Rosewill PSU DOA..what now?

Just built my first ever rig, a $740 budget gaming PC:

1) $110 MOBO: ASRock 970 EXTREME4 AM3+
2) $90 CPU: PhenomII x4 840 on eBay
3) $50 RAM: 2x 4GB G.Skill DDR3
4) $65 HDD: Western Digital WD7502AAEX 750GB 7200 RPM 64MB Cache SATA 6
5) $45 DVD-R: HP 1260i
6) $100 PSU: Rosewill RX850-S-B
7) $130 GPU: Galaxy GT 465
8) $50 Case: Rosewill Challenger
9) $100 OS: Win7 64-bit

Or should say assembled my first rig, as after installing all components, no power. Tried a different cable to a definitely hot lead, but nada. The Rosewill RX850-S-B 850W Continuous @40°C ,80 PLUS Certified, ATX12V v2.2 & EPS12V v2.91, SLI Ready CrossFire Ready apparently DOA. No blue lights, nothing.
I'd had a horrible feeling I'd goofed somewhere on the installation, but used a guide to assembling a PC, and followed it to the letter. Got MOBO connected. Got case switches & data leads connected to it all connected.
But no juice.

As I've never done this before, what now are my options?
Are there any additional hoops I need to go through to RMA the product?
Will I get my money back (preferred!), or just a replacement PSU?

Any advice most appreciated.

  1. contact newegg and inform them the PSU is DOA, they will email you a shipping label + refund your money

    then get this corsair PSU for $84 + free shipping - 10% (code EMCKAKA24) - $15 MIR = $60 after you get the rebate check
  2. Make sure there isn't a voltage or on/off switch on the back of the PSU that needs to be flipped. If not I'd try the PSU paper clip trick to be sure the PSU is really DOA.
  3. video how to on the paper clip trick
  4. Thank you dirtyferret. I was planning on SLI'ing two GTX465's though...will 650w be enough?

    Thank you beenthere: flipped switch back and forth.. But what is this PSU paper clip trick?

    After buying the PSU, did more research and determined that an 80+ Bronze, preferrably from a mfg. like Corsair is the only sensible option...too many horror stories of lesser quality cpu's frying mobo, gpu, etc. to go with anything of questionable quality, just to save a few bucks. So I'd really prefer to return the existing unit. But I burn with curiousity to know if I fu$%ed up the install or no.
  5. Did the paperclip trick: the frickin' PSU works!

    Oh, what? Guess that means my MOBO's damaged?
    Any ideas, links to guides, etc. on troubleshooting MOBO issues?
  6. Thanks lilotimz,
    used PSU calculator here:
    factored in cpu OC'ing to 4000 (which hopefully will be equivalent to a Bulldozer in 2-3 years time), and an extra case fan.

    It gave me: "624w (674w recommended)"
    So I guess 750w should do it, (as I plan to use this rig for next 4+ years)??

    EDIT: Just purchased the CORSAIR Enthusiast Series TX750 80 PLUS BRONZE.
    Thanks lilotimz
