My 700 watt OCZ just died, so I am in need of a new PSU. My system is: AMD Phenom II X4 955 clocked at 3.50 GHz, 8 GB DDR3 RAM, 4 HDD's, a optical drive and an Nvidia Geforce GTX 260. I really need to get a new power supply soon, but I really do not know much about the different brands. I am not sure how many watts I need, but with the OCZ 700, I had to run a supplemental supply just to power the GPU (12V). Any recommendations would be appreciated! I will want to use Newegg if possible, because I have an account with Shoprunner that gives me free shipping!

700W is good, but you dont need that much. Im pretty sure with your setup a 600W would do you fine, but to be on the safe side I would recommend at least a 650W.

I like these :D

The OCZ 700 did not have enough power output on the 12v rail to properly power the GTX260. I ended up purchasing a supplemental PSU to provide the GPU with enough power. Now when I look at the PSU's, what do I need to have on the 12v rail to power the GPU?

Who makes your gpu card? I know its GTX260, but does eVGA make it? etc..?

Hi,

NZXT is a brand that seems over looked but is highly rated. I am really happy with my NZXT 850w Gold, which I bought as they where out of Corsair products.

Nice! I have an nzxt case! The 850 gold is selling for $169.99 which is a bit high, but may be worth it!

For your GPU as long as you get a PSU with at least 2 x 6 Pin power connectors you are good.

I would recommend now to stick with at least 700W, but go for 750W-800W

Edit: oh and enough connections for your hard drives.

I have a Cooler Master Silent Pro 850w and it has been running 24/7 for more than a year without any issues or noise.

It is modular and can help you with that pesky cable management inside your case.

It's selling on NewEgg for $139 http://www.newegg.com/Product/Product.aspx?Item=N82E16817171048

The 700w version is $10 cheaper but I don't see any benefit for that little difference.

I have that exact same one, and it's an excellent PSU. Very satisfied. :yes:

Hello guys,

Recently I've checked the hardware monitor in bios and the numbers were:

  • CPU Voltage: 1.184v
  • 3.3V Voltage: 3.360v
  • 5V Voltage: 5.136v / 5.160v
  • 12V Voltage: 11.872v / 11.928v

So, after these numbers, you can see that 12v is lower than 12.

Should I change the PSU? If yes, can someone recommend modular Cooler Master PSU (because market in my country) for my configuration?

The ATX spec includes a 5% tolerance, so as long as you are between 12.6V and 11.4V, you should be okay. Plus the software programs that read those voltages aren't super accurate to begin with. You'd have to physically check it with a multimeter.

If you're looking for a new PSU, this is the one I have, and it's rock solid:

Thank you for the info.

So, I can go with the SIlent Pro PSU's.

850W - isn't a overkill for my config (including the future upgrades)?

It probably is a bit overkill. But if you someday want to run crossfire or SLI, you'd be happy you had the extra PSU headroom.

When I was running 570s in SLI, the 750W I had at the time, really struggled.

If you're on a budget, I'd say yeah it's unnecessary. But if you upgrade it now, it's one less thing to upgrade later.

    • Researchers claim Microsoft's quantum breakthrough is flawed by basic Python errors by Karthik Mudaliar Microsoft's aggressive roadmap to deliver a commercial quantum supercomputer by 2029 has now hit a bit of a snag, and it's not because of a complex sub-zero dilution refrigerator, but rather because of a few lines of basic Python code. A new critique published in the scientific journal Nature argues that simple software errors effectively manufactured the breakthrough that Microsoft's foundational research claimed back in 2025 into Majorana-based topological qubits. Topological quantum computing, the path that Microsoft chose for its research, relies on creating and controlling "Majorana zero modes." These are exotic quasiparticles that theoretically offer vastly superior error resistance compared to the highly sensitive superconducting qubits currently being championed by rivals like Google and IBM. However, physically proving you have created these particles requires sifting through massive amounts of complex electrical conductance data to isolate a specific "topological gap." Because of the sheer volume of data, physicists rely heavily on custom software pipelines to process the results. This is where the Python scripts come in. Now, according to the critique, Microsoft’s data processing software contained fundamental programming errors that ultimately skewed the published results. By mishandling data arrays or deploying incorrect logic within the Python script, the software supposedly discarded "noisy" or contradictory data. Which is why it only highlighted the specific electrical measurements that supported the topological-gap claim. The researchers behind the critique argued that this makes the findings invalid, suggesting the heralded "quantum leap" was actually a false positive generated by bad code and not a product of groundbreaking physics. However, Microsoft is pushing back hard against these allegations. The Redmond giant has formally rejected the criticism, saying that it's just a minor anomaly rather than a fatal flaw. According to the company, while there may have been a minor oversight in the data parsing scripts, it does not alter the fundamental reality of their physical experiment. Just weeks ago, Microsoft unveiled the Majorana 2 quantum processor, a milestone so significant that the company boldly accelerated its timeline for a commercial quantum supercomputer from 2035 down to 2029. But the new software allegations reopen an old wound. Microsoft's quantum division faced a remarkably similar crisis when a landmark 2018 paper on Majorana particles was famously retracted in 2021 after independent physicists discovered the data had been inappropriately cropped. That historical baggage makes the current Python-related allegations particularly sensitive. If the foundational math and data processing for the 2025 breakthrough are genuinely flawed, the highly anticipated 2029 commercial timeline could easily be delayed or, worse, cancelled.
