Trouble booting

just build a new system

AMD Phenom II X3 720 BE
some random Coolermaster until i can get a new mounting clip for my Zalman 9700
Asus M4A77D
XFX Radeon HD 5750 1gb
2.5 gb of various DDR2 ram
500gb western digital hard drive
Black Steel 480w power supply

so i've gotten windows installed, all updated, done some light gaming and prime95'd it for stability and it all checks out.
but sometimes when i restart it or just turn it on it does post and just keeps cycling the power supply on and off.

if i hit the reset button or the power button it will usually break the loop and it will post and be all fine.

my question is why is it getting into this loop?
is it possibly shorting somewhere, or maybe my power supplies not strong enough

  1. It could be that your PSU can not deliver enough juice.
    Black stell is not...well...try Corsair, Enermax, Tagan, Antec, Silverstone, Seasonic, or PPC instead.
  2. i'll probably look into getting a new power supply... any recommendations on a fairly inexpensive one, preferably a quiet one... this black steel is one loud hot monster
  3. http://www.newegg.com/Product/Product.aspx?Item=N82E16817139004
    That should be enough and some free room.
  4. +1 corsair
  5. btw your current psu SUCKS!

    Thermaltake Toughpowers Like Mine Are Fairly Inexpensive And Quality PSUs, Just Dont Plan On Running A Graphics Card That Requires More Than A Single 6-Pin Connector, But With Your Setup It Shouldnt Be A Problem, Stick With My Following Reccomendations Below And You Should Be "GTG";

    1. NAME BRAND!
    2. Active PFC
    3. 80+ Cert
    4. NO-LESS Than 550 Watt Minimum
    5. No More Than Dual-Rail (A Single-Rail Is Prefered)
