New System Build Problem

Hey guys

I recently bought new components to build a PC of the following spec.

Intel Core 2 Duo E6750 @ 2.66ghz
2GB Crucial Ballistix PC2-8500 1066mhz ram
BFG GeForce 8800GTS 640MB
OCZ GameXstream 700W PSU
Samsung SH-S203B 20x DVD-RW
2x 250GB Seagate ST3250410AS SATA II HDD
ThermalTake Tsunami Case

Now my problem is, when i attach the 3 case fans to the PSU everything loads up fine and i get the BIOS. However, if i plug in the HDD's, the PSU blips on then goes off immeadiately and everything stops. I tried unplugging some fans and putting hte HDD's in and get the same problem. Can anyoen shed some light as to WHY?

ALso, should there only be one lead from the PSU into the G-Card? Or should there be two, because i can't find a second slot to plug stuff in.

Strange... GameXStream 700W units are comparable to the NeoHE 550W or Corsair 520W in power output on the 12V+ rails, so you should have no problems there. Try with only one HDD, maybe you're overloading a rail, if it doesn't work then try with another PSU, if that works then it sounds like a faulty unit to me.

I don't know if it's still around, but as stupid as it sounds some ASUS boards dislike some PSUs, but then again it's ASUS, so I wouldn't be surprised if that was an issue too.

Ive tried with only one HDD, and also 2 fans with one HDD, and it still doesnt work. But with 3 fans, it does.

Try not to overload a single rail with too much stuff, see if that helps.

ive even tried using the independant sata power cables the PSU has to no avail.

Try with another unit, if it works, then RMA.

OKay, im going to try and stick the HDDs in this current unit, if they work, then do i assume its a PSU problem?

Just also to note, everything runs, i even stuck the DVD-RW drive in today, its just when i try to connect either HDD, and i'm not overloading any rails, only one or two attachments to each rail.

try removing the HDs from the case, and plugging them into power plugs to rule out a short caused by the HDs.

What do you mean, plugging them into power plugs? (sorry if i'm bieng stupid!)

i took the hdd out of the chassis and lay it on an anti-static bag, and plugging into the PSU and mobo, and all i got was a quick squeal from something then when the power died so did the squeal

Looks like one of the rails on that psu is not pushing the right wattage. Usually with a 500-700 watts psu the single hard drive rail should be able to handle at least 3 hard drives. Like I the psu is funny so you might want to get a good one. Don't push your luck on that psu or you might end up frying the rest of the system. Get a replacement already.

well it turns out both HDDs AND the PSU are buggered. I can't run my old HDD in the new system, and i can't run the new HDDs in the old system either.

Sorry correction, the old hdd works in teh new system, so its seems as though its the new HDDs. I'm going to test further and stick one new hdd in this current system with my old one, and see if its starts up. If it does ill see if windows recognises it.
