Need more power! Antec ISK 310-150 Build PSU Help

[SpeedEnforcedByAircraft]

Hello, everyone! I'm looking to cram a Dual Graphics setup into a tiny Antec ISK 310-150 case. I've confirmed that the parts I want to use will fit inside the case(with two high pressure 80mm fans for heat dissipation), but I'm having a power problem.

There's my build. The problem is, I need 250 watts instead of 150. How can I swap the included power supply for a different one, or perhaps I can supplement it with a picoPSU for CPU power? It sorta looks like a FlexATX PSU, too. How should I go about doing this?

Now, I can hear you all saying "Why not a Fractal Design 304 or a Silverstone Sugo SG13 or something similar?" I want the smallest case, and here it is. Please help me shove a Steambox in here.

I've never worked in that case, so can;t confirm if you can switch out the PSU - I would expect it to be SFX, so you should be able to.

You also want more than 250W, to ensure you're not running at 100% load on the PSU (or near 100% anyway).

What about this pairing:
PCPartPicker part list / Price breakdown by merchant

Case: Silverstone RVZ02B HTPC Case ($64.99 @ SuperBiiz)
Power Supply: SeaSonic 350W 80+ Certified SFX Power Supply ($41.99 @ Newegg)
Total: $106.98
Prices include shipping, taxes, and discounts when available

By the time you replace the 'included' PSU, you'll be north of $100 anyway, and this would just get the job done from the outset....
Nicer case too IMO.

Yes, but 250w continuous will be perfectly fine.
The RVZ02 is junk. Feels flimsy, and is as big as two of these cases side by side. I replaced it with the Node 202, but found that it still didn't satisfy my urge for smaller computing, especially considering I'm using low power parts compared to stronger CPUs and GPUs.

We'll agree to disagree on the PSU aspect.

Looking at the images here: http://store.antec.com/isk-series/isk-310-150.html (under the "Power Supply" heading), that looks proprietary to me, I wouldn't imagine it could be replaced (at least not easily).

As for supplementing it, I won't recommend that. It might work in theory, but doesn't sound like a smart long-term solution.

I thought so too. trying to figure out the width dimension of the case. If I remove the proprietary one, do you think a Flex ATX PSU would fit there?

 

[Barty1884]

Looks like the closest match anyway......at least on dimensions alone. Looks proprietary connections etc though, so won't be easy (assuming it's possible to begin with).

Eh... I'll just attach the PSU to the floor with double-sided tape. The bottom comes off, revealing four screws to remove the power supply. Can you help me find the military.

 

[Barty1884]

Does it come out that easy? Looks like it's on a hinge similar to old Dell's etc.... from the one image I can find. Different if you've got the case in front of you.

How does the PSU attach to the case to use the power cable on the rear of the case? Assuming it's not a proprietary connection on the back of the PSU, then it should be a pretty simple switch out. If it is, you got some re-wiring to do, or find another way to route the power cable?

 

[Barty1884]

Looks like a standard extension cable, so hopefully it's easy enough
