Whats the difference between these power supplies? any recommendations?!

[5aboy]

Hi,

I have a fairly high-powered system (opteron 165 / 1gb ram / 3 hdd / 2 optical / 7800GT / dfi sli-dr) and am about to replace my tagan 480W PSU.


I have seen two units that to me seem identical, but have different prices -can someone please tell me why one is more expensive and if they are different? the model name appears to be the same for each:

LN12511
560W Silverstone Strider ST56F Quiet SLi 2xPCI-E + 2xSATA EPS12v ATX Dual 12v v2.01 120mm Fan PSU

(88.07)
and

LN12878
560W Silverstone ST56F Strider 80% + Eff' 120mm Fan Dual + 12V Rails PCI-E SLi ATX12x 2.01 EPS 12v

(75.19)


which would you recommend? going to buy ASAP. also is there anything else you could recommend for me?


thanks!

Seasonic S12 500W,

Quiet, stable.

Silverstone PSU's are good but not as quiet as other makes.

I think thats an error.

[jonny4288]

buy reading the decription one has two pci express power plugs, whilst the other has one,

[Lee H]

oops.

The warehouse team have been checking both the stock codes and 1 of them is infact the zeus model and not the Strider series as stated.

Once they've checked all the stock the website is going to be ammended - with the right PSU renamed.

Best Regards,

[5aboy]

thanks for that - im liking the seasonic's but they are quite expensive.


hows about the silverstone st60F?

any ideas?!

Why do you want to replace the Tagan ?
If thats all you have in your system, its not even coming close to 480 watt.

[Noni]

Yep, most high end systems dont use more than 430W.

[5aboy]

well, i am inclining to disagree with that.

I dont like the fact that the PSU does not deliver the right voltage to the chip - if i set it at 1.45V itll hover at 1.4V and sometimes lower. 12v reads 11.83, although 5 and 3.3v are looking good.


its just that i think slight voltage fluctuations are responsible for random reboots - my chip does do 300htt (but for this i must set cpu volt to 1.55 and it gives it 1.5, and its perfectly stable), and my ram definately does 300 2.5-3-3-5 1t as it is memtest stable.

i also am beginning to think its quite loud (not as quiet as my previous tagan, i had it exchanged, they sent me a new one, and im selling it on)

so im leaning towards the seasonics as ive only heard bad things about the higher powered tagan units, else i wouldve plumped for the 580w easycon version.

[Noni]

If your using a software from your computer to monitor your PSU voltages they are going to be WAY off.

If your overclocking thats the answer to your reboots, try running PRIME 95 for 12-24 hours and see what happens.

Its not loud at all, look at other sources in your case.

Seasonics are great PSUS!

Im not saying DONT buy a PSU, but check to see whether its DEFINATLY something you want to change.

Good luck.

[5aboy]

Yeah, I totally understand you but I have people interested at the £50 mark, which was around what Id paid for it initially, so if I sell it im really just at square one.


Seasonic S12 -600 is probably what I am going to go for, even though it is not modular, which I would prefer and the silverstone is apparently hideously loud.

[Noni]

Seasonic S12 is a great choice, quiet and really stable!

Go for it then mate. Good luck.

....Seasonic S12 -600 is probably what I am going to go for, even though it is not modular, which I would prefer and the silverstone is apparently hideously loud.

I've got the Seasonic S12 430 version: You don't say what case you have - just point out if you have a P180 case the power cables are a tight fit.

[5aboy]

I have the fulltower chieftec case, but the power supply is closer to the motherboard than the top of the case, so there shouldnt be anything to worry about!

Have to say I'd agree that 480W is more than enough for your system. Voltage fluctionations to the chip aren't the fault of the PSU, they are caused by the voltage regulators on your motherboard. If you want rock solid volts then you need 8 phase regulators, which are hard to find on non-intel boards, even the best AMD boards usually only have 4, and mine's only got 3. In addition my motherboard deliberately fluctuates the voltages a tiny bit to create a less sharp EMI pattern.

[5aboy]

yeah people are saying that, but all of the PSU calculators say I need a 585W PSU to get me going at 80% load.

I really dont know anymore, I know that the seasonic is the way forward, but it is awfully more expensive than the silverstone, the tagan 580, and quite a few 600W PSUs.

I'm using a Tagan TG480U01 (original version without the PCIe connector) and an Asus A8N32-SLI board. I used to get about 11.78 - 11.85V with the A8N-SLI Deluxe board that I had, and it would reboot sometimes for seemingly no reason at all (it wasn't related to load). I thought my Tagan may just be crapped out, but anyway..
Since I've switched to the A8N32-SLI, I've got a rock steady 12.03V, it never fluctuates, and I haven't had a single crash. Just adding my $0.02. All other rails are dead-on.
The 8-Phase solution really does seem to work...
