Looking for a PSU worth the money

post #1 of 36
Thread Starter 
Hello there,

I am planning to make a couple of upgrades for my sig rig these holidays:

CPU - i5 2500k
Motherboard - ASrock Extreme3 Gen3
GPU - HD 6950 2GB Dirt 3 Edition
HDD - 1TB WDC Green SATA II
RAM - Vengeance Corsair 8GB 1600MHz CL9
DVD Drive - Samsung SH-222AB
Resolution - 1920 x 1080
CPU Cooler - Stock (might get a Coolermaster Hyper 212 +)

I need a Power supply. The Corsair AX 650 is pretty expensive, but if it is worth it I will buy it. Also, about efficiency. Is the power saving a huge difference between a TX 660 v2 bronze and an AX650 Gold?
The TX 650 would fit well for my budget - up to about 660 EUR. Without the PSU I will need to spend 577.96 for the parts needed, 300 EUR I pay and the rest is up to my parents.

So main points of interest in PSU for me:
  • Efficiency
  • Longevity
  • Quality
  • Modular / non modular - doesn't really matter.

Thanks in advance

Go for the XFX PSU's if you're on a budget. They're quality PSU's and internals are all Seasonic afaik.

The one in my sig is a good one, the Core/Pro Series are also pretty good, IIRC its slightly better than the XXX edition, however it's not modular.

What sire are you using? Maybe we could take a look and recommend you a few that'll fit your budget without hurting your wallet tongue.gif

Thanks for your response.

A bit pricey if you ask me. And the power supplies aren't sold in my country. How does this XFX PSU compare with the TX 650 v2?

EDIT: What sire?

Apologies, I meant what site will you be purchasing from?

As far as I know the XXX edition share the same internals as the SeaSonic S12II, therefore the XFX and Corsair are near identical internally.

I guess I was mistaken, the Core Edition is near identical as the V2.

Link the shop/s you'll be buying from and your budget in the local currency and/or Euro smile.gif

IIRC Corsair AX650 is based on the Seasonic X series design anyway. Both are strong performers, so if you need full modularity and are willing to pay a premium for the performance than go for it.

HX650 and TX650V2 are strong performers as well. TX650V2 uses a newer Seasonic design with DC-DC VRMs, whereas the HX650 does not.

Really though, you can't go wrong with any of them. All 4 are great PSUs.

Just posting to support the posts before mine, and to comment on something not addressed yet, which is the efficiency part -- the premium you pay for 80 Plus Gold units will take a long time to recoup based on the minute amount of cash you save in utility power compared to what an otherwise similar 80 Plus Bronze unit would draw from the wall. 80 Plus Bronze is already a very good level of efficiency. I generally recommend ignoring the whole efficiency thing so long as the unit you're getting is 80 Plus certified (and actually withstands its certification under professional testing). Efficiency should be the last thing on your mind unless you will be running the computer under load 24/7 (such as if you were building a dedicated Folding@Home computer).

I would get the Seasonic and not think twice if I were in your shoes. Never owned a better PSU. Don't think a better PSU exists in all honesty.

I will not have it 24/7.

So TX 650 v2 is by Seasonic, right? The Seasonic is about 50 EUR more. Is it worth the extra cash or is it just the efficiency that we pay for.

So the TX 650 v2 and the AX650 have no big difference in terms of efficiency. It is cheaper, which makes me think if it is also worse in terms of quality.

As you've already been told, your system only requires a 450W PSU, getting a 650W unit is pointless... had a look at your links and these are your best options..
Antec VP550P @ 56€, the best value unit on the market, Delta built, excellent regulation and ripple suppression, noisy at high loads
Antec HCG 520 @ 70€, Seasonic S12II Bronze inside, solid unit
Be Quiet L8 530 @ 72€, solid HEC built unit, modular
Thermaltake XT 570 @ 78€, better than the TXv2, CWT DSG inside(a variation or the same platform used by Corsair HX 750/850), excellent performance, modular
Be Quiet E9 500 @ 87€, FSP Aurum inside, will return Platinum efficiency at 230v(your case), inaudible
Super Flower Golden King 550 @ 117€, simply the best unit on the market at that output level, better than Seasonic X/Corsair AX, will return Platinum efficiency up to 650W DC @ 230v, will function in fanless mode at up to 550W DC(given your hardware, you'll never see the fan spinning), would power a second 6950 without any issues whatsoever, here's a review of the unit.
