to remove it whereas with 1 1kw you only have 1 120mm and one 80mm, so the two 500s will be quieter and will give more airflow.
You also have almost twice the surface area in which to dissipate the heat.
Overall this means slower quieter 120mm fans. You can't get a 1kw psu thats even quiet, but you can get 500w psus that are almost silent.
I don't believe two 500w psus will be any louder than one.

Of course a lot of 1kw psus use just one 120mm fan which would have to create twice the airflow of each 500w psu so that would be much worse, or even worse some use two 80mm fans and theres a reason they look like 3 bladed props.

cuke2u · 5 Dec 2006 at 09:15

Hi, agreed Joe42, plus two PSU's would have greater output than one 1kw PSU. If they were sharing the load between them then they'd be less stressed thus also greating less heat and noise.

Coming back to the PSU mounting, all I can say mine is mounted with the power switch nearest the centre line of the case, with the power socket close to the side panel. Also the modular connectors are nearest to the side panel. If you look at the pictures here, and they have the PSU the correct way up then any fan on the base of the PSU would be facing inwards http://www.antec.com/us/productDetails.php?ProdID=28550 and see if you think I'm correct...

Joe42 · 5 Dec 2006 at 17:26

I'm talking about 120mm fan psus here where the fan will face towards the side panel, standard 80mm fan psus are fine. Sorry for any confusion.

cuke2u · 5 Dec 2006 at 20:23

Hi, again, you mean fans in a normally mounted PSU that would face down? That's what I'm on about...

Nope.

I mean with a 120mm fan psu the fans face outwards and when using only one unfortunately you can't flip it around so the fan on the bottom faces inwards.

crazyswede · 5 Dec 2006 at 22:20

If you use any of the 2 psu slots normally or both at the same time then the fan will point outwards towards the case sides with about 1cm gap for air. But you can flip it vertically and have one psu fan facing inwards. But to do this you need to bend one small bit of aluminium very slightly (I think). I have not done this yet, but I am going to try it, maybe tonight.

Could do with some answers to these questions if anyone knows.

cuke2u · 6 Dec 2006 at 10:08

Hi, well as I've stated before, if my PSU had a second fan mounted on the bottom it would face inwards, as the all of the pictures I think have demonstrated. If you want to believe they won't that's up to you but mine would and without bending anything.

As fare as the fan grills are concerned, I know that the rear fan one is screwed on. I have to take my side panel off again tonight to sort out the sound, I'll let you know for sure on both fans then...

I think you are wrong

Please don't be angry :eek:

The case has been designed so that the side fan on a psu (which is sort of designed to suck air from the cpu heatsink area) points outwards. My psu has a side fan which is in the same position as all other psu fans that are on the side and there IS NO WAY you can make it point inwards without flipping the backing plate upwards. I sat there when I got it and tried all the combinations possible... but I could have course be wrong.... I will try tonight and take some pictures. My aim is to have it pointing inwards

cuke2u · 6 Dec 2006 at 11:21

Ok crazyswede,go for it, not angy at all. Maybe I just fitted my psu mount the way it is by accident, and the pictures don't lie as the power switch, power cables and the modular cabling all point to my PSU lying on it's left, which, on a normal PSU, I would have thought, have the bottom fan pointing inwards.
It's all a bit academic anyways, because if you purchase a decent enough efficient PSU, it will probably only have one fan.
Still I'll check again this evening...

Joe42 · 6 Dec 2006 at 12:11

The reason for the confusion here is that 80mm fan psus such as chriscatt's have the pcb on the bottom and 120mm fan psus have theirs on the top.

If yours was a 120mm fan psu the pcb would be on the inside edge rather than the outside and the fan would face outwards.

Glad to hear the rear grill is screwed in, if you could have a quick look at the front one to see if its the same next time you have it open that would be fantastic.

What about dust filters, does it have any?
