Power supply requirement

[ant80]

Hi, I have a new comp...
athlon64 san diego core 3700+ cpu,
the MSI Neo4 Mobo,
2 hard drives ,
and an Asus Geforce 6800GT Graphix card.

Unfortunately, when i power it up, NOTHING shows up on the monitor (which works). The diagnostic leds, all light up red and stay that way (which says that the processor is either damaged/not mounted properly).

My question is, is it possible for it to be a problem with the power supply? I only have a 300W power supply. is it sufficient?

Its mainly about quality, not quantity (at least to a certain extent)..

What brand is that 300W??

Reseat the CPU; all the memory... double check everything

and , on a last note.. if you decide to get a new power supply.. something in the 350-400 watt range.... alot of forum users recommend the low cost, but excellent Fortron power supply.

you don't have enough power. I'm sure that others can give better reccomendations than I can, but with an nforce 4 mobo and a 6800GT, you want something more in the 400+ watt range with a lot of ampage on the +12v rail.

Therefore jlbenedict's right... A high quality 300W should be able to power it... I'm not saying it'd under heavy load, but at least let it POST... But buying a new PSU would be a wise decision, take yourself a Fortron, they're cheap, quite powerful and very stable...

Try reseating everything... Boot with as less as you can (CPU, HDD, KB, 1 Optical Drive, 1 stick of RAM and your Video Card)...

If you're still having problems with that, ditch the HDD and the optical drive to see if it'll post.

Make sure all your cables are connected. There should be two main power supply plugs (20 or 24 pin and 4 pin) that go into the motherboard, make sure you've got both plugged in. Plug in the video card.

It would be enough to light things up, you have other problems...........

Thanks for all your input. I changed the mobo and it is working now.

But I will take your advice and buy a new psu. I looked on Newegg, and they have different classifications for the "type" of the psu. What is the difference between ATX and ATX12V? Which one should I buy? Thanks in advance.

ATX12V is the one you'd be looking at... Find yourself a power supply that has dual 12V rails, 24-pin or 20+4-pin main connector, 6-pin PEG connector, SATA connectors and preferably some form of PFC (whether it'd be Active or Passive)... Sleeved cables are always nice...

EDIT: It lacks the last two "requirements", but the Fortron AX450-PN is a great PSU at a great price...

Thanks for the info. I have a few questions about this though.

Why do I need a dual 12V? There is only one 12V power connector on my mobo. Is the other one for the 20+4 pin main connector?

Secondly, would this do? If not, what does it not have thats not good? Apart from it being 400W that is.

Also, what is a PEG connector? Thanks.

That Forton Group one works. Notice the 12v1 has 14 amps and the 12v2 has 28 amps. This is crucial for a high performance video card. Not sure about your other questions, though.

A PSU with dual 12V rails has the ability to let one rail feed the processor and on-board peripherals, while the other one is dedicated to the graphics card... It makes sure that the two "power-eaters" (CPU and GPU) get their power independently... This technique is now used for most of the new PSU's because it delivers a stable power and makes sure there aren't as much fluctuations...

A PSU with one rail powers everything through that one rail, and when it's under heavy load, it can drop significantly (high quality PSU's don't of course, but they cost a lot)...

That Fortron you pointed out will certainly suffice, but the one I advised you (Fortron AX450-PN) has more power, and is cheaper... Feature-wise they're the same, with the latter only lacking sleeved cables...

A PCI-Express Graphics connector is meant, like it says, to power your PCIe graphics cards... These need a special 6-pin connector, instead of a regular Molex...
