88% Efficient CoolerMaster 900W

80 PLUS Silver - first high watt PSU ever to get this. (There are 4 total, the other ones are 200-300 watters.)

List of 80 PLUS certified PSUs. Nice site for looking up appropriate PSUs for the build you are making. Typically the PSU will be more efficient at 50% load than 25% - so there is such a thing as having too powerful a PSU (if you want to maximize efficiency that is).

small switchmode regulators can do 95%+ so there is still room for improvement. nice to see none the less

I'm more interested in the NXP 270 Watt unit, but I can't find it for retail sale if it's available at all (and for 230V). If you'd be interested in energy consumption you wouldn't build a 900W PC in the first place (I can't even begin to think what kind of ludicrous piece of pc needs 900W!)

SLI, Tri-SLI, 4xGPU SLI (dual GX2's), Crossfire, Quad-Crossfire...

Skulltrail (2x Quadcore).

Well servers that can take 2 Xeons, 6 drives, RAID card, FBDIMMs generally come with 700-1100W PSUs. Consumer 900W PSUs are probably pure BS.

My company's newest blade enclosure has six 2400 W PSUs Granted, that's for 3+3 redundancy, but it sucks a whole lot of juice.

As for consumer PCs...

Intel Core 2 Extreme Quad can use up to 136 W at 3.2 GHz, the overclocked versions I'm sure go higher.

nvidia 9800 GX2 runs at 365 W at load, times two, equals 730 W.

10k RPM HDD(s), WD Raptors run 10 W at load, let's say you're a fool who runs two in RAID 0, that's 20 W.

Right now we are up to 886 W under load without taking into account cooling, optical, motherboard, network, sound or effects for those silly tweakers. Plus you never want to run your PSU at max load, if you can help it, since that degrade efficiency, so if you have a beast of a system, like shelled out $6k-$8k for one, then a 1200 W PSU would not be too much of a stretch.


For most purposes you don't need more than 600-750 W for a gaming system, depending on GPU configuratio, 450 W for a moderate gaming system, 350 W for a decent gaming system, and 250 W for mr. el-cheapo business/internet machine. IMO.

HP or IBM blades? Or maybe Dell or Supermicro? I had HP C3000 Shorty on a demo for a while. The awesomeness (and loudness) of fans on that thing dwarfs any enthusiast rig.



You rotate that red handle and fan module comes out. The module is about 25cm long.

This is our newest monster:

It's a sweet blade enclosure. It's just really big and heavy and expensive.

That's a beast. How loud is it? Love a good rack server but quiet the are not.
