PSU advice (Corsair, Seasonic, XFX models and ?)

[Duvan]

I need a PSU not only for my current dual core computer but maybe more for when I buy a new rig in 1-2 years. One decent to good CPU and graphics card, 2 HDD:s is enough in the future, but I need the PSU to last/be sufficient for many years hopefully. Preferably one that doesn't start burning
Anyway, my main concern except for that is that it's fairly quiet.

I looked at:
1. Corsair TX 650 V2.
But I read the TX 650 (not V2?) runs warm, This the case for the V2 too?
"Both intake and exhaust temperatures rose a bit faster and higher than in most other PSUs. The exhaust air temperature exeeded 50°C at just 250W and rose to over 70°C after about 15 minutes at continuous full load"

2. The TX 650M instead. It's less hot, and more quiet eh?
I read the HX650 does not run as hot, but they cost too much here.

3. SEASONIC 620W POWER SUPPLY S12II620

Is this one dated? But it's more silent and runs cooler than the TX?

4. XFX 650W Core Edition ATX, 80+ Bronze P1-650S-NLB9 (or 750 watt)

How hot does this one run on higher wattage? The thing that concerns me is that the fan might be noisy? I read in a review for a similiar model (XXX ed.) that the Bronze version was quite a bit more noisy than the silver at least... Which is too expensive here.

Is XFX otherwise as reliable as Corsair/Seasonic?

5. preferably NOT antec. I had 3 of them break the last 6 years, even if I know it's got more to do with my model being crap


Also, please, if there is any other models I should be looking at instead, let me know

I believe you but well, HCG-620 was the only Antec that seemed interesting, but not in stock in my country. (The truepower 550W is also for example 36€ more than the XFX and arount 15-20€ more tha the other ones so quite pricey).

For 125€ here:
Antec TP 650 watt
XFX XXX ed. silver 750 watt
Corsair 650HX

For 135€ - 147€ Corsair AX 650 watt

For 155€ Seasonic X 660 watt

For 160€ Corsair AX 750 watt

Noise is still my biggest concern... In a review I read the AX650 could make some noise at high fan speed... The x660 the best at noise reduction? But then again it only has 5 years warranty.

Probably impossible to say, but would the Ax 650 watt be sufficient for a computer in 5-6 years too with a single GPU... I mean how much has power demands increased the last 5-6 years? And even if I'd buy the 750 watt I guess nothing is sure? heh.
How much would even be needed for a quad core CPU plus 2 HDDS, a dvd station and a good GPU today?

Thank you!

Hmm okay, is it just the gold models, the AX and the X that can run without the fans on at lower loads? How comes - they're just able to run without generating a lot of heat? So for browsing the net etc. the fan normally isn't even on?

Anyway. If it's between the XFX XXX 750 watt and the AX650 watt, I'd be bettering off choosing the latter, cos of warranty time, quality of build and noise level... hmm? The extra watts from the XFX is not something I'm likely to gain from, even with a high level GPU and CPU in the future?

I'm also very close to just say "F__ this" and buy the AX750 watt Doing hardware research is hell.

It's the way they are designed. They generate little heat at low loads, so the fan is turned off, and ramps up when the load goes up.



I would get the AX750 / XXX 750W only if you are thinking of crossfire / SLI later on. It's true Corsair could well be less of a hassle than Seasonic or XFX in case of malfunction / returns. And if you value their extended warranty, then you would also value good customer support.

So far I've been lucky and never needed RMA for anything. So I can't say first hand.

Hmm no not SLI, but just worried, if in, hmm 6 years the top CPU:s become more PSU demanding again and it becomes more standard with 2 GPU:s in the graphic cards (like the gtx590 today).
Or in other words I'd hope to use my AX not for 4-5 years but for 6-10 years I'm sure
Or will the ATX connectors be incompatible with the mobos then, I don't know
