Faulty PSU?

[dava6711]

Hi

I apologise in advance for this newbish question!

I turned on my PC yesterday but it failed to boot, I tried several times but it never once booted into windows, it never even reached the "hit delete key to load bios"?

Luckily, my wife has a PC too, so today I removed all the components from my PC, laid them out onto cardboard and hooked up the bare minimum peripherals needed to run my PC. I tried to start it with my current PSU, but again, it failed to boot. So I hooked up my wife's PSU, hit the power button and it started flawlessly.

Does this mean my current PSU is toast or could something else be a factor? I've tried clearing the CMOS via the MOBO's jumpers, removed the CMOS battery and tried different RAM configurations (like switching slots and installing one through to all four modules) etc but it always fails to boot with my old PSU?
Is there anything else I can try, any other component that can cause this kind of behaviour or is it definitely my damned PSU?

I've had the PSU since 2007 and I've never overclocked this setup.

I have an asus P5E3 deluxe MOBO
Intel Q9550 CPU
4 x 2Gb of DDR3 RAM (micron MT8JTF25664AZ-1G4D1)
An XFX 7870 GPU
Mushkin HP-580AP PSU
Prolimatech megahalems heatsink
Antech P160 case
Running windows 7 64bit ultimate edition

Thank you

sounds like you need a new psu to me if it was fine with the other one
without spending too much on a decent psu :-
non modular

if your not bothered about the wires then just get the superflower

Well, you`ve pretty much solved your problem.
New Psu.
What Psu is it?

Pretty much I think, it'll have to be replaced. There's loads of good cheap ones out there though, don't worry too much

God damn it, thanks for the advice though. There goes my DOTA 2 marathon lol. I'd like a premium, fully modular PSU up to 750w as I want something that'll last me a long time. I hear seasonic are the best, do you know if this is this true?

Superflower are supposed to be better (I think) - not sure about that, just look for an 80 Plus Gold/Platinum one for top quality - platinum ones aren't really worth it though, they save like about £2-£3 of electricity per year.

 

[dava6711]

It's a mushkin HP-580 AP, I've listed all the system specs at the bottom of my OP.

 

[dava6711]

Never even heard of superflower before, I'll have a look now.

YOUR BASKET
1 x Seasonic G series 750w '80 Plus Gold' Modular Power Supply £109.99
1 x Be Quiet Power Zone 750W '80 Plus Bronze' Fully Modular Power Supply £99.95
1 x Corsair RM Series RM 750 '80+ Gold' 750W Power Supply (CP-9020055-UK) £99.95
Total : £323.39 (includes shipping : £11.25).



Looking at your specs a 550-650W would be more than enough.

 

[dava6711]

Didn't think I'd get a quality one for around £100!

Thank you for your advice it's appreciated.

I just read a review for a sunflower PSU that was basically flawless and fully modular but it was 1000w and I don't need that much power! Shame....

Looks like it'll be the seasonic model.
