[PCPer] XFX has a PSU for those looking to power multiple GPUs... - Page 10

post #91 of 108
Good thing my dad is a an electrician. I could get him to install a 240v outlet for me. tongue.gif

I do have a ~2400W 240v PSU I nabbed from work. The server was unsellable, so we gutted it for parts. The PSUs aren't compatible with the other servers we have, so my boss let me have it.

So, I have ~2400W server PSU that supplies up to 200A @ 12v. Can't use it here, though.

Lucky man. I had a sparky out here today and a 240v 2A drop will run me about $300, which isn't too bad in my eyes. Still, that's 32GB of RAM... oh well.

Yeah, both sides of my family have histories in various trades. My dad's an electrician, my grandpa worked in a motor shop, I have a mechanic, HVAC installer, plumber, another electrician, and welder among my uncles. I help them with computers, they help me when my AC goes bad, car breaks down, etc. It works out pretty well. thumb.gif

While it uses good internals(SeaSonic), it's still XFX and i'd rather go with Corsair or a SeaSonic it's self for my own reasons. Thanks.

Which is precisely what I was asking you to clarify... Instead of just saying "XFX, no thanks" why not support that viewpoint with some information/reasoning and actually add to the discussion. Your statement added nothing insightful to the conversation.

Man, speaking of XFX, I hate their reference GPUs! I mean, they're the same as every other reference GPU, but I hate them! Because they're XFX, being all... XFX-ish, doing their XFX things. As soon as they get the perfectly good shipment from Seasonic, they destroy, no, DEMOLISH, their great design when they stick the XFX sticker on there. Damn them! rolleyes.gif

The actual scenario it protects you from is this, and I'm going to use a real life example. User has a single rail Ultra X4 1600W (which is really a moderately decent 1200-1400W) and a high end system with an MSI motherboard. Oh no, MSI's shoddy engineering and low quality transistors mean that a fet in the VRM fails shorted, causing a short circuit. 100A are immediately drawn through the EPS12V connector, setting it on fire. The huge transient load damages the power supply's +12V rectifiers causing a voltage spike and the PSU to shut off, and molten plastic from the burning motherboard drips onto the graphics card, damaging it.
Now let's replace that single rail 1200W PSU with a multi-rail 1200W PSU with OCP trip points set at 36A. Oh no, MSI's shoddy engineering and low quality transistors mean that a fet in the VRM fails shorted, causing a short circuit. 100A are immediately drawn through the EPS12V connector... and the OCP protection activates and shuts the PSU off within a few milliseconds of the load occurring, before the connector catches on fire. Motherboard is still dead, but no further damage occurs.
THAT is why you have multiple +12V rails.

Nice post, thanks!

But just wondering here, if you then get a motherboard with high quality transistors and good VRM's, would it then be a problem to use singlerail under benching and such?

Thanks!
