I think my PSU has died.

[cdawall]

well... its a 5yo psu.

i dont think a PSU have degraded capacitors within only 5 years. Please correct me if im wrong

and this PSU have a lot of protections (OVP/UVP/OCP/OPP/OTP/SCP/OLP), so i dont think its gonna fry your hardware.

But thats just my opinion.

I would take a fell several tests to see if a new psu is REAAAALY necessary.

PEACE!

All the protection in the world doesn't help when the rail spikes. His issue is likely that the PSU doesn't have a strong enough 5v rail for that many hard drives. Stress testing will likely never reveal an issue, but that doesn't mean his 5v rail is staying within spec. One nasty transient and he has no more data. Data recovery starts at $700 for one bad drive that needs more than an anti delete program. I would say a $120 for a power supply is well worth the piece of mind.

Thanks for that, I hadn't realised, I'll check my warranty status.

I looked them up because I was curious it would be worth the effort to RMA it in my opinion. At worst replace and sell the RMA.

Do you think it may be a bad SATA power connector? Try a new cable?

As for PSU brands I like Seasonic, Corsair, and EVGA.

Ha so Seasonic, Great wall and superflower?

 

[jboydgolfer]

id give you my old Corsair 600W , but i couldn't afford to ship to the UK sorry. it would be likely similar costs to just buy a new one. hope you get it resolved.

 

[bubbleawsome]

Also, I would sell the RMA unit and buy a new one from a better brand. CM isn't bad but they had a bad time a few years back.

That's what I was thinking of doing

OK man, I've take a look around about your PSU. It's old indeed and is Fortron based.
Unfortunately it's a group regulated PSU and it doesn't do good in crossload tests (exactly what you are doing at boot with your HDD farm, you overload +3.3V and +5V rail and barely use +12V rail).
From jonny's review

Another thing this table tells us is that the unit is not independently regulated, like most units this size. It's using a cheaper group regulated design. How do I know this? I'm psychic. But seriously, take a look up there at the voltage readings for tests CL1 and CL2, the crossload tests. See the 12V and 5V numbers? How they are almost out of spec on the 12V side and out of spec on the 5V side? That's group regulation there, guys. That's the OEM saving some money by making two rails share one filter coil on the secondary.

So I must join the guys who said that it's better to buy a new PSU from our days.

 

[Darknova]

Thanks for looking in to that burebista.

Any suggestions on a 1000W PSU to replace it?

There are quite a few, what features are you looking for? Silent modes, cable outs?

 

[Darknova]

Quiet, Fully Modular, High efficiency. About it really.

These aren't a bad value for 80+ platinum 1kw units, do they have them over in the great UK

http://www.newegg.com/Product/Product.aspx?Item=N82E16817207019

but, these as well

I can't get the XFX, I can get the bequiet!, but the closest seasonic I think is this one

Here is the review of it CL1 test is the one that matters to you. That is the full load on 5v rail testing.

 

[OneMoar]

1000W seems a wee bit over kill there are plenty of 750 to 800W platinum units

 

[EarthDog]

No EVGA Platinum units available there? Best bang for the buck really... Supernova P2 series...: http://www.amazon.co.uk/EVGA-SuperNova-Platinum-Modular-Supply/dp/B011RGX5MU/ref=sr_1_1?ie=UTF8&qid=1455050230&sr=8-1&keywords=EVGA+850W+P2


I don't see the point in a 1KW unit honestly... a 750W would be fine. Id go 850W if you plan on overclocking that CPU further and the GPUs.

 

[Darknova]

This is what my preferred retailer has listed

You just need to take the selections people have given and look them up at your etailer of choice....

Here is the 850W P2 @ scan.....: https://www.scan.co.uk/products/850...platinum-atx-fuly-modular-sli-crossfire-ready

This, you have to remember that PSU's have efficiency curves and manufacturers typically target 80% load as the point where the psu is most efficient. The OP's rig seems to me to be in the 500 watt range maybe 600 max. Soa 1KW unit would be at 50%-60% load at that point, not the most efficient part of its curve. a 750 would be closer to 66%-80% a more efficient part of the curve. While true new rigs down the line will have different wattages, the current hardware changes seem to be less wattage for more performance.

I say go for a decent 750 and you'll be fine, even if you plan to crossfire.

[EarthDog]

Agreed...

But just note that the difference is really only 1-3% across the entire power band on most units.

People seem to be nervous about running their PSU up at that 80% range which is MY sweetspot. Not many have the bawls to run an overclocked 5820K (4.2 Ghz 1.2V) and a R9 295x2 on a 750w psu. When benching, I would hit over 800W at the wall (CPU at 4.8 GHz, GPU maxed out).

I used this PSU Calculator (appears to be based on eXtreme Power Supply Calculator which I've used in the past) which was saying I needed 808W at 90%, I was just adding 20% (969W, so 1000W is the nearest), is this the wrong approach then?

 

[trog100]

i have a fully modular 850 watt EVGA supernova G2 that came from scan.. it seems to happily run my system in eco mode.. it never seems even warm to the touch and i cant hear it running.. it was around £120 if i remember correctly..

They are overestimating things there. They think my system pulls 360W, while in reality it pulls less than 230W (during Prime95 and Furmark no less).

I'm pretty sure it is only saying you need that much because of the HDD spin up spike. Spinning up that many drives at once(I believe you said 7) is a killer on PSUs. That is why most controllers that support that many drives use something called staggered spin-up. Where they only spin-up a few drives at a time. Most onboard SATA controllers don't have this option though.

theres a guy at work with 8 hard drives running on a phenom 1 and a CX430 at work we are taking bets to see how many power cycles it will take before it will fry

Not long those are group regulated junk...
