Hey,

I currently have a Tagan 480-U22 running my system and it has been utterly flawless. Quiet and powerful.

It also feels amazingly well built, unlike an OCZ 750w PSU i hastily purchased and subsequently took back a while ago. When the draw ramped up on this, it turned a quiet PC into a nightmare.

The Tagan on the other hand, simply refuses to make a noise, even when subjected to the abuse below.

As of yesterday, my PC spec is:

Core 2 Q6600 @ 3.6
2 HDD
1 SSD
GTX 570 SC (no OC yet)

Now, with all of the above.....my system surprisingly runs just fine, even when benchmarking.

The PSU however seems to be buzzing or whistling when under load so its obviously being stretched and i dont want to subject it to maybe 3 hours of gaming in that state.

I do plan on bumping the clocks on the GTX570 soon as well.

I know my Tagan has 30Amps when both rails are combined (not entirely sure how this happens but hey) and as I understand it, the 570 needs at least 36Amps on its own.

So i guess that based on what I have said above, I am hopign that board members can recommend a PSU.

My budget? 60/70.......if cheaper then good.

And I want to consider the build quality and noise.

Any thoughts appreciated.

Regards
Andy
 
The 570 is rated at 219 W (19 A).

The buzzing or whistling is probably capacitor whine. If so it's just the capacitors vibrating, and probably not due to overloading. It's annoying, but it shouldn't blow up.

If you were overloading it you game experence would surely be affected. :)
 
Is there a chance that the Tagan is up to it then?

I paid a good bit (relatively) for this PSU back when i bought it as i am of the "buy good buy once" philosophy but could it really be managing this load ok?

Cheers
Andy
 
I would say no, and certainly not with that CPU overclock.

Effectively the Tagan is a 360 W PSU. Any high end gaming would likely exceed on your rig. Even with the CPU at stock speeds you be just over the that. :/
 
aye. The 550W is only £5 cheaper, so the 650W is better value,even though the TP-550 will be enough.

Also good are the Corsair TX650 V2, and the XFX Core 650W. That's for single GPU. For 570 x2, you would need 750W Corsair / Antec / XFX withi 4 PCIE connectors. Lepa 850 can also work. 850 will give you plenty of headroom (OCZ-Z850 altohugh you may not fancy OCZ), Corsair TX, XFX Core (the XFX Core PSUs are almost identical to the Corsair TX V2 equivalents), ...
