$2500 Custom built PC won't start

hey guys i recently purchased these PC parts, and once put together the fans turn on for a quick moment and shut back off, then nothing happens. when i disconnect the power cable and reconnect it, it happens again.

I tried taking the whole thing apart and reinstalling all the component but i still can't seem to find where the problem is coming from:

Intel Core i7-3770K Ivy Bridge 3.5GHz


GeIL EVO Veloce Series 32GB (4 x 8GB) 240-Pin DDR3 SDRAM DDR3 1600 (PC3 12800) Desktop Memory Model GEV332GB1600C10QC

Seagate Barracuda 3 TB HDD SATA 6 Gb/s NCQ 64MB Cache

SanDisk Ultra Plus SSD 256 GB SATA 6.0 Gbps


Thermaltake Black Widow W0319RU 850W ATX 12V

if you guys can tip me out here it would be greatly appreciated.

  1. just because it costs a lot doesnt mean its not prone to failure. Most likely a bad power supply or the motherboard. If you have a spare psu, put that in and see if the computer boots up
  2. Try it with disks disconnected and only one ram stick.
  3. i do not have a spare PSU at the moment, ill try getting a cheap 650W alternative just to try, thanks guys. if anyone has more suggestions im wide open

    Probably the PSU. Don't buy a cheap one, they can sometimes fry your parts. Only get PSU's from Antec, Corsair, XFX, and Seasonic.

    hes only using it to test the pc and see if it turn on. any cheapo one will be fine for that. Just in case i would not plug in the dedicated gpus and just use the integrated graphics for this test.
  6. thank you all for your responses, went and got myself a new motherboard and PSU just to save myself another trip to compusa.

    didn't even have to open the motherboard, faulty psu was the issue, learned my lesson on Thermaltake tho :))
  7. Actually, a cheap GPU can fry a system, regardless of how much wattage is being used. Fires, sparks, and more can be caused from one being used.
  8. Another good PSU manufacturer is FSP (Forton Source Group). Thermaltake is a good brand, so I would try for an RMA and get a decent PSU from a friend and do a POST test, if it posts and begins loading windows, then you are good. It is also possible that the PSU you have is fine and the parts you are using are pulling to much wattage, but that's unlikely with a 850W. Grab a voltage meter from a local hardware store and test the PSU's voltages (does not need to be plugged in for volt tests).
