Hi all,

Apologies if this kind of query has already been answered - I did a quick search, but couldn't find anything.

Are there any solutions to using a nice fanless Streacom case when a > 200W PSU is required?

My system is already built, so I'm looking to replace as few components as possible. I fear that I may have too much power consumption to make one of the nice Streacom fanless cases a possibility.

My system:
    Gigabyte H77N-Wifi motherboard
    Intel i5-3570K CPU
    TSB 6922 DVB-S2 satellite tuner card
    SSD
    SATA HDD
    BlueRay drive
    2x 4GiB RAM
    200W PSU

I gather power supply might be an issue as these cases only accept a PicoPSU supply, and the maximum power output of one of those is 160W. Would it be possible to buy and use a Streacom case with a PW-200-M PSU?

Any insight would be most gratefully received. I don't really fancy spending a few hundred pounds on a new case and PSU that will then melt my system!

Welcome to SPCR!
SPCR tested the Gigabyte H77N-Wifi drawing 114W from the wall with a PSU efficiency between 80% and 82% comes to 92W give ot take 1W. DVB tuner uses maybe 15W the HDD 10W and the optical drive another 10W. That comes to 130W peak load. Typical load probably in the 40W-65W range. Without a discrete graphics card a Pico PSU will do fine.
The PW-200-M PSU is very similar to a Pico PSU in that it plugs in directly to the 24-pin power header of the mainboard. Unlike the Pico PSU the PCB will be parallel to the mainboard and not extending upward. You'll need around 4cm next to the power connector or an extension cable for the power connector. A cable might be a good idea because a Pico PSU might get in the way of the heatpipes used in Streacom cases going from the CPU socket to the right.
A streacom case is great for a HTPC, when you have a passively cooled system you might want to do something about the hard drive noise. If you plan for that you might want a larger case just to be prepared to add a hard drive suspension.

Wow, thanks for a really detailed and helpful reply!

That's quite reassuring. If 160W will cover my usage, then I'll forego the PW-200-M and get a Pico instead. Now, if only I could make my projector silent too...

Streacom themselves keep saying they are going to launch a 250W fanless PSU for their systems yet there has been no release, no pictures, no specs, no preview. The name I have seen mentioned is 'ZeroFlex'.

I really hope one of these comes out and then I really would want a Streacom for everything.

Hello,

the name for our fanless 250 Watt power supply in Flex format is called StreaFlex 250. We showed a working sample at Computex this year and we are currently finalizing it for production as well as Nano 180. They will both be available within the next 2 months. StreaFlex 250 is mainly being developed for our upcoming DB4 case, which will be ready in Q1 2014, hence small changes on the design of StreaFlex 250 and the reason for the latest delay. StreaFlex 250 was already mentioned last year, that is right, but rather than releasing a product that is not as perfect as it could possibly be in our eyes, we started from scratch. The StreaFlex 250 PSU will fit into FC9, FC10 and DB4.

BR,
Oliver

250W passive in a small form factor is cool.
A current system without a discrete graphics card will draw about half that power.
Does the PSU come with a 6-pin PCIe power connector so all that extra power can go to use?
Will you make a pssive graphics card cooler for your case(s) to build a passive gaming system like this impressive diy system?

Hi boost,

yes StreaFlex 250 will come with a 6-pin PCIe connector. 250W is about the limit for a passive solution of modern PSU technology for a small form factor such as FlexATX.

Highfi's DIY FC5 is indeed impressive. Being a Gamer since age 4, let me assure you, being able to build a silent gaming system based on Streacom products is high up in my personal priority list. However, there are too many different VGA card layouts regarding GPU and VRMs, so building a universal solution is not an easy task and having a very limited solution would not be satisfactorily for anyone. This is not an official announcement, but the chances are high, that we will have a product featuring a silent VGA card solution next year. We have many different ideas to make it happen, fingers crossed any of them will stand the test of the real world.

BR,
Oliver

Thanks for the info Oliver. The ZeroFlex name is just what I'd seen at bit-tech.net: http://www.bit-tech.net/news/hardware/2 ... eacom-db4/

StreaFlex I know you were touting before as a name which is partly why I was confused. Was ZeroFlex ever a name you were going to use? I see you describe it as FlexATX form factor. Does this mean it will be a 81.5x40.5x150mm internal PSU without a need for a power brick? This would be very exciting not just for your cases but also for custom built silent SFF systems and it could be fitted into 1U systems or Shuttle XPCs.

Very exciting. I'm yet to see the final DB4 but a 250W passive PSU and a mid range graphics card undervolted would be a great combination with it I think. My next computer perhaps.

Hello edh,

yes, we had some discussions on whether we should use StreaFlex or ZeroFlex and decided for StreaFlex in the end. Not entirely sure if it is the final name, but there is a high chance it is. Either way ZeroFlex and StreaFlex are the same product in case that caused some confusion :)

Dimensions for StreaFlex250 with the "heat shield/heatsink" are 139 x 45.3 x 86.5 mm and all you need is to plug the power cord into the PSU. As for custom designed SFF cases, the right amount of cooling depending on the load have to be kept in mind. StreaFlex is designed to make use of the "unused" side of FC5, FC9, FC10 and DB4 for cooling. In a closed case, there have to be some openings to let the warm air out/colder air in. I can tell you more about this once I have the final version for thermal testing.

Oliver

Edit: I just have been told the final name is still in discussion, so it could also be ZeroFlex. My apologies for the confusion >_<

This all sounds great! I appreciate that you may not be able to say everything until it is finalised and then I look forward to the reviews.

I'm really excited about the fanless PSU and the DB4 chassis. I wouldn't mind the 95 TDP Kaveri APU and completely skip on any additional GPU. The perfect HTPC and/or entry gaming solution. Kaveri APU does 28-50 fraps in BF4 so it's powerful enough. Cooling the VRMs with a 95 TDP processor might be a challenge in a passive case such at the DB4, to which hopefully Streacom has/finds a solution.
