Yep, and so can my Accelero VM-101. I've ordered the $105 Sapphire HD 7750 (the one with a fan).

Re: Low power GPU for a little gaming?

What is the most powerful non-integrated graphics that you think can be powered by a PicoPSU.... along with a motherboard, a CPU, a hard drive, a fan and a DVD? Good question. I took some AC power consumption readings just now that might answer it. The system consists of an Athlon 64 X2 @ 2.1GHz, 3...

Haswell graphics may be triple the performance of Ivy Bridge graphics. Yeah yeah... I know it isn't here today.....

Temps are acceptable. I let ambient temperature get up to 28° in here, and down to 16-17° in the winter. At 28°, the northbridge is warmer than I'd like: 55° at idle, 68° under load. With a CPU heatsink like that, the CPU temps are never a concern. I'm at 22° right now, and it's never exceeded...

I suppose since I don't have any expansion cards, I could rotate the motherboard so all the cables attach at the left side instead of the bottom.

I'm trying hard to avoid replacing the stock heatsink. Do I need to worry about temps like 81°C?

My northbridge heatsink was held on by thermal epoxy (or maybe it was just superglue, I don't remember) for two years. Well, it fell off in this heat wave we've been having.

I understand the PicoPSU is just a 12V->5V and 12V->3.3V DC/DC converter, and it simply passes 12V through from the AC->DC brick, unconditioned. So I won't get any more 5V and 3.3V capacity, but that's fine. Most of my power draw is from the CPU and graphics card, which is 12V. The only potential pr...
