Problem with PSu?

I'm builing a custom comp and here are the stats:

SAPPHIRE 100129FB Radeon X800GTO 256MB GDDR3 PCI Express x16 FireBlade Edition Video Card

AMD Athlon 64 X2 3800+ Manchester 1GHz FSB Socket 939 Dual Core Processor Model ADA3800BVBOX

Rosewill 1GB 184-Pin DDR SDRAM DDR 400 (PC 3200) Unbuffered System Memory Model RW400/1024

Maxtor 120 GB HD

CD Rom

DVD R/ CD R combo drive.

ABIT KN8 SLI Socket 939 NVIDIA nForce4 SLI ATX AMD Motherboard

I am currently using a 480 Watt PSU, but it my comps keeps going black screen on me, and i can't restart it. I still see lights on my tower, and hear my tower running, but when i press the restart button, i get no response. I would have ot manually shut down and turn it on again. Now my comp can not turn on for more than 5-10 minutse without going blank screen again....would this be a problem with my PSU?? If so, what PSU should i get?

  1. Yes it could be the PSU. I would recommend an Antec, Fortron FSP group, OCZ, Silverstone or similar quality PSU.

    How many brass standoffs / spacers did you use?

    It might also be bad, flaky or incompatible memory.

    If you have any compatible 184pin DDR SDRAM you know works for sure try it and see.

    Some boards are very picky about RAM.

    Is your machine beeping during boot?

    Did you try resetting the CMOS/BIOS?

    Good luck! :D

  2. How many watts should i get?
  3. I would say get a decent 520+W [ Antec, OCZ, fortron, etc ]

    Keep in mind a cheapo 480W or 520W is actually equivalent to a decent 350/380/400W PSU from Antec, OCZ, Fortron, etc.

    I couldn't exclude the bad brands, sorry.
