Modular vs Non-Modular for tight spaces

post #1 of 13
Thread Starter 
Hi all, I am fitting a 240mm (RX240) rad in the floor of my case (Cooler Master 690 II), and space is at a premium. My current PSU (OCZ ZT-750W) is over 7" long plus its modular connections and is not going to allow a 240mm rad to fit in, so I am looking at alternate PSU options. My question is this: when trying to fit a rad (or any object I suppose) close up to the power supply, do the modular connections make the PSU longer and therefore harder to fit, or does a non-modular power supply create too much thickness making it longer (even if it is only at one end, that's all it takes to makes the rad not fit)?

I've got 7" (about 175mm) of space for the PSU plus its cable thickness, but also require about a 750W-850W power supply. So in trying to find a good option that matches my requirements, I am wondering if the cabling of a modular or non-modular psu will take up more of the precious little space I have.

Also any power supply recommendations are welcome as well, just please keep in mind my budget is very tight for one (as I did not anticipate having to replace my PSU).

Thanks!

Silverstone Strider Gold are short units and fully modular

If you can fine one that is they are discontinued for the 750 and 850

Good questions

Your best bet is to have a measure up and see how much space you have for the psu then work out from there which will be best for you, let us know how much free space you have and we may be able to help...

I personally use a CoolerMaster PSU because its not too long and has flat black modular cables so in my case makes it easier to fit

I've got 175mm of space for the PSU plus its cables. (my current one is 175mm plus cables, which won't work of course).

I have been looking at this one:
http://www.canadacomputers.com/product_info.php?cPath=33_441&item_id=057239

It is 160mm long, and is non-modular, just not sure if that 15mm space I have is enough to allow all the cables to fit, hence my original post asking if modular or non-modular PSU cabling styles take up less space. (this one seems to be available in either style).

Also I have been looking more at 850W PSU's as I am upgrading my rig quite a bit (though still on a budget) and want to be able to have enough power for my components plus a little headroom for overclocking. I'll list the main specs in case I'm way off with my estimate:

CPU: FX-8350 (though may pick up that newly announced FX-9590, sounds pretty cool), definitely want to overclock in any case
ASUS M5A99FX Pro R2.0 AM3+ Motherboard
GPU: 7870 Crossfire, also want to overclock them a bit
Drives: 120GB SSD, 1TB HDD, plans to add a second 120GB SSD and raid 0 them in long term, also 1 Bluray optical drive
Water cooling loop with XSPC X20 750 pump/res combo, 2x 240mm rads cooling cpu and gpus
3x 6-8" lengths UV cathodes
7x case fans (including rad fans)

Think that more or less sums it up.

You dont need 850 watts even with two video cards

And newer hardware use less power not more

What wattage do you think would be appropriate then?

-an FX-8350 is 125w before overclocking, which I intend to do, and if I do get an FX-9590, which at stock clock hits 5Ghz, wont be any less power hungry, and quite possibly much more (from what I read rumors say as high as 200W). I'd like to have the headroom to be able to handle that cpu plus overlcocking it.

-a 7870 is 190w (each, so that is 380W for me), and again, this is before any overclocking, which I would like to do as well.

-So I could potentially be looking at 580W plus whatever additional power overclocking the components requires, before even taking into account the cathodes, fans, water pump, hard drive + ssd's, etc, usb devices, etc.

What do you think would be the lowest wattage I would be able to get away with, while ensuring I have enough power for all these components? (I'd normally just get a higher wattage psu and not worry about it, but that is what I did last time and now it doesn't fit unfortunately.

That is why I am looking for the minimum I can get away with for this system: any future upgrade will likely reduce, not increase my power requirements, so as long as I meet this build's needs I should be ok, and power supplies with lower wattage usually means more options for smaller sizes as well, since I only have 175mm for the unit plus its cables.

550 watts is more then enough to cover any system with one video card

Yeah, it is pretty tight in the bottom of that thing:

The non-modular cables usually fit down the far side of the rad though, which helps.

GingerJohn, that is precisely the rad setup that I am doing, with a slim 240 in the top and the rx240 in the bottom in that case... it most certainly is tight but I see your non-modular corsair tx750 seems to fit ok, which is 160mm long from what I can tell- That's certainly encouraging to see smile.gif Did you mount the rad+fans right in the pre-drilled fans mount holes in the floor or did you have to "move" the rad and fans over a bit toward the front of the case in order for it all to fit?
post #10 of 13
I actually ended up shifting the rad backwards a bit, towards the PSU, to allow more space for the USB B connector on my fan controller to fit (you can see it on the second picture, the now replaced horrible beige plug).

There is a little bit of play in the fan mounting holes but not much.
