SeaSonic X750 [serious question]

post #1 of 18
Thread Starter 
I really need to know what's going to happen when this unit arrives and I decide to go with Intel (which I promise is happening within one month-one year).

I saw this review on Newegg regarding the SeaSonicX750 that's on it's way to my home:

"Cons: WARNING TO MULTIPLE GPU + i7USERS: This is a modular PSU, so there are two specific slots on the back that can only fit your PCIE power cables. Problem is, that if your motherboard/CPU uses an 8-pin power connector (like my Intel i7 does), then IT TAKES UP ONE OF YOUR PCIE SLOTS AND LEAVES YOU ONLY ABLE TO USE TWO TOTAL PCIE POWER PLUGS! This is an enormous oversight since most high-end GPU's require two PCIE power cables for EACH GPU. Just plain idiotic"

At the time being, my AMD CPU/MOBO does not require this type of PSU connection.. (EDIT: well, I think the ATX power cable is 8 pin, not sure if this is the same thing he's talking about!!) and if such a thing is true that the intel i7 does (not sure which he's talking about), then I won't be able to SLI my 470s (waiting for SLI hack, SLI bridge to arrive, and the PSU. Each 470 needs a 6pin connection, and I haven't received the PSU yet or researched Intel CPU/MOBOS.

Can anyone chime in?

Err that only applies if you need 2 8 pin mobo power connectors for some odd reason (like an SR-2).

You can have a total of 4 PCIE 6+2pin connectors and 1 mobo 8 pin connected, or 2 PCIE 6+2 PIn and 2 8pin mobo 8 pins connected.

The reviewer clearly doesn't know how to read the manual that came with it.

Edit: I can have the identical AX750 myself and can confirm this as well. I've got a few pics in my build log of it as well you can look at if you want more proof thumb.gif

This is why you shouldn't read newegg reviews(because most reviewers there lack active brain cells) and also why you should actually know *** you are buying...

The X750 comes with 4x PCIe 6+2pin connectors and 2x EPS 8pin connectors and iirc one 4+4pin ATX connector too..

I have the x650 and that's not true with mine you can plug in a 4pin(x1) 8pin(x1) 6pin(x2) and 6+2pin(x2) all at the same time with your varying molex and sata power

My mobo has two 8 pin cpu plugs. But I only need one of them. Two are for more power for LN2 sessions.

If you want or decide to use two on your mobo, you'll only be able to use two pci-E cables for that one big graphics card as the cpu 8 pin will use one of pci-E connections(insert) on your psu.

So one 8pin cpu and 4 pci-E cables for two graphics cards(GTX480s for eg.) or two 8pin cpu plugs and one set of pci-E cables for one say GTX480.

Eh don't worry about it. I stopped reading newegg reviews a long time ago after half the 1 star ratings for that PSU were because the fan wasn't spinning and they though it was DOA...

Seasonic even puts a massive sticker on the PSU covering the connectors, with huge bold print on it saying that the PSU doesn't spin at low load. No idea how those people could possibly miss it...

Nope, stop giving poor info please.. and also, the EPS and PCIe are not electrically the same, they don't work off the same PSU connectors.. common sense.

Actually he's is correct I have the x650 and its the same way the pci-e plugs say on them pci-e/CPU so yes they are both from the same plug
